Hi, I use pam_cracklib and pam google-authenticator in an ubuntu server. and many users log in from the same IP. But when someone makes some login failures for 8-10 times, the SSH gets blocked for a few minutes. All I can see in auth.log is a few PAM authentication failures… I don’t know what is blocking the SSH. But I don’t want that to happen for at least one IP since it causes problems for many users. Any idea on how to fix this?
