Could I suggest three things to try:
1) Install mprime with suid privelege. This should enable mprime to
read /proc/net as though it were running under root even though it's
actually running under an unpriveleged user.
2) Get out your hacker's hat and fix the problem in the source code.
I'd guess that all you need to change is the code which creates the
/proc pseudofilesystem at boot time. As you've probably found, you
don't seem to be able to change the permissions on "files" in the
/proc tree on a running system - even if you _are_ root.
3) Is Mandrake really linux, or just a linux clone? I think the
latter. If I'm right, then perhaps switching to a genuine linux (Red
Hat, or SuSe) might be a sensible thing to do. Though the official
Red Hat distribution retail package is expensive, you can get just
the CD for about $2, or download the distribution FoC (not
reccomended unless you have fast internet access!)
