Hi, So I've been using SSH for years, and am very familiar with it. Right now I want to setup my iMac so I can SSH into it from my computer at work, as I work on stuff at home and at work and SSH is simply the easiest way for me to access everything I need (files, applications, etc). So, I have a number of questions: After selecting enable remote login, etc (as I have done in the past and had it working) I then try to SSH into my iMac from a different computer on the same network. SSHing using verbose mode produces the following output: Last login: Wed Dec 31 19:00:26 on console Welcome to Darwin! dyn-209-2-234-56:~ marshall$ ssh -vvv XXXXXX@dyn-river-XXX-245.dyn.columbia.edu OpenSSH_4.5p1, OpenSSL 0.9.7l 28 Sep 2006 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to dyn-river-XXX-245.dyn.columbia.edu [160.39.XXX.245] port 22. debug1: Connection established. debug1: identity file /Users/marshall/.ssh/identity type -1 debug1: identity file /Users/marshall/.ssh/id_rsa type -1 debug1: identity file /Users/marshall/.ssh/id_dsa type -1 ssh_exchange_identification: Connection closed by remote host dyn-209-2-234-56:~ marshall$ ? Does anyone have a clue as to why I might be unable to SSH into my iMac? I know that port 22 is clear and open not only on my iMac but on the network as well (no network blocks on port 22). Also, I can SSH from my iMac into the other computer but not into my iMac. This was particularly frustrating because I recently went on a trip and needed access to my iMac... I had turned on SSH before I left but oops! Couldn't use it... Is there a ssh preference file on my iMac somewhere that I need to fix?
