For what duration is sudo_root in "don't-prompt-for-password" mode?

The first time a user enters sudo foo, sudo_root prompts for the password. For a certain duration after that, sudo_root doesn't prompt for a password for any subsequent sudo foo's in that terminal session.

  • What duration is that?
  • Can the duration be changed?
command-line sudo

    This is covered in the Ubuntu Sudo FAQ entry here: https://wiki.ubuntu.com/SecurityTeam/FAQ#Sudo

    The default is 15 minutes, but can be changed with *timestamp_timeout* in /etc/sudoers. For more details see "man sudoers"
