Apparently, one of my servers has been running for more than eight years between restarts:
Look, mea culpa and all that.
I've been far, far too busy (and far, far too self-important) to write anything for a while, so I've decided to just throw something up here quickly to sum up what I've been doing most recently.
Leopard and Tiger (10.5 vs 10.4) do things differently, particularly security-wise. I've been tinkering around with a little script to open an SSH session between a client and server, then tunnel AFP through it. Thus, no need to open port 548 to the outside world (unspeakably bad idea), or mess around with tiresome VPN shenanigans.
If you understand that last paragraph, then you'll agree that it's pretty neat.
If you don't understand that, then clearly you're a person who actually does something useful and valuable with their life, and probably doesn't spend a significant chunk of your time looking at a command line and occasionally uttering salty oaths. I salute you.
