* ssh -X user@host konsole opens a tunneled konsole, but then the tunnel lapses

CygWinners:
For years I have enjoyed one desktop with everything I need on it.
Then ssh -X stopped working. Sometimes, if I start a remote konsole,
and immediately start some new X window app, it runs thru the tunnel.
But now it trivially bombs, as if there were no remote X to attach to:
kate: cannot connect to X server localhost:10.0
Is there a timeout setting, somewhere, for the X tunnel? or some
similar setting to look at?
The host is any Win32 or Win64, and the client is Ubuntu...
I also tried manually setting the DISPLAY environmental variable...

Bump?
Should I try a noisier forum, or one for a different layer of the system?

Have you tried ssh -Y instead of -X ?

Nope; just tried it, and it didn't work, with the same symptom.
The source is always a CygWin xterm with a little bash inside.
Got a log file I can look at?

You don't mention if things 'stopped working' spontaneously, or if anything
was changed on either your ssh client or ssh server machine.

There is the ForwardX11Timeout setting (see 'man ssh_config'), but that can't
be the explanation for what you are seeing, as that doesn't apply with 'ssh -Y'

If you are saying that it doesn't work from any cygwin machine, connecting to
one particular ubuntu server, that should be a pointer that something has
changed on the ubuntu server.

If you are setting DISPLAY to point directly at your Cygwin/X server, you will
need to permit access from the remote host, as described in the 'insecure
telnet' section of [1]. Protip: don't do this, it's insecure :-)

You might find adding '-v' to your ssh command for extra verbosity sheds some
light on what's going on.

I think you have that backwards.

^^^^ See this URL.
You didn't attach cygcheck output, so no one knows what version of anything
you are running, so all this advice is purely speculative.

Tx guys - either the -v or the -Y did it.
(Yes yes I know -v is just the debugging trace. Maybe it changes the timing!)
