3.4.-stable-9912201156
this is new and exciting. it used to work, and still does over on a 3.3-RC
system. i imagine i have fumbled something, but don't know what.
in /etc/rc.conf
network_interfaces="fxp0 lo0" # List of network interfaces (lo0 is loopback).
ifconfig_fxp0="inet 147.28.0.39 netmask 255.255.255.0"
ifconfig_fxp0_alias0="inet 147.28.0.3 netmask 255.255.255.0"
ifconfig_fxp0_alias1="inet 147.28.0.4 netmask 255.255.255.0"
