Strange SSH disconnect problem

[Rene Caspari <liste dot cygwin at ahrcas dot net>]

Hello,

I have a strange problem using openssh (client) with cygwin and
Windows7. After starting Windows I start a SSH connection from within
mintty and bash to Server A, afterwards Server B, C and so on.
If the SSH to B and C is idle for some time, the connection is
interrupted and after a few seconds closed, but only for B and C, to
Server A it still works fine.

Another strange thing, if I open SSH to Server A at first and after it
another connection to Server A, the second connection have the same
disconnect problem, the first works fine again...

I tried it with and without TCPKeepAlive, nothing changed, there is no
desktop firewall or something and other connections (jabber, rdesktop)
are fine.

I'm using ssh-agent with keychain but I can't imagine why this can be
problem.

Do you know this behavior or have any idea?


Kind regards,
Rene
