internet settings

shocker-z · 04-09-2005, 01:33 PM

Hi I have 2 NIC's: ADMtek|ADM983 & Realtek|RTL-8139
and I can't get either to connect to the internet I’m using a router 192.168.1.1 as my gateway and DNS but its still not working and every time i restart, the DNS changes to 127.0.0.1, I’ve tried this with both card and I’ve also tried setting them to DHCP but no luck what so ever! Both cards worked when I had Debian on with a 2.2 kernel but seem to have problems with anything above 2.2 kernels.

setting card IP as 192.168.1.4
running Mandrake 10.1

Any help will be greatly appreciated

hi there

try this
for one NIC
assign static IP address
with gateway as that of ur router and dns server the same
and they try accessing the internet ,and if it still does not work then again give me the O/P of the above commands

regards

shocker-z · 04-10-2005, 08:22 AM

ive tryed that, and thats what messages i get, thats what i donbt undertsand, ive tryed it on both crads, doing it wiht one and removing the other for both static and DHCP and neither ways are working! yet both cards are detected and i know the cable is working because all lights are on both router and card and all works fine in 2.2 kernel. :S
any ideas?

thanx
liam

masand · 04-10-2005, 02:13 PM

assign static ip address then run

route add default gw 192.168.1.1

and check that u have 192.168.1.1 in /etc/resolv.conf

and if it still doe snot work then post the O/P of

ifconfig

and route -n

regards

Hi

Looks like the modules are not being loaded for your network card(s)

We will try using the realtek card (same as in my desktop)

You can check if the module is loaded with

Code:

lspci | grep 8139too

if it returns nothing, the module is not loaded.

If not, type (as root)

Code:

modprobe 8139too

which will try to load it for you - you should get some feedback.

To make this permanent, stick the following in /etc/modprobe.conf :

Code:

alias eth0 8139too

and comment out anything else with eth0 or eth1 in it by putting a # at the beginning of the line. This should enable the driver module to load on booting. You need to log on as root for this.

You may find it all works after a reboot, but if not check out my Mandrake simple net setup howto at www.iwpcs.co.uk/simple_net_setup.html. If you still have problems, the bottom of the page has a few commands you can post the output of here for further help. Add lspci to this list.

Good luck!
Chris

i did
modprobe 8139too
and received nothing on the screen it just accepted it, reinstalled mandrake to clkear all drivers and everything and followed that site and still not working im now getting
Bringing up interface eth0... failed
i have tryed a bran new network card and that comes up with the same error
ive added 8139too to /etc/modprobe.preload but still not working
now comes up with failed to bring up eth0

any ideas?

masand · 04-12-2005, 10:58 PM

post what u have in

/etc/sysconfig/network-scripts/ifcfg-eth0

iwpcs · 04-13-2005, 01:36 AM

Ok

One thing at a time...

'failed to bring up eth0' messages at boot time is not uncommon and does not always spell doom.

Not printing anything to the screen is usually a good thing in the Linux world - it usually means it worked!

So type modprobe 8139too again.

Then type lsmod - if there is 8139too listed, then the module is inserted OK. If not, we need to look further in to it.

Put the alias line into /etc/modprobe.conf. I find It best to not put anything in /etc/modprobe.preload

Any chance of removing the second network card, or disabling it in the BIOS if it's onboard?

Don't use any of the Mandrake wizards.

Don't keep re-installing.

You didn't follow the instructions in the link - you haven't posted the list of command results at the end!

Add lsmod to this. We need these to help.

Don't give up!
Chris

shocker-z · 04-13-2005, 03:51 PM

ok i have just the realtek card in now.
i did

Code:

modprobe 8139too

then

Code:

 lsmod | grep 8139too

and that returned

Code:

8139too   20928   0
mii   4224   1   8139too

i then went to add line: alias eth0 8139too but it was already there
i then did

Code:

lspci | grep 8139too

and it returned

Code:

00:0c.0 Thernet Controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

restarted the system and still coming up that it failed

any more sugestions?

sorry for being such a pain, i did follow every single instruction on that page, i was very tired and kinda just didnt mention everything, sorry for that.

iwpcs · 04-13-2005, 04:45 PM

The system can see the card - that's good.

Remember, don't worry too much about the failed message at the moment.

If you do an lsmod | grep 8139too after the reboot, without typing the modprobe command, do you get the same result?

If so, the module is being loaded OK and we just need to check your settings, so post the output of :

ifconfig

route -n

and the contents of /etc/sysconfig/network-scripts/ifcfg-eth0

and we'll see what we can do.

yep "lsmod | grep 8139too" is returning the same results

"ifup eth0" returns

Code:

what next mate? any chance of talking over msn one night or somthing? might be able to get it sorted bit quicker, else we could use irc if your into that? irun a network so that would be fine.

thanx mate

iwpcs · 04-14-2005, 03:29 AM

Hello again

I don't have any sort of chat stuff set up, but perhaps I should...

I wonder if the onBOOT in /etc/sysconfig/network-scripts/ifcfg-eth0 needs to be in all UPPER CASE and is causing the SIOCSIFFLAGS problem? Just guessing. Try changing it and rebooting, assuming it was not just a typo in the post.

Quote:

Sorry, I should have been clearer - I meant the same results as
8139too 20928 0
mii 4224 1 8139too

Is that what you mean too - what you are getting after a reboot, without doing anything else?

If so, the modules are being loaded - the interface should work, so your next step is to try to bring the interface up manually:

Code:

ifconfig eth0 192.168.1.4 up

then type ifconfig to see if it worked - post the output.

If the modules are not being loaded. Have a look in the logs for any messages.
