Layer 7 packet classifier doesn''t recognize packets sent by the router itself
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.
Now I inserted this line in my firewall script on my router for testing
purpose:
$IPTABLES -t mangle -A POSTROUTING -o $INET_IFACE -p tcp -m layer7
--l7proto http -j DROP
It works, BUT only if the

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.

How to select Skype traffic??
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.
Is 7layer realy good and stable solution for routers which must handle more
than 1000 users ?
Thanks in advance

Packet loss with htb+sfq+l7filter
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

>20% packet loss and a lot of duplicates. Any ideas? I attach my shaping

Matching with Layer7 vs. IPP2P
Hi,
can anybody comment on the cost of matching with IPP2P vs. Layer7.
Also, does a iptables rule with more complicated matching mechanism also
slow down processing if all the packets are matched before they reach
the rule. I.e. is the mere existence of a potentially costly rule
already slowing down processing or only if packets are actually
processed by it?
Thanks very much in advance.

New L7-Filter patterns for Kademlia / eMule?
I had been using L7-Filter[1] successfully for edonkey/eMule traffic until
