tcng/tc setup
Hi all,
Can someone please help with a tcng setup? I have played with tc and tcng in
the past, and now would like to get some serious rules in place. However, I
have a difficulty in setting them up.
My setup is as follows:
One machine working as a firewall:
eth0 is the interface connected to a 512K DSL line
eth1 is connected to a LAN
eth2 is connected to another LAN, a bit like a DMZ

Simple HTB setup with tcng
Hello all,
I am trying to set up a simple htb based system, where packets with
source ip 10.0.0.1 should have their own class.
I plan to use tcng to set it up easier.
Is there something wrong in my tcng file ?
~/tcng$ cat htb
/*
*/
#include "fields.tc"
#include "ports.tc"
dev eth0 {
htb ( ) {
class ( rate 600kbps, ceil 600kbps )

TCNG HTB priority and bandwidth
Hi,
I have several users on the lanside each allocated separate IP addresses.
I need to allocate th traffic to each IP addresses certain portion of
total uplink.
Say, 192.168.0.2 rate 128kbps, ceil 128kbps.
192.168.0.3 rate 65kbps, ceil 128kbps
129.168.0.4 rate 64kbps, ceil 64kbps.
and so on....
Also, for each user i would like to prioritize the traffic within the
allocated bandwidth.

TC-ng questions/problems
Hi all,
We have 2 class C networks that are connected by a Linux router with the internet. We want to apply traffic control (bandwidth control). For that we wrote the tcc script below. We have 2 problems:
1. To establish a 2 megagit download we must actually set the value to 2500kbps. Is there a possible reason for that?
2. If we enable the WAN device we get very hight ping times (they change

lan is on eth1 and on eth0 I''ve the dsl connection (1.2 Mbit / 256 kbit)
I need to limit the bandwith towards lan and I''ve thought at HTB and
tcng. I write the script belove. I want limit the p2p and ftp (ssh and

tcng and ip_len
I can''t seem to match packets less than 512 bytes:
class( <$bulk> )
if tcp_dport == 81 && !( ip_len & 0xfe00 )
;
or
if tcp_dport == 81 && ip_len < 512
Both rules match any packet I send to port 81, even when the total IP length
is much greater than 512 bytes:
class htb 2:4 parent 2:1 leaf 5: prio 1 rate 8000bps ceil 24000bps burst 6Kb

TCNG HTB Branching the class not working. (bug or what)
Hi,
I am new to traffic control in linux. However, i have able to grab many
new knowledge in recent days. I find tcng somewhat easy to use (although
lack proper doc. of its usage).
I want to control traffic of several IP Addresses connected to my LANSIDE.
What I want is , i want to separate certain bandwidth to all my clients.

tcng ingress policing question

I started playing with tcng to generate my tc rules, but I have some

tcng configuration question??
Greetings all,
OK - just started playing around with traffic shaping - have imq and htb
and (I think) everything else I need in the kernel and running well. My
initial lab task was to protect a H.323 session over a simulated half T1
while adding bulk traffic - got that accomplished after slogging through
learning tc and decided in short order that a more intuitive interface

PPPoE and shaping
Hi all,
I have a little problem with my home-made slackware linux server.
Here is the scenario:
1. I have a local wifi network
2. my server do masquerading and exit in internet via a PPPoE connection
Goals:
1. not use SQUID
2. shaping the traffic with classes
3. emule connection must have minimum priority and a band-limit of
10KBytes/s in uplink (server--->internet)
Any idea?
Thx,

I''ve been trying to shape the bittorrent traffic (on my external interface,

TCNG issue - parent class restrictions are not honored
Hi,
I''ve been migrating an existing htb-based traffic shaper from a
hideous (I''m allowed to call it that - I wrote the damn atrocity myself)
tc shell script into a TCNG configuration file, and after a few false
starts I think I managed to get the syntax right.
However, during tests it looks like some of the tiers aren''t passing
their restrictions on to lower levels.
