The easiest way is to set up the network environment during the
install procedure. When you're using any network media to install
(vi NFS or ftp) you're asked about IP number, default gateway,
netmask and so on. This becomes the default.
For giving you exact information on how to set up your local area
network, we would need more information - do you have a registered
class C network, do you plan to split your class C network to
sub networks? I'm assuming you have your own little LAN and no
registered network and no sub networks - this is the easiest way :-)
On a running system, have a look at the following files:
=======> /etc/hosts
# $Id: hosts,v 1.2 1993/11/11 22:32:36 wollman Exp $
#
# Host Database
# This file should contain the addresses and aliases
# for local hosts that share this file.
# In the presence of the domain name service or NIS, this file may
# not be consulted at all; see /etc/host.conf for the resolution order.
#
#
127.0.0.1 localhost localhost.my.domain
#
# Imaginary network.
#0.2 myname.my.domain myname
#0.3 myfriend.my.domain myfriend
#
# NB: 0 is not a valid network number. PLEASE PLEASE PLEASE do not try
# to invent your own network numbers but instead get one from your
# network provider (if any) or from the Internet Registry (ftp to
# rs.internic.net, directory `/templates').
#
You need to assign some IP numbers to your hosts.
Unless you have a registered class C network (the first three bytes,
for example 193.28.3 or 193.175.26), you should use some of those
numbers reserved for usage in LANs, that means, not on the world-
wide Internet. I'm sorry that I can't look up which numbers this
are now, but feel free to use any number you like, as long as you
don't try to use them dialing to your IP provider :-)
For example, add those entries:
1.0.0.1 freebsd
1.0.0.2 windoze
(I call the machines freebsd and windoze - you may give 'em any
name you like, of course. But those names make it easier.)
I know that we wouldn't even need a change of /etc/hosts but
I find using hostnames rather than IP numbers more comfortable.

######################### End Of Netconfig Section #######################
That should be all if you have done a standard installation, that
means, the distribution defaults are set (geee, that's what makes
me like FreeBSD, using Linux I would have to ask ``what distribution
is it you're using, what version, what side of the CD did you use
when installing'' - please don't take me to serious!)
Try something like a telnet or ftp to your FreeBSD box and it
should work. Try a ``ping windoze'' on your FreeBSD machine (assuming
that you properly configured the other host) and it should already
answer.
Ah, of course, after making the changes to /etc/hosts and
/etc/sysconfig, don't forget to reboot your machine so that the
settings become used. Of course you could change your configuration
without rebooting, but this makes it easier for you (I don't want
to bore you with ifconfig commands and so on, although it isn't
really much more difficult than entering reboot :-) )
I hope, this was what you wanted.
Bye,
Martin
