Sniffring Overview

(last revised 1 June, 2006)

Sniffring is a command line debugging tool that latches onto a user-specified transport ring and reads every message on that ring. It prints to screen the logo, sequence # and length of the message, followed by the message itself (except for binary waveform messages).

`Usage 1: sniffring <ringname>
Usage 2: sniffring <ringname> <instid> <mod> <type>`

Sniffring was developed by Lynn Dietz at USGS, Menlo Park.
