Hi All...

I have seen the same thing between two windows XP machines. Always the firs=
t ssh
connection after a long period of no ssh activity would hang and subsequent=
 ssh
connections would be fine. From my experience the problem was associated wi=
th the
server host, not the client host. I was always running the same Cygwin vers=
ion and
OpenSSH version on both machines when it happened.

It seemed to be more frequent on some (slower? older?) XP laptops. Whenever=
 I had
time to debug it, it worked fine, so I never did more than the tests in thi=
s thread. The
technology to detect that is impressive :-)

After significant use, I have not seen this problem with Cygwin 1.7 (on XP)=
 and I have
not seen this problem with (newer? faster? Vista?) machines.

Thanks,

...Karl
