1. SElinux is disabled
2. the fstab entry for / is equal to the F14 / fstab entry (without suid
mount) , but in F14 and previous fedora version I never had problems as
normal user with ping! But one thing is weird:
ls -l /bin/ping
-rwxr-xr-x. 1 backes backes 40840 Feb 9 17:00 /bin/ping
But
chown root.root /bin/ping
does not solve the problem, still "operation not permitted", even after
chmod u+s /bin/ping.
Kind regards
