Slack 9.1 only seeing loopback

[Dutch Mafia-boy.]

I am running Slackware 9.1 - just installed it actually. I previously had redhat 9 installed on this workstation - and its saw my network card interfaces as l0 and eth0.

Right now, Slack is only seeing l0 - no sign of eth0.

I switch from redhat because I was tired of being led by the hand.....so I'm looking forward to solving this problem (with your guided help).

Thanks.

Apparently, Slackware is not loading your network module.

What's the output of lspci?

And you will find that ethernet card related issues are one of the most popular questions posted here at JL. Looking/searching the forums will find you all sorts of troubleshooting tips (like the thread I just posted in before this one).

What does "ifconfig -a" show?

If it doesn't show eth0, try doing:

modprobe 3c59x

then try the ifconfig -a again.

Dutch Mafia-boy.. post the results as serz suggested from "lspci"
unless you already know your card make and model.
If you do..go to /etc/rc.d/rc.modules to see if it is listed then uncomment it for initiation upon boot. If it's not there you have to add it, but first you need to determine which one by "lspci"

here is the portion in lspci referring to my network card:

Ethernet Controller: 3Com Corporation 3c905B 100BAseTX [cyclone] (Rev 30).

I can also see it being detected on bootup.......so I would say the module is being loaded....however, when I run ifconfig, I still only see lo.

What else should I try?

Check through /etc/rc.d/rc.modules and uncomment the portion under network cards referring to your network card.

The line should be:

/sbin/modproble 3c59x

3com 3c905 cards use the 3c59x module.

Thanks for the reply. I did this, rebooted and still am not getting an eth0. In Redhat, you would just type :

service network restart

to restart the network services - how do you do the same thing in slack?

[rbrimhall]

cd /etc/rc.d

as root

sh rc.inet1 restart

You may need to check out inet1.conf too...

OK....that's good to know for future reference, but I am still having trouble seeing my network card....

[Daedrus]

try running modprobe 3c59x and see if you get an error. Run this as root.

I did this already - and no errors came up.

[Daedrus]

after modprobe:

ifconfig eth0 up

or

dhcpd eth0

after modprobe:
ifconfig eth0 up

or

dhcpd eth0


After running modprobe - and then running ifconfig eth0 up,it gives me an error saying - "No such device".....which is understandable since eth0 doesn't exist in the first place.

This is a brand new installation of slack 9.1 with a quality network card in it...

I've removed the # in front of 3c59x in /etc/rc.d/rc.modules and restarted...

I've manually run modprobe 3c59x and it returns no error.

I've seen the system recongnize/initialize the 3com card on startup.....

frustrating.....

[Daedrus]

Okay, since you know that the system is recognizing the card on startup, have you tried running netconfig and setting up a static ip address for the card?

After running modprobe - run "lsmod" to see if the module loaded. What's the staus of you Plug n Play setting in your bios?

I ran "lsmod" and did see that the module was loaded, but was unused. I rebooted, and enabled my PnP setting in my bios, reboted and I had an eth0! Yeah!

Thanks for all your help guys.
