If there are many users who access to your system, it’s dangerous and resource-consuming when users keep their ssh connection for a long time. In this post, I would like to show you some methods to auto-disconnect ssh session after a period of time.
Method 1: Using .bashrc
In the /home/user/.bashrc or /home/user/.bash_profile, add following line:
|
1 |
TMOUT=<number of seconds> |
Method 2: Using sshd_config
In /etc/ssh/sshd_config, add:
|
1 2 |
ClientAliveInterval <number of seconds> ClientAliveCountMax 0 |
Then, you need to restart the ssd service to apply changes.
Method 3: Using script in /etc/profile.d/
In /etc/profile.d/, create a autodisconnect.sh with the following contents:
|
1 2 3 |
TMOUT=<number of seconds> readonly TMOUT export TMOUT |
Note that, you need to make the script executable, the script will be run at OS startup to enable disconnecting.
