The problem with this one is that if you changed your ethernet
card, you might forget about the /etc/start_if.ed1 file. But isn't there
a easier way to do it?

I know, I lost the reply and couldn't find it. I found this in
the FreeBSD Mailig List archives, would this also work?

This is the answer to a similar question posted a few weeks ago ( and

I have no idea how this might be done with ppp or slip, but on ethernet
the
following:
ifconfig <device> alias <ip alias>
route add <ip alias> 127.0.0.1
Lazy way to make this permanent: Add these commands to /etc/rc.local
More scalable way to permanency:
Add the following to /etc/sysconfig: (put them with like config options)
--
# network interface aliases
interface_aliases="ed1"
alias_ed1="alias x.x.x.x"
route_alias1="x.x.x.x 127.0.0.1"
--
Add the word alias1 to the static_routes= definition.
Add the following to /etc/netstart:
--
# Set up any aliases to network interfaces.
for device in ${interface_aliases}; do
eval ifconfig_args=\$alias_${device}
ifconfig ${device} ${ifconfig_args}
done
--
This way if you have more than one alias on an interface you just have:
alias_ed1="alias x.x.x.x alias y.y.y.y alias z.z.z.z"
route_alias1="x.x.x.x 127.0.0.1"
route_alias2="y.y.y.y 127.0.0.1"
route_alias3="z.z.z.z 127.0.0.1"
static_routes="multicast alias1 alias2 alias3 loopback"
All of your network config info is still in one file this way and you
can easily see the aliases assigned to an interface.
