Receive Root login alert on your email id

[George]

If you would like to receive mail alert after any one logn into your server as root user then follow the following steps.

First login into server as root and open the file .bash_profile in your favorite editor and then add the following line in the end of the file .bash_profile

vi .bash_profile

echo 'ALERT - Root Shell Access on:' `date` `who` | mail -s "Alert: Root Access from `who | awk '{print $6}'`" your@email.com

You will receive mail at your@email.com with all information like ip address,login time etc.

Thanks George,
It's really very helpful to enhance the security of the servers especially web server which exposes to the Internet and worldwide hackers, it is best to enable server to automatically send a notification email to predefined email address everytime someone logs in as root to the host.
