Wireshark

What is Wireshark? To answer this it is best to quote the description from the Wireshark website.

Wireshark is a free network protocol analyzer for Unix and Windows. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing summary and detail information for each packet. Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.

Wireshark supports an enormous amount of protocols, but there are still a number of obscure protocols that aren’t used that often. But the users of those protocols would still be helped a lot if Wireshark supports those protocols, and so I started writing several Wireshark dissectors.

ACN

ACN is a protocol suit to control theater equipment, like lighting. ACN is currently under development and so the Wireshark dissector will also stay under development for that time.

Art-Net

Art-Net is a protocol used, for example, for things like theaters to transport lighting data over Ethernet. The protocol is designed by Artistic Licence and put into the public domain. The dissector supports all documented packets, but there are some undocumented packets that still have to be added (when I get the needed information).

RTNET

RTNET is a protocol for realtime Ethernet communication. It uses RTAI/Linux to provide true hard-realtime communication. To get a feeling on what RT-Net looks like you can download this tcpdump file and open it in Wireshark. For more information see the RTNET Homepage and the RTAI Homepage.
