I'm not sure that is a huge issue, but it seems relevant. Sure, that should be: sysctl -w net.inet.tcp.25=`id smtp` sysctl -w net.inet.udp.53=`id named` or whatever. No biggie. Of course, we already have a permissions system. Why not: -rw-rw---- 1 root smtp Feb 18 09:33 /protocols/inet/tcp/25 Or is that just too weird? Jim Shankland Flying Fox Computer Systems, Inc.
