My apologies if this is a FAQ - I have been RTFMing
for two days now and haven't been able to find an
I have a machine running RH 9 with kernel 2.4.20-31.9
and openssh 3.9p1/openssl 0.9.7e. sshd is on port 22,
and there is a Linksys router forwarding port 22 to
the RH box, which is on a home LAN.
I have a laptop which can boot into either Windows XP
or Debian. In both cases the network configuration is
the same (static IP). When it boots into Debian, it
can ssh to the router's external address and connect
to the RH machine. However, when it boots into Windows
XP, it can't connect with ssh (I tried Cygwin, Putty,
and WinSCP) via the router's address; in all cases the
client times out. When I telnet to port 22 on the
router, I get nothing until I type some random
characters and hit enter a couple of times, at which
point I get the SSH version number.
Connecting using the RH machine's LAN address works
fine in all cases.
Connecting from a remote Linux machine which is not on
the local LAN, I can SSH in properly, and telnetting
to port 22 immediately shows the version number.
Connecting from a remote Windows machine which is not
on the local LAN shows the exact same behavior as when
I connect from a local Windows machine, i.e. it
In summary: ssh/telnet/putty/winscp from Windows to
the router always times out, ssh/telnet from Linux to
the router always succeeds. So it appears to be a
Windows/Linux problem rather than a local/remote
Here's the funny part: this problem first appeared
when I installed a new a 3c2000 gigabit ethernet card.
Using my old 10 megabit 3c900 card makes this whole
problem go away.
Thanks in advance.
