hi, kids. a client of mine is interested in a blisteringly fast, 1-day course in the state-of-the-art in open source linux-based network analysis (and related) utilities. off the top of my head, i'm thinking: * netcat * tcpdump * nmap * wireshark * ntopng and lots of other easily-installable commands like: http://www.binarytides.com/linux-commands-monitor-network/ it's just a matter of deciding how much i can cram into a single day. any recommendations from the masses as to what people are using and what works for them? i realize this is an open-ended request, so you're welcome to free associate. rday -- ======================================================================== Robert P.
