Timed out

Timed out

[Mark Koenen]

Hi,

When I don't use my Z-shell on a remote computer for a while, I get
disconnected (after about 15 minutes):

   markko @ kunhp1>Read from remote host kunhp1.cogsci.kun.nl: Connection reset by peer
   Connection to kunhp1.cogsci.kun.nl closed.


In ~/.zshrc I have:

   TMOUT=0

I use zsh-3.0.5. Anyone knows how to avoid this little nasty thing?

Thanx in advance,
Mark.

That's not a zsh timeout logout.  You would have seen this if TMOUT was
the culprit:

  markko @ kunhp1>
  zsh: timeout
  Connection to kunhp1.cogsci.kun.nl closed.

You might want to try tracing the zsh process from another telnet
session (with truss/ktrace/trace/strace) and see exactly what happens
when the connection is dropped.

Maybe is the problem with history reverse search and terminal interrupt
which 3.0.5 has.

There were several suggestions for a possible source of the problem:
 - It could be an idle timeout set on the remote computer
 - Try setting
     TRAPALRM() { print "Someone sent me an alarm signal"; }
 -  try tracing the zsh process from another telnet session

Nothing helped until a friend suggested it would be the firewall
that I'm using that causes the problem. Indeed it did :-) The
firewall (I use IPCHAINS) closses connections when they're not
used for a while; a TCP connection will be closed after 15
minutes... To increase the timeout time call IPCHAINS with the
-S option. A piece of my  rc.firewall :

   # The default masquerading timeout is 15 minutes. This can be used
   # to set it to higher values.
   $IPCHAINS -M -S 7200 10 900

This sets the timeout to 2 hours; long enough to go to the toilet,
do the dishes, have a chat with the neighbour and returning to your
computer without having to login again... ;-)

Thanx for all the suggestions!

Mark.

It could be an idle timeout set on the remote computer; have you checked with 
the sysadmin of the remote machine if this is the case?

Yes, I checked, but he doesn't know of anything. When I use bash I don't
have the problem... The problem occurs on each different network (work,
university, provider) I can logon to. I use almost identical .zshrc's
in the different environments.

Try setting
  TRAPALRM() { print "Someone sent me an alarm signal"; }
which should at least tell you if the the shell thinks it's getting a
timeout (and stop it).  This is the mechanism that TMOUT uses:  if it goes
on merrily as before, it must be something else.
