No, the scan detector isn't in there yet. We're planing to rewrite it
using the new frameworks, but than didn't make it into 2.0 anymore.
We have however ported the 1.5 version over to Bro 2.0 and put it into
the contributed scripts repository for now, see here:
You can download scan.bro from there, put it into your site directory,
and then load it from local.bro. The script hasn't seen much testing
yet, but it's basically the 1.5 version with a few little pieces
updated to the 2.0 API changes.

The easiest way would be without any trace at all, just some lines of
script code directly triggering an alarm. There are a few tests in the
test suite which do that. Try this:
Then look at notice.log.
