On an unpatched Centos 4.4 system I chmod'd /usr/bin/sudo to ug+s, and set the filesystem in /etc/fstab to defaults,nosetuid. Reboot, and am told sudo needs to be set to setuid root. An ls -l shows rwsrws-- root root sudo I had to use a rescue CD to undo /etc/fstab for the filesystem partition so sudo would work. What am I missing? Thanks. Scott
