Automatically log out inactive users after login timeout in Linux

Method 1: Modify the .bashrc or .bash_profile file

This can be achieved by modifying the .bashrc or .bash_profile file in the home directory. Choose one of the two files and add the following line at the end. The specific operations are as follows:

[GeekDevOps@GeekDevOps /]$ cd ~
[GeekDevOps@GeekDevOps ~]$ echo "TMOUT=90">>.bashrc 
[GeekDevOps@GeekDevOps ~]$ source .bashrc

In the above code, we selected the .bashrc file. If you choose .bash_profile, the operation process is the same. Above, we set the user's automatic logout time to 90 seconds. After 90 seconds, the screen will display as follows:

[GeekDevOps@GeekDevOps ~]$ Timeout waiting for input: Automatically log out Connection closing...Socket close.
Connection closed by foreign host.
Disconnected from remote host(10.1.1.21:22) at 16:38:48.

Method 2: Implement by modifying the ssh configuration file

ssh is a tool that we often use in Linux systems. By modifying the ssh configuration file /etc/ssh/sshd_config we can also implement the timeout automatic logout function, as follows:

[root@GeekDevOps ~]# vim /etc/ssh/sshd_config

Find the following two lines:

#ClientAliveInterval 90
#ClientAliveCountMax 3

Remove the comments and modify the following numbers:

ClientAliveInterval 60
ClientAliveCountMax 5

After saving and exiting, restart the ssh service:

[root@GeekDevOps ~]# service sshd restart

This method will cause a 60-second login timeout for all users except root, and they will be automatically logged out. The first line indicates that the connection will be disconnected after 5 inactivity detections, while the second line indicates that the connection will be disconnected after 5 inactivity detections.

Method 3: Implement by modifying the ssh configuration file

In the /etc/profile file, add the TMOUT field and then source /etc/profile.

TMOUT=300
export TOMOUT

Method 4: Create a script

Log in as root and create a new file called autologout.sh.

vim /etc/profile.d/autologout.sh

Add the following content:

TMOUT=100
readonly TMOUT
export TMOUT

Save and exit the file, and give it executable permissions:

chmod +x /etc/profile.d/autologout.sh

Now, log out or reboot your system. Inactive users will be automatically logged out after 100 seconds. Even if ordinary users want to keep the session connection, they cannot modify this configuration and will be forced to log out after 100 seconds.
