Re-configure After New Kernel Install

alienzero · 06-23-2004, 07:24 AM

Hi all. I just installed a new kernel image and it seems as though I need to re-configure my network settings.
As you know, when you first install Debian, it prompts you with configuration questions about your hardware and internet connection, etc. When it came to configuring my connection, I said to just let the DHCP server do it for me. This works great, but I need to know how to do that again for my new kernel? Is there a command to run or a config file I edit? The new kernel is 2.6.6-1-k7 from Debian.org running on Sarge. Thanks!

b0uncer · 06-23-2004, 07:39 AM

umm...as far as I know, the options you chose while installing were saved as configuration files or something...like resolv.conf, hosts.conf etc. etc. etc. and the kernel's job is to provide the "tools" for doing the actual work. I haven't had any need to do any reconfiguration after kernel updates, and I don't think you should neither have...are you sure you enabled your network hardware's "drivers" in your kernel (built-in/modules)?

what exactly is it that is not working or tells that you need to reconfigure? if it's a non-working ethernet, then I'd guess you forgot something from your kernel...

altough I can be wrong on this, but at least I have never ever reconfigured network after updating kernel...I've just checked that the modules etc. I need are in the kernel and the existing saved config has worked.

Well as I stated before, I just installed a new kernel image. I have not messed with a kernel at all before so I don't really know what I'm doing

But LQ is helping alot.
I know that the connection to the outside world is not working because I simply type 'apt-get update' and it returns "failed to connect..."
It is probably a module thing. I don't know how to mess with those though. How would I go about checking the kernel module, which one, and how? Thanks!

i have use apt-get to upgrade kernel images and never had to worry about my network connection....i t always works without any additional configuration...

Ok. What are you exact steps in doing this? I'd like to know. BTW, this thread is a continuation from http://www.linuxquestions.org/questi...hreadid=195323

first of all.....what boot loader are you using.....Lilo or Grub...or 3d party?
on my system i use grub and when i apt-get a new image ..it automatically takes care of grub...

ok...

define your sources.list
as root
apt-setup

here you can pick out with source location you wish to use

that being done...

as root

apt-get install kernel-image <the image # you wish to install>
simple
after all done....reboot

alienzero · 06-23-2004, 05:56 PM

OK, well I use lilo, and I just want to use the kernel-image-2.6.6-1-k7-smp from Debian.org
How would I set up my sources list to get that? Maybe I have it already. Here's my current sources.list:

Code:

alienzero · 06-23-2004, 06:02 PM

Hmm, nevermind that last post. I just attempted 'apt-get install kernel-image-2.6.6-1-k7-smp' and it's now installing

I'll let you know how it goes afterward.

blanks · 06-23-2004, 06:06 PM

Is the kernel detecting your nic? What's the dmesg output? If your nic is detected, what does ifconfig say?

utanja · 06-23-2004, 08:14 PM

this is my sources.list

deb http://ftp.us.debian.org/debian/ testing main
deb-src http://ftp.us.debian.org/debian/ testing main

deb http://security.debian.org/ stable/updates main

i have no listing for stable or sid...

alienzero · 06-23-2004, 08:36 PM

OK, I have the SMP kernel installed fine. I had to manually tweak lilo.conf but that's ok. But the connection is still not there.
I'm really wondering about the modules configured with these kernel images from Debian.org. When I mounted the floppy drive in order to get dmesg info from my server to this computer, I think it installed the kernel mount module right then, or something.
Anyway, demsg output:

I don't see your nic detected anywhere... You should have a line like:

eth0: <nic brand> <mac addr> <lots of other stuff>...

You might try compiling these drivers directly into the kernel - i.e. not as a module

alienzero · 06-24-2004, 12:49 PM

All I did was install the kernel image and boot fro it. I don't know anything about a module. It's probably not even there. When I initialy installed Debian I let it configure my NiC via DHCP. This worked great.
Is there any way I can have it configure again? Or how do I compile the driver directly into the kernel? My board is the Tyan Tiger MPX (S2466-4M) with onboard 3Com 3C920 LAN controller.

alienzero · 06-24-2004, 12:49 PM

I wonder if I need to configure the new kernel somehow? Maybe there are no moduels loaded?
I used "configure network via DHCP/BOOTP" when I first installed.

alienzero · 06-24-2004, 07:23 PM

I found this page: http://www.debian.org/doc/FAQ/ch-kernel.en.html
Near the bottom under "9.4 What special provisions does Debian provide to deal with modules?" it has some files that deal with the modules for the kernel. I checked my /etc/modules file and there is only one entry: af_packet
I'm assuming that this means there are no other modules installed?
I also tried running the program 'modconf'. The only menu entry it gave me was to exit the program.
