Earthworm Module: sniffring
Contributed by: Lynn Dietz at USGS, Menlo Park
Function
Latches onto a user-defined transport ring, reads every message and prints logo to screen.
Details
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 [-n] Usage 2: sniffring [-n] Usage 3: sniffring [-n] verbose Usage 4: sniffring [-n] verbose Sniffring shows full ring, inst and module names if 'v' or 'verbose' is specified as the final parameter. Otherwise you'll see numeric IDs for these three, as defined in earthworm*.d files. (Modules from external installations are not identified other than by number.) A new option is -n to not flush the ring of all messages first, must be before ringname if used the default is to flush the ring of all messages and only show those that come in after invocation
