intermittent lost connection

Rosli Ahmad — Sun, 21 Sep 2003 23:24:29 GMT

Hi,
My HP9000 is disconnecting my telnet session intermittently. I am wondering where should I start in troubleshooting this issue. Does anyone ever encountered the same problem before? Thank you.

I will check error logs on switch/router/firewall to start with.
Try telnetting from different subnets and compair the results.

I have been through the same time and problem were found either with router which was dropping the frames or with wan link.

Hi Rosli

Are you sure the TMOUT variable is not set?
Check with:
# echo $TMOUT

Also check a timeout has not been set on the firewall/switch for telnet sessions.

You could also check /var/adm/syslog/syslog.log & see if there is any messages.

Cheers
Con
