Hi all, thanks for the suggestions so far. I talked local staff through backing up the sshd configuration file, purging the openssh-server package and then reinstalling openssh.
I'm quite frustrated to say this didn't fix anything. Had exactly the same behaviour: <snip> debug1: Next authentication method: keyboard-interactive debug2: userauth_kbdint debug2: we sent a keyboard-interactive packet, wait for reply debug1: Authentications that can continue: publickey,keyboard-interactive debug3: userauth_kbdint: disable: no info_req_seen debug2: we did not send a packet, disable method debug1: No more authentication methods to try. Permission denied (publickey,keyboard-interactive). I did two further tests: 1. ssh from the box itself to localhost: Same result, permission was denied, no info_req_seen 2. tail -f /var/log/auth.log on the server - staff reported no new entries while I was attempting to login Does this mean that we never get to the authentication mechanism? I'm quite clueless now, I too was expecting that a purge and reinstall would fix it. -A -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
