[LARTC] HTB services & IP's

[Vlad Mihai]

Hello, 

I live in Romania where Internet is quite expensive for kids like me. 
We have managed to buy a 8/128 kbit (kilo bit) not kbps (kilo bytes).
It means that my ISP guarantees that the traffic won’t fall below 8kbit and can achieve 128kbit. 
I have a "SlackWare" Linux box that is used for NAT.
There are about 10 clients that will share the bandwidth.

I am very new to HTB and tc, so the answer for this question is a piece of cake for u ☺
I read an excellent article here: http://lartc.org/howto/lartc.cookbook.fullnat.intro.html

That script is somehow "service-focused", meaning that it filters the traffic based on services and ports.
Mine is "IP-focused", meaning that it filters the traffic based on IP’s in my LAN.

What I want is to "combine" these to types of scripts and have equal sharing among my clients and also prioritizing the traffic, 
as the article explains, based on services. What I had in mind so far was to create some leaf classes for each of my 8 clients, 
(I split the band in 8 pieces and after that I prioritize services on each of these pieces).
But this would make the script huge. 

I don’t know what to do… How can I mark (filter) the packets (with IPTables mangle) based on IP’s but also on services they need?


Thanking you in advance,
Vlad Mihai 



P.S.
BTW, I observed that the filtering works only for downloads, and is ignored for uploads....





Here is my script:

#!/bin/sh

TC=/sbin/tc
FILTER="$TC filter add dev $LAN_IFACE protocol ip parent 1:0 prio 1 u32 match ip"


$TC qdisc del dev $LAN_IFACE root >/dev/null 2>&1                                               # Delete previous root qdisc

$TC qdisc add dev $LAN_IFACE root handle 1: htb default 30                                      # root qdisc
