similar to: tc filter priority

hi all people, I''m using tc and htb to create classes and do some QoS , but i would like to know if i can do it: after to create the classes I need to create the rules using tc filter : tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst 10.0.0.0/8 flowid 1:10 ok, this rule works with all packets going to 10.0.0.0/8, but how can i write a rule using "!"

Hello lartc, Testing some rules I found out that any rules are slowing down large pings! For example: tc qdisc add dev eth0 root handle 1: htb tc class add dev eth0 parent 1: classid 1:1 htb rate 100Mbit prio 1 ceil 100Mbit tc class add dev eth0 parent 1:1 classid 1:2 htb rate 100Mbit prio 2 ceil 100Mbit tc filter add dev eth0 parent 1:0 prio 5 u32 \ match ip src 10.10.10.1 \ match ip

How can i redirect all traffic that not come from port 80 to a flow ? i was thing about some like tc filter add dev imq1 parent 1: protocol ip prio 7 u32 match ip sport !80 ...... But this not work. Another doubt, if i have two rules that intersects , for example , one filter with u32 match ip src 10.10.10.10 flowid 1:10 and other with u32 match sport 80 0xffff flowid 1:11 , which one will

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, I have recently started to use ''tc'' on ipv6 traffic and have come across an issue with tc filter. As per tc_filter.c in iproute2-050816, to match ''priority'' of an ipv6 packet, the u32 filter matches against the first 8 bits of the packet. From f_u32.c: if (strcmp(*argv, "priority") == 0) { NEXT_ARG();

Hi All, I''m configuring my natting-firewall to do some tc shaping. Some traffic has to be shaped on 30mbit, some on 10mbit all the others are unlimited. The configuring and filtering works correctly. The traffic that is shaped at 30mbit is correct, but the traffic that is shapped at 10mbit only gets to 100KB/sec. It is on a device configured with bonding (both in and out interface).

Woops - my fat fingers hit the send key before I could put in a subject a minute ago. Hello - I am using kernel 2.4.27 and running into behavior I don''t know how to explain. I have 2 relevant interfaces. eth0 is external, eth1 is internal. My internal LAN is 10.10.10.0/24. My External range is 1.2.3.0/27 (dummied up). I have an H.323 videoconference device inside my internal

Hi, I can''t get traffic shaping working. This is my situation: -------- ------ Net1 ----- |router| -------------------- | TC | ----------- Net2 -------- leased line ------ eth1 eth0 We use the leased line for normal traffic but also for synchronisation between 2 servers. The leased line is 2mbit. The synchronisation

Hi, Is there any tested good HTB script for traffic shaping available like as that of CBQ available at. http://freshmeat.net/projects/cbq.init I am n new bie and need to work on htb. -- Regards, M Arman _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi everybody, i am new to this list so dont blame me if i will talk about nothing.. At this moment i am experimenting with htb + tc u32 filters , the problem is that i want some traffic to be unshaped so i did this.. tc qdisc add dev eth0 root handle 10: htb default 20 tc class add dev eth0 parent 10: classid 10:2 htb rate 256Kbit THIS IS TRAFFIC I WANT NOT TO BE SHAPED tc filter add dev eth0

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

Hello everybody on the list, I have the following situation where I want to police the speed of incoming packets from specific subnets to 1024kbps and then police all the rest to 256kbps, which is the speed my ISP grants for the rest of the internet. So, eth1 is the one connected to the cable modem and then to the internet. I do: tc qdisc add dev eth1 ingress handle ffff: then: tc filter

hi! Sorry in advance if I am not on the right mailing-list and sorry if my question is cover somewhere is doc (I didn't find anything). The result from nmblookup (same result on all platform) for a given samba server isn't what I expect. The key part of my smb.conf is: [global] netbios name = ourserver2 netbios aliases = ourserverdev ourserverlab ourserver name

Dear all, I''m having real problems getting tc to do anything useful at all. I''m also under pressure to get this fixed before the students start arriving later this month (I work in a university). In short, I want each IP address to be hard limited to 128kbit down, 64kbit up, never to be allowed more bandwidth than this. It is also important that the latency remains

Hello, After setting up Samba 3.5.6 on CentOS 5.5 (built from sources) I have noticed a strange problem. Windows 2003 servers participating in this Samba domain do not receive domain groups list when I, say, try to assign security credentials for a file/folder. When I choose domain as source, search reveals only technical group names and individual domain users names. No domain group names

Hello, I am trying to run Xen 3 on FC5, but I cannot have the eth0 interface appear in domU. I have 3 servers running FC3 and Xen 2 with various domUs since a year. Everything is fine on that front. I took one of the server, upgraded it to FC5 and did the following: - yum install xen kernel-xen0 kernel-xenU - grub.conf contains title Fedora Core (2.6.15-1.2054_FC5xen0 root (hd0,0) kernel

Hi everyone, I''m new to tc but I need to use it to set up shaping on a new NAT box. In short: Each user must have their upload limited to 128kbit and downlink limited to 256kbit. Global bandwidth to be limited to 100Mbit Interactive packets to have higher priority 200+ users, so need to match packets fast So far I have managed to get the download limits working. However I need to

Hi list, I''m playing with tc and found a strange behavior when I try to delete filters. For example, this simple scenario: tc qdisc add dev eth1 root handle 1: htb default 100 tc class add dev eth1 parent 1: classid 1:1 htb rate 128Kbit tc class add dev eth1 parent 1: classid 1:2 htb rate 258Kbit tc class add dev eth1 parent 1: classid 1:100 htb rate 32Kbit tc filter add dev eth1 parent

I''m trying to configure 4 queues with strict priorities based on DSCP. I tried to following commands, but it seems that the filters I defined have no effect tc qdisc add dev eth0 root handle 1: prio bands 4 tc qdisc add dev eth0 parent 1:0 handle 10: pfifo limit 100 tc qdisc add dev eth0 parent 1:1 handle 20: pfifo limit 100 tc qdisc add dev eth0 parent 1:2 handle 30: pfifo limit 100 tc

Hello, it seems, that filtering on nexthdr (TCP/UDP) content, especially src or dst port, is not working. The following has no effect on 2.4.16 or older (even 2.2) kernels: # tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match tcp dst 3128 0xffff police rate 40kbit burst 10k drop flowid :1 Even if # tc filter ls dev eth0 parent ffff: filter protocol ip pref 50 u32 filter protocol
