Even if root login is allowed in it's configuration but pam disallow root logins, it'll result in a 2 seconds delay on bad password and reject instantly good password instead of login. The problem is not in the handling of PermitRootLogin but in the handling of login in sshd, adding a 2 seconds delay before login or removing the 2 seconds delay on bad login before sending an error would fix the problem. > $ ssh root@host > root@host's password: <- arbitrary (non-null) string > [2 secs delay] > Permission denied, please try again.a > > $ ssh root@host > root@host's password: <- correct root password > [no delay] > Permission denied, please try again. > > i haven't checked the current version to see if this is still true. I verified this on redhat 8, openssh-3.4p1-2(rpm) and sshd is acting just like you described it.
