no network after fresh Slack 9 install

I have a little trouble getting my network to work.

-P200 (It's a "test" box.)
-3com Etherlink III (3c509)
-Linksys 4 Port Cable/DSL Router as the gateway (
-Static IP address ( (no dhcp)
-Nameserver: running bind locally

eth0 is detected
eth1 also detected (? guessing this is for loopback only from rc.inet1

I can only ping myself. I'm not sure if this is a hardware issue or a bind issue. Given that the card is detected and line 2 lights up on my Linksys, I'm inclined to think it's a bind issue.

I had to rebuild with a fresh install of Slack 9. Previous setup was Slack 8 upgraded to current (the hard way). I completely blew away the / folder. (I did back up the /etc folder to another partition.)

Any help/ideas would be appreciated.

Try typing (in the console or terminal)

ifconfig -a

If that yields your ehternet card as eth0 and your IP address is correct, you should be in business.
Also, if you ever choose to go with a dhcp client, you can type dhcpcd and everything will set itself up automatically (the easier option that I used).

Also, if your ehternet card happened to be detected as eth1, make sure that you add that paramneter when you ping (I don't remember the paramneter at the moment).

Thanks, rcrules.

Here's what 'ifconfig -a' shows:

eth0 Link encap:Ethernet HWaddr 00:00:08:00:19:00
inet addr: Bcast: Mask:
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:0 (0.0 b) TX bytes:378 (378.0 b)
Interrupt:5 Base address:0x220

eth1 Link encap:Ethernet HWaddr 00:60:08:E4:198
RX packets:0 errors:0 dropped:0 overruns:2295 frame:0
TX packets:2295 errors:0 dropped:0 overruns:0 carrier:6885
collisions:2295 txqueuelen:100
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:10 Base address:0x300

lo Link encap:Local Loopback
inet addr: Mask:
RX packets:7 errors:0 dropped:0 overruns:0 frame:0
TX packets:7 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:784 (784.0 b) TX bytes:784 (784.0 b)

I had copied my rc.netdevice from the old etc dir (and made sure the line in rc.modules was commented. It has only the line '/sbin/modprobe 3c509'. I'm a little confused why there is both a eth0 and eth1. My rc.inet1 after running netconfig is identical to the old one.

/proc/interrupts shows eth0 as using IRQ 5
/proc/ioports has 2 related entries:
0220-022f : 3c509 PnP
0300-030f : 3c509

I've tried pinging with the I (capital i) parameter without success. Strangely, that option isn't described on the man page, so trying different values, the results were as follows:

0x220,0x310,220,310: cannot set multicast source interface: Cannot assign requested address
eth0,eth1: bad interface address

I can't use dhcp only because I want to host my website on this box again, which due to the linksys & port forwarding, requires a static IP.

according to your ifconfig output, this boc has TWO network card, or something is really bad.
try this :
"ifconfig eth1" then try to ping.
Are you sure your box doesn't have a nother network card, onboard or something?

Thanks for your help guys. I think I found the problem. (Now just to fix it...)

I definately only have 1 NIC in this computer. For some reason, however, it seems like the box was confusing my internal ZIP drive with another NIC. After a halt, unplugging the power on the ZIP, and powering on again, only eth0 shows up and network is up.

I'm guessing that they both use IRQ 5 by default, and (I thought) that IRQ was reserved for the EISA card in the BIOS, but that didn't seem to make a difference. (?)

...but that's another issue. For now, I'm satisfied to have networking working.
