similar to: How to fight with encrypted p2p

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 I''ve setuped a bridge with l7-filter and ipp2p. We have every day + or - between 10Mbits and 30 Mbits P2P traffic from + or - 450 customers. When traffic increase. I''ve got this kind of error message : Feb 23 14:26:19 gestor1 kernel: printk: 38 messages suppressed. Feb 23 14:26:19 gestor1 kernel: ip_conntrack: table full, dropping packet. The server is celeron

Hi, I am experimenting a little bit with my firewall and I don''t seem to get my head round marks ... I try to mark p2p packets generated on the firewall in the output chain and then try to match that mark either in NAT OUTPUT or POSTROUTING I don''t seem to get the expected result. Any help or clue would be more than welcome. root@droopy:~/firewall > iptables-view -t

Hi, I am not sure if this is the correct destination for this email question, so if not, please can someone direct me to the correct mailing list / user.

We have built it into your kernel, but are looking for some help in the matching parameters for skype in

Hi, my company have just bought new network and I have question about one problem. As in topic we must use few completely different dsl''s and balance traffic between them. 2M/0,5M 4Mb/0,5M 8M/0,5M M=Mb/s I''ve never done such thing before so I have doubts how it will work. If the links are symmetric 2/2 4/4 8/8 there is no problem because with weights I can compensate the

Greetings, I''ve searched, found ftwall, and some other commercial solutions, but am wondering if anyone on this list has any solutions using a linux firewall to block p2p traffic, more specifically Kazaa.

Hi all !!! I have a firewall bridge (not router) with two nics that filter p2p with ipp2p. All works fine but now I need to add a third nic to route all p2p traffic through this nic. It is that possible with a bridge ? Later (with other server) connect to this nic I do loading balancing with two adsl lines to route all p2p traffic. Any hint ? Any howto ? Thanks in advance. roberto --

Hello there, I''m having lots of problems with my setup here. Let me explain: I am network administrator for my university dorm. We are about 300 users, and we have 2 ADSL connections doing load balancing with 300kbits upstream and 2Mbit downstream. The load balancing is working great, we are doing connection tracking so I can mark and hence prioritize interactive traffic and ACKS

re I would like to do some firewalling and p2p shaping/limiting on one of the vlans in my network and I was thinking of using linux box as transparent bridged firewall/limiter. For this I''m planning to use AMD64 2.2Ghz box with 2 1gbit NIC (Broadcom 5721), that will be bridged. The box must be totally transparent and unseen in the network, as well as it should have much influence on

Hello, I guess a few of you know about the iptables-p2p project at the http://sourceforge.net/projects/iptables-p2p site. This suite has an excellent filter of which I use today and its running very smoothly. The main reason why I use this is because I desperately need to block torrents. IPP2P does not do this at this time (it seems to me in the doc at least). Is it maybe some way we could merge

Hello everyone, I want an opinion from people who tryed different matching modules to match diferent types of traffic, especially p2p ones. I would like to hear which scales better as CPU usage and latency : ipp2p, iptables-p2p or l7-filter with the p2p patterns. I want to use one of them to block most of p2p (except maybe dc++ and emule which i want to shape). I would use the matching rules in

Hello, I''ve been trying to shape the bittorrent traffic (on my external interface, upload), but without luck, for this I''m using layer7 filter right now, but I''ve also tried ipp2p, with the same results, I might say that this is not a problem with this packet classifiers, the problem is with HTB, here''s why. When I open azureus (the bittorrent client I

Hello list. I''ve configured a very simple script to slow down packets coming from a particular IP Address.
