testing ethernet connection

[ezjab]

Hi,

I have a new PC where I have installed Red Hat Fedora Core 1.
Among other things, my ethernet interface is not working.

My other LAN PCs are working with my current router so I know
it is working properly. I know I have a 'live' ethernet cable
because I'm switching it from my laptop to the new PC to test.
I checked the BIOS and onboard LAN support is enabled.

I noticed some error messages when booting but they scrolled
by quickly. When I look in /var/log/messages, I find this
error message, but I don't know the impact:

Dec 2 11:11:10 jjapc9 modprobe: FATAL: Could not load
/lib/modules/2.6.8.1-10mdk/modules.dep: No such file
or directory
There are another 300 lines, give or take, that have similar
message related to modprobe. This looks suspicious to me.
Since the floppy disk drive and ethernet interface are not
working, I cannot get the log messages off the PC to include
in this post.

If I enter:

ping 192.168.1.101

on a PC already working on the LAN, I get back the expected
output.

If I enter the same command on the new PC, I get back the
message:

connect: Network is unreachable



My assumption is that 'ping' is a very low level command
and that interfaces directly to a s/w driver that interacts
with the ethernet hardware. If it is not working, then
I must have a BIOS or hardware problem. Is there anything
in Linux that needs to be configured to make ping work?

I have talked to tech support of the motherboard manufacturer
and was told that I would need a linux driver for the
onboard device which turns out to be from Marvell Technology
and is a Yukon 88E8001 device. I've looked at their website
and there is a driver, but I have not downloaded it yet.

In the meantime, I have installed an ethernet PCI card into
the PC. When I reboot and try to connect to the ethernet
through the PCI card, I still get:

connect: Network is unreachable

when I try to ping the router. So, I still need help to get
an ethernet connection working.

Please stop top posting. I wouldn;t normally reply to someone who
hasn't managed that, and neither will many others in here.

My Asus MB uses the yukon gigabit miniport driver - works fine. You
may want to do a bit more research, though. The Yukon driver is
included in Suse - I didn't have to download anything. Why wasn't
yours detected?

It looks like the kernel can't load the proper module, that's why you have
those 'modprobe' errors. Check that path to see if the file is present,
also read the man pages for 'modprobe', 'insmod', 'rmmod', 'lsmod'. There
will be information to help you solve the problem.

^^^^^^^^^^^^^

FC1 was a 2.4.x kernel (2.4.20, I believe) and probable doesn't like
a 2.6.8-1 module, from Mandrake (mdk)

That would be wise

Well, but it also helps if the warning/error messages are read.
