Apparent logoff’s due to inactivity.
I have run across an issue with the last two Dell Poweredge servers I have attempted to deploy. I seems that when a telnet session sits idle for 5 to 30 minutes (seems random) the session is being closed and users are logged off. If the session has user activity there is no problem staying connected. I know it sounds like an inactivity timer but the odd thing is that this does not happen when connected via a local switch or crossover cable only through a router plus the idle out time is not consistent. VPN or straight telnet have the same result. I have flashed the router twice. Replaced the router. Installed an out board intel pro 100 nic (which is native to SCO). Locked the nic into 100mb fdx & adjusted the mtu from 1500 to 1300 ( per sonicwall tech support). Flown 1500 miles to do a bare metal re-installation of the OS. Replaced the machine. Remove all of the routers from the loop and connected the server direct to the internet. Moved the whole setup to a new facility on a different backbone in a different city. Still the issue remains. The kicker is that if I put a humble Power Edge 1800 non raid system on 5.0.7 MP4 with onboard Intel pro / 1000's it stays connected just fine. Has anyone else seen this odd behavior with this class of server or OS version?
The current configuration is:
Server:
Dell poweredge 2800 raid 5 perc 4/di ( amird )
Dual Procs, 8 gb ram
Dual integrated Intel Pro / 1000 using driver version 5.0.7f
SCO 5.0.7 MP5 (Updated from MP4)
Previous configuration:
Dell poweredge 6800 raid 5 perc 4/di ( amird )
Dual Procs, 8 gb ram
Dual integrated Broadcom BCM57xx / 1000 using driver version 9.4.1
SCO 5.0.7 MP4
Router:
Sonicwall 4060 on OS 3.2 enhanced
Alternate router used in trouble shooting process:
Sonicwall 3060 on OS 3.2 enhanced

NAME
sb2-session - manage scratchbox2 sessions
SYNOPSIS
sb2-session [COMMAND [PARAMS]]
DESCRIPTION
sb2-session is used to create attachable scratchbox2 sessions. You can save session even when you haven't done '-S session' during sb2
startup.
Note that you can give parameters to attach command which are passed verbatim to sb2. If there is only one session to attach, it is
selected automatically.
If no command is given, help text is printed.
COMMANDS
help shows help text
save saves current session
list lists detached sb2 sessions
delete SESSION
deletes given session
attach [SESSION [PARAMS]]
attaches to a given session
setenv VARIABLE VALUE
store a value for an environment variable
showenv
show stored environment variables
EXAMPLES
Basic usage is:
[SB2 .. ] $ sb2-session save # save session
[SB2 .. ] $ ^D # exit
Later we can then attach to this session:
% sb2-session attach
If there are more than one saved session, then:
% sb2-session list
session.XXXX TARGET_ARM My Comment
session.YYYY TARGET_ARM My Comment 2
session.ZZZZ TARGET_MIPS
% sb2-session attach session.YYYY
Here we pass '-eR' to sb2 and we only have one saved session:
% sb2-session attach -- -eR
'--' marks end of parameter list for sb2-session.
setenv VARIABLE VALUE can be used to add environment variables, that will become active when a saved session is later taken into use
(either by sb2-session attach or by sb2 -J).
setenv VARIABLE VALUE does not change environment of sessions that are already active.
showenv lists environment variable settings which have been stored with this tool. It does not show environment variables from other
sources.
