Re: eth1 is dead

you may also want to verify the contents of /etc/sysconfig/network-scripts/ifcfg-eth1, you can get away with just having

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.16.30.25
NETMASK=255.255.0.0

Hi, all.  I'm feeling REALLY dense right now.  I hope this is not a
"Duh!" kind of thing.

I have a Compaq desktop, D500, with 2 GHz P4, 512 Mb, etc. and an
onboard Intel NIC.  What I want to do is turn it inot a backup/test
firewall system.  So, I bought an Intel 100 Pro server NIC and installed
it.  When I install Fedora from the CD's all seems fine.  It finds the
NICs, assigns IP addresses, routes, etc. and everything is happy.

Until you try to use eth1.

I can ping the address just fine, but I cannot ping anything out of
that interface.  The other interface is fully operational.  If I ping
the interface from a known functional system, I get no returns.  Not
even an ARP response.

Here's what I've tried:

I tried three other NIC's, both Intel and 3Com.  I tried moving
interrupts around.  I swapped cables, switches, IP numbers, brands of
coffee.  (Hey, I was desperate!)

I tried a different machine, even tried a Dell GX115.

I tried a different driver, updated kernel, turning off everything in
the BIOS that a firewall wouldn't need (LPT, COMs, USB, etc.)

Nothing worked.  It acts like the NIC doesn't interrupt the processor.

Here are some sample outputs in hopes someone has seen this before.  I
tried Googling the symptoms and didn't see anything relevant.  Let me
know if you need to see anything else.

TIA!
