Keeping the riff-raff out

Yeah, I finally got tired of watching überl33t h@XX0rZ¹ try to break into my ftpd and sshd.  So, after some dinking around with pf (which had the additional benefit of me growing slightly stronger in the fu of pf, learning a detail I hadn't picked up on before), I'm now allowing ssh and ftp connections only from pre-authorized hosts.  If you ever have a reason to ssh here, and you're not already authorized, you'll have to get in touch with me and get the host you want to connect from authorized.  (This pretty much only applies to ilcylic and wolfspaw at this point.)
