sudo version 1.7.4 on Debian squeeze. In this version, unlike some older versions, every pty has to be authorized separately with a password and timeout. In older versions, one password was good for any pty during the timeout period. I'd like to persuade
sudo to revert to that older behavior, so that I can use a bunch of xterm windows without having to retype my password continually. Does anyone know how to do this?
Have a look at the tty_tickets option
From the man page
If set, users must authenticate on a per-tty basis. With this flag enabled, sudo will >use a file named for the tty the user is logged in on in the user's time stamp directory. If >disabled, the time stamp of the directory is used instead. This flag is on by default
To disable this behaviour set
Defaults ! tty_tickets
