My son tells me (we are working on this thing together) that I have an ethernet card and my external modem is on a serial port. Does this count? However, on the security issue, I don't know that hacking into our network would be the most interesting exercise, as my sons both assure me that it would put any self respecting hacker to sleep and their machines are full of school essays and compositions and no world shattering secrets at all. At this present time I would like to just get file tranfer between the machines up and running. Maybe later worry about letting them on the net, after all they can use my machine to do so.
I tried to install swat but something is missing or in another directory, because when I use the rpm install thing it tells me that it can't find samba 3. I'm sure that I have it because I did a complete install of everything from the CDs and there is a smb file that I found once in /etc. that looked like the one described in a book I bought to help me. I also have downloaded webmin which looks good but I have yet to install it. I hope it explains things like samba shares and the syntax for entering these mysteries. Are they things I want to share or can they be things the other machine wants to share? And if so how do I put it into the configuration gui? These are the thngs I have trouble with. (I also don't understand card game rules and can't add up 2 digit numbers in my head 'cause that means remembering numbers to carry over, and they disappear in the short time from one calculation to the next. Maybe it's all related!)

Should I find the relevant files and copy them so you can see where I stand at the present time?
(should I change the names to protect the innnocent?)

Internet sharig and file sharing are two completely separate issues.
1) I am on a hub and I have two separate cards (one for the Internet and one for home/office): setting is much easier and safer, and traffic is completely separate.Adding a card is cheap and easy.
You set the first card to Internet and try it: if it works you set the network parameters on second card.
But you have to tell the machine that is a router (see file /etc/systcl.con)
kernel.sysrq=0 net.ipv4.ip_forward=1 net.ipv4.conf.default.rp_filter=1 kernel.core_uses_pid=1
At this point you must tell the machine that must do some NAT (Network address translation) by setting appropriate iptables file in /etc/sysconfig
This is mine...with eth0 card to the internal and ppp0 as Internet connection

Samba configuration in a separate message after confirmation of success!!!
In any case I suggest to Install Webmin (that you can download at Www.webmin.com)
