PIPACS

The program shows the IP traffic summary or the IP address pairs traffic and the traffic flow over the different TCP/UDP ports in real-time, with variable refresh time. You can filter for the interface(s), IP range, ports and protocolls. The captured data can be save to file and this captured data can be handle in external programs, which pipacs automatically starts. There are two different modes, one run-time summary and a protocoll capture/decoder mode.
The program were written originally from an Platform SDK sample to use the WinSock2 (Windows 2000) interface. Because of it usefullnes I ported it to Linux. The two version are not strictly the same because of the differences in the socket and the interface handling, but the outlook is the same in both case. The usage of the program ( in parantesis is the default values) :
Windows 2000Linux
usage: pipacs.exe options
where options:
[-c:sec] Dump cycle in sec (10)

Errors and todos

- LINUX :signal handling missing (^c -> promisc. mode setting back to original)
- LINUX : you can give just an ethernet interface (MAC protokoll decoder); TUN adapter: -v:-14 !!
- WINDOWS : you can select just one interface at a time
