(This will mean I can't tunnel home, because it's my domestic SSH server, and I therefore won't be able to connect to any of the other servers at home while I'm away. Also this machine is my main file server for random crap I need to dump somewhere temporarily, and the server onto which I back up /home/dougs from the laptop. If I need to get at any of those files in a hurry it'll mean getting those disks out and plugging them into something else. I've moved domestic DHCP and DNS back onto the router. Also it's my big-files-download client, so I'm very glad this didn't happen while Doctor Who or Torchwood were being transmitted.)
Fortunately my email is hosted on a different machine, and is unaffected. Also the Stepson has his own server, so he's likely not to notice.
