Hi Clive, I sent the message below more than 12 hours ago to the debian-user list: I didn't see it there until now, so I'll try to send it again.
BTW: I definitely don't know whether my suggestions below will work in a network. I tested them, as I'll write below, only on a single machine where they work ... HTH Nice week-end.

Hi Clive I'd always try to do things as much and as often as possible as non-root: Some time ago I removed my complete .mozilla files by hitting the Enter key accidentally, and a bit too early: rm -rf .mozilla/ Was a nice moment to realise, you'll certainly believe .. (actually I simply wanted to remove the stuff in the Mozilla Cache ... ) I'd think it means shouting for problems if someone tries to become root unnecessarily. Provided I understand you correctly you suggest to log out of your non-root and user X to enter an X-session as root: IIRC I even set Gnome to forbid root to start an X-session here: I know how fast I make mistakes on X .... :) Here's the URL for CUPS where the documentation for authentication stuff starts, IINM: <http://localhost:631/sam.html#AuthClass> And here's a /etc/cups/cupsd.conf that allows only users in group foo, on one machine with several users, to manage the CUPS printing system, and only after he or she provided their username/passwd ... [ /etc/groups file .... adduser <user-login-name> foo ... login ... logout .. IIRC ] I didn't test so far whether this also works on a network connected to some printer, but I'd believe it could work ... not being sure on that .. At least here on http://localhost:631 on a single machine with several users: after some initial tests it seems to work: Here's the corresponding cupsd.conf: --------------------------- LogLevel debug Printcap /var/run/cups/printcap <Location /> Order Deny,Allow Deny From All Allow From 127.0.0.1 </Location> <Location /admin> AuthType Basic AuthClass Group AuthGroupName foo Order Deny,Allow Deny From All Allow From 127.0.0.1 </Location> ---------------------------------- So with this last cupsd.conf it seems you don't need to be root to change your CUPS settings and you can decide who of the users on a machine will be able to to change these settings ... I swear I love this crap, at least some times ..... :) PS: I'd cp -r /etc/cups/ /path/to/other/directory/cups.working before changing some printer settings ... :) HTH, too ...
