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.

Anyone up for hyperlinked network maps?

Along with setting up NTP and SNMP on all the servers here, I've also been documenting the network here at The Company (not that Dan hasn't done that, but he's responsible for the overall network and tends to focus on the switches and routers—I've been concentrating on the hosts I manage plus the switches they're hooked into). In doing this, I came across a drawing program for Unix called Tgif, an Xlib based (woo hoo! no huge external libraries to worry about! Yea! No insanely large amount of dependencies! Woo hoo!) interactive 2-D drawing program.

I've spent the past few days with it, drawing the network—the rounded rectangles are network switches (the one in the upper left has two VLANs, one with 18 ports in green, and a second one with 6 ports in blue), the larger black squares are computers. Red squares designate off-page (as it were) connections. Red lines designate switch-to-switch connections. The purple square encloses the office machines and the turquoise squares are some comments about the two upper switches (yes, the image is shrunk).

But it was only when I was writing this entry did I realize that Tgif has hypertext capability (has since 1994! Ken! Why didn't you find this program?) and I've been going through the demo pages with the Tgif program since (and want to go back actually … so … um … end of entry).

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.
