similar to: PRIO and TBF is much better than HTB??

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

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 cburst 1839b Sent

Dear List, I am wanting to perform some traffic shaping as the subject of this email suggests. What I am wanting to do is this; I would like to have traffic shaping performed on the following protocols: HTTP, RDP, GRE, PPTP, SIP and IAX. Obviously I would like to have highest priority set for voice packets so much so that the general http traffic does not impede on the voice packets. I

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 ) {

Hey people, I have the following tcng configuration: #include "fields.tc" #include "ports.tc" dev "eth0" { egress { // Voice traffic class (<$voice>) if udp_dport >= 20000 && udp_dport <= 23000; // SSH connections class (<$interactive>) if tcp_dport == PORT_SSH; //

Hi all, I have read the larc howto and I need to apply a traffic shaper with this configuration: router / two interface etho and eth1 lan 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 irc) connection at 15

Hey all, i have a class. class ( <$call1> ) if ip_dst == 10.100.1.6 && tcp_dport == 22 if ip_src == 10.100.1.4 && tcp_sport == 22 ; Now when i apply this traffic TO 6 on port 22 is indeed limited to the speed i specify BUT it doesn''t seem to take the src into account at all. If i change the src to anything, even an address that

Hello, I''ve been trying to shape the bittorrent traffic (on my external interface, upload), but without luck, for this I''m using layer7 filter right now, but I''ve also tried ipp2p, with the same results, I might say that this is not a problem with this packet classifiers, the problem is with HTB, here''s why. When I open azureus (the bittorrent client I

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 eth1 and

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, Diego --

Hi, I wanted to configure the following : 1. VPN + some other special connections (TCP 82,8282,23,22 and ICMP) to have priority over the rest 2. special upstream for our updating system on port 4000 3. within the VPN tunnels citrix traffic ( TCP 1494, 2598) + icmp has priority I need this for both incoming and outgoing traffic as it is the bandwith managment config on a central system from

I''m trying to setup a bottlekneck scenario so I can see the effects of the RED qdisc on a congested interface. My example simulation code is at the bottom of this email if someone wants to see it. The following is a snippet form TCSIMs output. 0.602000 E : 0x80bc080 40 : inputB_eth0: 45000028 00000000 40060000 ... 0.602000 D : 0x80bc080 40 : inputB_eth0: 45000028 00000000 40060000 ...

Hi All Could a VPN be used to help with SIP Tunneling and QoS issues. State 1: Two IP Networks Connected via the Public Internet transmitting VoIP Traffic Say a VoIP User and VoIP Termination Provider. Each side can put QoS onto their part, but if QoS does NOT exist between them then call quality will be bad anyhow. State 2: Same as above except a VPN tunnel is setup between each side. Thus

I''ve been having a bit of difficulty with a hierarchy of HTBs that I''m wanting to create. Essentially, I''ve got one interface that goes to both the DMZ and the internet. When going to the internet, some of the traffic will be going through a VPN and therefore I want to prioritize it differently, however I want to give the DMZ traffic full speed as long as it

Hello Mailing list, I have a problem with the prio qdisc and I don´t know what is wrong in my configuration This ist a sample configuration and looks like this: #include "fields.tc" #include "ports.tc" #define X16(i) i i i i i i i i i i i i i i i i dev ppp0 { dsmark { prio(bands 6, priomap X16($be)) { class if ip_proto == IPPROTO_UDP;

Hey, I currently have a box serving as a firewall (running iptables) and packet shaper (using tc / tcng''s tcc compiler) to shape a large amount of inbound and outbound traffic to my data center. Whilst I can perform shaping functions using HTB, I need to also provide an absolute (to the nearest few 100kb/s) bandwidth usage maximum. As an example I might have 200MBit/sec

Newbie here... tcng version 10b I''m just learning about htb and using tcng. I am trying to make the example in Martin A. Brown''s Traffic Control with tcng and HTB HOWTO v0.5 example 2 /* * Simply commented example of a tcng traffic control file. * * Martin A. Brown <mabrown@securepipe.com> * * Example: Using class selection path. * * (If you are reading the

Ok, earlier I post a message explaining my problem with HTB and layer7 (or ipp2p), about not being able to shape the traffic. Well, actually this is what''s happening, I''m marking the packets (right now, I''m using ipp2p as Klaus adviced me to) with iptables, and my queue rules are made using tcng, I''m using the HTB qdisc, and traffic is going to the HTB class

Thank you for your help. It generates this script : tc qdisc add dev eth0 handle 1:0 root htb default 2 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 75000bps ceil \ 75000bps tc class add dev eth0 parent 1:0 classid 1:2 htb rate 125000bps tc filter add dev eth0 parent 1:0 protocol all prio 1 u32 match u32 \ 0xa000001 0xffffffff at 12 classid 1:1 But I thought it was necessary to
