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

• TCP: Qod uses TCP as its transport protocol. The TCP port for qod traffic is 17.

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.

• SampleCaptures/qod.pcap

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
