[Techtalk] QoS traffic shaping in 2.4.26

[Elwing]

So, I've got myself a VoIP phone, and I want to implement traffic 
shaping on my firewall.  It's running a custom kernel, but the base is 
debian stable.

Following bits and pieces of documentation I've found [1], I've 
attempted to compile a kernel.  Apparently, I don't need any kind of 
patch to 2.4.26 to support HTB queues.  So, I've got myself a stock 
kernel, with everything under Network Options -> QoS and Fair Queueing 
selected as a module (unless it's only allowed as part of the kernel).

I can compile the kernel and modules fine, but when the modules try to 
load, I get all kinds of unresolved symbols. [2]

Do I really need some kind of patch?  Am I completely on the wrong track?

My ultimate goal is to give VoIP traffic as much bandwidth as it wants, 
P2P/bittorrent uploading only if nothing else is using the connection.
So, I was going to use four queues: one for VoIP traffic (always to and 
from one specific host), one for interactive traffic (SSH, telnet, 
etc..) one for "other" such as HTTP, SMTP, etc..  and the final queue 
for P2P/bittorrent traffic.
I was going to use the tc command line (I found some decent example 
scripts), but is there another way to do this?
I'd prefer not moving up to the 2.6 kernel if possible, but I'll 
consider it with a pressing reason why I should.

Thanks!

are the same):
