Check /etc/pam.d/sshd and see what's being loaded. Then, look for the

This is not an SSH support list. SSH uses OpenSSL libraries, but
that's the extent of it.
My conjecture (and this is only my conjecture): you may be running TCP
wrappers, or you may have host-based access blocking disabled. In any
case, it's at least used for logging purposes (since names are ea

When sshd has received the username of a linux user from a SSH client, it

on 192.168.56.1, this machine will send a PTR request on
105.56.168.192.in-addr.arpa jus
