similar to: Detect and mark ''bulk'' http traffic

After varying degrees of success with p2p detection modules, I would like to write the following rules using iptables to reliably identify p2p traffic: 1. If a host on the network has 5 or more simutaneous tcp connections to ports above 1024, mark all connections to ports 1024 and above as 60. 2. If a host has received (or sent) UDP packets from 5 different hosts'' ports above 1024 in a

Hello list. I''ve configured a very simple script to slow down packets coming from a particular IP Address. I''ve used IPTABLES to mark traffic coming from this IP Address, but it does not appear to be working as expected. Let me first describe my system as maybe what I''m doing is beyond what NETFILTER can do. I have one machine that runs all my servers as

Hi all, I have been trying to investigate traffic shaping in an effort to solve the "unfriendly network apps" problem on a test network. I have a basis by which I''d like to shape traffic, but studying the howto doesn''t uncover and existing qdisc that seems to fit what I would like to do. The problem I would like to address is to prevent an IP address opening 10

Hi, I''ve been wondering if anyone has thought of a way to differentiate between an established http download and interactive http traffic? I would like to give interactive http traffic priority over someone downloading large files. Has anyone any ideas how to detect packets that are part of a download like this? Thanks. _______________________________________________

Hi I believe that whole question is in topic. Is there any way to recognize ( and then shape ) p2p traffic which is encrypted? Modern p2p clients have this ability moreover some of them have this enabled by default. Now I''m using ipp2p for iptables but as I know this doesn''t recognize encrypted traffic. Thanks in advance.

Hi, I''m a complete newbie at this traffic shaping / QoS stuff so please excuse me if this is a silly question. I''ve searched and searched on Google and I just end up confusing myself even more, so I thought I''d post my question to this list and see whether someone can help me! Basically, I am running a Linux box as a NAT router on my home network (machine name marvin).

Hi, I''m trying to divide my bandwidth between different services, but I''d like to take into account the number of active users. For example, l want divide my bandwidth between HTTP and SMTP and guarantee HTTP 80% of the bandwidth. However, I have many users on my system (tens of thousands) and if only 1% of my active users are using HTTP (and the other 99% SMTP), I''d

Sir, I have one 2 MB link which I have to distribute to 200 people. Caching may enchance performance. Kindly suggest packages for this purpose under GPL.

I am trying to vectorize the function void bar(float *c, float *a, float *b) { const int width = 256; for (int i = 0 ; i < 256 ; ++i ) { c[ i ] = a[ i ] + b[ i ]; c[ width + i ] = a[ width + i ] + b[ width + i ]; } } using the following commands clang -emit-llvm -S loop.c opt loop.ll -O3 -debug-only=loop-vectorize -S -o - LV: Checking a loop in

I have a router with about 300 clients connecting to it. It has htb with a class per client. I wnat to create a script to prioritise www trafic and ssh trafic over p2p trafic.... this is a sample of what i have now: /sbin/tc class add dev eth0 parent 1:5 classid 1:8012 htb rate 35Kbit ceil 281Kbit prio 6 /sbin/tc qdisc add dev eth0 parent 1:8012 handle 8012 sfq perturb 8 /sbin/tc filter add

Hi all, Since the mail list receives a lot of repeated subjects (for example: "i have two adsl lines..."), maybe these specific issues should be treated on the LARTC Guide, or maybe if we had an wiki? Is there a LARTC Wiki? If not, what do you think about creating one? Thanks -- Marco _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Dear All, I want to limit traffic that use by my client to download files directly from browser, I have already limit the traffic for the same purpose to ftp connection. But I don''t want to limit traffic that using for browsing the web. Can I do this with IMQ/HTB or any other method to make this happen. Thank You. Sorry my English is bad. RInto Exandi

Hi, I have a PC that acts as a VoIP gateway using an internet telephony provider to make phone calls.. Data between me and the provider will always be from one IP address on my internal network to the provider.. I have a 1Mbps/256Kbps ADSL line and the voice stream is highly compressed requireing only 30Kbps of bandwidth.. The problem is that when my Mozilla Mail client polls for mail or

Bingo! That works (when coming from C source) Now, I have a serious problem. I am not coming from C but I build the function with the builder. I am also forced to change the signature and load the pointers a,b,c afterwards: define void @bar([8 x i8]* nocapture readonly %arg_ptr) #0 { entrypoint: %0 = bitcast [8 x i8]* %arg_ptr to i32* %1 = load i32* %0, align 4 %2 = getelementptr [8 x

Hi Nadav, Arnold, I managed to find some time to work on the pointer reduction, and I got a patch that can make "canVectorize()" pass. Basically what I do is to teach AddReductionVar() about pointers, saying they don't really have an exit instructions, and that (maybe) the final store is a good candidate (is it?). This makes it recognize the writes and reads, but then

Thanks for the alternatives! I am trying the 'extracting sub-function' approach. However, it seems I can't get the 'subfunction' to pass the verifier. This is my subfunction: define void @main_extern([8 x i8]* %arg_ptr) { entrypoint: %0 = getelementptr [8 x i8]* %arg_ptr, i32 0 %1 = bitcast [8 x i8]* %0 to i64* %2 = load i64* %1 %3 = getelementptr [8 x i8]*
