Email alert on rootSSh login
Posted: Mon Dec 14, 2009 1:32 pmDo you wanna know who is logging into your server as root??? Use following script and keep record of root login details. I would recommend that you use an email address not hosted on the server your sending the alert from.
So lets get started!
1. Login to your server and su to root, I know the irony!
2. cd /root
3. vi .bashrc
4. Scroll to the end of the file then add the following:
echo 'ALERT - Root Shell Access (YourserverName) on:' `date` `who` | mail -s "Alert: Root Access from `who | cut -d'(' -f2 | cut -d')' -f1`" you@yourdomain.com
Replace YourServerName with the handle for your actual server
Replace you@yourdomain.com with your actual email address
5. save the file
Note: This is a great tool for servers that have multiple admins or if you give someone SSH access for whatever reason, although you should give out the root password to as few people as humanly possible and be sure to change it often.
