Ethernet activates, but doesn't work

**necrotic** · 06-17-2004

Hey everyone,

I got my "new" (refurbished) computer in yesterday and got linux on it, after 10+ years of using Windows. Today I worked on getting it hooked up to ethernet and it hasn't worked so far. I tried 3 distros (Red Hat, Slackware, ROOT) and none of them worked. Our setup is really weird right now, we plan on re-wiring it soon. Here it is:

Code:

Cable Modem -> Voice Over IP &#40;Works like a NAT&#41;
                            |
                            |> This Computer &#40;w2k&#41; -> Hub &#40;LinkSys&#41;
                                                           |
                                                           |> My Computer

I tried doing DHCP, and after a "successful" try at getting the IP netcfg for eth0 is blank. When I staticaly add the IP (192.168.0.2) then it activates fine and the hub shows green for both computers. However, when I PING 192.168.0.1 (the IP of this computer) it can't find the host.

Any ideas on how to fix this? I'd greatly appreciate it.

What command did you use to set the IP? What is the output of /sbin/ifconfig?

**necrotic** · 06-17-2004

I used netcfg to set the IP.

ifconfig:

Code:

eth0      Link encap&#58;Ethernet  HWaddr 00&#58;A0&#58;CC&#58;30&#58;54&#58;43  
          inet addr&#58;192.168.0.2  Bcast&#58;192.168.0.255  Mask&#58;255.255.255.0

Did you add the default gateway? Post the output of route.

**necrotic** · 06-18-2004

I just added the default gateway, no effect.

Here's route:

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo

I may have figured out the problem. Our block is 192.168.102.x, I used 192.168.0.x. I installed w2k on the system and it worked, trying REd Hat now. I'll edit if it works. I feel really dumb, gah.

Edit: Well, it works as of now. The next test: move the network back to how it was wired before (I moved everything into one room and wired it better, but it can't all stay here)

Edit: Moved everything back, no luck. So it's something on this end (w2k).
