How to Access Wordpress from two URLs (IP)

If you have developed a wordpress Site to be configured for internet and Intranet. The following script will let you access the wordpress site from two different IP address or URLs.
The home folder of wordpress contains a wp-config.php file.

Include the following lines into the wp-config.php file

$LAN_PREFIX = '172.16.';
if(substr($_SERVER['REMOTE_ADDR'], 0, strlen($LAN_PREFIX)) == $LAN_PREFIX) {
    define('WP_HOME','
http://172.16.1.10/glug');
    define('WP_SITEURL','http://172.16.1.10/glug');     // The local IP
} else {
    define('WP_HOME','
http://10.21.15.2/glug');
    define('WP_SITEURL','http://10.21.15.2/glug');     // The public IP
}
this will be suitable for those who needs to conserve the bandwidth inside your campus (Use Intranet) and can access outside the campus (Use Internet).

NB: Once this setting is enabled and restart the server, inside the wordpress dashboard-> settings –> General –> The HOME and SITEURL will be blocked (Uneditable).

We have installed TexLive 2019 and texstudio.

To install texstudio

$] sudo apt install texstudio
The look and feel of TexStudio looks like this image.

Implementing a new system call in Kernel version 2.6.32

A system call is used by application or user programs to request service from the operating systems. Since the user programs does not have direct access to the kernel whereas the OS has the direct access. OS can access the hardware through system calls only.The following files has to be modified for implementing a system call/usr/src/linux-2.6.32.5/arch/x86/kernel/syscall_table_32.S/usr/src/linux-2.6.32.5/arch/x86/include/asm/unistd_32.h/usr/src/linux-2.6.32.5/include/linux/syscalls.h/usr/src/linux-2.6.32.5/MakefileNew set of files to be createdCreate a new directory newcall/ inside the path “/usr/src/linux-2.6.32.5/” Create new files Makefile, newcall.c and put them in the /usr/src/linux-2.6.32.5/newcall/ folder Create new user files (in any folder of Linux) to test the system call
