similar to: tc filter not filtering -or- what am I going wrong?

I''ve done some tests with TC FILTER and his PRIO and think that is an error or OMISION on TC FILTER DOCUMENTATION from: http://lartc.org/howto/lartc.qdisc.filters.html#AEN1100 Let''s say we have a PRIO qdisc called ''10:'' which contains three classes, and we want to assign all traffic from and to port 22 to the highest priority band, the filters would be:

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 Guys, I have a couple of problems that are driving me nuts. This is the script I am using to setup restirctions and bw limitations: #Adding root class. tc qdisc add dev eth0 root handle 1: htb default 10 &>/dev/null tc class add dev eth0 parent 1: classid 1:1 htb rate 100Mbit ceil 100Mbit burst 2k quantum 1536 tc qdisc add dev eth1 root handle 1: htb default 10 &>/dev/null tc

Hi all. I''m going on my 3rd week trying to get a simple traffic shapping to work the right way :( !! My goal it to shape the traffic coming from one machine (pc1) to another machine (pc2) throught the "eth0" interface. My test configuration is as follows: PC1   IP: 192.168.105.237   Mask: 255.255.255.0   OS: Red Hat Linux Kernel 2.4.20-8   Rules:

I shape my upstream cable link with HTB from a script. My voip traffic (from the 192.168.0.14 host) gets priority over everything else to the near-starvation of other classes; the rest of the traffic is split up based on some priority rules (qos, empty ack packets, etc). eth1 is the uplink I''ve been using HTB and fw marking for the job until recently, when I changed the queue structure

Hello, I have wrote some scripts to shape about 1000 workstations. My config: Pentium IV - 2GHz, 1Gb RAM, RedHat Enterprise Advanced Server 3, kernel 2.4.21-9.EL, iproute-2.4.7-11.30E.1 2 Gigabit Lan cards in bridge mode. I use htb. Everything work fine, but I have troubles with showing running configuration. # Init shaper root for dev eth0 tc qdisc add dev eth0 root handle 2: htb default 200

I need to shape traffic from some IP on one LAN, but I''m in trouble. There is a linux 2.4.26 connected to the Internet (eth0) / LAN(eth1) doing NAT. I''m using VLANs in the LAN Interface, that is connected to a 3Com SuperStack II in a 802.1Q tagged port. I want to create a class that will limit the traffic at 384Kbit/s. I want to create two leaf classes that limit the traffic at

The interface is setup like this: # tc qdisc del dev eth0 root # tc qdisc add dev eth0 root handle 1: htb default 2 # tc class add dev eth0 parent 1: classid 1:2 htb rate 20mbit ceil 20mbit If I add a second class and a filter to send traffic to it like this: # tc class add dev eth0 parent 1: classid 1:130 htb rate 1Mbit ceil 1Mbit # tc filter add dev eth0 protocol ip parent 1:0 prio 130 u32

Hi, I am currently working on the TC. I have seen some behaviour which seems to be odd. I know someone in the mailing list would have seen this problem or may have some fix for this problem. When I try to include u32 filters with different priority or pref, I could see the filters being set on all the priority''s irrespective of the priority number. See my sample script below and the

Hi all! :) I see that this is partially covered in the mailing list archive but at the moment I can''t find a straight & working answer. I have an imq device with dynamically attacched classes/qdiscs/filters. There is a hashing filter that maps the last octet of an user''s IP address to a class (and associated qdisc). The "empty" filter looks like this: filter

Hi! By iptables I set marking (-j MARK) just before -j IMQ. There are only three marks. Exectly all of them are ditected to 1:20 Why I see 3 pkts in default 1:30? How explain it? ### imq0: queueing disciplines qdisc htb 1: r2q 10 default 30 direct_packets_stat 0 Sent 631429 bytes 1812 pkts (dropped 0, overlimits 20) ### imq0: traffic classes class htb 1:20 root prio 0 rate 100Kbit ceil

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hey Andreas, how i catch this traffic using L7 filter?, i´ve installed l7 filter now, but i don´t kwnow to use the kind of filter...!!! Can you help me?

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 How can I control which filter a packet will meet first? I have tried changing the order of applying the tc filter scripts and switching flowid number, but ''protocol ip u32 match ip src <ip net> match ip src 0.0.0.0/0'' always kicks in first? >From my script -------------------- # All traffic - Priority: Low tc filter add dev eth0 parent 1:0 prio 2 protocol ip u32

Dear all, I have big question in my mind about "tc filter" sintax. If I give "tc -s -d filter sh dev eth0" command, then the output is like below : filter parent 1: protocol ip pref 1 u32 filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:2 (rule hit 21553629 success 37907)

Dear Admins and Hackers, maybe i am to stupid to use ''tc''. But i having logical Problems to understand the Filter Rules in tc. Common Config: There is a Linux Engine (Debian) with a 2.6.11.11 Kernel which act as Packetshaper. Two Interfaces eth0 and eth1 are installed. Interface ''eth0'' is the Firewall Side Net 195.185.185.0/24. Interface

Hi All I am fighting this for 3 days and could not find any reason it is not working the way I want to (or I the way think it should). Internet output interface = eth2 (htb qdisc) Internet input interface = imq0 (eth2 attached - htb qdisc) main class = imq0 1:1 sub1 = 1:ffff (default) sub2 = 1:10 (src ports 1433/tcp or 1434/tcp or 81/tcp or 82/tcp) sub3 = 1:11 (src and dst port 25/tcp )

Alejandro, So, i did try the script that you give to me, and the problems its continues.- Maybe the problem was in the IPTABLES rules, i attach the complete script below: ##################### ifconfig imq0 up tc qdisc add dev imq0 handle 1: root htb default 30 tc class add dev imq0 parent 1: classid 1:1 htb rate 500kbit ceil 2000kbit tc class add dev imq0 parent 1:1 classid 1:10 htb rate

Hi, I am very new to tc. I added a filter using the following command: tc filter add dev eth0 V parent 20:0 protocol ip prio 1 handle ::128 u32 match ip tos 0x44 0xfc flowid 20:1 To check if the filter rule was indeed added, I run tc filter show dev eth0 parent 20: This gave me the following output: filter protocol ip
