How to increase SSH connection timeout in Linux

Recommended Steps to increase SSH connection timeout

​

We can use the following way to increase the SSH connection timeout in Linux.

​

• add ServerAliveInterval 20 and ServerAliveCountMax 100 on client-side in file ~/.ssh/ssh\_config or we can add them to command line like this $ ssh -o ServerAliveInterval=20 -o ServerAliveCountMax=100 user@example.com
• change TMOUT variable on server-side with the following command.

​

Commands to change TMOUT value on server side

​

• TMOUT=600 ( this is 10 minutes).
• export TMOUT
• echo $TMOUT

​

This will keep the SSH connection alive for 10 minutes. We can change TMOUT value for a longer SSH connection timeout value if needed.
