ppp/local network config

[Russell Brunet]

Hi all!

I'm trying to configure my local network on my yellowdog G4. I am also trying to connect to the internet via ppp. Let's talk about ppp first. 

My isp is earthlink and I can connect to it fine using os X, 9.2, and RedHat on my pentium II. I tried to copy my settings from the RedHat machine and I am having all kinds of problems. First, I can connect fine. The modem works great, I can hear it dial, it connects and brings up a status menu in the kde panel (btw, I'm connecting using kppp). Once connected I try to use a tcp/ip application and I cannot get any address to resolve. I use nslookup in the terminal and I get errors. I try to ping yahoo and I get errors. Occasionally if I fart around with things for a while, I am able to get connected and everything is hunkydory. After I restart, though, it's back to the drawing board. I did just notice that when I try to enter any dns addresses in the network configuration panel and save them, none of them are there when I reopen the network config panel.

Again, I have no problem whatsoever on my RedHat box, and I'm using all of the same settings.

Ok, now on to my second question which may be related. I want to be able to send files back and forth between my RedHat box and my YellowDog box. How do I set up a standalone self-contained network using a crossover cable between the two computers?

Thank in advance for any help you can provide,

Russell
