One thing to note, is that it is a whole lot harder to fix problems when you don't have Internet access. This is the first time I've ever regretted not putting a modem in that box. Although, Internet access via a modem is hardly worth it anyway. I'm considering getting myself the cheapest token ring adaptor I can find, and taking my box in to work to fix.
I think a good 'apt-get update && apt-get upgrade' would likely solve a number of my problems. ;-)
And, even if it doesn't fix anything, it'd make me feel better. ;-)
It would also make me feel a little more sure about shipping it back home to it's static IP.
