On one of the workstations: '/sbin/ifconfig -a' '/sbin/route -n' and
'cat /etc/resolv.conf'. Newbies tend to not understand the specifics
of the numbers presented, and make mistakes.

Is that the same netmask that shows up in the 'ifconfig' and 'route' data?

The gateway will be another address on the 10.x.x.x network, and noone cares
what it is, as it is not reachable from the Internet. (A million people use
that address range - which one are you? That's why it's blocked at the ISP
level.) It will NOT be 198.53.233.79 or similar.
>he could not acsess any thing
What is in his HOSTS file? What names you use on your 10.x.x.x network,
are unknown to any name server elsewhere. This also means that _your_
/etc/hosts files (on all three computers) need to have the appropriate
information in them. Is he able to resolve common Internet names like
www.google.com? How about using the IP address instead of the name (use
'ping -c 1
www.google.com to get they address they are using at the moment).
If not, his network setup is in error - likely a gateway problem. In not
by name, but the IP method works, the loose-box has no working name servers
listed. It could also be a firewall problem if you are only allowing
traffic from the exact IP addresses you have assigned. '/sbin/iptables -Ln'
on the router should show the rules.
>according to properties he was sending but not reviving.
Using 'tcpdump' on your router might tell you what problems are occurring.
Hopefully, he's trying to use standard network protocols and not the toy
microsoft imitations (network neighborhood only works when you are running
Samba).

People can't read your mind, so you do have to show information as above.
On your 'gateway/firewall/router' box, you don't need to show the IP
address assigned to the Internet interface, as that isn't important to
the problem (I'm assuming you can reach the Internet from your workstations,
so that rules out a basic problem there). As far as security/paranoia is
concerned, your 10.x.x.x addresses are meaningless to the world, but may
be meaningful to your problem.

Should be on your system, probably in /usr/share/HOWTO/.
