Preliminary Ethereal User's Guide
An Anonymous Coward writes "The prelimiary Ethereal User's Guide is up.
It will be updated over the next month or so, and will be followed by a Developer's Guide.
It is all done in DocBook and the source will be up at the Ethereal web site." If you haven't used ethereal, its an extremely excellent packet sniffer: play with it a little and you'll never use telnet and FTP again (unless of course you knew that already).
A great resource that I refer to alot:
