tc: u32 match in nexthdr not working?
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

How does tc communicate with the kernel?
Hi, I am developing on an embedded MIPS-based system; I have iproute2''s ip working correctly talking to the kernel, but tc seems to be broken. I''d like to fix this, but I need a little bit of help in figuring out how tc communictes with the kernel -- can someone tell me the places I should be looking? Thanks. Joseph

delete tc entries
I''m a newbie to tc and after some experimenting I have the following problem: # tc qdisc show qdisc sfq 8006: dev ipsec0 quantum 1514b perturb 15sec I can''t get rid of this entry. Is there a way to clear all entries? I tried all sorts of "tc qdisc del xxx" but nothing seems to work. It says: RTNETLINK answers: No such file or directory What syntax do I need to

Stealth Router
Hi, in FreeBSD kernel is options that make router stealth, packet passed throw router have no change in TTL value. Is a posibility to make similar thing in Linux, I think that in traceroute isn''t this hop, no asteris, no router, no change in TTL, nothing ...? PSIkappa psi@atlantis.sk

TBF settings
I presently use TBF with this syntax: tc qdisc add dev eth0 parent 1:100 tbf buffer=15000/8 LIMIT=30000 MTU=1500 parent class is a cbq with rate=128Kbit when I want to add PEAK, I get always RTNETLINK error: Invalid argument. Maybe be I don''t understand this parameter. What I know about it, it''s that it can control short-term burst traffic, and it''s what I need to do.

How can I create qdisc, class, and filter inside the kernel?
Hi, I am writing a kernel module which works with netfilter. If a certain condition matches, I want to create a qdisc, a class and a filter inside the kernel module. How can I create qdisc, class, and filter inside the kernel?

Multiple bands with equal priority ?
I''m trying to build a wan latency test environment, where packets from different "remote" locations get delayed by different amounts of time, depending on which remote location we''re pretending they are from. Currently, I''m doing this using the ''prio'' qdisc to obtain multiple bands, and hanging a different netem qdisc off each of the branches

TEQL: 2 Mbit eth1 + 2Mbit eth2 = 1Mbit teql0
Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup the routers to use TEQL with one of the

How to MARK NATtted packets coming from external interface to an internal host ?
Hi, I would like to control download bandwidth from the Internet for clients inside a network. The gateway is a Linux box using ''iptables nat''. I would like to use ''iptables mangle'' to mark the packets coming from the Internet and going to specific clients and then use CBQ to shape it: +-----------+ Internal network | Linux

Marking returned MASQ'ed packets (ingress, TC, etc.)
Hi Folks, I''m using a 2.4.x kernel and TC from the iproute2 package so that I can limit traffic through my gateway. I''m using this to mark packets when they leave the LAN: /sbin/ipchains -A forward -j MASQ -i eth0 -s 192.168.1.0/24 -d 0.0.0.0/0 -m 1 When the packets return, I need to have them marked again so that the ingress filter will limit the bandwidth in the opposite

Anti-CBQ Statements in Howto
I find the negative attitude toward CBQ to be distracting and non-professional in the HOWTO. I''ve re-read it for the first time in about a month and comments like "This can be configured in a variety of ways, which I do not understand. Use HTB" do not encourage me about the writer. This is not a personal critique, as I can imagine this being said on a personal website,

Suggestion to the Advanced Routing HOWTO
I''d like to make a suggestion to the Advanced Routing HOWTO. I have read parts of it some months ago and I had a hard time following it and I think that I know the reason: the HOWTO doesn''t give the background on the subjects it discusses. This difficulty was particularly evident when I was reading the part about Quality of Service/Bandwidth Shaping. I got the impression

transport multicast traffic through a gre tunnel.
Hi All, As it is written in the "Linux 2.4 Advanced Routing HOWTO" GRE tunneling has some benefits compare to IP-in-IP, on of it benefits is the ability to transport multicast traffic through a GRE tunnel. I used the mrouted daemon and I know that the daemon supports tunneling but I don''t want to use its tunneling method. Assuming I have gre0 as my tunneling device I did the

Ideas...
Hello, My company runs several Internet Cafes in Mexico, where bandwith is limited and very costly. We use Linux to do NAT and firewall stuff and at each location we have about 30-40 stations. I''d like to know if anyone out there has any suggestions about how to use CBQ to limit the bandwith at each station. We only have a 128k circuit. The problem I am having is that since I have that
