Sniff Packets

mod_iptos can set IPTOS values on outgoing packets to assist traffic shaping. I wanted bandwidth control for a few virtual hosts, but i did not like the userland methods -- they were inaccurate and buggy. I wanted to take advantage of the linux kernel traffic shaping which i was already using...

Layer-7 Packet Classifier for Linux is a classifier for the Linux kernels Netfilter subsystem that identifies packets based on application layer data (OSI layer 7). This means that it can classify packets as HTTP, FTP, Gnucleus, eDonkey2000, etc, regardless of port. Our classifier complements...

libnetfilter_queue is a userspace library providing an API to packets that have been queued by the kernel packet filter. libnetfilter_queue library is is part of a system that deprecates the old ip_queue / libipq mechanism. libnetfilter_queue has been previously known as libnfnetlink_queue..

Another aspect of enumeration of hosts is the determining of TCP ports in an OPEN state, that is to say TCP ports which respond to SYN packets with a Syn and the ACK flag set, Syn-Ack. Synscan is impressively fast at determinining this via the use of two processes, one to send the Syn packets...
