similar to: tcng TCP ACK match

I can''t seem to match packets less than 512 bytes: class( <$bulk> ) if tcp_dport == 81 && !( ip_len & 0xfe00 ) ; or if tcp_dport == 81 && ip_len < 512 Both rules match any packet I send to port 81, even when the total IP length is much greater than 512 bytes: class htb 2:4 parent 2:1 leaf 5: prio 1 rate 8000bps ceil 24000bps burst 6Kb cburst 1839b Sent

Hi all, I have a couple of questions regarding tcng behavior. First - I want to mark TCP_ACK packets as high priority, a common case. I figured the tcp_ACK rule in fields4.tc would be enough but I''ve come across Jason Boxman''s tutorial and he recommends using: class( <$ack> ) if ip_len < 64 && ip_hl == 0x5 && (raw[33].b >> 4)

My previous message (http://mailman.ds9a.nl/pipermail/lartc/2004q2/012285.html) didn''t generate any replies, so I thought I''d try posting what I''ve done trying to solve my own problem, in hopes that someone will take pity and show me if/where I''m going wrong. Just to recap, I''m trying to accomplish this on my server, which streams RealAudio files

Nobody knows something new about tcng? I really think that this kind of language help people, i order to do easier configurations i want to know how can i do in tcng a nested classes configuration with HTB? -- Juan Felipe Botero Ingeniería de sistemas Universidad de Antioquia _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Hello, its me again, I won''t stop sending emails to this list, until I solve this problem, I''ve tried several apps to create the right htb rules (even made them my self), but I always get the same results, traffic gets shaped, but I can''t use my bandwidth, and this is weird, because I should be able to, also I keep seeing download being limited too, and that

hi all, i''m having problems building a module from my tcng configuration file. could someone verify the syntax for building a kernel module? i did it as shown below ... module gets built but i cannot load it. thanks charles ps -- sorry, don''t know c++ :-) [root]# cat /etc/tcng.test #define LAN "eth0" #define LAN_INGRESS 750000 #define LAN_EGRESS 750000 dev

Greetings all, OK - just started playing around with traffic shaping - have imq and htb and (I think) everything else I need in the kernel and running well. My initial lab task was to protect a H.323 session over a simulated half T1 while adding bulk traffic - got that accomplished after slogging through learning tc and decided in short order that a more intuitive interface would be

Newbie here... tcng version 10b I''m just learning about htb and using tcng. I am trying to make the example in Martin A.

I had been using L7-Filter[1] successfully for edonkey/eMule traffic until recently. I upgraded to the latest release of mldonkey, 2.5.28a, which implements eMule compatibility, and with support for Kademlia[2] enabled, network latency increases greatly.

Hello, I setup iproute2 and iptables on my box, is a P4 2000 Ghz / 1GB memory. I have setup squid and iptables to be a transparent proxy, with cache. I''ve read on lartc.org almost everything and i want to ask if there is a u32 match for the connection time or something like that, or an u32 match for the packet number in a connection. All i want to do is shape the web traffic for long

I reported this previously and it was verified. Is this a bug in netlink or what? Who should I report this to? Original Oops report: http://mailman.ds9a.nl/pipermail/lartc/2004q2/012614.html Thanks.

Hi! I am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers?

hi all, long time since i posted on the list. just wondering if anybody has played around with hfsc and if so could he/she share their info on it thanks adrian -- To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

... is on SourceForge, http://tcng.sourceforge.net/#src This one has the first steps towards getting non-IPv4 classification right: - I''ve added fields for skb meta-data (meta_protocol, etc.) - if USE_META_PROTOCOL is #defined (tcc -D... or tcsim -Xc,-D...), ip_hdr and ip6_hdr check the protocol number - if_u32 generates distinct classifier branches for each protocol - f_fw,

Hi again, I just ran into a seriously strange glitch, and was wondering if anybody had experienced this... I have an HTB class with an iptables classifier. The iptables classifier shows packets hitting the rule for this class. Now, HTB drops these packets (''dropped'' increases), even although the packets are small, and there are over 10000 tokens available. Is there any

Hi, I have implemented QOS classifiers using TC with HTB. The classification is working. I would like to know whether there is some tool which will help me in monitoring the bandwidth share of the various classes. Thanks, Vinod C

I''ve used tc in the past for shaping, upon learning of tcng, I redid my config, and load it using tcc. I thought this was great, as the new script is much easier to maintain, and is so much simpler. The new script was working for about a week, then it stopped working. I now get this error: can''t dump subexpression (if_u32.c, unsupported offset sequence - please try to reorder

Hi All, I am new to tc so please forgive me. I have read as much documentation as I can get my hands on, but I still have problems with getting the rules right.
