The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

More updates on the tarpit

Labrea is actually logging about half a gig a day. Over a 24 hour period (from about 6 am Thursday to 6 am today) I'm tarpitting 82,359 connections across 2,059 unique IP addresses (24,252 connections from a single IP address). And while the number of network ports being accessed has increased a bit, it's the Microsoft specific ports that are still the most popular targets (with 72% of the scans):

Top 10 ports captured by Labrea in the past 24 hours
Port # Port description # connections
Port # Port description # connections
139 NetBIOS Session Service 24941
445 Microsoft-DS Service 23013
1433 Microsoft SQL Server 6772
4899 Remote Administration 5620
135 Microsoft-RPC service 4722
80 Hypertext Transfer Protocol 3697
8080 Hypertext Transfer Protocol—typical alternative port 1686
7212 (unknown) 1683
8000 (unknown) 1471
10000 (some web based control panels use this port) 951

The program I'm using to generate the stats is written in Perl, and it took about 4 hours to run over a day's worth of data (the machine that does the tarpitting isn't the fastest machine we have, but it's more than enough to dedicate to just running LaBrea). I definitely want to write a program to process LaBrea data in real time.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
