I have a problem with SSH. I can connect from my computer at home, but at school, when I try to connect using one of our 10.5 iMacs, I get
ssh -2 -vvv email@example.com
OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006
debug1: Reading configuration data /etc/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to greenlantern.dreamhost.com [220.127.116.11] port 22.
debug1: connect to address 18.104.22.168 port 22: Connection refused
ssh: connect to host greenlantern.dreamhost.com port 22: Connection refused
Why does this happen? It only happens at school. There is no firewall, because if I try to connect to my SSH server at home, I can.
