Problems with SSH using PuTTY
Hi, I've been banging my head against the wall for days trying to connect to my linux computer using Putty. I know it shouldn't be hard, but I can't seem to get the most basic connection sorted. I need to:
-Leave my linux system on at home. It is sitting behind a standard wireless home broadband router.
-Connect to this from work (or anywhere) using a windows XP laptop.
-I can play with cygwin or whatever later, right now I'd be happy with simple terminal non-root access
-The idea is that the home computer is running OpenFOAM CFD and will sit there crunching numbers all day. That way I can just access it from anywhere to set it going, check logs etc.
Whenever I try to connect to the computer using putty from my laptop, it just times out, no connection refused or anything. It just sits there, blank screen for 30 seconds and then says 'Network error: Connection timed out'.
I have tried:
-from inside the home network 'ping 192.168.0.4' (linux desktop) from my laptop. It works
-ping 192.168.0.3 (laptop IP) from the linux machine. It works
-putty to 192.168.0.4 times out
-putty to the router IP (from whatsmyip.com :oops:)and setting up port fowarding also times out. The router is definitely 'seeing' and forwarding on the connection, I can see it in the logs. I set it to forward to 192.168.0.4
-I've tried all of the putty attempts mentioned using port 22 AND ALSO tried with a different port (1557). that includes the putty setting, the port forwarding and the port listing in sshd_config (and before you ask, also restarting sshd after any changes)
-connecting from the same linux computer. ie ssh localhost or ssh -p 1557 localhost. This works fine
Essentially it doesn't seem like my linux computer is 'hearing' the SSH request coming in, or possibly Putty is not sending properly.
Any ideas whats wrong? I'm afraid I'm not very Linux- literate. Is there some way I can narrow down the error by getting the linux computer to 'listen' and see if its getting the SSH request from putty, for instance?
Thanks very much for any help.
Some specific details:
desktop running OpenSUSE 11.2
I have tried setting it up 'vanilla', and alternatively followed the configuration from (EDIT, oh wait it won't let me put URLs in) erm.. the guide here:
I am in the UK, using a Sky broadband router
