-----Original Message----- From: Aengus [SMTP:Analog@eircom.net] I did all this with command line tools, and most of the time was spent just reading through the 433MB for data. If I really wanted a host count for each hour, it would probably be a fairly trivial task to write a script that would do a host count at each hour transition, getting all 168 host counts in a single pass. It would run in less time than it's taken to read this thread (and it probably wouldn't take much longer for a competent perl programmer to program it - I could probably do it myself in a couple of hours if I wanted it, and I even had to look up the little bit of perl that I did use).
