Re: [SLUG] rights of root from su
which did you use? su or su - su will give you root priviliges with your path su - will give you root with root's paths. Thank you very much.. this is now clear. I sort of relised that su did not change environment variables...but thought that if user had access to X --or modem-- root ought to as well. I did not understand the man page :-( Geoffrey -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] rights of root from su
Because of X authorisation (xauth). If you are the only using this box, do a 'xhost localhost' before su'ing. This will allow anyone on the local machine to connect. Yes, only I am only user, so this will be fine, but thank you for other note. Now I know what to look I think I can do it .. many thanks Geoffrey -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

For the special case of root (since root can read everyone's files), you're better off doing as others have suggested and setting XAUTHORITY to the relevant user's .Xauthority file. If your gaining root process doesn't change $HOME (eg sudo without -H, su with -m or -p), then it should find the right .Xauthority file ok anyway. -- - Gus -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] rights of root from su
sorry for such an elementary Q... :-( I thought you could do ANYTHING as root.. Debian Woody -- su to root to install e.g. OO.o, error message: glibc version: 2.2.5 Xlib: connection to :0.0 refused by server Xlib: Client is not authorized to connect to Server ./setup: cannot connect to X server :0 so I have to logout as user and login as root on X11... why? (or should I just install as user?) Geoffrey -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

If you're not the only one, well don't do this, use xauth instead; export the xauth cookie from your account and import to root's xauth. (let me know if you a detailed howto; or google for it) Or ... you might try ssh'ing to the same machine, and login as root (if you can). This will end up using the original accounts authorisation. I believe there is a PAM module for X that you tell su to do option 1 above automgically, but the details escape me at the mo.

It's not affected by the user ID of the user trying to connect, it just makes sure that user can present the right credentials to be allowed access. This is usually stored in .Xauthority in your home directory. So, after su'ing, run # export XAUTHORITY=/path/to/homedir/.Xauthority (where /path/to/homedir is, of course, the path to your regular user's home directory, usually /home/username) -- Pete -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Xlib: connection to :0.0 refused by server Xlib: Client is not authorized to connect to Server ./setup: cannot connect to X server :0 so I have to logout as user and login as root on X11... why? this works on RH/Fedora but it is a bit of a nasty hack :-), for Debian after su'ing do export XAUTHORITY=/home/yourhomedir/.Xauthority and life should be okay...
