Unable to connect via SSH

    Hello all,

    I am trying to connect to one of my servers in a data centre via SSH, but as of this morning I seem unable to. Can anyone explain to me where the problem may be, based on the output below from the client.

    The client hangs for a few minutes after 'debug1: SSH2_MSG_KEXINIT sent', before the connection being closed. This happens from all my machines so I'm assuming it's not a problem with the client.

    The client is a Ubuntu 6.06 box and the server is Mac OS X 10.3 (pretending to be a UNIX box).

    neil@ubuntu:~$ ssh -vvv [email protected]
    OpenSSH_4.2p1 Debian-7ubuntu3, OpenSSL 0.9.8a 11 Oct 2005
    debug1: Reading configuration data /etc/ssh/ssh_config

    Any help would be much appreciated as I'm unable to connect to the server via any other method.

    Thanks
    Neil

    I don't see any errors in the output.
    Maybe you should reset the system and try a new login after it has come up again? If that doesn't help - do you have a rescue system on the server that you can boot into to repair the system (and to scan it for malware/rootkits/trojans...)?
