How to set up daily email alerts for chkrootkit?

Login to your server as root and at the root prompt fire the below command:

root@xxx[~]vi /etc/cron.daily/chkrootkit.sh

Insert the following to the new file:

#!/bin/bash
cd /your_installpath/chkrootkit-0.42b/
./chkrootkit | mail -s “Daily chkrootkit from Servername” admin@youremail.com

==========
Note
1. Replace ‘your_installpath’ with the actual path to where you unpacked Chkrootkit.

2. Change ‘Servername’ to the server which you are running.

3. Change ‘admin@youremail.com’ to your actual email address where the script will mail you.
==========

Save the file.

Change the file permissions
root@xxx[~]chmod 755 /etc/cron.daily/chkrootkit.sh

Now if you like ,you can run a test report manually in SSH, to see how it looks.

root@xxx[~]cd /etc/cron.daily/
root@xxx[~]./chkrootkit.sh

You’ll now receive a alert with the report!

Everyday you should receive the alert.

You don’t have to run it manually.
