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.

The millimeter waves of space

So sweet. Rob lent me his Cisco Airo 340 (a wireless PCMCIA network card) since he's not really using it right now; he was using it at work but they shut down the wireless network there.

I pulled down the latest version of the PCMCIA Linux drivers and started compiling. When loading the Airo module it kept complaining about unresolved symbols. Now, I'm compiling the modules under Linux 2.0 (they compiled fine) but I'm guessing some subtle changes have been made. I found the required symbols (under 2.0.39 they're inline functions), added the include file (<linux/isdnif.h>) to airo.c and that solved that problem.

The next problem: verbosity.

Since my laptop is rather limited in memory, I don't really run much, so any messages the kernel prints gets dumped to the console, and this driver is rather chatty. Annoyingly so. So back to the source code, comment out the messages, and we're good to go.

I had ssh1 installed but since there are issues with it, I decided to go ahead and install OpenSSH (since I already have it compiled for Linux 2.0). That was harder to get working than getting on the network. Regenerated the keys three or four times (on this laptop, that's not a fast operation), installing PAM, playing with configuration files and all it turns out to be is a permission problem on /dev/tty. Sigh. I still have problems with scp (secure copy—I keep getting “protocol error: unexpected <newline>”) but I'll solve that soon enough.

But this wireless network is soooo sweet. The ability to walk anywhere (well, within a few hundred feet) and still be online. So I can now sit out in the courtyard and work, or (like I am now) hanging out with Rob as he sets up a file server for the Facility in the Middle of Nowhere and watching Junkyard Wars and still being online.

But then again, you knew I was a geek to begin with.

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.
