Unable to connect via SSH
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 firstname.lastname@example.org
OpenSSH_4.2p1 Debian-7ubuntu3, OpenSSL 0.9.8a 11 Oct 2005

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