similar to: Problems matching by mac address

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

Hi Is there a way of marking packets by mac address instead of ip or ports using a "tc filter u32 match"? I read somewhere that I could use the offset -8 and -14 to grab the mac addresses but if I use anything lower than -8, for example -9, I get an error. I''m modifying the wondershaper script to cap the download speed by mac address. Any sugestions?

Hi All, I''ve been playing with QOS for a short while now and have worked out how to do what I want using HTB. Great queuing discipline btw. My problem is the tc filters I want to setup aren''t working because iptables is getting to the packets first and mangling the src address. The iptables script I am using is MonMotha''s Firewall 2.3.8 and it includes lots of nice

ingress can be used to control the incoming packet, such as: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.11 police rate 10kbit burst 10k drop flowid :1 tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.22 police rate 10kbit burst 10k drop flowid :2 first ,I do not sure these method can

Hi all. I would need to use a single physical interface on a Linux box to manage two different IP addresses (belonging to two separate logical subnets) with two different MAC address. (I need to emulate te presence of two separate physical interfaceses for a PC on the same LAN, at layer 2 and layer 3). Is it possible to use the linux ethernet bridging code and two tap interfaces for this

Hi, machine: AMD K6 200 MHz Linux distribution: Mandrake 8.1 kernel: compiled 2.4.21 applied this: #define PSCHED_CLOCK_SOURCE PSCHED_CPU in file linux/include/net/pkt_sched.h bevore compiled the kernel (described on http://www.docum.org/stef.coene/qos/faq/cache/40.html) bandwitch on eth0: 128kbit The most simple configuration - 122kbit guaranted for WWW (sport 80) and

Hi All Can someone tell me what am I doing wrong? These was suposed to catch icmp type 8. Why ''match u8'' does not work? # tc filter add dev eth0 protocol ip parent 1: prio 2 \ u32 \ match u16 0x0800 0xffff at -2 \ match u8 8 0xff at 20 \ flowid 1:5 Illegal "match" # # tc filter add dev eth0 protocol ip parent 1: prio 2 \ u32 \ match

I have some problem with traffic shaping on debian testing. I actually posted a full config on the list a while ago but didn''t get any answers. The problem is that traffic doesn''t get into the user classes (~150) when I associate a class with a qdisc. I tried sfq, fifo but none works. If I dont''t associate a qdisc with a class classification occurs well.

I''m trying to implement something similar the the diagram in section 9.5.2.1 in the LARTC HOWTO, but must have missed something somewhere :( I''m trying to hack up wondershaper, as it looked like a good place to start.. Here''s where I currently at, but I''ve tried alot of different things, all failing, some worse than others. The end result is to throttle back 126

Hi, I am attempting to set up some simple outbound shaping following the LARTC HOWTO. The HTB qdisc seems to work as the documentation says, but my filters don''t seem to be working. All of the packets go to the default queue regardless of what filters I set, it seems. (according to tc -s qdisc show) I am trying to get this working on my openwrt box (whiterussian rc6), but when

I thought that the below email would be of interest to LARTC readers. I wasted quite a bit of time tracking down this "feature" (bug?). Any comments that shed light on this would be appreciated. In short, "tc filter" + htb + bridging works only with ip_forward off. Andrew Athan ----------------------------------------------------------------------- All: It seems that

I am trying to shape a client (somewhat advanced). This is my target: Client is 192.168.2.224. I would like to allow him to download with 500000 bits/sec in general. But, for a specific port(say 22), i would like him to download with 300000 bit/sec only. The problem is that my configuration (maybe wrong) allows him to download with 800000 bit/sec. (500000 generally + 300000 on port 22) I thought

Hi, I''ve failed miserably in my endeavours so far and I''m at the point where help would be much appreciated. I want to have 3 bandwidth limited classes on my Internet interface. In each of those classes I want 3 prioritization bands, and then use "tc filters" to place the traffic into the correct class and priority. The problem is that the traffic

please, help, i have build vpn server (suse 9 + poptop), i have managed to implement tc htb in ip-up script, but every client has own ppp interface (ppp0, ppp1, ppp2...), and my idea is to share available bandwidth, not to limit connection, how to build root tc rule, when I have more then one interface?... please any one width experiance regards _______________________________________________

Hello everyone! I''m simply trying to put a PRIO inside an HTB (used to throttle). I''ve got interactive traffic on the network that I want to give priority (VoIP + Citrix + Video). I''ve used the filters in a CBQ script fine, but am having trouble adjusting them to this setup such that they properly assign the traffic. tc qdisc del root dev $e tc qdisc add dev $e

Hi all, I''m experimenting with HTB and the prio parameter and it does not give me results I expect. I''ve created 4 HTB classes: 1:10 TCP ACKs (prio 0) 1:20 TCP traffic on dst port 10001 (prio 1) 1:30 TCP traffic on dst port 10000 (prio 2) 1:40 Default (prio 3) ceil and rate parameters are the same for all 4 classes (rate is

I have linux box (does nat and firewall for small network) connected to dsl. I want to set priorities for protocols (that nothing could disturb web browsing). This is my rules (eth0 connected to internet): /sbin/tc qdisc del dev eth0 root /sbin/tc qdisc add dev eth0 root handle 1 htb default 30 r2q 100 /sbin/tc class add dev eth0 parent 1: classid 1:2 htb rate 900Kbit burst 15k /sbin/tc class

During my tests I''m starting to feel stupid :). Traffic shaping works quite on its own. System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB version 3.6, interfaces eth0 and eth1 are acting as bridge br0. If TCP shaping almost works, it just exceeds limits UDP is not shaped. Traffic flows PC=>eth0=>eth1=>PC. Statistics shown is for just UDP traffic (1mbit of small udp

Server : eth0 - internet DSL eth1 - LAN wlan0 - wireles LAN I want server to share bandwith from eth0 evenly for users on eth1 and wlan0. How can i make it ? Is it possible ? As far as i know htb splits outgoing bandwith on one device only. ---------------------------------------------------- Grypa? Damy radę!
