Hi, I have simple question about Skype. What are the methods of selecting packets which belongs to Skype?? I know about 7layer but I don''t belive that is only way. Is 7layer realy good and stable solution for routers which must handle more than 1000 users ? Thanks in advance Pozdrawiam Szymon Turkiewicz

Hello, Sorry for the many Ccs, but I hope to reach all parties involved. I want to do traffic shaping with NAT and I wanted to do it with IFB instead of IMQ [1]. I tried a lot of things but now I am stuck (and maybe confused). The setup: eth0 eth1 WAN/(Internet) <-> Linux Router <-> LAN Linux router: - does NAT for the LANs - runs local processes

Hi I''ve a stupid question. How can I shape upload using IMQ? Instead of putting a rule in iptables in PREROUTING should i use POSTROUTING? And another question is, can I make routing rule based on ip addresses assigned by iptables to an imq device? The idea is, let''s say i have some rules in iptables like: -t mangle -A PREROUTING -s 192.168.0.0/16 -j IMQ --todev 0 Can i route

Hello, Some time ago I''ve read somewhere that local traffic in IMQ could hung up the whole system but it was corrected long time ago. So I was very surprised yesterday when it occurred not true. While testing IMQ I''ve observed for some time that - if you tag some local traffic with iptables both in pre- and postrouting - kernel is hunging up. It is happening quite quick with

Hello there! I was reading this archive: http://mailman.ds9a.nl/pipermail/lartc/2002q3/004725.html It was almost two years ago when Patrick wrote a patch to switch IMQ with nat in PREROUTING chain... From www.linuximq.org I''ve downloaded newset IMQ driver for 2.4.26 and what can i see? The line that Patrick changed in that patch is still as it was in previous relases. Are there

Hi all, I want to divide the incoming traffic between what should go to the firewall and what should be forwarded to the local network behind it. I started with the IMQ example config, but added an extra htb class right below "10:1" to get the two sfq''s to borrow each other''s bandwidth. However, I can''t figure out how to set the two marks. According to this

Hi all, my IMQ device works OK (thanks to Andy Furniss), but now I''ve problems to attach the traffic in the qdisc''s. This is my conf: ----------------------------------------------------------------------- INET | |eth0 300Kbps ROUTER (NAT) |eth1 | LAN ----------------------------------------------------------------------- MAX=300 tc qdisc add dev imq0 root handle 1: htb

Hello I have a server with a dsl connection on eth1 and local interface eth0. Because of the NAT i cannot direct traffic to IMQ device in PREROUTING chain but have to use INPUT and FORWARD. So i use rules. iptables -t mangle -A INPUT -i eth1 -j IMQ --todev 0 iptables -t mangle -A FORWARD -i eth1 -j IMQ --todev 0 And now the strange thing: FORWARD traffic gets directed nicely to the IMQ, but

When I try to put all incoming traffic to IMQ on PREROUTING I can''t discern traffic to LAN and traffic to server. When I try to put only INPUT traffic to IMQ... I can''t discern traffic from LAN and from internet. Help me plizz to put all incoming traffic to one IMQ device and all outcoming to other IMQ device and (it''s very important) discern traffic to clients and

Hi! I have read all informations i could find, but some things are still not clear. My setup is: ---INTERNET1(eth0)-\ /- Local net1 (eth2) GW ---INTERNET2(eth1)-/ \- Local net2 (eth3) I have NAT and a working setup using HTB,SFQ, classifying with the iptables -j CLASSIFY way. I shape only the traffic coming from the internet heading to the intranet. I would like

Hi! I would like to thank very much for this great page with Kernel Packet Traveling Diagram and to suggest small update concerning IMQ. I think the sentence: "IMQ in input comes before nat so IMQ does not know the real ip address. Ingress comes after nat, so ingress knows the real ip address." could be more precise like that: "By default IMQ in PREROUTING comes before nat and

Hi I try setup imq pseudo device for shaping I''m work such script #!/bin/sh TC=/sbin/tc /sbin/modprobe imq numdevs=1 /sbin/ip link set imq0 up $TC qdisc add dev imq0 handle 1: root htb default 1 $TC class add dev imq0 parent 1: classid 1:1 htb rate 10mbit # client1 tunnel tunnel $TC class add dev imq0 parent 1: classid 1:2 htb rate 256kbit $TC filter add dev imq0 protocol ip parent 1:0

Hello, I have eth0 - internet eth1..4 - local networks on eth0 i do $IPTABLES -A POSTROUTING -t nat -o eth0 -j MASQUERADE I want to balance out/in load for eth1..4 and localhost (mainly squid). Nat makes impossible to do it on eth0, so I installed IMQ. I need to get to on imq0 unnnated in/out traffic that I could make priorities for protocols and networks. Do somthing like this: prate=1Mbit

Folks, I''m so surprised what happened to my box just in the few weeks lately. Here is my setup: INTERNET <----------> [eth0] SHAPER-BOX [eth1] <----------> USER-FARM both eth0 & eth1 got public ips (202.x.x.x) Why traffic monitored at eth0 is bigger than eth1 ? eth1 shaped just exactly the same as rate i defined in HTB. I just have 1024Kbps from my ISP and i defined the

I am attempting to implement IMQ on a 2.4.31 version kernel with iptables 1.3.3. I am following the example at http://www.linuximq.net/usage.html. When I enter the line iptables -t mangle -A POSTROUTING -o eth1 -j IMQ --todev1 (eth1 is the external interface), the computer slows to a crawl. OK, the CPU is only an AMD K6 233 which is not the world''s greatest CPU, but egress shaping is

Hi, All! I have kernel panic with using IMQ on my linux router. In archive of this mailing list i found reason of this truble: i used PREROUTING -j IMQ and POSTROUTING -j IMQ in one time but i don''t understand why this configuration is broken? I want to control all traffic on my external interface, for example i want to lease 30kbit/sec (inbound+outbound, without dividing) for encrypting

Hello, I am using the IMQ with iptables (latest versions) and asking all packets to be enqueued to IMQ0 from both prerouting and postrouting (using different iptables rules to mark different streams). When I do this I get the kernel saying: "Dead loop on netdevice imq0, fix it urgently!" and communications stop intermittently. If I remove the jump from either preroute or postroute it
