Increase Linux SSH Connection Timeout Quick Guide

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 [e-mail]
• 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.
