similar to: IMQ htb question

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

hi stef oone more pb while shaping incoming traffic with imq .this one tc qdisc add dev imq0 root handle 1: htb default 20 tc class add dev imq0 parent 1: classid 1:1 htb rate 2mbit burst 15k tc class add dev imq0 parent 1:1 classid 1:10 htb rate 1mbit tc class add dev imq0 parent 1:1 classid 1:20 htb rate 1mbit tc qdisc add dev imq0 parent 1:10 handle 10: pfifo tc qdisc add dev imq0 parent

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

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

Hi all and tc Gururs i have patched the IMQ and htb to kernel, but when i do egress filtering, iam not able to see any traffic and excusted the following the commands modprobe imq numdevs=1 tc qdisc add dev imq0 handle 1: root htb default 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 100kbit tc qdisc add dev imq0 parent 1:1 handle 10: htb default 1 tc class add dev imq0 parent

On my debian woody (kernel 2.4.31) the tcpdump doesn''t work with imq0 devices. If I try to tcpdump imq devices there is no packet seen: [...] rt1:~# tcpdump -n -i imq0 Warning: arptype 65535 not supported by libpcap - falling back to cooked socket tcpdump: WARNING: imq0: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on

Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration

Hello, I have a serious problem with HTB which I wasn''t able to solve myself. I run a masquerading router with ppp0 as interface to the Internet. Three clients need to share a downstream of 1 MBit, which I want to divide with tc. When I see a packet being forwarded to one of these clients, I give it the appropriate unique mark: iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

i''m trying to limit upload and download but something is wrong(it is about NAT) i will post here my "script" maybe someone could tell me what is wrong my kernel(2.6.9) is patch with imq(linuximq.net) and my iptables(1.2.11) also #flush tc qdisc del dev eth0 root tc qdisc del dev eth1 root tc qdisc del dev imq0 root tc qdisc del dev imq1 root ifconfig imq0 down

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

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

Hello, I''m trying to get my shaper to work, but have only a partial success. Can someone help me with that. My setup unfortunately is not so trivial, but I think some people could have similar one... 1. There is a router connected to the internet line via interface eth0 2. There are users connected to the router via two interfaces : eth1 and wlan0 3. All users are assigned private IP

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

Hello, I wrote a simple traffic shaping script (below) that should have allowed me to shape my internet traffic a bit (ppp0 - adsl 128kbit/64kbit; local interface eth0). The script works only partially - the speed is being limited but too much. Without running this script my download rate is about 10kBytes (with second computer also downloading at about 6kBytes). After running it my download speed

ive got such network: |--------| |-------------| | WORLD |---|ROUTER/server| ------ NATED LAN |--------| |-------------| I want to use imq on ROUTER, what behaviour to choose ? AA, BA, AB, BB ?? --

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 folks, I`ve a problem to use HTB and SFQ. The first script, below, to show a simple configuration, does work fine...!!! But, in the second example, does not work, becouse i put more code to clasify the traffic by protocol, http and ftp in this case. Somebody can tell me the errors? Thx, in advance.- NOTICE: IMQ device is to asociate with ETH1 my external iface. SCRIPT que funciona:

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
