[tkined] Capturing and Analysing Data from HP LANprobe

I have written a script to setup capture filter on a HP LANprobe III,
capture data packets and then analyze the packets.

I have setup a tkIned based network monitoing station with the standard
stuff (IP monitoring - Reachability, SNMP Monitoring - Router IF Load
etc) and the extension I have written. When the router interface load
exceeds certain limit (98% etc), the MoJoAction will fire up the
HP-Lanprobe (The one I am talking about) Interpreter and, setup a
capture filter on the proper HP Lanprobe III to capture data to-and-from

the Router on the LAN (approx Interface traffic) and generate 2 stats.
One stats is about protocol distribution and other is a distribution of
(Source_IP, Dest_IP, Protocol Used) trio.

Sorry, my tcl programming experience is only 4~5 weeks, so the code
definitely reflects that. But if anyone interested, can send me a email.

I tried hard to use the GRAPH object to produce some colorfull graphs of
the report. For some reason, I can't get the GRAPH to work properly with
blt. I would appreciate a bit of help on this regard. I am using tcl7.6
and blt2.3 on linux 2.0.0.
