Tools for finding outbound and inbound connection patterns

[Al Schneider <alschneider67 () gmail com>]

Hi everybody,

I'm looking for an IP tables log parsing tool, or similar, that will
look for connection patterns, like say, for a user who is accessing a
host on a given port every three hours for example.
I'm sure it could be scripted in Perl or another language, but I was
wondering if anyone knows of existing tools for this.
Maybe its possible with Snort or Argus, but I can't find any specific
documentation yet that mentions this feature.
I might not be searching with the right phrases, because googling for
"connection patterns" and similar terms doesn't turn up much at all.

Thanks,

Al
