This days, I am
using Putty often and when I left my desk for a while or I am busy
with other tasks the Putty (inactive) problem occurs. I have found, it
happens because servers are configured to disconnect idle sessions after they
are inactive for a particular time. This has many disadvantages. You can no
longer monitor the jobs running in the background and you have to enter the
username and password again after restarting the session.
This is how you keep it alive.
- Open putty connection, Right click on Putty title bar and then click on Change Setting... option.
- Click on Connection in the left pane.
- Enter a number in the text box, in place of zero and save this by pressing Apply button.
- Go back and Save your session so that this setting will be same for future.
This way, the session sends a keep-alive request to the server every 30 seconds
and it stays active.
