  1. Create a alert on my server such that if anyone other than my and my manager IP’s login to the server we should get an mail based alert with the user ID & ip address.

    Please help.

  2. Hi, I just tested this on my Linux box and it works well. However, if i need to reverse the script, how do i achieve that?

    echo ‘ALERT – Root Shell Access (ServerName) on:’ `date` `who` | mail -s “Alert: Root Access from `who | cut -d'(‘ -f2 | cut -d’)’ -f1`” [email protected]

  3. Hello!

    I get this when attempting to install mailx the above command.

    Reading package lists ... Done
    Building the dependency tree
    Reading status information ... Done
    The mailx package is a virtual package provided by:
      mailutils 1: 3.1.1-1
      bsd-mailx 8.1.2-0.20160123cvs-4
    You must explicitly select a package to install.
    
    E: The "mailx" package does not have a version that can be installed
    

    As the message says, apt-get install mailutils works.

    Thank you for sharing your knowledge.
