There's always one thing I'll forget

This weekend I decided to finally move my server, networking gear, and printer into the computer room closet. I have multiple reasons to do this, reduce the noise and clutter, reclaim more deskspace, et cetera et cetera. But the biggest reason was that I just ordering one of those brand spanking new Mac Minis and I wouldn't be able to use my printer with it since the printer is a really old HP Laserjet 4 Plus with only a parallel port. So, I rearranged the shelves and got everything to fit, made sure the internet connection still worked, then tried to setup cups on the server so I could print through the network. Pretty quickly I was able to get it up and running where I could connect to it through a browser running locally on the server and being displayed remotely through Exceed. The first test page printed out perfectly. But then I spent like three or four hours trying to connect from my other computer. I tried everything: screwing around with the cupsd.conf file, trying to setup Samba instead, et cetera et cetera. Then, today, I finally realized that I had a software firewall running on the box (in addition to my hardware firewall in front of it) and that I hadn't allowed those ports through. Damn, it's always one tiny thing like that. Well, less than five minutes after that revelation I had port 631 opened up and Windows XP talking with cups.
