Another Newbie with network ping touble

tvreeland · 02-08-2004, 03:08 PM

First, let me apologize in advance for asking this YET again! Seems like it's a popular problem but nothing I've seen has resolved it for me.

I've just installed Mandrake 8.0 onto my machine (it's now triple-booting XP, 98 and Mandrake) -- Let's call it box #1.

I also have an XP machine that's running Internet Connection Sharing. I've got DirecWay Satelite internet (2-way) that uses a USB modem. Thus this machine has only 1 network card for the LAN. Let's call this box #2. It's at 192.168.0.1 and is named LORI. It's running under Windows Domain: MSHOME.

When box #1 is running WinXP or Win98 it can ping box #2 and box #2 can ping box #1. No problems with http, ftp, etc.

When box #1 is running linux I get nothing when trying to hit Box #2. I can ping 127.0.0.1, localhost, 192.168.0.225 (the IP for box #1) and linux (the name of box #1). However, I can't ping box #2 by IP or name. And box #2 can't ping box #1.

I've tried a variety of things and nothing has worked. To save time and questions, here's dumps of box #1 settings:

IFCONFIG -A:

What stands out to me is the Metric 0 in the last line. Should be 1

0 means that 192.168.0.1 can be reached in 0 hops...

tvreeland · 02-09-2004, 05:28 AM

Yah....

Do you think that Mandrake is autodetecting the network card incorrectly? I tried checking the Mandrake site for hardware info and couldn't find the card in their database : CNet PRO200WL PCI card...

Anybody have any other ideas?

michaelk · 02-09-2004, 08:59 AM

Your using 198.162.0.255 which is the broadcast IP address. Try changing to something else.

From ifconfig and mii-tool it looks like your ethernet card is configured and working.

tvreeland · 02-09-2004, 02:54 PM

Actually...I'm using 192.168.0.225 not 255 for the IP address

I've been looking at stuff regarding other folks having trouble with CNet PRO200WL network adapter. Two things that I've seen mentioned...

1) Compiling new drivers. This I've never done before but I just downloaded them. So I guess I'll reboot into Linux now and give it a try...

2) Disabling ACPI. I understand how it works in XP but don't have a clue in Linux!? I thought I saw something about needing to re-compile the whole kernel and re-install Linux. But then I saw something else about just disabling it at the boot prompt: acip=off. What is that all about and how could I give it a try?

Some help please!?!

coalquay404 · 02-09-2004, 03:03 PM

If you're using Mandrake, you've probably got LILO set up as your bootloader. As root, edit /etc/lilo.conf and locate the line with append="some stuff". You need to insert acpi=off in between the quotes. Reboot into this kernel and your acpi will be turned off. Check that out first and see if it helps.

bnice · 02-09-2004, 04:25 PM

at the command prompt type:

Code:

 

     /sbin/route add default gw 192.168.0.1 metric 1

then try to ping again

tvreeland · 02-10-2004, 06:20 AM

Thanks for the input coalquay and bnice. I've tried what both of you recommended with no success.

I tried the route command to add the metric (after removing the old one with 0) and nothing happened. I tried it with the autodetected drivers and the new ones I compiled.

I also tried adding the acpi=off into lilo.conf. I just left a space after the existing stuff inside the append="{stuff}" to make it look like append="{stuff} acpi=off". Is that correct or do I put commas or semicolons or something else as a seperator. If the space is correct, then that too has failed!

I'm not sure what else to do.....

bnice · 02-10-2004, 01:21 PM

append= looks good, whitespace is ok as long as the whole string is quoted,
e.g.

append="mem=96M hd=576,64,32 console=ttyS1,9600"

just for gits & shiggles:

post the output from:

Code:

cat /proc/interrupts

even on a quiet network there should be something in rx & tx sections of the output from ifconfig...

makes me wonder if it's a hardware / interrupt issue

here's my ifconfig for comparison:

root@Elvis:~# ifconfig

Now this is interesting...

/PROC/INTERRUPTS:

Code:

So...it that a conflict on IRQ 18?? And how could I fix it if that's the case?

it *shouldn't* be a problem to share an interrupt but...

I had an onboard audio device sharing an interrupt with a usb mouse, and the sound never worked until I plugged the mouse into a ps/2 adapter and removed usb support

Do you have USB devices installed?

You may also try setting irq 18 to isa / legacy in your BIOS, or assigning a specific (hopefully unused) IRQ to the slot your card is in....

tvreeland · 02-11-2004, 04:49 PM

I'm just totally at wits end with this.....SOOOOOO.....

I'm trying a different network card...see if that does anything....didn't really want to switch....but we'll see!

michaelk · 02-11-2004, 06:12 PM

Try adding noapic option to your bootloader.

tvreeland · 02-11-2004, 07:21 PM

All better.....

Swapped out my CNet NIC for a Linksys and everything's working fine...

Don't know what's up with the other one....maybe a newer version of Mandrake might support it but at this point I'm happy!!

Thanks for trying to help folks!!!
