Hi
who times you out ?

Do you connect via ssh, then your timeout settings are located in the config-file from sshd daemon

ClientAliveInterval 180
ClientAliveCountMax 20

means 180s*20 = 3600 s = 1 hour

You can only change this settings for all connections and you have to restart the sshd

Hint: if you don't want your session closed you can use
sar 600 600
than your session will keep alive

Hi,

It will take affect at next login, current login just do an # export TMOUT=0.

The value is set each time you login. Any user can change the value after they login by setting it to the new value, or even do it automatically in .profile for each user.

If the system administrator sets TMOUT to readonly as in:

readonly TMOUT
export TMOUT=3600

then not even root can change the value in the local shell. NOTE: root should *always* timeout after a few minutes, no more than an hour, to avoid security problems.
