[LARTC] Networking options + patch

[sun reflex4]

Hi all,
I have 3 small questions:

1)In the /usr/src/linux/.config : there is the option "m", I know y and n, 
but is m?

2)After I change there some values, do I need to compile anything? or just 
save the file?

3)I want to patch my SuSE 8.1 with HTB, i got the file htb2.diff, but where 
should I place it to call "patch -p1 < filename.diff" ??

Thanx for ur help



              <= sunreflex4 =>

m is for module.  That's a kernel extention that can be loaded at run time.

You have to recompile the kernel and the modules and boot from the new 
compiled kernel.

Anywhere you want.  As long as you run the command from /usr/src/linux.

It seems to me that this is your first kernel compile.  I suggest you read the 
kernel HOWTO because it's possible that you make an error and leave your box 
unbootlable.

thanx for the fast reply, and i have just printed the "Kernel HOWTO", to 
read it carefully before doing anything. In respect to "m", should i leave 
it in the .config, or replace it with "y" to enable e.g. CBQ or other 
things?

bye

There are also other ways for configuring the kernel.  Try to run
make menuconfig
in /usr/scr/linux.

Compiling an option as module or not is your choice.  If you compile it as a 
module and you change something in the source, you can remove the module and 
reload the modified module.  I sometimes use it to test a change in the htb 
qdisc.  I also have all qos options compiled as module.  I don't use them so 
I don't have them in the kernel.  But if I want to use them to test 
something, there are loaded by the kernel.

Be aware, compiling and booting from your own kernel is a real challenge if 
it's your first time.  Be sure you ALWAYS have a good kernel so you can go 
back to your old situation.  Or try make bzdisk.  It will create the new 
kernel and place it on a floppy so you can boot from it.  If boot 
succesfully, you can configure your boot loader to use it.

I also suggest using grub as boot loader and not lilo.  Grub is "filesystem 
aware" so it can see the kernel in the file system.  If you use lilo, you 
have to update the bootloader each time you create a new kernel.  Debian has 
a script that finds all kernels that can be used and configures grub 
accordingly.
