Hello,
I was wondering if it was possible to limit user access on /proc
without having to use securelevels.
For some reason chmod 751 /proc (or 750) does nothing.
Is this possible on FreeBSD 4.9 ? Can't find anything about it in the
manual pages. Just want to prevent lusers from running:
for file in /proc/*/cmdline; do cat $file; echo; done
Greetz,
Jimmy Scott
