cannot login to ssh

    SSH (is up and runing) is not letting me in.

    I have direct root disabled but the user is in the usergroup and I logged in with user/password fine. I type su -l and it asks for root password of course, typed that and enter...but then nothing happens just breaks a new line and no text.

    su -l
    su -
    su

    all give same error

    I enter a few times and get "bad message".

    example:

    -bash-2.05b$ su -
    Password:





    bad message
    -bash-2.05b$

    The space is me pressing enter 3-4 times until I get "bad message".

    How do I fix this?

    Is the user in question in the wheel group?

    It just said usergroup so I thought Id ask exactly :)
    What shows up in your logs? Surely there'd be an event regarding failed logins..

    /var/log/messages = empty

    That is all I know for now. I'm stuck at bash prompt and cannot get into root.

    Shouldn't be empty at all.. Re-enable root login, get back in as root, and see if you can find out what went wrong.

    I think the whole point of my thread is that I cannot get into root in the first place :)

    I never disabled root either. I stated both these in my first post. Please read again at it.

    I disabled "direct" root login. That does not affect anything. Someone just decided to install webmin and screwed up the login process somehow, so I'm stuck between a rock and a hard place

    Go on, have a guess
    What do you mean by that?

    If you didn't install webmin and don't know who did, your /var/log/messages is empty and your having problems su into root, then it sounds like your server has suffered a root compromise.

    I never said I didn't know who installed webmin, my customer did but he obviously did something wrong to affect root login

    Then your only realistic option to to fix it from the servers console where you can login as root. If you don't have access to the server console or your NOC doesn't offer console support, then you're most likely going to have to OS reload the server and restore your backups.
