Hi, i have here a little problem, in my desktop are 3 NIC's 1- internet 2- LAN
when im starting my fedora 7 the network led's is not turned on on both LAN interfaces, but network-config says that those connections are enabled and thats not all: my friends on LAN usink windows and the windows network manager says that "the cable is plugged out" but the cable is REALY plugged in. When im starting the windows, after fiew seconds the led's on LAN NIC's turns on, and network is up. On earlier fedora releases ive not experienced this problem...

now using F7 2.22.9 kernel i686

Yes i have internet on eth2 (nVidia) but lan nics (eth0, eth1) seems to be not working on linux, first of all i need to set these interfaces up, then i'll make a bridge with bridge-utils and share internet.

As i sayed, eth0 and eth1 not working on F-7, when im restarting to Win XP it works normally, and the internet is shared.
That where the problem is, why these interfaces not working on linux???





Also ive noticed the message, when linux starts:
"PCI:BIOS BUG: MCFG area at f0000000 is not E820-reserved
PCI: Not using MMCONFIG"

the boot option "pci=nommconf" helps to rid of this message, but no network led on my neibor PC flashes on, when the interface is bringet up...

Are you trying to run the cable directly from one machine's NIC to another machine's?

YES, it looks like that:


internet
|
|
[eth2]
[My PC][eth0]--------[other PC_1]
[eth1]
|
|
|
[other PC_2]

You may require a crossover cable (not if you are using GigE).

That's where I was headed with that. If you can't find one, you can make one by cutting a short cable and connecting the greens from one half to the oranges of the other half, keeping the solids to solids and stripes to stripes.
