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

Hi there, I have a little problem. I had this some months ago but didn''t solve it back then. I have patched my kernel with Layer 7 support and patched my iptables to support it, too.

Hi, I have simple question about Skype. What are the methods of selecting packets which belongs to Skype?? I know about 7layer but I don''t belive that is only way.

I was wondering if anyone had implemented rules like this in shorewall: http://blog.andrew.net.au/tech I see tons of brute force attempts on the machines I administer, and I like the idea of limiting them without the need for extra daemons scanning for attacks.

Hello, First , thanks to Tom for it''s great job ! Netfilter is really easy and powerfull with shorewall. So, I have configured two firewalls whith shorewall using keepalived for the redundant VRRP stuff. FW-a is MASTER and FW-b is BACKUP. Everything works correctly and FW-b upgrade to MASTER when FW-a is down or disconnected. FW-b downgrade to BACKUP when FW-a comes back. But when I

Hello every one! I''m making a project to a discipline in the university and the project is make a Linux router that grants QoS to Multimedia connections (the prof. say we can use Open Source Soft. :) or reinvent the wheel). I have been googeling and googeling and i found the l7-filter in source forge and the spectacular simple language that is TCNG. Well the problem is how can i

Hi folks, A while back we had some discussions about integrating heartbeat and shorewall. Thanks to your help and the excellent state of Linux failover clustering, i''ve managed to install my high-availability firewall. I know there''s already a howto for it at http://www.xenos.net/library/hafirewall.html, but i thought i would document my setup for others, since it''s

hi everybody. im trying to set up an QoS config, using layer7 (http://l7-filter.sourceforge.net/) for protocol detection. im suposing 3 clients with this configuration: 3 clients: 1.2.3.1 , 1.2.3.2 , 1.2.3.3 1.2.3.1 has 256kbit bandwidth "guaranteed" clients 1.2.3.2 and 1.2.3.3 has 256kbit bandwith so im marking every packet using layer7 iptables module, classifying them in three

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 trying to shape traffic in a dorm''s network (4 mbit symmetrical internet link, about 200 computers, heavy p2p usage). The router is a p4xeon running linux 2.6.9 with the qnet patches (http://kem.p.lodz.pl/~peter/qnet/). When I activate ip_forward I get >20% packet loss and a lot of duplicates. Any ideas? I attach my shaping script. Thank you very much in advance,
