[Trisquel-users] Re : How to remove "su"/"sudo"/"root" timeout?

That is what I had understood: never use 'su', 'sudo -i' or 'sudo -s' then. According to http://www.howtogeek.com/116757/8-ways-to-tweak-and-configure-sudo-on-ubuntu/ trinux is right: setting, with 'sudo visudo', "passwd_timeout" to 0 makes 'sudo' always ask for a password.

My understanding is that "no timeout" means the password never expires! If I am right, you had better set "passwd_timeout" to 0.1, which is one tenth of a minute, i.e., 6s.
