More info: We've checked firewall logs, and it seems to be a firewall rule designed to prevent sessions which are subject to the bug detailed at < http://archives.neohapsis.com/archives/bugtraq/2002-06/0294.html>. I've tried explicitly setting PAMAuthenticationViaKBDInt no, KbdInteractiveAuthentication no and UsePrivilegeSeparation yes in sshd_config, but the problem still occurs, so I think the firewall rule is buggy. So, doesn't seem to be an OpenSSH problem per se, but I'll follow up with anything more I discover in case other people encounter the issue -- it's possible that the rule in question is deployed quite widely. mathew _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
