Configure DSL and Linux network
 

Dear Experts,

I have 2 XP/Linux dual boot machines.

Previously, these machines were connected with a
crossover cable, and they could talk to each other.
But now, there is a DSL modem, and router that
is not configured right.

I have installed DSL on the XP side, and it is working well.
Now, I'm trying to get it to work on Linux. First and
foremost, I need the two Linux machines to talk to each
other, through the router. Internet is secondary.
Wireless is completely unnecessary, and unwanted.

So far, I can't even ping the modem, or router, so
some fundamental configuration is needed.


Hardware:
The IP addresses are what is configured on the XP side.

2 XP/Linux dual boot machines
192.168.2.2 - white
192.168.2.3 - red


(Westell) DSL modem with Verizon
192.168.1.1


Belkin Wireless G router
192.168.2.1
also
192.168.1.47



Linux: Redhat 3.2
Kernel: 2.4.21-27.0.2.ELorafw1


I want the private network to be called:
testrac.com


The IP addresses need to be static.


--------------------------

Here is some analysis.

[root@red notes]# ping 192.168.1.1
connect: Network is unreachable

[root@red notes]# ping 192.168.1.47
connect: Network is unreachable

Fortunately, the machine can ping itself.


cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.2.3 red.testrac.com red

I've been looking for a good how-to on the web, but
can't find anything concise. If you know of some
good concise web pages, please refer me to them.

Or, if you know what I need to do, please let
me know.


Thanks!

Subnet
 

The problem i see is that you are on two different subnets. You are probably using a netmask of 255.255.255.0 and 192.168.1.0 cannot access 192.168.2.0. An easy fix would be to put them all on one subnet or change the netmask to 255.255.0.0. Another way would be to implement some routing rules on the router so that the router can route the two different subnets accordingly.
