How to fight with encrypted p2p
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. Pozdrawiam Szymon Turkiewicz

Problems with HTB. Help!
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

LoadBalancing on many asimetric different dsl''s.
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

Modifying traffic shaping rates according to the amount of active users
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

Detecting p2p 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

bridge and ipp2p question
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 --

elementary usage clamping
I''m pretty smart, and was once regarded as pretty network and computer savvy. But the world has obviously passed me by! I have a server in a colocation facility, and I was recently hit by a bill for overage; I used more bandwidth than I expected, and I must pay. So now, I want to bother with packet shaping on the server. The *most* important thing is to clamp bandwidth to the 1Mbps

NAT-aware traffic analysis
I have tried using iptraf for my NAT firewall to analyse the IP traffic. Basically I am faced with this difficulty of related the source IP to the outgoing interface to the internet, so I am wondering if anyone has a suggestion for a different ways to do it, or a suggestion for a better tool. Details :- Supposed : eth0 - LAN eth1 - WAN1 eth2 - WAN2 And then

Token Bucket Filter and Dropping
I am trying to create my own Token Bucket Filter. However, I have a problem with packet dropping. Scenario : I got two streams 20KB/s each. I got one bucket with rate 20KB/s I put both streams into this bucket. When buffer is full packets need to be dropped. The problem is that only every other packet needs to be dropped in this scenario. Streams are the same so queue looks like that : S1 |

Modems: Cable or DSL digital blunders that lartc may help with.
I have a Cable ''modem'' that has a problem that many of these devices is bound to have. I was wondering what other lartc user thought about this and if DSL has simular problems. Cable, being Asymetrical, is able to upload at a given rate and hopefully has a buffer, in the modem, of some kind. When I nc(netcat) to a UDP echo, or discard, server I get about 10Mbps out on my
