SSH error message

[lingsongyou]

Hey guys

I am trying to SSH into a computer where I work, and I always get the message "ssh_exchange_identification: Connection closed by remote host"
when I do either
"ssh -l mberger patdsk2.fnal.gov"
or
"ssh mberger@patdks2.fnal.gov"

I am told by the tech people that this should work, but I always get this message. I would appreciate any help anyone could give me

Make sure you have an ssh server running on the remote machine. That's where I've seen this error before. On the remote machine, you can find out if the ssh server is running with ps -ef | grep sshd
