[] My new (old) firewall/webserver/cvs-server box
So from the looks of it, I just succeeded in setting up WordPress on my old (new) firewall box. Some more info on that box as soon as I can find a decent utility to compose a summary of the box by itself, for now suffice it to say that it plays firewall, cvs-server and webserver at once, and my normal desktop hangs off a second NIC on the box (with a bit of help from a crossover cable).
I have one other thing to add: thanks to Samuel Sieb, I now know of the existence of WinSCP. It’s a windows client to connect to a machine using SFTP or SCP as desired. It’s very userfriendly, installation was smooth, and I transferred files without any trouble whatsoever. Which is great, of course.
