I began seeing this same behavior on a RedHat 7.2 system, after installing
openssh-3.1p1-8. The ssh connection and login is successful, and produces this
output in /var/log/messages:
Jul 30 13:12:48 themachine sshd(pam_unix)[1856]: authentication failure;
logname= uid=0 euid=0 tty=NODEVssh ruser= rhost=somewhere user=someone
Jul 30 13:12:52 themachine sshd(pam_unix)[1856]: session opened for user someone
by (uid=0)
Jul 30 13:12:52 themachine sshd(pam_unix)[1856]: session closed for user someone
This is with kernel 2.4.20-19.7.
The /etc/ssh/sshd_config file had been changed as follows:
X11Forwarding yes
PasswordAuthentication yes
ChallengeResponseAuthentication no
PAMAuthenticationViaKbdInt no
This is a problem, because the /var/log/messages file has tons of false alarms,
and they will obscure any real failed login attempts.
FYI, this was already reported in Bug #101157. I'm experiencing the same problem under both RH 7.3 as well as 8.0 after updating all openssh packages to 3.1p1-8. FWIW I built openssh-3.6.1p2-1 from the src rpm from openssh.org and do not experience the delay in a valid login or bogus auth. failed messages. The delay is bad enough for us since we uss ssh to run all sorts of commands remotely on a growing likst of machines and 2 seconds adds up. but bogus error messages regarding something as werious as authentication is absolutely unacceptable IMNSHO. Natlin - please do not close this with NOTABUG as you did 101157. There is something seriouly wrong with the back port unless I am serioulsy missing something which is entirely possible. Red Hat may do something that is difficult to incorporate but this need fixing or you will have a lot of users backing this out.
