ssh issues

Hi,
for some unknown reason, i can no longer ssh to may machine from the
WAN. i do not believe anything has changed (ok, obviously something i
don't know about has changed...but not that i am aware of). here's
what i know

-my Windows XP box's firewall is allowing port 22
-my DLink router is allowing port 22
-sshd is running
-i can ssh to localhost on the box

however if i try to ssh from the WAN, i get an error:
ssh: connect to host 69.119.168.252 port 22: Connection timed out

the only think i can remeber that i did last was change the encryption
from 64bits to 128 bits. i have since changed back to, but his does
not yield better results.

any ideas what may be coming on here?

Use tpcdump and check if packets are coming in the machine, check
the firewall configuration.

Another thing you can do it telnet to port 22. You won't be able to log
in, of course, but you can see if you get any response at all.

as mentioned, i have done some intial diagnostic, and firewall and
router configurations were checked. what do you mean "use tcpdump and
check if packets are coming in". packets are coming in, as i can
recieve data from the web. it has to do something with either SSHD or
something else is blocking port 22. just don't know what...

this is working...with telnet responding with the version of open ssh

Did you check the 'firewall' on your Linux box?

Hi,

What XP firewall?? Again XP firewall.. that already big mistake. Ok to
be frank... try u simple debugging. First ping to linux machine. If can
try telnet to http port [80] on linux machine. If can then try ssh port.
If nope, try stop firewall application on XP and try again. You got ur
answer why.

command will be:

ping linuxmachine
telnet linuxmachine_ip 80
telnet linuxmachine_ip 22

if anything print out on ur DOS shell or console..look good.. its
great.. if return error got problem.
