I have researched the networking HOWTO and searched the posts to no avail.

Here is the problem:
I have 2 machines and an Adelphia cable internet connection. My main machine is running Mandrake 9.2 with 2 ethernet cards eth0 and eth1, connected to the net and both cards are working.
The other machine is running Slackware 9.1 with 1 ethernet card and it works fine.

I gave the mandrake machine an ip address of 192.168.1.1 and the slack machine an ip address of 192.168.1.2 like this:
me@slackware:# ifconfig eth0 192.168.1.2 netmask 255.255.255.0 up
me@mandrake:# ifconfig eth0 192.168.1.1 netmask 255.255.255.0 up
Then
me@slackware:# route add -net 192.168.1.0 netmask 255.255.255.0 eth0
me@slackware:# route add default gw 192.168.1.1 eth0

Slackware:
/etc/hosts
127.0.0.1 localhost loopback
192.168.1.2 slackware.home.org slackware

Mandrake:
/etc/hosts
127.0.0.1 localhost loopback
192.168.1.1 mandrake.home.org mandrake

/etc/resolv.conf
domain home.org
search bflony.adelphia.net local
nameserver 127.0.0.1
nameserver 68.168.224.165
nameserver 68.168.224.162

When I try and connect to the mandrake box, the RX packets on eth1 go up, but I can't connect.

My questions are:
1. Why can't I get the two machines to ping or talk to each other?
2. How do I set it up so I may connect to the net with the slackware box?
3. What programs are good for talking to another machine? (ssh, telnet, webmin, nfs)

Thanks,
JL

Put all of your address in /etc/hosts:
127.0.0.1 localhost loopback
192.168.1.2 slackware.home.org slackware
192.168.1.1 mandrake.home.org mandrake

You are missing entries for each others computer in your /etc/hosts file.
You will want to run the MCC -> Internet Connection Sharing wizard on the Mandrake computer. This will set up the NAT translation for you.

Thanks for your reply.

Honestly, at one point I had the proper entries in the /etc/hosts file. I wasn't familiar with NAT and I would prefer to do it command line as the internet connection wizard doesn't let me alter the eth1 settings only eth0.

What steps do I need to take and what am I missing?

Can anyone answer my other questions?

Apparently, the firewall on my Mandrake box was the problem. I am now able to ping from each system. I still don't know how to make the Slackware box access the net.

Guess I have to figure it out on my own.

I have a cable router so I didn't have to use the network sharing wizard, however, since a second NIC card is manditory for sharing the network connection, I don't believe that it uses only one card.

Try getting the internet connection working on that interface first on eth1.
Then get the networking setup between your two computers on the 192.168.0.0 network.

I believe that the wizards use drop down boxes to select the interface you want to work with.

From the ipconfig outputs, If doesn't look like any of your interfaces are connecting.

There is an /etc/network subdirectory that contains the scripts that run to start up your network. The wizards should take care of settng them up properly.

jschiwal,
The internet connection works on the Mandrake computer, just look at the ifconfig output in my original post and you will see that it has an ip of 24.50.126.45.

I did get the 2 computers talking, like I said it was my firewall. Also, I am not interested in using a brainless wizard. I prefer command line, as I never login to the window system. I only use Mandrake, because I have turned a few people onto it and it is easier for me to help them if I have it installed on my main box.

The only real issue now is to get the Slackware box to connect to the internet thru the Mandrake box. Everything else is ready to go!

How do I turn the Mandrake box into a router? That's the big question.
