How to logout sshd after x hour idle

[robertlouwen]

Hello all,

At this moment I login to sshd with putty and stay logged in forever. Example: I log in at 23:00 and go to bed, the next morning ( after 8 hours inactivity ) I am still logged in.

I want to change this behaviour ! After, for example, 1 hour inactivity you get logged out.

How do I do this ?

Try setting the environment variable TMOUT=3600.

Hello BorderAmigos

In my sshd.config is no TMOUT variable, can I just add it ?
and 3600 is in seconds, isnt it ?

Have a good weekend

No, not in sshd.config. It's an environment variable. Try putting this in /etc/rc.local or /etc/profile

export TMOUT=3600

Yes it's in seconds. Googld TMOUT for more info. I haven't actually done this so don't guarantee 100% it will work for you.


or

ClientAliveInterval 3600
ClientAliveCountMax 0

in /etc/ssh/sshd_config.
