It certainly sounds extremely interesting ... but how would you build graphs?
Are you talking about tethereal, with the "-z" argument, and io,stat filters,
or something totally different? I have been using tethereal for a while for
such things as statistics, but I had no idea about graphing capabilities ...
could you expand a little on this, please (share the syntax)?
Thx,
Stef
