Got new router, can't ssh in now
I'm running Mandrake 10.0, and I've got sshd running. I used to connect to the net through our XP machine, but we recently bought a D-Link DI-604 router. I can still get online no problem (typing this now from the Mandrake box).
Before, I used to ssh in from work/school. I had hosts.allow set to let my work machine or the school domain name in, but nothing else (except the LAN). No problem, just ssh user@<dynamic IP>, and I was in (I also set sshd to only allow me as a user).
Since we got the router, I cannot ssh in to my Mandrake box. I have changed everything on the router that is suggested (Virtual Server SSH points port 22 to my Linux machine running sshd), and the router's log never mentions my attempts to ssh in, so I'm guessing it's not stopped there. I've tried other ports in case work/school started blocking 22, too. I can still ssh in from the XP machine on the LAN, so I know that sshd is up and running.
Does anyone have any suggestions? How can I find out if the Linux box is rejecting my attempts? Is there some log file I can look in? Do I need to set sshd to log more?
Any help would be appreciated -- I've googled and checked a few books, but to no avail. It would help if I had some kind of error message to look at, but there's just an eventual timeout.
