I did see that earlier message, but it's not the information I'm
seeking. You say that both computers are linked to a satellite dish,
but I'm asking for information about what is between your computers
and the dish. You should have ethernet cables running from each
computer to some sort of box. Can you describe that box for us? For
the moment (or for the rest of this message, I will refer to it as
Also another point of confusion is that we may be talking about two
different DHCP servers. One of them is at your ISPs offices and
assigns an IP address (and other stuff) to your home (actually to Box
R). It will assign a public IP address like 126.96.36.199 as a non-
The other one (the one that I'm interested in) is on your premises
and assigns IP addresses to the two machines. It is what I think Box
R is. It will assign addresses like 192.168.1.100 and
192.168.1.101. This Box R is what is giving your server an IP
address. And that address may change.
You need to give your server a fixed IP address, say 192.168.1.6.
This can be done using the sysinstall GUI for network set up. But
here is the hitch. You don't want it to have the same IP address as
something that Box R might assign. This is why I want you to look at
the DHCP configuration on Box R. Maybe Box R gives out IP addresses
(DHCP pool) in the range 192.168.1.100-199, or maybe some other
range. The IP address that you pick for your server should be on
the local net, but not in the DHCP pool.
I need more information about box R to be able to tell you how to log
on to it.
On your local network it probably (but not necessarily) has the IP
address 192.168.1.1 or 192.168.0.1 all depending on its default
settings. Try pointing a web browser (from one of your two machines)
to either of those addresses and see if you get anything. When you
get the right address you should be prompted for a username and
password. We'll need to know more about the Box R to know what the
password is, but a good first guess is always Username: admin,
Password: admin. (of course once you do get into Box R change the
password to something else).
Please keep in mind that all of this is just diagnostic. This
information is not guaranteed to lead me to a solution. But it will
help in understanding your network.

ifconfig (or the GUI sysinstall) will be the way to set the IP
address of your server. Nothing that I've said contradicts any of
the other advice you've received here. But to pick the right IP
address it is good to know what Box R's DHCP range is. Also, later
on, it may be that some configuring of Box R will be needed for what
you are trying to do.
So the advice that you are getting is multi-pronged. So far most of
the advice you've had has been in the form of "do X and report back
here so that we know more about your network".
