Re: [LINUX5250] Timeouts

["Dennis Lovelady" <dlovelady@xxxxxxxx>]

Sorry, Brendan; right you are!

In fact, your suggestion was one that seems to have identified the problem.
My apologies.  It does sound like the same issue, though.  What IS your
CHGTELNA  TIMMRKTIMO() set to?

I can tell you that by default on most platforms, telnet *client* does not
time out.  What platform are you using?  Can you give a better indication
of how long it is before the timeout occurs?  What messages are in QSYSOPR
message queue, and in your own joblog when the disconnect takes place?

It is also possible that the network (firewalls, gateways, routers) at your
location is tripping you up.  If you have a network administrator and any
of those devices, you might want to run this question by them.

If you're on linux, you can run tcpdump or other capture utility to see
what the activity between the client and the host is at the time of
disconnect.

HTH

Thanks but I already looked (and offered an answer)... but the problem is
on
the PC... somehow the xt5250 windows closes after I press Enter but before
it
contacts the host... I can tell this because it's a connect-on-demand
connection and it didn't connect.
