Hi All , My first message and I have a little problem with my FC6 box trying to block emule traffic using layer7 . Here my network : Internet --------- ADSL Router ------------------- FC6 Box -------------------- Emule Box external ADSL : Dynamic Internal ADSL : 192.168.254.1 external FC6 : 192.168.254.3 internal FC6 : 192.168.253.1 Emule Box : 192.168.253.3 I guess that everything

Hi all I am using a pass trhu router and I need to QoS some clients output by its IP address. The problem is that QoS is due after NATing. Is there some clever way of doing this besides MARKing every packet with some IP hashing in POSTROUTING NAT table? Regards Ethy

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

I''m pretty smart, and was once regarded as pretty network and computer savvy. But the world has obviously passed me by! I have a server in a colocation facility, and I was recently hit by a bill for overage; I used more bandwidth than I expected, and I must pay. So now, I want to bother with packet shaping on the server. The *most* important thing is to clamp bandwidth to the 1Mbps

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 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

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

I have tried using iptraf for my NAT firewall to analyse the IP traffic. Basically I am faced with this difficulty of related the source IP to the outgoing interface to the internet, so I am wondering if anyone has a suggestion for a different ways to do it, or a suggestion for a better tool. Details :- Supposed : eth0 - LAN eth1 - WAN1 eth2 - WAN2 And then

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)

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

Hi, How can I delete an existing filter? Is it possible? I tried different combinations of tc commands but, while manage to delete an existing qdisc or class, I wasn''t able to find a way to delete an existing filter. The tc man page doesn''t even list the del command in the synopsis. tc filter [ add | change | replace ] \ dev DEV [ parent qdisc-id | root ] \

I am wondering whether the commands ''tc filter change'' and ''tc filter replace'' are working. Googling around revealed a few emails on the LARTC stating that unfoirtunately they do not work. A quick check showed that they are still not implemented (properly). Some propose a solution to build a second tree of filters and apply the 2nd one when a need for it

Hello I have few questions regarding tc functionality (qdiscs, classes, etc.) when vlans are in use. For example, consider interface eth0, for which I create and extra vlan with vconfig, let''s say eth0.11. Then using tc I can add usual things - qdiscs, filters, ... - to both eth0 and eth0.11. The questions are: - on which interface - virtual or real, should I actually use tc ? Or

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 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''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:

PATCH 1 ======= On my machine tc does not parse filter "sample" for the u32 filter. Eg: tc filter add dev eth2 parent 1:0 protocol ip prio 1 u32 ht 801: \ classid 1:3 \ sample ip protocol 1 0xff match ip protocol 1 0xff Illegal "sample" The reason is a missing memset. This patch fixes it. diff -Nur iproute-20051007.keep/tc/f_u32.c iproute-20051007/tc/f_u32.c

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.
