If I am using the command line in xterm, gnome-terminal, etc., I can keep
sudo from re-prompting for a password, within some limits, or I can disable it.
As a compromise between usability and security, I usually just want this re-querying wait-time lengthened.
By default, there is only a 15 minute grace-period after entering a sudo password before it prompts for it again. To change this to 45 minutes, I can edit
/etc/sudoers, and set timestamp_timeout to the waiting period I want (in minutes) .
If I am within the same terminal session, and start a new shell (typing in
bash) the wait period is respected.
But if I go to another window to access the command line there, it will immediately ask for my password if I try to
Within the same pseudoterminal session (
pts) (for example, if I spawn a new shell inside the same gnome-terminal window), the timeout is respected.
If I launch a new xterm, gnome-terminal, etc., I must enter credentials again.
Despite being the only user active on my home system (a single-user system), etc., sudo doesn't trust that all of my
pts entries are from the same user:

Is there a way to tell sudo that it should regard all the windows I open as coming from the same user, and to not ask again for my password if the last sudo timer hasn't expired?
