Run "ls -ld /tmp" and you should see: drwxrwxrwt. 17 root root 4096 2010-04-23 14:37 /tmp The "t" at the end (instead of a normal "x") indicates the directory sticky bit. > Also in what situations would seting the setuid or setgid bits help?

Setting them on arbitrary programs is a security problem (since you could be giving any user the ability to do random things as another user, possibly root). -- Chris Adams <cmadams@xxxxxxxxxx> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
