Fedora Networking issue...It's driving me MAD!!


Hi everyone...I'm losing my mind...

Here is the situation...I've been using RH since 5.1 and I know my way around...somewhat...I recently installed Fedora Core 2 on my machine and I can't get the internal network to work correctly.

The Server is a generic hardware system P4, On Board NIC VIA...etc..

It's acting as a router...when it's acting at all. if Config and Route listed at the bottom of this post. When I first installed I had (2) 3C905TX cards in the server along with the On Board NIC

eth0 (onboard) Via chipset -- DHCP enabled Connected to Switch, which is connected to cable modem -- This works fine
eth1 (3C905TX) -- Internal LAN 192.168.1.1 connected to switch, connected to internal LAN
eth2 (3C905TX) -- Internal LAN 192.168.1.1 connected to switch, connected to internal LAN

The internal network is all on 192.168.1.x, the reference client is WinXP at 192.168.1.2

When I installed I noticed that I couldn't ping the internal network...nothing came back...

I switched one of the 3Com cards for a Kingston Card...and things worked until i rebooted...then they stopped working...

I took out all of the cards...deleted their configs...in the GUI tool and restored only the Kingston card and the onboard nic...didn't work...

I've tried every combination of card, that I can think of and ran mii-tool

eth0: negotiated 100baseTx-FD flow-control, link ok
eth2: negotiated 100baseTx-FD, link ok

In the above case, only the Kingston card and the onboard are installed.

I can't figure this out...what am I missing? I turned IPV6 off.

/etc/sysconfig/networking/devices/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
HWADDR=00:0a:e6:e9:dc:b5
USERCTL=yes
PEERDNS=yes
TYPE=Ethernet
IPV6INIT=no

/etc/sysconfig/networking/devices/ifcfg-eth2
DEVICE=eth2
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.1.1
NETMASK=255.255.255.0
HWADDR=00:C0:F0:30:0E:A6
USERCTL=no
PEERDNS=no
TYPE=Ethernet
IPV6INIT=no


Any help would be appreciated.

It all looks right to me - try a Knoppix boot to eliminate the possibility of kernel badness, and if that fails maybe a wiring problem. Dodgy network cables can produce some weird glitches.

Not much help there but mainly I just wanted to say - I feel your pain.
