similar to: ip route tos not always work

hi all, I need different routes for packets with different TOS values, and tried to do this with ip. I noticed that ip does not recognice all possible values for the TOS byte, even when I enter them in /etc/iproute/rt_dsfield. to demonstrate this, I added prohibit rules for different marked packets and tried if the packets are dropped when I try to "ping -Q tosvalue <somehost>":

Hey, fellow LART controlllers, I''d like to ask if someome has a real esfq experience with HTB class hierarchy and esfq qdiscs. Lets say that I want to unite the connections to 10 client PCs with u32 or fw filters (doesn''t matter which one in fact) into one HTB class with esfq qdisc at the end. Did anyone tried it, and more important, did it worked the way it is supposed to? As

Which files do I need to edit in order to initialize a route after a reboot. I have a 802.1q tagged VLAN interface which I need to create a rule, and a route for. I see on my CentOs 4.2 box that in /etc/iproute2 there are the following files. I realize that I can add my tables to /etc/iproute2/rt_tables, but when I want to create a rule I am not sure where to put the information for the

During my tests I''m starting to feel stupid :). Traffic shaping works quite on its own. System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB version 3.6, interfaces eth0 and eth1 are acting as bridge br0. If TCP shaping almost works, it just exceeds limits UDP is not shaped. Traffic flows PC=>eth0=>eth1=>PC. Statistics shown is for just UDP traffic (1mbit of small udp

Hi all :) I''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq? Thanks in advance :) Ra?l N??ez de Arenas Coronado -- Linux Registered

Hello one more time, As others seem to already asked without reply, I''m getting lower speed rates than specified via ingress. How do I know. Because I have this in my script: tc qdisc add dev $DEV handle ffff: ingress # Filter intranet traffic, so fit it to intranet speed tc filter add dev $DEV parent ffff: protocol ip prio 10 u32 \ match ip src $Q_2_HOSTS \ match ip dst

Hi there! I am working a lot with VoIP in my company, so I thought to use linux bridge functionality together with tc to emulate delay, jitter, packet loss, duplication, reordering etc. for testing purposes in our lab against our VoIP products. I just recognized, that a basic bridge just with it''s minumum configuration of 2 network interfaces creates latency of approx. 5ms on very low

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''m absolutely new to tc and found The Ultimate Traffic Conditioner to be exactly what I wanted as a starting point. Now the script doesn''t behave as I expected though, which applies to both the CBQ and HTB versions, the latter of which being my preference. The only changes made to the script are these assignments:

Hello good day to all ... this is my setup 1 Linux Wireless Access Point, connected are 4 wireless gateway in which i needed to apply shaping ... ok here is the weird part... clients on each gateway download files from the Acess Point ... a 500 mb file through ftp on gateway 1 which is up to 64 kbps ... the result is from 60-64 kbps speed which is fine ... on gateway 2 which is 128 kbps ... the

Hi, all I''ve got problems with tc qdisc ingress. I''m using vanillia kernel 2.6.14.4 patched with http://www.ssi.bg/~ja/routes-2.6.14-12.diff, and iproute2-2.6.14-051107. i am using ingress to limit incoming traffic : (DEV is eth1 / DOWNLINK is 7700) # attach ingress policer: tc qdisc add dev $DEV handle ffff: ingress # filter *everything* to it (0.0.0.0/0), drop everything

Hello list members, Finaly I''m here after a week of trying to subscribe to this list... pfew... Anyway... I have a rather strange problem with tc. I am trying to police the ingress traffic into my network using the iptables MARK feature (in mangle table, PREROUTING) but it seems that tc filters ignore this marks and they don''t work at all for me. Let me explain a bit more in

Trying to figure out how to prefer voip traffic on a dsl line. Found a great howto: http://www.howtoforge.com/voip_qos_traffic_shaping_iproute2_asterisk but I'm trying to figure out the relationship between the tos of iax.conf and tos of tc from Iproute2. my traffic goes from my linux router to a CPE cisco box. I understand Cisco uses tos ( usually referred to as DSCP, just to keep us on

Hello all, I have a strange problem that I'd like advice on. Here I run several samba servers as home directory and print servers for an NT 4.0 (sp6a) domain. The domains relevant to this problem are CANNING and STUDENT. The STUDENT domain trusts users in the CANNING domain. My samba server is RedHat 6.2 (+ updates) running samba 2.2.7 (built today). I upgraded because of a different

Hi There, I am trying to match mac address and tos at the same time. It mostly works for all ports, but recently I discovered that it doesn''t, for example it does not work on port 554. For each client I have two classes, one is the "good" traffic that I mark using iptables with the line, for example: /sbin/iptables -t mangle -A PREROUTING -p tcp --sport 554 -j TOS

Hi, I''m trying to figure out how to use Linux QoS. Default setting has three queues (bands) and should prioretise outgoing tarffic based on TOS field. I try to test that by flooding Ethernet interface by netperf or iptraf and running ping -f with -Q and without Q. -Q doesn''t affect ping results, it suffers anyway. It seems that I don''t understand something. I verified

Hello, I want to set the TOS of packets that are entering in my network with value 0x00 (or other). For this, I''m using iptables with the next comand: iptables -t mangle -A FORWARD -i eth1 -s 0/0 -j TOS --set-tos 0x00 The problem ocurrs when my packets have a previous TOS of value difference from 0x00, because the comand do the next operation: OLD_TOS + 0x00 = OLD_TOS I would want

Hi all Tcpdump shows Kphone UDP traffic has not set as minimum delay traffic! This is a tcpdump from My-IP to Other-IP: 13:07:14.704501 IP (tos 0x0, ttl 64, id 813, offset 0, flags [DF], proto: UDP (17), length: 120) My-IP.32784 > Other-IP.10384: UDP, length 92 0x0000: 4500 0078 032d 4000 4011 0fce db4a 37e4 0x0010: d5ba 3e91 8010 2890 0064 50f7 8008 032e 0x0020:

Hi, how does gre tunnels handle the TOS/DS field in the encapsulated packet? Is the value copied to the encapsulating ip header? thx jason _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi I have a 1024/128 ADSL connection. I wanted to test the TOS field in IP Header. So I started aMule and let it use the whole upstream (16KB). Then I did: #iptables -A OUTPUT -t mangle -p tcp --dport 22 -j TOS --set-tos Minimize-Dellay (like here: http://lartc.org/howto/lartc.cookbook.interactive-prio.html) Then I ssh to one of my server on the Internet. The delay was awful. I could use
