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.

Mysterious packets in the night

For about a decade, I've been monitoring syslog traffic in real time. It makes for an interesting background screen. For instance, I've noticed over the years Mac OS-X getting more and more paranoid about running executables. that one UPS needs a new battery, and just how many DNS requests Firefox makes. Just stuff I notice out of the corner of my eye.

So it was rather alarming when I just saw the following pop out:

iTunes  tcp_connection_destination_perform_socket_connect 140 connectx to 2600:1403:b:19a::2a1.443@0 failed: [65] No route to host

Now, I have IPv6 enabled on my Mac to play around with the technology, but my main connection out to the Intarwebs is still plain IPv4. So that explains the error. But the question is why is iTunes trying to connect to some machine on the Intarwebs? I have iTunes running, but doing nothing at the moment.

So then I look into that IPv6 address. First, it's assigned to Europe, which is odd, because I'm not in Europe. Second, it seems it belongs to Akamai Technologies. So the bigger question now is, what is iTunes trying to get from Europe? Is my computer trying to snitch on me? Checking for updates? Is iTunes feeling neglected?

I don't know … and that is bothering me.

Obligatory Links

Obligatory Miscellaneous

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: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

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.
