Hi! Bored by previous lhype success, I tried to boot a debootstrapped debian over nfsroot, and lo, this almost works!

The boot process stops after: Starting periodic

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?

Hello, while investigating a report from Jan-Piet Mens (resulting in http://wiki.powerdns.com/trac/changeset/3109), we discovered that NSD (both 3.2.15 and 4.0.0b4) compresses labels in RP content. As far as I can see, this is not allowed by RFC3597 section 4 paragraph 1/2. PowerDNS Recursor, like Unbound and BIND, now deals with this as 3597 section 4 paragraph 4 says we SHOULD. Nevertheless,

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

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.

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

Hello everybody, I am trying to understand the Advance routing and Traffic control. In the examples section of the how to an example script is given. Section 15.8.2 (the ultimate setup for Your internet connection) The example says download is 800 and upload is 220 ###### uplink # install root CBQ tc qdisc add dev ppp0 root handle 1: cbq avpkt 1000 bandwidth 10mbit Maybe I am

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,

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.

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

Hi All, concerning the problem when running the "ip ru ls" command.
