Dear Michael,

[kjkoster@saffron ~]$ ifconfig bge0
bge0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu =
	ether 00:e0:81:32:ed:b4
	inet netmask 0xfffffff8 broadcast
	inet netmask 0xffffffff broadcast
	media: Ethernet autoselect (100baseTX =
	status: active
[kjkoster@saffron ~]$ fgrep bge0 /etc/rc.conf=20
ifconfig_bge0=3D"inet netmask"
ifconfig_bge0_alias0=3D" netmask"

That broadcast address and netmask look wrong for sure.

Should I just change that to as well?

Kees Jan

I hate unit tests; I much prefer the illusion that there are no errors =
in my code.
