Hi Martin,
I tried the suggested script, but it doesn't
seem to be working,
I adapted it along the lines of
#include "fields.tc"
#include "ports.tc"
#define MY_PDA 10.1.1.8
#define MY_LAPTOP 10.1.1.20
#define INTERFACE eth1
dev INTERFACE {
egress{
class ( $video ) if tcp_sport == 1755 ip_dst == MY_LAPTOP
;
class ( $video ) if tcp_sport == 554 ip_dst == MY_LAPTOP
;
class ( $video ) if udp_sport == 1755 ip_dst == MY_LAPTOP
;
class ( $video ) if udp_sport == 554 ip_dst == MY_LAPTOP
;
class ( $other ) if 1;
htb() {
class ( rate 3500kbps, ceil 3500kbps ) {
$video = class ( rate 30kbps, ceil 30kbps ) { sfq; } ;
$laptop = class ( rate 50kbps, ceil 1500kbps ) { sfq; } ;
$pda = class ( rate 50kbps, ceil 50kbps ) { sfq; } ;
$other = class ( rate 150kbps, ceil 150kbps ) { sfq; } ;
}
}
}
}
The BW of the video stream on the MY_LAPTOP
device is roughly 150 kbps, suggesting that is has not been pick up by the
criteria. I use this:
#!/bin/sh
IPTABLES=/sbin/iptables
# ALL LINES BELOW ARE NAT ROUTING
# flush out all old rules
$IPTABLES -F -t nat
# turn on NAT (IP MASQ for outgoing packets)
$IPTABLES -A POSTROUTING -t nat -o eth0 -j MASQUERADE
# enable IP Forwarding (of incoming packets)
echo 1 /proc/sys/net/ipv4/ip_forward
route add default gw 10.0.0.1
# WIRELESS CARD SETUP
iwconfig eth1 mode ad-hoc
iwconfig eth1 essid BKR_FYP
To setup my masqueradingI'm puzzled, can you
suggest a way to start debuggin this?Again many
thanks,Barry.

Eth0 is connected to a private network which has on it a Media Server:
streaming rtsp files Eth1 is a wireless card on an ad-hoc network with:
a laptop, a pda, and a desktop.Understood.: The idea is then
to imitate different QoS levels to the different: devices, the idea
being that the pda shouldn't need as much bw as the: desktop etc. So the
three devices get dhcp leases dependant on their: mac address, and then
their ip address is used to identify them and: (hopefully) tc will then
allow me to create sfqs for each device.Understood.: I have
tested the devices without any shaping, and also with shaping of: all
rtsp/mms protocol based traffic to the 50kb class. This works and: has
been confirmed by the stats on the media client, it can be quite:
clearly seen any way the video starts to jump and
stutter.OK.: However I have been unable to get the shaping
to only occur on one: device, maybe the laptop for example whose address
is 10.1.1.10I don't really understand what you mean
here.Have you tried creating separate classes for each
device?sfq doesn't do any shapinghtb (classes) perform
shapingSo, here's a fractured/partial tcng config:#define
MY_PDA 10.1.1.8#define MY_LAPTOP 10.1.1.10class ( $video
) if tcp_sport == PORT_RTSP ip_dst == MY_LAPTOP ;class (
$laptop ) if ip_dst == MY_LAPTOP ;class ( $pda) if
ip_dst == MY_PDA ;class ( $other) if 1 ;htb() {class
( rate 3500kbps, ceil 3500kbps ) {$video = class ( rate 50kbps, ceil
50kbps ) { sfq; } ;$laptop = class ( rate 50kbps, ceil 1500kbps ) { sfq;
} ;$pda = class ( rate 50kbps, ceil 50kbps ) { sfq; } ;$other =
class ( rate 200kbps, ceil 3500kbps ) { sfq; } ;}}I can't
tell if this does what you'd like, but maybe it does.Good
