Hi

I notice this in my kernel logs:

Sep 18 18:13:24 dove /kernel: ipfw: 200 Deny UDP 1.2.3.4:138 
127.255.255.255:138 out via ppp0

so i decided to look at the lo0 interface and the routes.

now lo0 is configured like this:
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000 

notice the netmask.

the route looks like this:
Destination        Gateway            Flags     Refs     Use     Netif Expire
127.0.0.1          127.0.0.1          UH          1     4629      lo0

shouldn't the route be for 127.0.0.0/8 because of the netmask?

I've added the route for 127/8 manually so samba can talk to itself via 
lo0 but is this a bug in ifconfig or is it normal behavior?

thanks
keith

p.s. please cc replies to me
