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

In any case I suggest to Install Webmin (that you can download at
Www.webmin.com)
