autowol
automatically turns on a local computer when needed
... it on. Doing this manually is unpleasant when one is used to systems being available round the clock, so I created autowol to help. As soon as I want to access my NFS server, autowol detects that it is down and sends a WOL (Wake-On-LAN) packet to turn it on. My NFS server boots up in under 15s, so the lag is very reasonable.
