How to change sudo cache timeout

May 19, 2009

For those who wishes to change the sudo cache timeout for a specific user, let’s userA

sudo visudo or (su - then visudo)

Defaults:userA timestamp_timeout=20

We have now set the sudo timeout “password-less” prompt to 20mn, to make it infinite set it to -1

If for some reasons you have it set it to 20 or -1 and wish to re-enable the password prompt, simple type sudo -K

** remember even after a reboot, the sudo cache would still persist if it is of course in its timeout grace time.

Have a look in /var/run/sudo/userA/ and it will all be clear :)

I hope that was informative :)
