Gaia and SPLAT shell/ssh timout values

versions: Tested for SPLAT R75.30 & Gaia R75 & R77.10

the shell timeout for ssh session is controlled by an environment variable called TMOUT. it is a ridiculously annoyingly low 180 seconds / 3 minutes by default for many check point platforms.

check current timeout value

[Expert@myfirewall:0]# echo $TMOUT
600

to change it, use cpshell with account that has root privelege access on SPLAT or Gaia, and set the ilde time...

changing timeout value

[Expert@myfirewall]# cpshell

set idle time in minutes

[myfirewall]# idle 15

if you want it to take effect in your current shell... exit cpshell, from the expert prompt...

[Expert@myfirewall]# source /etc/bashrc

--- note, an "Expert" prompt doesn't mean your account has root priveleges.

when running the idle command from cpshell for the first time, it creates the following file:

/etc/cpshell/cpshell.state

this file containes the idle setting

[Expert@myfirewall]# cat /etc/cpshell/cpshell.state | grep idle
idle=15

This file gets parsed by /etc/bashrc when setting up a shell for a newly connected user

shell startup code

The TMOUT value is set by /etc/bashrc. You can alter the global bashrc or configure local ones for user accounts. Rather than change the global bashrc, the examples above utilize cpshell to set it. If you want to change the global bashrc file, below are the snippets of code that control it from a couple of different releases.

example /etc/bashrc from Check Point Gaia R77.10

# SPLAT specific setup
IDLE="`sed -n 's/idle=//p' /etc/cpshell/cpshell.state 2>/dev/null`"
[ -z "$IDLE" ] && IDLE=3
export TMOUT=`expr $IDLE \* 60`

example /etc/bashrc from Check Point SecurePlatform R75.30

# By default, log out the user after three minutes of unattended prompt
export TMOUT=180
export SHELL=/bin/bash

# Take into account idle setting of cpshell, if available
if [ -f /etc/cpshell/cpshell.state ]; then
  idle=`grep idle /etc/cpshell/cpshell.state | sed s/idle=//`
  if [ $idle"UNDEFINED" = "UNDEFINED" ]; then
         idle=3
  fi
  export TMOUT=`expr $idle \* 60`
fi
