ethernet card doesn't light for lan, only net

ethernet card doesn't light for lan, only net

Post by Joshua Newm » Sun, 23 Feb 2003 10:35:30



I have a RH 7.2 with 2 linksys lne100tx.
I'm in the process of building a router firewall and have a temporary
setup.  

There are 2 nics: eth1 and eth0

eth1 goes out through my home linux router (a 3rd linux machine) and
has an ip of 192.168.0.11.  It is connected to the router and the nic
card light is
on.  It gets an internet connection just fine.  It works.

BUT

eth0 goes to a laptop (to simulate the future network client) and has
an ip of 10.0.0.1 (just for now while I configure it).  The nic card
has no light.  I can neither ping nor be pinged by the laptop
(ip-10.0.0.2, bcast 10.255.255.255, mask 255.255.255.255).  I know the
card works because i can switch the cables and I get a light.

I'm probably missing something totally obvious, so forgive me, but is
there something I'm missing that will let the ethernet get activated?
(both cards are of course seen on cat /proc/pci and
cat/proc/interrupts)

I'm stumped.  Any help?

Here is some info on the machine:

Do you have the correct type of cable?

Computer to switch/hub needs a straight cable and computer to computer needs
a cross-over cable (transmit and receive pairs crossed).

The lack of link light suggests that the physical connection does not work.

That appears to be a sure sign that you have an incorrect cable for
the laptop link (direct PC2PC should always use crossover cable).

1. LAN card doesn't work

My REALTEK 8029 won't initialize. I've configured the card in
linuxconf, but at boot-time linux is unable to configure the IP-address
for eth0. It's a PCI combo card on COAX. When I use my old ISA-ne2k,
all works well (DHCP and all)

The RTL8029 works, cause I use it in windows all the time. Linux
detects it, but can't find the DHCP server. Something to do with
UTP/BNC settings ?
