The permissions on these two files should be:- -r-xr-sr-x 2 bin kmem 16384 Nov 16 09:55 /usr/bin/w -r-sr-sr-x 3 root kmem 180224 Nov 16 09:59 /usr/sbin/sendmail Most of the files in /usr/sbin are -r-xr-xr-x, but quite a number of them are setuid and/or setgid, as they need to access certain files that are not available to just anyone. However, don't go around making things setuid or setgid unless you know what you're doing, as this can cause potential security problems. If you have the CDs for 2.0.5 or 2.1.0, they come with an extra CD that has a copy of a complete working system on it, which is useful for situations like this.
