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.

TCP/IP over SMTP … RFC?

Via Flutterby this wonderful page about tunnelling TCP/IP over SMTP.

Yes, you read right—a way to tunnel TCP/IP over the SMTP protocol, which itself runs over TCP/IP. The author of the page states that this is for firewalls so restrictive that only email passes through. Issues of latency aside, is seems so … convoluted … to do such a thing.

But remember—the Internet sees censorship as damage and routes around it. Often times in ways people don't expect.


IN-ADDR.ARPA DNS

I've been helping someone setup DNS—more specifically, so he can control the reverse lookups. I use NS records but according to the documentation of BIND and RFC2317, you're supposed to use this horrible CNAME hack. The only thing I can think of for doing that, beyond the Complexity for Complexity's Sake Syndrome, is to avoid confusing a person over having to configure an IN-ADDR.ARPA domain they're not really delagated to serve.

I was told the trick by my friend Kelly who used it for his home network. He sat down and applied some thought as to how DNS works and came up with this method.

I like it better than the “official” way.


LASER Tag and an end of alphabet soup

Laser Tag. Much fun. Much pain. Ouch.

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.
