Quote of the day (qod)
The qod protocol allows a client to get a random quote from a server.
History
The protocol is as old as TCP and is part of the basic protocols.
Protocol dependencies
Example traffic
Do'h - Homer Simpson
Wireshark
No qod dissector exists; the protocol is raw text without any formatting or commands.
Example capture file
XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
Display Filter
A complete list of qod display filter fields can be found in the display filter reference
Show only the qod based traffic:
qod
Capture Filter
You cannot directly filter qod traffic while capturing. However, if you know the TCP port used (see above), you can filter on that one.
Capture only the qod traffic over the default port (17):
tcp port 17
