Hey, #define PERM_INSECURE (S_IRUSR|S_IWUSR|S_IRGRP|S_IROTH) #define PERM_SECURE (S_IRUSR|S_IWUSR) Thanks, removing S_IROTH worked :-) While we're at it, what is the cause for the system changing permissions when I install a port ? (ie /usr/local/sbin and /usr/local/www) As I've said in my previous mail, changing the mtree/ files to reflect my desired permissions sounded logical, but either I failed some step or it isn't the way to go. > On Sun, Mar 20, 2005 at 01:26:57PM -0600, H.
