The author is: the_authornHealth Status: Cancer Mortality (M) 2017. [Compare countries including Canada and Canadian Provinces]
Dataset: from CIHI, Canada. The same information plotted with different charts. Data files are also attached at the bottom. If you see any mistakes, or if you need more information, feel free to inform us
['Measurement units used: Age-standardized rate per 100,000 males. Heatmap might show relative comparisons; not absolute values. The primary goal of these visualizations are to compare. If units are not provided, interpret them as relative values']
These are outputs from a small tool developed on 2019. The tool can generate many more of such plots easily, and will work with data for other purpose

Learn some Centos/Redhat Linux: RHCE: MariaDB Administration on Redhat/Fedora/CentOS #nothing
The author is: the_authornRHCE: MariaDB Administration on Redhat/Fedora/CentOS
Check if mariaDB is installed or not
130 yum list installed | grep ^mariadb
mariaDB originated from MySQL - after MySQL Got Bought by Oracle
133 yum list installed | grep ^mariadb
I see - installed though not completely
Output:
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
There are two other components: mariaDB - client component. MariaDB-server: Server Component
The MariaDB packages:
138 mariadb-bench.x86_64 mariadb-devel.x86_64 mariadb-server.x86_64 mariadb-test.x86_64 mariadb.x86_64
Install all packages at once
139 yum install mariadb*
140 yum list installed | grep ^mariadb
Now, I see the following, after I have installed - all MariaDB packages available in my system
mariadb.x86_64 1:5.5.52-1.el7 @local
mariadb-bench.x86_64 1:5.5.52-1.el7 @local
mariadb-devel.x86_64 1:5.5.52-1.el7 @local
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
mariadb-server.x86_64 1:5.5.52-1.el7 @local
mariadb-test.x86_64 1:5.5.52-1.el7 @local
MariaDB Configuration Files
149 ls /etc/my.cnf
150 ls /etc/my.cnf.d/*
The files
/etc/my.cnf.d/client.cnf /etc/my.cnf.d/mysql-clients.cnf /etc/my.cnf.d/server.cnf
153 vim /etc/my.cnf
154 vim /etc/my.cnf.d/client.cnf
155 vim /etc/my.cnf.d/server.cnf
156 vim /etc/my.cnf.d/mysql-clients.cnf
157 main config file /etc/my.cnf
158 grep -v ^# /etc/my.cnf : will show lines that are not comments
159 grep -v ^# /etc/my.cnf
The content of my.cnf : some lines are self explanatory
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
MariaDB messages are logged at: /var/log/mariadb/mariadb.log
MySQL Specific Selinux Contexts
171 ps -eZ | grep mysqld
I do not see anything as mysqld/maridb is not running
178 systemctl start mariadb.service
179 systemctl enable mariadb.service
180 ps -eZ | grep mysqld
now the output:
system_u:system_r:mysqld_safe_t:s0 4428 ? 00:00:00 mysqld_safe
system_u:system_r:mysqld_t:s0 4585 ? 00:00:00 mysqld
184 mysqld runs on it's own domain mysqld_t
Related Selinux file type: mysql_exec_t
etc_t is for /etc/my.cnf.d
mysql_db_t is for /var/lib/mysql/
mysql_log_t is for /var/log/mariadb/
189 ll -dZ /usr/libexec/mysqld /etc/my.cnf.d /var/lib/mysql /var/log/mariadb
The output - please note the Selinux Contexts in the output
drwxr-xr-x. root root system_u:object_r:mysqld_etc_t:s0 /etc/my.cnf.d
-rwxr-xr-x. root root system_u:object_r:mysqld_exec_t:s0 /usr/libexec/mysqld

drwxr-x---. mysql mysql system_u:object_r:mysqld_log_t:s0 /var/log/mariadb
Corresponding Selinux Port Type: mysql_port_t
196 semanage port -l | grep mysqld
output:
mysqld_port_t tcp 1186, 3306, 63132-63164
Related Selinux Booleans: mysql_connect_any, selinuxuser_mysql_connect_enabled
200 getsebool -a | grep mysql
I see the output
mysql_connect_any --> off
selinuxuser_mysql_connect_enabled --> off
To install MariaDB-Server:
205 yum -y install mariadb-server
already installed. we installed with yum -y install mariadb* [installed everything together]
207 systemctl enable mariadb
We can run mysql_secure_installation - to secure our MariaDB installation
209 mysql_secure_installation
The Output: from mysql_secure_installation command
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Enable MariaDB through Firewall and Allow traffic on Port 3306 - default mysql port
218 firewall-cmd --add-service=mysql --perm
220 firewall-cmd --reload
221 systemctl start mariadb
222 systemctl status mariadb
223 start mysql/mariadb
Run MySQL
224 mysql -u root -p
mysqldump is used to backup a database
mysql command can be used to restore a database
you can even use IDEs such as MySQL Workbench to backup and restore MySQL Databases
228 mysql -u root -p
229 mysqldump -u root -p testsayed > testsayeddb.sql
to restore - you need to use < testsayeddb.sql
231 mysql -u root -p testsayed < testsayeddb.sql
Backup and Restore MySQL Database
You can backup multiple databases at once, you can even backup some tables or other database objects using mysqldump
similarly, you can restore multiple databases at the same time using mysql command
just use multiple datbase or database object names with NO comma - one after another
235 mysqldump -u root -p DB1 DB2 DB3 > alldb.sql
when you use restore and give the sql file - if you use db name or table name before < then only that part will be restored irrespective hiow much data is there on the file
example
238 mysql -u root -p DB1 tbl1 < alldb.sql ;
you can use --all-databases or --databases with mysqldump command

Learn some Centos/Redhat Linux: RHCE: MariaDB Administration on Redhat/Fedora/CentOS #nothing
The author is: the_authornRHCE: MariaDB Administration on Redhat/Fedora/CentOS
Check if mariaDB is installed or not
130 yum list installed | grep ^mariadb
mariaDB originated from MySQL - after MySQL Got Bought by Oracle
133 yum list installed | grep ^mariadb
I see - installed though not completely
Output:
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
There are two other components: mariaDB - client component. MariaDB-server: Server Component
The MariaDB packages:
138 mariadb-bench.x86_64 mariadb-devel.x86_64 mariadb-server.x86_64 mariadb-test.x86_64 mariadb.x86_64
Install all packages at once
139 yum install mariadb*
140 yum list installed | grep ^mariadb
Now, I see the following, after I have installed - all MariaDB packages available in my system
mariadb.x86_64 1:5.5.52-1.el7 @local
mariadb-bench.x86_64 1:5.5.52-1.el7 @local
mariadb-devel.x86_64 1:5.5.52-1.el7 @local
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
mariadb-server.x86_64 1:5.5.52-1.el7 @local

MariaDB Configuration Files
149 ls /etc/my.cnf
150 ls /etc/my.cnf.d/*
The files

157 main config file /etc/my.cnf
158 grep -v ^# /etc/my.cnf : will show lines that are not comments
159 grep -v ^# /etc/my.cnf
The content of my.cnf : some lines are self explanatory

MySQL Specific Selinux Contexts
171 ps -eZ | grep mysqld
I do not see anything as mysqld/maridb is not running
178 systemctl start mariadb.service
179 systemctl enable mariadb.service
180 ps -eZ | grep mysqld
now the output:

system_u:system_r:mysqld_t:s0 4585 ? 00:00:00 mysqld
184 mysqld runs on it's own domain mysqld_t
Related Selinux file type: mysql_exec_t
etc_t is for /etc/my.cnf.d
mysql_db_t is for /var/lib/mysql/
mysql_log_t is for /var/log/mariadb/
189 ll -dZ /usr/libexec/mysqld /etc/my.cnf.d /var/lib/mysql /var/log/mariadb
The output - please note the Selinux Contexts in the output
drwxr-xr-x. root root system_u:object_r:mysqld_etc_t:s0 /etc/my.cnf.d

Related Selinux Booleans: mysql_connect_any, selinuxuser_mysql_connect_enabled
200 getsebool -a | grep mysql
I see the output
mysql_connect_any --> off
selinuxuser_mysql_connect_enabled --> off
To install MariaDB-Server:
205 yum -y install mariadb-server
already installed. we installed with yum -y install mariadb* [installed everything together]
207 systemctl enable mariadb
We can run mysql_secure_installation - to secure our MariaDB installation
209 mysql_secure_installation
The Output: from mysql_secure_installation command
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Enable MariaDB through Firewall and Allow traffic on Port 3306 - default mysql port
218 firewall-cmd --add-service=mysql --perm
220 firewall-cmd --reload
221 systemctl start mariadb
222 systemctl status mariadb
223 start mysql/mariadb
Run MySQL
224 mysql -u root -p
mysqldump is used to backup a database
mysql command can be used to restore a database
you can even use IDEs such as MySQL Workbench to backup and restore MySQL Databases
228 mysql -u root -p
229 mysqldump -u root -p testsayed > testsayeddb.sql
to restore - you need to use < testsayeddb.sql
231 mysql -u root -p testsayed < testsayeddb.sql
Backup and Restore MySQL Database
You can backup multiple databases at once, you can even backup some tables or other database objects using mysqldump
similarly, you can restore multiple databases at the same time using mysql command
just use multiple datbase or database object names with NO comma - one after another
235 mysqldump -u root -p DB1 DB2 DB3 > alldb.sql
when you use restore and give the sql file - if you use db name or table name before < then only that part will be restored irrespective hiow much data is there on the file
example
238 mysql -u root -p DB1 tbl1 < alldb.sql ;
you can use --all-databases or --databases with mysqldump command

Learn some Centos/Redhat Linux: RHCE: MariaDB Administration on Redhat/Fedora/CentOS #nothing
The author is: the_authornRHCE: MariaDB Administration on Redhat/Fedora/CentOS
Check if mariaDB is installed or not
130 yum list installed | grep ^mariadb
mariaDB originated from MySQL - after MySQL Got Bought by Oracle
133 yum list installed | grep ^mariadb
I see - installed though not completely
Output:
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
There are two other components: mariaDB - client component. MariaDB-server: Server Component
The MariaDB packages:
138 mariadb-bench.x86_64 mariadb-devel.x86_64 mariadb-server.x86_64 mariadb-test.x86_64 mariadb.x86_64
Install all packages at once
139 yum install mariadb*
140 yum list installed | grep ^mariadb
Now, I see the following, after I have installed - all MariaDB packages available in my system
mariadb.x86_64 1:5.5.52-1.el7 @local
mariadb-bench.x86_64 1:5.5.52-1.el7 @local
mariadb-devel.x86_64 1:5.5.52-1.el7 @local
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
mariadb-server.x86_64 1:5.5.52-1.el7 @local
mariadb-test.x86_64 1:5.5.52-1.el7 @local
MariaDB Configuration Files
149 ls /etc/my.cnf
150 ls /etc/my.cnf.d/*
The files
/etc/my.cnf.d/client.cnf /etc/my.cnf.d/mysql-clients.cnf /etc/my.cnf.d/server.cnf
153 vim /etc/my.cnf
154 vim /etc/my.cnf.d/client.cnf
155 vim /etc/my.cnf.d/server.cnf
156 vim /etc/my.cnf.d/mysql-clients.cnf
157 main config file /etc/my.cnf
158 grep -v ^# /etc/my.cnf : will show lines that are not comments
159 grep -v ^# /etc/my.cnf
The content of my.cnf : some lines are self explanatory
[mysqld]

socket=/var/lib/mysql/mysql.sock
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
MariaDB messages are logged at: /var/log/mariadb/mariadb.log
MySQL Specific Selinux Contexts
171 ps -eZ | grep mysqld
I do not see anything as mysqld/maridb is not running
178 systemctl start mariadb.service
179 systemctl enable mariadb.service
180 ps -eZ | grep mysqld
now the output:
system_u:system_r:mysqld_safe_t:s0 4428 ? 00:00:00 mysqld_safe
system_u:system_r:mysqld_t:s0 4585 ? 00:00:00 mysqld
184 mysqld runs on it's own domain mysqld_t
Related Selinux file type: mysql_exec_t
etc_t is for /etc/my.cnf.d
mysql_db_t is for /var/lib/mysql/
mysql_log_t is for /var/log/mariadb/
189 ll -dZ /usr/libexec/mysqld /etc/my.cnf.d /var/lib/mysql /var/log/mariadb
The output - please note the Selinux Contexts in the output
drwxr-xr-x. root root system_u:object_r:mysqld_etc_t:s0 /etc/my.cnf.d
-rwxr-xr-x. root root system_u:object_r:mysqld_exec_t:s0 /usr/libexec/mysqld

drwxr-x---. mysql mysql system_u:object_r:mysqld_log_t:s0 /var/log/mariadb
Corresponding Selinux Port Type: mysql_port_t
196 semanage port -l | grep mysqld
output:
mysqld_port_t tcp 1186, 3306, 63132-63164
Related Selinux Booleans: mysql_connect_any, selinuxuser_mysql_connect_enabled
200 getsebool -a | grep mysql
I see the output
mysql_connect_any --> off
selinuxuser_mysql_connect_enabled --> off
To install MariaDB-Server:
205 yum -y install mariadb-server
already installed. we installed with yum -y install mariadb* [installed everything together]
207 systemctl enable mariadb
We can run mysql_secure_installation - to secure our MariaDB installation
209 mysql_secure_installation
The Output: from mysql_secure_installation command
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Enable MariaDB through Firewall and Allow traffic on Port 3306 - default mysql port
218 firewall-cmd --add-service=mysql --perm
220 firewall-cmd --reload
221 systemctl start mariadb
222 systemctl status mariadb
223 start mysql/mariadb
Run MySQL
224 mysql -u root -p
mysqldump is used to backup a database
mysql command can be used to restore a database
you can even use IDEs such as MySQL Workbench to backup and restore MySQL Databases
228 mysql -u root -p
229 mysqldump -u root -p testsayed > testsayeddb.sql
to restore - you need to use < testsayeddb.sql
231 mysql -u root -p testsayed < testsayeddb.sql
Backup and Restore MySQL Database
You can backup multiple databases at once, you can even backup some tables or other database objects using mysqldump
similarly, you can restore multiple databases at the same time using mysql command
just use multiple datbase or database object names with NO comma - one after another
235 mysqldump -u root -p DB1 DB2 DB3 > alldb.sql
when you use restore and give the sql file - if you use db name or table name before < then only that part will be restored irrespective hiow much data is there on the file
example
238 mysql -u root -p DB1 tbl1 < alldb.sql ;
you can use --all-databases or --databases with mysqldump command

Learn some Centos/Redhat Linux: RHCE: MariaDB Administration on Redhat/Fedora/CentOS #nothing
The author is: the_authornRHCE: MariaDB Administration on Redhat/Fedora/CentOS
Check if mariaDB is installed or not
130 yum list installed | grep ^mariadb
mariaDB originated from MySQL - after MySQL Got Bought by Oracle
133 yum list installed | grep ^mariadb
I see - installed though not completely
Output:
mariadb-libs.x86_64 1:5.5.52-1.el7 @anaconda
There are two other components: mariaDB - client component. MariaDB-server: Server Component
The MariaDB packages:
138 mariadb-bench.x86_64 mariadb-devel.x86_64 mariadb-server.x86_64 mariadb-test.x86_64 mariadb.x86_64
Install all packages at once
139 yum install mariadb*
140 yum list installed | grep ^mariadb
Now, I see the following, after I have installed - all MariaDB packages available in my system
mariadb.x86_64 1:5.5.52-1.el7 @local
mariadb-bench.x86_64 1:5.5.52-1.el7 @local
mariadb-devel.x86_64 1:5.5.52-1.el7 @local

I do not see anything as mysqld/maridb is not running
178 systemctl start mariadb.service
179 systemctl enable mariadb.service
180 ps -eZ | grep mysqld
now the output:

mysql_log_t is for /var/log/mariadb/
189 ll -dZ /usr/libexec/mysqld /etc/my.cnf.d /var/lib/mysql /var/log/mariadb
The output - please note the Selinux Contexts in the output

Related Selinux Booleans: mysql_connect_any, selinuxuser_mysql_connect_enabled
200 getsebool -a | grep mysql
I see the output
mysql_connect_any --> off

To install MariaDB-Server:
205 yum -y install mariadb-server
already installed. we installed with yum -y install mariadb* [installed everything together]
207 systemctl enable mariadb
We can run mysql_secure_installation - to secure our MariaDB installation
209 mysql_secure_installation
The Output: from mysql_secure_installation command
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Enable MariaDB through Firewall and Allow traffic on Port 3306 - default mysql port
218 firewall-cmd --add-service=mysql --perm
220 firewall-cmd --reload
221 systemctl start mariadb
222 systemctl status mariadb
223 start mysql/mariadb
Run MySQL
224 mysql -u root -p
mysqldump is used to backup a database
mysql command can be used to restore a database
you can even use IDEs such as MySQL Workbench to backup and restore MySQL Databases
228 mysql -u root -p
229 mysqldump -u root -p testsayed > testsayeddb.sql
to restore - you need to use < testsayeddb.sql
231 mysql -u root -p testsayed < testsayeddb.sql
Backup and Restore MySQL Database
You can backup multiple databases at once, you can even backup some tables or other database objects using mysqldump
similarly, you can restore multiple databases at the same time using mysql command
just use multiple datbase or database object names with NO comma - one after another
235 mysqldump -u root -p DB1 DB2 DB3 > alldb.sql
when you use restore and give the sql file - if you use db name or table name before < then only that part will be restored irrespective hiow much data is there on the file
example
238 mysql -u root -p DB1 tbl1 < alldb.sql ;
you can use --all-databases or --databases with mysqldump command

To install MariaDB-Server:
205 yum -y install mariadb-server
already installed. we installed with yum -y install mariadb* [installed everything together]
207 systemctl enable mariadb
We can run mysql_secure_installation - to secure our MariaDB installation
209 mysql_secure_installation
The Output: from mysql_secure_installation command
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Enable MariaDB through Firewall and Allow traffic on Port 3306 - default mysql port
218 firewall-cmd --add-service=mysql --perm
220 firewall-cmd --reload
221 systemctl start mariadb
222 systemctl status mariadb
223 start mysql/mariadb
Run MySQL
224 mysql -u root -p
mysqldump is used to backup a database
mysql command can be used to restore a database
you can even use IDEs such as MySQL Workbench to backup and restore MySQL Databases
228 mysql -u root -p
229 mysqldump -u root -p testsayed > testsayeddb.sql
to restore - you need to use < testsayeddb.sql
231 mysql -u root -p testsayed < testsayeddb.sql
Backup and Restore MySQL Database
You can backup multiple databases at once, you can even backup some tables or other database objects using mysqldump
similarly, you can restore multiple databases at the same time using mysql command
just use multiple datbase or database object names with NO comma - one after another
235 mysqldump -u root -p DB1 DB2 DB3 > alldb.sql
when you use restore and give the sql file - if you use db name or table name before < then only that part will be restored irrespective hiow much data is there on the file
example
238 mysql -u root -p DB1 tbl1 < alldb.sql ;
you can use --all-databases or --databases with mysqldump command

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

to restore - you need to use < testsayeddb.sql
231 mysql -u root -p testsayed < testsayeddb.sql
Backup and Restore MySQL Database
You can backup multiple databases at once, you can even backup some tables or other database objects using mysqldump
similarly, you can restore multiple databases at the same time using mysql command
just use multiple datbase or database object names with NO comma - one after another
235 mysqldump -u root -p DB1 DB2 DB3 > alldb.sql
when you use restore and give the sql file - if you use db name or table name before < then only that part will be restored irrespective hiow much data is there on the file
example
238 mysql -u root -p DB1 tbl1 < alldb.sql ;
you can use --all-databases or --databases with mysqldump command

Basic Information on Exception Handling in .Net #.Net Web Applications
Brought from our old site: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1356&title=Basics%20of%20Exception%20Handling%20in%20.Net
Basic Information on Exception Handling in .Net
Why exception handling? In your applications, unexpected error situations may occur that are out of your application scope and your application logic. These are actually external to your application. For example, while you are reading a file from hard drive, the file may not be there; or the remote server may be too busy or unavailable to get back to you with the result of your query. Exception handling addresses such situations.
How can you handle such situations:
- Use try, catch, finally structure to address such situations
- Put the code where, you are anticipating an exception inside a try{} block. Put the code to handle the error situation in catch (Exception ex) {} blocks. You can have multiple catch blocks where each one will address a specific type of exception situation.
- One more note, the code block where exception may occur may need to execute some logic/code whether an exception occurs or or not such as closing a file, closing the database connection. To accomplish this, you can use a finally block. A finally block is always executed, regardless of whether an exception is thrown or not.
- When an exception occurs, the events are thrown by the environment. You need to address that if you want to. Else, your users will see the errors and will cause a bad user experience.
- You can even throw exceptions on your own in your code. But why? say if you anticipate that there will be some error situations that are not external but related to your application logic and you actually do not want to handle those situations (serve some services in those situations for example) in your application. You can just throw exceptions and think that these are the conditions; you do not want to support in your application. Throw exception and provide some generalized response to your visitors.
- You can also handle exceptions throw the web objects' built in error events such as Page_Error, Global_Error, Application_Error.
- In certain situations, You can take advantage of the error pages of the webserver to provide useful information to your visitors. You can replace the default error pages of your web-server and provide customized error pages to your visitor
- Finally, you can use tracing to log the error events. Monitor the tracing to understand which types of situations occur more frequently than others. And find out a solution and apply the solution
- It is possible to turn on and off this tracing without modifying the application code. You can make use of the web.config file configurations
Regarding error pages, you can provide your custom error pages for the standard HTTP error codes. Some codes are given below:204:No Content, 301:Moved, Moved Permanently, 302: Found, Redirect, 400:bad request, 401:unauthorized, 403: forbidden, 404:not found, 408:request time out, 500:internal server error, 503:service unavailable, 505:Http version not supported.
You can also make use of the errorPage attribute of the Page object to define an error page for the exceptions of that particular page. Page level settings override the application level settings (as provided by web.config file)
- How to enable application level tracing: use something similar as below in your web.config file
{ and } are used instead of < and > respectively. {configuration} {system.web} {trace enabled="true" requestLimit="40" localOnly="false"/} {/system.web} {/configuration} - to enable tracing for a particular page, use the trace property of the Document object
- how to write tracing information to the trace log: Trace.Warn()

Allow Page Access only to the Logged in Users #.Net Web Applications
Brought from our old site: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1349&title=Allow%20Page%20Access%20only%20to%20the%20Logged%20in%20Users
Allow Page Access only to the Logged in Users
- It's common across many sites that you allow certain pages of your site only to the logged in users.
- Here, I am providing a simple way to do that in your site
- The main idea is, when users' credentials are verified, we store the information in the session object. Later, if a restricted page is being accessed, we check if the user is a verified/(logged in) user, if so we allow him access otherwise not
- You can use individual session variables to store some information about the user and logged in status. However, that may not be a great way. Better, to use an object to store user information and login status information. Then throw that object to the session variable.
- You will need to use this object (session variable) across your site in all restricted pages; hence, using global variables concept may help.
- Here, I will present code that will show you 1. a class to store user information 2. global variables class implementing the method to check if any user is logged in [from anywhere in your application] 3. a login form that will create a user object to store user information upon successful login and throw that object in session 4. a test restricted page that will check if any user is logged - if yes, go forward else redirect the user to the login page
- The class for storing user information is as below. You can keep the class in the App_Code folder
- Now the Global Variables Class. You can keep the class in the App_Code folder
- Now the login form (frontend) code
- Now the login form backend code. Check the method that checks for login credentials and create the loggedinuser object
- The test page that will restrict access for not logged in users.

Encryption and .Net #.Net Web Applications
Brought from our old site: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1355&title=Encryption%20and%20.Net
Encryption and .Net
Dot net provides rich support for data encryption. the namespace System.Security.Cryptography includes the encryption features.
There are three primary concepts related to encryption such as Hashing, Symmetric Encryption, and Asymmetric encryption. A hash is a data fingerprint, a small data that represents the uniqueness of a large block of data. In Symmetric Encryption, a single key is used for both encryption and decryption. In Asymmetric encryption, two different keys are used, one for encryption and another one for decryption. In real world applications, a combination of all three methods are used to provide better security.
A digital transmission of a check can be as follows: create the hash of the check, encrypt the hash with the public key using asymmetric encryption, apply the encrypted hash on the document, encrypt the symmetric encryption key with asymmetric encryption method, encrypt the check with symmetric encryption, transmit the encrypted key and encrypted document to the receiver
Hash Example
hash = New Encryption.Hash(Encryption.Hash.Provider.CRC32)
data = New Encryption.Data("Hash Browns")
hash.Calculate(data)
Symmetric example:
sym = New Encryption.Symmetric(Encryption.Symmetric.Provider.Rijndael)
key = New Encryption.Data("Pass")
Encryption.Data encryptedData;
encryptedData = sym.Encrypt(New Encryption.Data("Secret"), key)
string base64EncryptedString = encryptedData.ToBase64
Asymmetric Example
asym = New Encryption.Asymmetric
pubkey = New Encryption.Asymmetric.PublicKey
privkey = New Encryption.Asymmetric.PrivateKey
asym.GenerateNewKeyset(pubkey, privkey)
secret = "ancient chinese"
Encryption.Data encryptedData
encryptedData = asym.Encrypt(New Encryption.Data(secret), pubkey)
Encryption.Data decryptedData
asym2 = New Encryption.Asymmetric
decryptedData = asym2.Decrypt(encryptedData, privkey)

Simple Ajax Applications in C# (ASP.Net) #.Net Web Applications
Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1347&title=Simple%20Ajax%20Applications%20in%20C#%20(ASP.Net)
Simple Ajax Applications in C# (ASP.Net)
Note:asmx web-service might be more appropriate in some/many cases
- If you are coming from PHP or Java Platform where you use JavaScript or jQuery to provide Ajax functionality, you still can use those strategies in ASP.net to provide Ajax functionality
- Check our short note on Ajax using JavaScript. In .Net, you just have to call the JavaScript function (that implements Ajax functionality) on the event you want the Ajax functionality. However, you do not use runat="server".
- Another approach is Using Ajax Server Controls such as ScriptManager, ScriptManagerProxy, UpdatePanel, ContentPanel, UpdateProxy
- You can find these Ajax controls at the Toolbox under Ajax Extensions
- You can grab them and place on your form, you can grab and place on the code, or you can write them in your code [whatever you are used to]
- And yes, you could use JQuery as well. JQuery uses a wrapper on JavaScript functionality and makes the life of the developer way easier
- In this short note, I will show a simple example of using Ajax Server Controls, also show you the code to invoke Ajax functionality using JavaScript
- Now take a look at the simple application interface below. The application will calculate sum, difference, and multiplication of two numbers without refreshing the page. We will calculate immediately, also will show the situation when the calculation may take a little more time
- The idea is simple, you need to add a ScriptManager control. If you use master pages, and the situation becomes that you need to place two ScriptManagers, just place one ScriptManager in the Master and use ScriptManagerProxy in the content page
- use UpdatePanel around the controls that will be refreshed without the page being refreshed
- Use UpdateProgress control, when you know that the operation will take some time. Use this control to inform the user that the operation is under progress
- Now the sample application interface
- Now the Form code
- Now the backend code
- Now an example on how to implement Ajax functionality in C# in ASP.net using JavaScript. It just displays current date time but using Ajax and without refreshing the page. Just go through the code

Creating your own Class in C# in ASP.net
- It is kind of simple. You need to create a class library. The class library will create a dll file. From your project, you need to add reference to the dll file. Then you will be able to use the classes and methods of the class library.
- Check the following code. One is a sample class library and another one is how to use the class. The class library implements two methods such as add and subtract (to add or subtract two numbers). The project uses the namespace [class library] and calls these methods
- You can get the dll file in the bin/debug or bin/release folder under your class library project
- You can right click on your project/website [in solution explorer], and click Add Reference, then click browse and select the dll file created
- Check the class library below
- Check the Form in picture. This form uses the class library.
- Check the Form Code to use the Library
- Check the Backend Form Code to use the Library

ASP.Net Validation Control Examples. Just check the code below
Some notes
- RequiredFieldValidator: is used to check that a field is filled up
- CompareValidator: Compare the value of a field with another field or data
- RangeValidator: Compares the data is within a given range
- RegularExpressionValidator: Domain name syntax, email addtress syntax
- ValidationSummary: Display all validation errors in a summary box
- CompareValidator: Write your own custom validation rules and display the outcome
- Remember
- You can display error on the side of the control
- You can display error under the control
- The example used both just for example
- The Text property is the output that comes just where the validation control is placed. ErrorMessage propert is for the ValidationSummary
- If you just want the Validation Summary output, use Display="none" for the validation control (not the summarycontrol) itself
- the code can be seen at http://salearningschool.com/samples/validate.txt as well

Manipulating Configuration Parameters: For example Variables in web.config #.Net Web Applications
Brought from (our old site): http://salearningschool.com/displayArticle.php?table=Articles&articleID=1324&title=Manipulating%20Configuration%20Parameters:%20For%20example%20Variables%20in%20web.config
To access a variable value, you can use the following type of code
string statusr = WebConfigurationManager.AppSettings["userLoginStatus"].ToString();
You will need to use: using System.Web.Configuration; or you can write as follows: string statusr = System.Web.Configuration.WebConfigurationManager.AppSettings["userLoginStatus"].ToString();
What about if you want to change the values of the variables in the web.config file. Check the code below:
//Compiled
Configuration myConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
//change values for the variables in the AppSettings section
myConfig.AppSettings.Settings["userLoginStatus"].Value = "1";
//change values for the connection strings section
myConfig.ConnectionStrings.ConnectionStrings["myDatabaseName"].ConnectionString =
"Data Source=....";
myConfig.Save();
//will return you the new value
string statusr = WebConfigurationManager.AppSettings["userLoginStatus"].ToString();
The above code used:
System.Web.Configuration;
using System.Configuration;

Random Notes and simple code on Developing Web Sites (Applications) in ASP.net using C# #.Net Web Applications
Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1319&title=Random%20Notes%20and%20simple%20code%20on%20Developing%20Web%20Sites%20(Applications)%20in%20ASP.net%20using%20C#
And sure, pretty old article..
Random Notes and simple code on Developing Web Sites (Applications) in ASP.net using C#
- The information below primarily apply to the web page model of web-development in C#
- _PageStart.cshtml runs at each page start/open
- _AppStart.cshtml runs at the beginning of the application
- Syntax to use the Layout file: @{Layout = "/Shared/Layout.cshtml";}
- if you use this - @{Layout = /Shared/Layout.cshtml";} in the _PageStart.cshtml file, you will not need to use it at the top of each file
- You can use Microsoft Webmatrix, Visual Web Developer, or Visual Studio for web development
- Webmatrix, includes IIS Express, and also a database workspace where you can create and use compact SQL Server Databases
- DateTime.Now : will display current date and time
- You can connect to a database using var db = Database.Open("db_name");
- db = Database.Open("db_name"); will look for the database in the same workspace; if not found will use the connection parameter as defined in the web.config file to find and connect to database
- Executing a query: var queryString = "SELECT * FROM Product ORDER BY Name"; db.Query(queryString)
- Accessing each row from a rowset of data as returned from database:
foreach(var entry in db.Query((queryString))) { @entry.Id, @entry.Name } - if (IsPost) : will check if a form is submitted by POST or not
- username = Request.Form["username"]; Will retrieve username from the Request object [submitted form with control named username]
- A basic login authentication code can be as follows
var username = ""; var password = ""; var ErrorMessage = ""; // If this is a POST request, validate and process data if (IsPost){ username = Request.Form["username"]; password = Request.Form["password"]; if (username.IsEmpty() || password.IsEmpty()){ ErrorMessage = "You must specify a username and password."; }else{ // Login, Navigate back to the homepage and exit if (WebSecurity.Login(username, password, false)){ Response.Redirect("~/"); } else{ ErrorMessage = "Login failed"; } } } @if (ErrorMessage!="") { @ErrorMessage, Please correct the errors and try again. } - Execute an Insert Statement: db.Execute("INSERT INTO UserProfile (Email) VALUES (@0)", email);
- WebSecurity object can be used for the security of your web-site (application) such as user authentication, block a page until a user is authenticated
- Block user if he is not logged in [can be added at the top of the page to be blocked]
@{ if (!WebSecurity.IsAuthenticated) Response.Redirect("~/Login"); //redirect to login page } - WebSecurity.InitializeDatabaseConnection("db_name", "profile_of_the_users_table", "UserId", "Email", true);
- WebSecurity.CreateAccount(email, password, false);

Razor, Web-page Model, Web-Application Development in C# #.Net Web Applications
Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1320&title=Razor,%20Web-page%20Model,%20Web-Application%20Development%20in%20C# (written long back)
Razor, Web-page Model, Web-Application Development in C#
- Razor:a markup syntax to add server side code into ASP.net pages
- Razor example: Current time is @DateTime.Now
- Razor Code Syntax
Single statement block @{ var message = "Hello World"; } Inline expression or variable The message: @message Multi-statement block @{ var greeting = "Hello"; var currentTime = DateTime.Now; var greetMessage = greeting + " Current time is: " + currentTime; } The greeting is: @greetMessage - Some Razor functions mainly used in the Layout file [can be used in other files based on the function]: RenderPage() - render the content of a page, RenderBody(), RenderSection(section) - render the content of a section named section
- using _ at the beginning of a web-page name prevents it from being browsed from browser such as _header.cshtml, _Layout.cshtml
- In ASP.net, you can hide sensitive information by using the _AppStart.cshtml file. Here, you can keep database passwords, and email passwords. You can also keep your webmail server configuration.
- _AppStart.cshtm example
@{ WebMail.SmtpServer = "smtp.bizmail.yahoo.com"; WebMail.EnableSsl = true; WebMail.UserName = "sayed@justetc.net"; WebMail.Password = "password"; WebMail.From = "sayed@justetc.net"; } - Some folders as used in ASP.net web applications: App_Data - to keep database files, Images - image files, Scripts - JavaScript files for example, Shared - common files such as CSS files
- In a file path, ~ is used to indicate the virtual root folder.
- Server.MapPath, can convert a virtual path to a physical path
- @Href(cssPath), here cssPath is a variable for a path. You can use Href(cssPath) for the value of href attributes
- Page object methods: href (builds a url), RenderBody(), RenderPage(page), RenderSection(section), Write (object) - HTML Encoded string, WriteLiteral - No HTML encoding
- Page object properties: isPost, Layout, Page, Request, Server
- You can add properties to the Page object such as Page.Title; here Title is your own variable [not built in]
- Read from a physical file: File.ReadAllLines(filePath). You may want to use var filePath = Server.MapPath("~/file.txt");, to get the physical path from a virtual path
- File.ReadAllLines(filePath), can also be used to read excel csv files [comma delimited]
- Some ASP.net helpers: Helpers are just components. WebGrid, Chart, WebMail, and WebImage are some common helpers
- WebGrid helper example: webGrid = new WebGrid (data); grid.getHtml(); data for example can be the rows of a database table, GetHtml () - will render the data as a HTML table.
- Chart example
@{ var db = Database.Open("dbName"); var dbdata = db.Query("SELECT Name, Price FROM Product"); var myChart = new Chart(width: 600, height: 400) .AddTitle("Product Sales") .DataBindTable(dataSource: dbdata, xField: "Name") .Write(); } - The above example will create bar chart [column chart]
- if you want a pie chart as output, use .AddSeries(chartType:"Pie" in the above example
- You can use an Array, or XML data as the data feed for the Chartff
- Sending emails: WebMail.Send(to:"xyz@xyz.com", subject: "Email from - " + customerEmail, body: request
- Publish your web-site: Use the publish option from your IDE (Webmatrix, Visual Studio for Web)
- Manual publish: Make sure that the server side has the compatible ASP.net framework, copy all of your folders and files, copy the DLL files into the bin folder, copy SQL server DLL files, copy the database if appropriate

.Net: Globalizing Web Applications #.Net Web Applications
Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1145&title=.Net:%20Globalizing%20Web%20Applications
Three ways of globalizing web-applications
- Create one for each culture/language - usually the web-interfaces. Redirect to a web-site built based on the current culture
- Write one web-application but detect current culture, then change the user interface (texts, date time formats) to represent the current culture - dynamically
- Satellite Based: Use resource files to keep culture specific messages. One resource file for one culture. Resource files will be in the format: key = value/message. Use the keys in the user interfaces. The keys will be replaced with the messages/values as stored in the resource files - based on current culture.
- Best Approach: Satellite Based
- Current culture: as set in the browsers/operating systems - or give culture/language change option on a button click
- How to detect current culture: Use CultureInfo, Calendar, and comparison classes
- Setting culture in the web.config file: Use the globalization element of the web.config file. You can set properties for each culture
- Satellite Based
- set the id and runat attributes for all the user-interface elements that require translation
- create a fallback resource file to keep default strings (key=value) (displays by default or no culture is set or culture is not recognized)
- create resource file for each culture that you want to support
- Use the ResourceManager class to load the resource files
- write code to detect the user's current culture.
- Write code to load strings from the resource files and display them
- Example:
using System.Globalization using System.Threading using System.Resources protected ResourceManager gStrings = new ResourceManager( "JustEtcWebAppsCS.strings", typeof(Satellite).Assembly); .. .. .. head1.InnerHtml = gStrings.GetString("satellite.head1");

Providing Help in an ASP.Net Web-application #.Net Web Applications
Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1124&title=Providing%20Help%20in%20an%20ASP.Net%20Web-application
- Use the Tooltip attribute of the ASP.Net controls to display help in Tooltip text
- You can create HTML pages to provide/show help. Just as a simple web-page
- You can use Web Forms to display help information
- You can display help using HTML Help Viewer
- You can use the HTML Help Workshop as comes with the Visual Studio to create Help projects similar to the generic windows help. Use the workshop and create a help project. Compile the help project into one .chm file. Use the ShowHelp method of the Window object to open this file (as a help file). Such help files usually have three tabs such as Contents, Index, and Search.

Formatting Web-application output #.Net Web Applications
Brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1144&title=Formatting%20Web-application%20output
- You can apply CSS styles to format web-application output
- If you have the same styles defined in multiple places (for the same element), the styles defined closest to the element will be applied. The order, inline, page, global (however, you should not define the same class here and there arbitrarily...that is an another topic)
- You can create classes that can be applied to multiple elements
- Use the CssStyle/CssStyle attribute to apply a style class to a server control
- use the class attribute to apply a style class to an HTML element
- Yes, you need to create a style file, and link to it from your web-form
- You can click the style property of an element or the style property/attribute of the form to bring the Style Wizard to define/modify existing styles
- You can also use the 'Add Style Rule' option in the popup menu on the .css files to define new styles. Also, use the 'Synchronize Document Elements' from the popup menu if required

How to Build a Personal Web-site with ASP.Net #.Net Web Applications
Brought and updated from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=967&title=How%20to%20Build%20a%20Personal%20Web-site%20with%20ASP.Net%20(VS%202008,%20.Net%202.0/3.5)
This actually is an old way of doing.
- Video Tutorial on this topic
- Web-site Code used in this tutorial
- Steps
- Open visual studio (2008) IDE
- File -> new project -> Visual Basic -> Web -> ASP .Net Web Application
- Rename default.aspx to template.aspx
- Insert a table from the tool box
- Create three rows for the table: top, body, bottom
- Top Row: banner, slogan
- Body Row: three cell: left, right, middle: left for left menu, right for right menu/advertising code, middle for contents
- bottom: privacy, copyright, links to contact us
- Keep left menu, right menu, top banner, bottom/footer contents in separate files such as leftMenu.aspx, rightMenu.aspx, topBanner.aspx
- In the template.aspx use Response.WriteFile("file.aspx") to link to the left and right menu, the top banner, the bottom/footer. Change file.aspx to the right file name.
- Create the leftMenu.aspx, rightMenu.aspx, topBanner.aspx, bottom.aspx
- template.aspx is just the template file. We have two options in the left menu like Home and Companies, that point to index.aspx, and companies.aspx respectively. You have to create those files
- Now copy the template file, paste it, rename it to index.aspx. index.aspx will be the root file of your web-site. Change the body part of the index.aspx to add contents
- Copy the template.aspx file, paste it, rename it to companies.aspx. Change the body part of companies.aspx to add contents
- You can modify leftMenu.aspx to add more options in the left menu. For each option that links to a .aspx file you have to create the .aspx file using the template.aspx [unless already existing]
- Similarly, you can change your right menu contents by updating rightMenu.aspx
- Deployment:
- Can copy the aspx files in the right place under IIS
- or let VS 2008 to deploy - right click the project in the solution explorer, click on publish, select the path where you want to publish the website, publish it to a folder where IIS has access
- You may need to configure IIS a bit, create/identify this application as a .Net application. Otherwise, it may not work. Else, you can adjust/edit the files to make them work [remove some lines].
- Test the application

Financial Transaction: Java Data Type #1
Best data type for Financial Transactions: Object with two integer type variables. One for the dollars and another for the cents.
floating points are inappropriate as they suffer from round-off errors.
For financial software how to create a common class for contracts that multiple independent classes will satisfy?
Using interface
because
for independent class hierarchies
An interface is the only type that permits multiple class implementations
an abstract class cannot be the superclass of multiple class implementations
a concrete class cannot be the superclass of multiple class implementations
Inheritance in the Java programming language
A superclass may have multiple subclasses.
A class can not inherit from multiple superclasses.
An abstract class may only have one superclass.
Interfaces, unlike classes, may have any number of supertypes.
Any class may only have one superclass.

Web page design standards #10
Try to follow the following rules while creating a web-page.
1. Decide what you want to use HTML or XHTML. Better to go
with XHTML. Which XHTML? Strict or transitional? Go for
strict one, that way you will be in the most standard way.
2. If you are new into XHTML try transitional first, when you are
comfortable in Transitional style, switch to Strict.
Rememebr, strict will not support many non-standard tags
and coding you usually use, so it may sound a bit difficult.
3. Some XHTML rules
a. Simply use a Doctype.
b. Use lower case for all tags
c. enclose all attribute values
d. close all tags even
e. Try to use css for layout
f. Even assign values to empty attributes like checked='checked', readonly='true'
g. nest attributes correctly
4. Page Layout
Most recent and most standard way is to use pure css (div,span tags) to create page layouts
However, not all browsers are that advanced. With css layout horizontal alignment is problemetic.
Also, placing page footers in the right place becomes difficult.
A good way is, try css first. If you face problems use tables for the outer layout and for internal layout (under the table) never use tables just use css(div). Use table internally only to display tabular data not for layout.
5. Always use both id and name tags. use id tag before name tag.
6. For javascript use Use the Document.getElementById DOM that is compatible in all browsers
7. Always use attributes or set properties in div tag not in the td tag when you use div inside td. But use valign on the td, it does not work with div
Page layout with minimal use of table
| Header | |
| Content | |
8. is deprecated and centering a block in css is difficult. So rather use the following css
div.container {
text-align: center;
}div.text {
margin-left: auto;
margin-right: auto;
text-align: left; /* overrule inheritance */}

Seven Principles for Secure E-Voting #103
The information is taken from: ACM Communications, Vol 52, No-2. Author F. Gerlach, Badden Wurttemberg, Germany
- Proven Security: All protocols and techniques must be mathematically proved to be secure
- Trustworthy Design Responsibility: The E-voting responsibility should be assigned to a highly reliable and trustworthy organization
- Published Source Code: Application source code should be made public
- Vote Verification: All voters should be able to verify their votes afterward
- Voter Accessibility: A full list of voters must be available to all citizens
- Ensure Anonymization: Techniques like onion routing should be used for anonymization
- Expert Oversight: The election system must be handled by experts. For example, experts must be employed to handle DDOS attacks.

Sensor Network Simulation #111
Sensor Network Simulation
<p>Sensorsim, a simulation framework that introduces new models and techniques for the design and analysis of sensor networks is developed [259]. Sensorsim inherits the core features of traditional event driven network simulators as well as builds up new features that include ability to model power usage in sensor nodes [259]. Sensorsim supports hybrid simulation that allows the interaction between real and simulated nodes, new communication protocols and real time user interaction with graphical data display [259].</p> <p>Existing tools for modelling wireless networks focus only on communication problems, do not support modelling power and sensing aspects. [260] presents a set of models and techniques that are embodied in a simulation tool for modelling wireless sensor networks. This models are derived with detail power measurements involving two different types of sensor nodes high end WINS nodes by Rockwell and low end experimental nodes built by the authors [260]. A Description of trade offs associated with adding detail to simulation models is provided [258]. Effects of detail in five case studies of wireless simulations for protocol design is evaluated. Ultimately the researcher must judge which level is included for a given question. However, here two approach is suggested to cope with varying levels of details. When error is not correlated, networking algorithms that are robust to a range of errors are often stressed in similar ways by random error as by detailed models. It suggests visualization techniques that can help pinpoint incorrect details and manage detail overload [258].</p> <h2 class="left">References</h2> [258] J. Heidemann, N. Bulusu, J. Elson, C.

Sensor Network: Network Layer: Addressing Mechanism #111
Network Layer: Addressing Mechanism
<p>An address-free architecture is proposed for use in certain contexts where nodes or data are described by attributes other than addresses. Instead of using statically assigned addresses that are guaranteed to be unique, nodes randomly select probabilistically unique identifiers for each new transaction [110]. Another approach where nodes randomly select probabilistically unique identifiers for each new transaction is proposed [111]. It is shown how this randomized scheme can significantly improve the systems energy efficiency in contexts where that efficiency is paramount, such as energy-constrained wireless sensor networks. Benefits are realized if the typical data size is small compared to the size of an identifier, and the number of transactions seen by an individual node is small compared to the number of nodes that exist in the entire system [111].</p> <h2 class="left">References</h2> [110] J.

Sensor Network Protocols #111
Protocols
<p>An energy scalable protocols for battery-operated micro sensor networks is studied [38]. Protocols for self organization of a wireless sensor network is studied in [37]. Shankar et al. [34] provides a cluster based protocol in which only a small fraction of the nodes make expensive long distance base station transfers [34] Shankar et al. [34] also proposed a tree based protocol. A measurement of energy efficiency shows that cluster based method is better than tree based protocol. Mentionable, [34] studied the algorithms using bio sensors having small but continuous power supply. A physical layer driven approach to designing protocols and algorithms is proposed [35]. The paper introduces the design of physical layer aware protocols, algorithms, and applications that minimize energy consumption of the system. An energy efficient protocol to initialize a sensor node in a WSN is also presented in [35]. Power aware multi access protocol with signalling for adhoc networks is provided in [32].</p> <p>Harsh environment with severe resource constraints includes an application-specific protocol architecture, rather than the traditional layered approach, to obtain the best possible performance [33]. The study [33] develops LEACH (Low-Energy Adaptive Clustering Hierarchy), an architecture for remote micro sensor networks that combines the ideas of energy-efficient cluster-based routing and media access together with application-specific data aggregation to achieve good performance in terms of system lifetime, latency, and application-perceived quality. This approach improves system lifetime by an order of magnitude compared to general-purpose approaches when the node energy is limited [33]. The study [33] also develops an unequal error protection scheme for MPEG-4 compressed video delivery that adapts the level of protection applied to portions of a packet to the degree of importance of the corresponding bits. This approach obtains better application-perceived performance than current approaches for the same amount of transmission bandwidth [33]. These two systems show that application-specific protocol architectures achieve the energy and latency efficiency and error robustness needed for wireless networks [33].</p> <h2 class="left">References</h2> [32] R.S.

Sensor Network: Physical Layer #111
A signal processing method for event detection have been developed with low power, parallel architectures that optimize performance for unique sensor system includements [25]. Signal processing architectures for sensor networks are also provided in [24, 26, 30].
<p>Implementation of a parallel data paths with shared arithmetic elements enabling high throughput at low clock rate [25] is presented. This method has been used to implement a micro sensor spectrum analyzer for a 200 sample/s measurement system [25]. A new object-relational data type is introduced termed as GADT (Gaussian ADT). GADT models physical data as gaussian pdfs [28] and shows that existing ../index structures can be used as fast access methods for GADT data. it also presents a measuretheoretic model of probabilistic data and evaluate GADT in its light [28].</p> <p>A physical layer driven approach to designing protocols and algorithms is proposed [31] first presents a hardware model for the wireless sensor node and then introduces the design of physical layer aware protocols, algorithms, and applications that minimize energy consumption of the system [31]. The approach prescribes methods that can be used at all levels of the hierarchy to take advantage of the underlying hardware [31]. It also shows how to reduce energy consumption of non-ideal hardware through physical layer aware algorithms and protocols [31]. Micro power data converter is discussed in [24]. Digital signal processing systems, weak inversion CMOS RF circuits are also designed in [24]. This RF circuit utilizes low power [24]. Some physical layer principles are presented in [30]. In [27] it is identified the opportunities and challenges for distributed signal processing for sensor networks.</p> <h2 class="left">References</h2> [24] G. Asada, M. Dong, T. S. Lin, F. Newberg, G.

FAQs: Sensor Network: Home Automation: Location Determination Service #111
Why extensible?
This is a sensing service for smart homes that includes a full featured location sensing component, and prototype location storage and interoperability components. It also explains how the prototype components can be extended along with demonstrating how the total system can be extended to provide a real smart home. The location sensing can be extended to a larger space, to three dimension, and also to provide robustness to beacon node failure. Using database techniques the storage component can be extended, perhaps XML based database techniques will be helpful. Using Data mining techniques on the database, rules about user habits can be derived. AI techniques might help to monitor and find rules regarding user habits, adapt the system automatically to user habits change. So the system is extensible
What is a home network?
A home area network is a network that connects home computers into a network through wired or wireless interfaces. This network can also include network printers, scanners, or other smart household devices. Also a sensor network integrated with the computer network can also be treated as part of the home network.
In other words, a home area network can be defined as a network deployed in a home to connect the digital devices in the home such as computers, computer peripheral devices, telephones, VCRs, Televisions, Fax Machines, Home Security System, smart" appliances
What do you mean by Pervasive computing
Pervasive computing are the technologies that makes information available to everywhere. Examples are wireless networks, cellular phone technologies. Computing environment using mobile phone, hand-held computers, and smart jackets are parts of pervasive computing to make information available and easily accessible. Therefore, pervasive computing refers to the distributed tools in our environment, through which we access information anytime, anywhere.
What do you mean by Ubiquitous computing
Ubiquitous computing hopes to provide intelligence into the environment. Ubiquitous computing targets to embed computing into the environment where computing will be done automatically to facilitate user activities or will perform actions automatically. Users will be able to interact with computing technologies more naturally than they do now even while moving. Ubiquitous computing would include information everywhere where Pervasive computing would make information available everywhere
ubiquitous computing is best considered as the underlying framework, the embedded systems, networks and displays which are invisible and everywhere, allowing us to 'plug-and-play' devices and tools. Such systems are so embedded and natural that we use them without thinking - except of course when they break down!
What do you mean by context-aware computing?
Context-aware computing aims to use the surrounding environment and user contexts to automate computing and activities to improve user experiences; where context refers to the physical or social situations or states
What is a sensor network?
[From Wikipedia]"A sensor network is a computer network of many, spatially distributed devices using sensors to monitor conditions at different locations, such as temperature, sound, vibration, pressure, motion or pollutants. Usually these devices are small and inexpensive, so that they can be produced and deployed in large numbers, and so their resources in terms of energy, memory, computational speed and bandwidth are severely constrained. Each device is equipped with a radio transceiver, a small microcontroller, and an energy source, usually a battery. The devices use each other to transport data to a monitoring computer.Sensor networks involve three areas: sensing, communications, and computation (hardware, software, algorithms). Very useful technologies are wireless database technology such as queries, used in a wireless sensor network, and network technology to communicate with other sensors, especially multihop routing protocols. For example, ZigBee is a wireless protocol used by Motorola in home control systems."[wikipedia]
What is a wireless sensor network?
"A wireless sensor network (WSN) is a network made of many small sensor nodes (or motes) and one or more base stations (also called sinks), which centralises the data gathered by sensor nodes.Sensor nodes are small computers, extremely basic in terms of their interfaces and their components. They usually only consist of a processing unit with limited computational power and limited memory, sensors (including specific conditioning circuitry), a communication device (usually radio transceivers or alternatively optical), and a power supply. Other possible inclusions are energy harvesting modules, secondary ASICs, and possibly secondary communication devices (RS232, USB...).The base stations are one or more distinguished components of the WSN with much more computational, energy and communication resources. They act as a gateway between sensor nodes and the end user."[wikipedia]
What is trilateration, triangulation, multilateration
Triangulation:[wikipedia]
Trilateration:
Multilateration:Multilateration, also known as hyperbolic positioning, is the process of locating an object by accurately computing the time difference of arrival (TDOA) of a signal emitted from the object to three or more receivers. It also refers to the case of locating a receiver by measuring the TDOA of a signal transmitted from three or more synchronised transmitters.
Multilateration should not be confused with trilateration, which uses absolute measurements of time-of-arrival from three or more sites.[wikipedia]
E-OTD (phonescoop.com)
E-OTD: Enhanced Observed Time Difference:A position-location method for GSM networks in which the phone measures the difference in the time of arrival signals from different towers. Essentially, the phone triangulates its position using signals from the towers, the reports the position back to the network.
E-OTD is one of several technologies that carriers can deploy to meet E-911 includements.
Unlike competing U-TDOA technology, the phone actively participates in the location process. Therefore, E-OTD only works with phones that specifically include E-OTD technology.

What kinds of challenges might arise when deployed in real homes?
- May be more rooms partitions, furnitures more multipath effect
- Noise from radio, TV, VCR, electromagnetic noise
- More people, more movement
- Sometimes party situation
- Location accuracy might degrade
- Home users might not like the phase of data-collection (the number also the time included should be less). May be we can make it application specific.
- Room orientation, furniture movement might happen
- Privacy
How to solve the issues?
- Varying the parameters to find a suitable position
- Use different algorithm like kth nearest signatures can be used
- Can try distributed approach where beacon nodes will calculate the positions
- Beacon nodes can keep only the nearby reference points
- Whatever I found when gets strongest signal from nearest beacon node location is very accurate nearly 1 meter. When we collect data we can place one node at one room. turn off others
- To reduce ref point collection we can first collect data for some points and try to produce data for other positions. May be using an analytical model might improve the situation.
- May be floorplans, furniture positions can be collected in advance so that properties can be collected
- May be a software that will study different models and find the most suitable one
How to extend the system for larger space?
- More beacon nodes
- More base station
- More HGDs interconnected
- May be decentralized system
- Beacon nodes will calculate the positions
- While collecting reference data also collect z coordiates
Why not Ultra wide band technologies?
Well that can be a significat use. Because the signal has built in multipath resistance, low power consumption, security built in. Sensor networks utilizing Ultra wideband technologies can be a good choice.
Many sensor networks using ultra wideband are utilized in health and civil engineering applications. Also, I saw an outdoor location determination project that target to provide centimeter level accuracy in 1 km range.
With UWB, analytical model can also be useful
Limitations of UWB
- Useful in short range, high data rate, robust, low power communications
- Low power pulses can be significantly degraded by channel noise, inter node interference, and intentional jamming

Ubiquitous and Pervasive Computing
Pervasive computing makes information available everywhere. Computing environment using mobile phone, hand-held computers, and smart jackets are parts of pervasive computing to make information available and easily accessible. Therefore, pervasive computing refers to the distributed tools in our environment, through which we access information anytime, anywhere.
Ubiquitous computing would include information everywhere where Pervasive computing would make information available everywhere
Links that describe and provide differences between Ubiquitous and Pervasive Computing
Below are paragraphs that demonstrate the terms clearly as provided in Future A Lab Website. Republished here with their permission.
"ubiquitous computing is best considered as the underlying framework, the embedded systems, networks and displays which are invisible and everywhere, allowing us to 'plug-and-play' devices and tools. Such systems are so embedded and natural that we use them without thinking - except of course when they break down!
Pervasive computing, on the other hand, would be all the physical parts of your life; your mobile phone, hand-held computer or your smart jacket, which changes with your body temperature. Pervasive computing therefore refers to the distributed set of tools within our environment, through which we access information anytime, anywhere."To some extent ubiquitous computing is the attempt to reduce the need to have an overabundance of physical pervasive devices. Rather, its 'grand vision' is to have intelligence built into the things we already use - bikes, cars, toys, fridges and so forth. We are slowly seeing evidence of this within everyday contexts - cars with inbuilt navigation systems, fridges that tell us when we are out of milk or that our food has defrosted.
As a result ubiquitous and pervasive computing are two sides of the same coin. Where ubiquitous computing would include information everywhere, pervasive computing would make information available everywhere. Consequently they share some of the same key goals - the need for useable interfaces, connected via sustainable and scalable distributed networks, where the information is reliable, protected and shared. Key areas of research focus on the development of context-aware and adaptive intelligent systems, devices and networks, which are user-friendly, heterogeneous, flexible and secure.
