If the user is running a non-standard kernel (such as kernel-PAE), then the -devel package must be installed manually (kernel-PAE-devel, for example).

Hi Rafał,
I've had a quick look at consolehelper, and I'm still not sure I fully
understand how it works, at least enough to be able to write a section
on it. I understand it uses pam authentication when running a program
that requires root privileges and requests the root password
(system-config-services being an example), but I don't fully understand
how a user would use it, although I see any application could
potentially be configured in /etc/pam.d/
My initial intent was to write a short article to be useful to beginners
explaining how they could become root in order to achieve common tasks
(as opposed to logging in to the GUI desktop as root!) and highlight
some of the common pitfalls ('su' vs 'su -'), as much to serve as a
quick FAQ for forum helpers to link to rather than explaining it over
and over again. I fear it is beyond my abilities/knowledge to expand the
article much further than this.
How far such an article should be expanded, and whether we wish to cover
every conceivable method for launching something with root privileges is
probably not something for me to answer. That said, if you'd (or anyone)
like to expand on my initial remit and write an additional section,
please feel free :)
On an additional note, whilst investigating consolehelper, I also
noticed the Run Command... option on the KDE Menu (for those who don't
use KDE, it's a graphical run box that also allows one to specify a
different users credentials). I could see how that would be useful to
new users who are afraid of the command line, and should maybe be
included, but again I have no knowledge of the underlying mechanism by
which it works. Perhaps a gnome user could advise if gnome has similar
functionality?

Ned

Hi, Ned. You wrote: I've had a quick look at consolehelper, and I'm still not sure I fully understand how it works, at least enough to be able to write a section on it.

I realize of course that ordinary user mustn't mess with pam :^) , but admin-beginner should know about that method, and our HOWTO could be a good introduction. Of course we shouldn't explain every pam module here, just the basic config. I'm doing most of my admin job in console with sudo, but I know that if my users migrate one day from XP to Linux, they will not want to use su/sudo to run programs with raised privileges. How far such an article should be expanded, and whether we wish to cover every conceivable method for launching something with root privileges is probably not something for me to answer. That said, if you'd (or anyone) like to expand on my initial remit and write an additional section, please feel free :) I've mentioned consolehelper just because I think I can write such section. Of course it should be proofreaded because of my English. On an additional note, whilst investigating consolehelper, I also noticed the Run Command... option on the KDE Menu (...). Perhaps a gnome user could advise if gnome has similar functionality? There is a gnomesu (http://xsu.sourceforge.net/) project.

Re: [CentOS-docs] becoming root
2008/4/8, Ned Slider [EMAIL PROTECTED]: I've put up a draft page here to get us started: http://wiki.centos.org/TipsAndTricks/BecomingRoot Do you have edit permissions? If not, hopefully Ralph can get you fixed up. No, I have edit permissions only for Laptops. My username is RafalSlubowski - Ralph, could you give me rights to TipsAndTricks? There is a gnomesu (http://xsu.sourceforge.net/) project. Is this included on a standard CentOS gnome install? I don't think so - yum cannot find it.

OK, thanks, I might have to fire up gnome and have a browse through the menus to see if there's anything similar to the Run Command... in KDE. One would think gnome would have some sort of GUI run as root applet somewhere?? ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs
