    I have 4 servers. 2 with cPanel 2 without.


    Anytime I SSH into any of my cPanel servers, the "last" or "who" commands just shows the connecting IP address no hostnames. If I SSH into my non-cPanel servers, the "last" and "who" commands shows the connecting hostname instead of the IP address.


    What could be causing the cPanel servers to not show the hostname? Is there a setting that I need to change on the cPanel servers to enable this somehow?

    Ive noticed this happening before. I never thought much about it as I have all named connections in PuTTy but im curious as to what others think about this.

    This is because your /etc/ssh/sshd_config contains the entry of "UseDNS no" which allows brute force detection I believe.
