I'm running 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 

in your sudoers file.

  • Exactly what I needed. Just couldn't find that option amongst the 50 other options available. Thank you! – Norman Ramsey Oct 23 '11 at 4:24
