Trouble with LAN between W2k and Red Hat

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 (Works like a NAT)
                            |
                            |> This Computer (w2k) -> Hub (LinkSys)
                                                           |
                                                           |> 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.

ifconfig:

Code:

eth0      Link encap:Ethernet  HWaddr 00:A0:CC:30:54:43  
          inet addr:192.168.0.2  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:136 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          Interrupt:10 Base address:0xd800 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:111 errors:0 dropped:0 overruns:0 frame:0
          TX packets:111 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0

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

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

I've done a search on this forum and read through a few threads, none of them have a solution (that works for me at least).

I've found that using GUI config tool in X "redhat-config-network" works well to configure initial interfaces in redhat. I would also check your firewall rules arn't stopping things.

As a quick and nasty test to see if it is firewall, you could turn off your firewall on the box with "service iptables stop" then test.

Turn it back on with "service iptables start"

Hope this helps some.

We got it working, something on the w2k end. However, it takes >= 30 minutes for me to be able to use it at all. I have no idea why.
