sshd auto-logout

Hi,

I'm running shhd on the server (FreeBSD 9) and remote users can log on without problems.

Now I want that they get logged out after a certain period of inactivity, say 30 mins.

I tried setting ClientAliveInterval and ClientAliveCountMax in sshd_config, but to no avail.

Code: 
ClientAliveInterval 10
ClientAliveCountMax 3

I restarted sshd(8) (/etc/rc.d/sshd restart).

As I understand it, the above options should log the user out after 30 seconds of inactivity. But they are not logged out at all.

Thanks

NO, you understand it wrong.
Code: 
ClientAliveInterval 10
ClientAliveCountMax 3
SSHd used this settings when it can't talk to a client. (network disruption for example)
This usually need to avoid ghost sessions in case if client loose connection.
BTW, if you talking about 30 min you wrote it wrong, ClientAliveInterval should be specified in seconds(!!!)

Feature that you're looking for - provided by shell( keep in mind that not all of them support this feature ) but SSHD
Read tcsh(1) about autologout for example. /usr/ports/shells/bash use TMOUT environment variable for that and /bin/sh doesn't support this feature at all.
 
Thank You !!!

I obviously read wrong :)

I have now added the line:
Code: 
set     autologout=60
to the users' .cshrc and it works perfect.

BTW, autologout is in minutes, while ClientAliveInterval is -as you said- in seconds.
