SSH: connection refused....but only from a few places. Eh?
Here is a weird one....I have a server set up which accepts SSH connections. This usually works from everywhere, even via 3g mobile networks. However, on a couple of machines it simply says connection refused. Since this isn't usually a problem. what could be blocking it? I have even tried turning off iptables to no effect. hosts.allow/deny are blank and /etc/sshd/sshd_config doesn't have a DenyUser for any of the users that get refused.
