Excellent! This worked.
What I was doing wrong was including the "ether" value as part of a
complete string. For example:
ifconfig dc0 192.168.1.1 netmask 255.255.255.0 ether 00:00:00:00:00:00
This would return an error. This appearently has to do with the layer
the MAC works on versus the IP--since they're on different layers I have
to configure them seperately.
Thanks for the input. Thanks also to the other poster, Louis LeBlanc.
FYI to Louis: If you add a line, as follows, in your /etc/rc.conf you
can be ride of the "start_if.x10" file.
I thought this may prove useful to you.
