HELP!!! - Cannot detect eth0

Post by Flin » Sat, 21 Oct 1995 04:00:00

Have recompiled kernel with support for 3com509b ethernet card.  At boot up
messaged that "no such device", "network unreachable", etc.  Have tried
passing parameters (append = "eth0 = 10,0x300,0,0,eth0") with no effect.  Have
tried numerous permutations of this append.  My ethernet card is a 3Com509b at
base address 0x300  and IRQ 10.  There should be no other devices conflicting
with this IRQ.  Please help, I am headed for a bell tower with lots of

You didn't say if you have turned off Plug'n'Play option for this card (that is
the default).  If not, go into DOS and use Configuration disk that came with
card to disable P'n'P.

I also have a 3C509 card, LINUX has no problem recognizing the card, but I can't seem to connect to the

IFCONFIG returns the proper hardware address, IRQ and PORT as well as IP address, Netmask etc.

Snooping from another machine shows I'm sending out ARP packets, but ping never recieves a response.

netstat shows the following route table:

DESTINATION            GW             MASK    

I really don't know too much about routing, but my UNIX machines don't have all these zeros in them.  
Are they OK?

If so what else should I check?



1. Two eth0 detected. Help!

I'm running Redhat4.0.  I've installed two Cogent ethernet adapters
using the DE4X5 driver.  Upon boot, the system sees two eth0
devices - this is from /var/log/messages:

Feb 12 11:31:57 brian kernel: loading device 'eth0'...
Feb 12 11:31:57 brian kernel: eth0: DE434/5 at 0x6000
    (PCI bus 0, device 15), h/w address 00:00:92:91:24:f9,
Feb 12 11:31:57 brian kernel:       and requires IRQ10 (provided by PCI BIOS).

Feb 12 11:31:57 brian kernel: eth0: DE434/5 at 0x6100
    (PCI bus 0, device 16), h/w address 00:00:92:91:1a:18,
Feb 12 11:31:57 brian kernel:       and requires IRQ11 (provided by PCI BIOS).

ifconfig only sees one eth0 - the one at IRQ11.  My goal is to have ifconfig
see the adapters as eth0 & eth1.  I've tried various stings from the boot
prompt - ether=0,0,eth1 - and other strings specifiying the IRQ's and
addresses, but so far no luck.

Any suggestions gratefully appreciated.
