For security reasons, you would like to get an alert to your mailbox if someone logins to the server with root credentials.
Step 1. Make sure csf firewall is enabled on the server.
Step 2. Check CSF configuration file .
Make sure below values are set to 1 -
LF_SSH_EMAIL_ALERT = "1"
step 3. Add your email address on which you would like to receive an email your@yourdomain.com -
LF_ALERT_TO = "your@yourdomain.com"
Step 4. Restart firewall.
csf -r
Alternatively, make sure following parameter is enabled in csf -
LF_CPANEL_ALERT = "1"
You can then go ahead an add following code to bashrc file -
cd /root
nano .bashrc
echo 'ALERT - Root Shell Access (ServerName) on:' `date` `who` | mail -s "Alert: Root Access from `who | cut -d'(' -f2 | cut -d')' -f1`" your@yourdomain.com
Replace your@yourdomain.com with your email address.
That's it!
