Can you try that also please. Also, to help track down performance issues I've modified the Makefile to build a profiled version of the application so you can use gprof(1) to figure out where any problems lie. Second, * the list is created once and no additions or deletions are * made during the lifetime of the program.

To use them as traffic shapers would require extra workon the sysadmin's part (scripts and other types of scotch tape).

The protocol patterns are from the l7-filterproject.Basically, you use ipfw(8) to divert tcp/udp packets to the damon. http://webinweb.net/unable-to/warning-stream-socket-client-function-stream-socket-client-unable-to-set-private-key-file.html How much of the 21Mbits/sof traffic is P2P?
