Seems you would have had to be root to change the permissions anyway... visudo exists in /sbin, so until you edit sudoers to allow user to use it, you need to be root. Also, the EDITOR variable is undeclared, so until you add that to .bashrc or whatever you'll need to do: sudo gainroot EDITOR="vi" visudo You can of course use something other than vi if you want. --Paul > > > > Nick. > > > > ________________________________ > > > From: maemo-users-bounces at maemo.org [mailto:maemo-users-bounces at maemo.org] > On Behalf Of Paul Klapperich > Sent: Wednesday, August 15, 2007 9:38 PM > Cc: maemo-users at maemo.org > Subject: Re: Visudo Help > > > > > I'm not sure if it has visudo or not and my unit isn't handy, but here's a > safety net: > > Install OpenSSH or Dropbear, then do > sudo gainroot > passwd > enter a root password > > Now if you mess up your /etc/sudoers, you can always open Putty/Xterm on > your desktop and ssh into the root account using the root password you > created.
