search for: layer7

I''ve compiled my kernel (2.6.12.3) and iptables (1.3.3) and now -m layer7 option from iptables works (i don''t get any error when run the iptables command with -m layer7). The problem is that no packet is matched. For example iptables -A INPUT -p tcp -m layer7 --l7proto http -j ACCEPT doesn''t match http packets. The same for dns and ssh. So, what am I do...

hello, I try to use layer7 filter to classify packets. I have a proble with http match. This protocol seems to work well with l7-filter (http://l7-filter.sourceforge.net/protocols) but for me nothing is filtering in http class. Someone can help me ? Here is my script : #!/bin/bash IPT_BIN=/sbin/iptables TC_BIN=/sbin/tc INT...

Now I would like to use layer7: iptables -t mangle -A PREROUTING -s 192.168.0.0/24 -m layer7 --l7proto http -j MARK --set-mark 1 iptables -t mangle -A PREROUTING -s 192.168.0.0/24 -m layer7 --l7proto ftp -j MARK --set-mark 2 Do not work. An iptables -t mange -L -n -v does not show traffic on the MARK rules. But if I do this w...

Hello I''ve setuped a QOS bridge under debian 3.1 using 2.6.18.3 kernel + iptables 1.3.6 I''ve patched the kernel an Iptables with esfq+layer7 without problems. This simple script doesn''t log nothing ... And I''m sure to have eMule traffic (I''ve checked with tcpdump ) If I remove " -m layer7 --l7proto edonkey \" line I can see iptables log in /var/log/kern.log I''ve test with other...

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 use) I see upload traffic getting shapped, but also I see...

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...

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? Th...

...d 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 connection is established by a pc BEHIND the router (the connection is blocked). If I try to establish a http connection from the router itself it works completely (layer 7 is NOT working, the connection is working, thats what I wanted to say *g...

Please Advise me, Now I have got a problem about … Finding Tools In Linux (Opensource) that Can capture traffic packet and save it in log file or trace file. But it can classify Layer7 packet too Because I need to implement application that count number of packet in each application after packet pass through linux box which be like traffic control Please advise me. Ps. Can snort classifies Layer7 packet? Ps. I have just read on paper about ip table command they tell it has...

Hello I am looking for a way to have snort to dynamically update my shorewall config. I have seen software out there but I would like to see if anyone had tried this first. Aslo I would like to know if there is a way clear the Netfilter tables when I do a shorewall restart. The reason being is that when I make a change to my firewall setting I want all connections to have to re-establish
