ssh reliability problems

tunneling X traffic over ssh seems to fail at the four to six hour mark. 
  all the connections shutdown with little reported information.  Normal 
ssh sessions stay running fine.

yes, I am using the -Y option is recommended in the FAQ.  I am using a 
reasonably current (as of last week) copy of openssh via cygwin.

ideas?

autossh might help.  It starts ssh sessions and periodically checks them to
make sure that they're still passing data-- if they're not, it terminates
them and starts a new one.  This is often helpful, but maybe not in your
case, since you say that other tunnels are still good after the X tunnels
fail.  I don't know what would cause that.

Good luck,
Andrew.

Thanks a lot, now it's working.

Is the -from switch documented somewhere? I couldn't find it either in
the manpage or in the example bat script.

Just try. There may always be small problems but a lot of program work
out of the box now.

Re: Re: xmove compilation for cygwin

It  worked out of the box when I tried a couple of years ago. Use xmkmf to generate a make file (from the imake
file) then just run make.

Re: Re: xmove compilation for cygwin

Cool, I have got first obstacle in the process -- there is no
Imake.tmpl, or as xmkmf reports it:
imake -DUseInstalled -I/usr/X11R6/lib/X11/config
Imakefile.c:9: Imake.tmpl: No such file or directory
imake: Exit code 1.
  Stop.
and ,indeed, it is neither present in the /usr/X11R6/lib/X11/config
nor in any other directory. Where can I download Imake.tmpl
specific to Cygwin? I  remember that I have posted the e-mail
with almost the same question (about Imake.tmpl) but I did not
get any responses or I do not remember getting them ;-)

With Best Regards

thanks.  I may try that.  Another data point.  Tunneling sessions using 
putty don't die.  It seems to be only OpenSSH tunnels that have problems.
