SUSE 7.3 Network Probs, Help!


OK, I've got SUSE 7.3 on my brand new laptop (Mandrake&Redhat couldn't recognize the monitor) and it rocks! I'm very impressed but for I can't can't get on the internet. Have a cable modem going to a 192.168.1.x network and using static addresses and NAT and 2 DNS servers. I enter the static address for my machine (192.168.1.24), the subnetmask (255.2.55.255.0), host name (linux byu default), the domain name (local bu default), and the IP addresses of the 2 DNS servers of my ISP (Cox@Home). Yet I have no connectivity! Seems like my box is not finding my DNS servers. Help!

Basics first:
-Can you ping your NIC?
-Can you ping other boxen on the internal network?
-Can you ping outside addresses (ping your DNS servers' IPs, or try 209.133.27.161)?
-Cox runs DHCP, right? Is your DHCP client running?
-How are you connecting your internal network to the cable modem, and what is providing NAT? If it's a stand-alone router,or a box set up as a router, you'll have to enter its (internal) IP as the gateway.

Depending on how you connect to the outside world, the hostname and domain name that Cox gave you will have to be entered somewhere (hostname= the "cxNNNNNN-a" part, domain= the "bla.cox.home.com" part).

Can ping 127.0.0.1. Can't ping anything else including local addresses. Don't know how to check if DHCP client is running. Internal network is cable modem to Linksys router running NAT to switch on 192.168.1.x subnet. The network is fine, all othe rcomputers are up. Enetering same gateway as used in Mandrake and redhat (192.168.1.1) and it worked in othe rdistros and Windows. I think SUSE doesn't want to run a static IP and DHCP.

Woops, missed the fact that you said you're using static IPs on the internal net. That's the same setup I have, except that I'm using a Netgear router. So the Linksys is taking care of talking to Cox, and the other machines on the LAN are working, which means DHCP vs static isn't the issue.

If you can't even ping the NIC, then it's a problem with your card's setup, not your network/internet configuration. What kind of card is it, and what module is it using?
Do you see any info for the NIC when you run ifconfig, or do you just get stats for lo? If ifconfig doesn't show anything for eth0, try ifconfig -a. The -a option forces ifconfig to list all interfaces, including inactive ones. Also, since it's a PCMCIA card, check out the PCMCIA Info page for more on configuring PCMCIA services and troubleshooting. Sorry I can't help with that one, but haven't run Linux on a laptop yet.
