donut is dead; long live the donut
I came home last night to discover that we had no network at home, and that the hard drive and CD-ROM lights on trusty old donut were blinking steadily. I hoped a therapeutic reboot might help, but after being powered down hitting the power switch again only resulted in a brief flicker on the power LED, nothing more.
I was able to recover into the new-donut project pretty quickly, surprisingly. I needed to install a newer version of OpenWRT on to the WRT54G ("commodity MIPS little-endian Linux box with built-in 802.11g AP"), and it did what I needed in terms of getting basic NAT up for the house almost out-of-the-box.
The one remaining thing is getting the magic tunnel network back up. OpenWRT doesn't have the Linux ipip kernel driver, but it does have Openswan packages, so I'm trying to set up an ipsec tunnel instead. This feels like it will work once I get the routing issues hammered out, which involves remembering the magic I had set up on donut before it died...
