Acnode lockup

[solexious]

Been running an acnode on my home network for ~4days just pinging to check its status. Came in this morning to find it had gone into "no network/server mode" trying to make http requests to the server via a browser timed out and doing a ctrl+c managed to bring it back to life with a trace route spat out. (this also brought the acnode back to life)

KeyboardInterrupt

This is just because SimpleHTTPServer is single-threaded and there isn't a supervisor. Using Apache/wsgi will prevent this taking out the server, but the device still needs a watchdog.

[Jonty]

Could port it to eventlet/gevent fairly easily, which will allow for nonblocking polling of the device.

[marksteward]

Yup, that'll work too, but the device will still need a watchdog in case the network goes down.

[solexious]

Will work on bug that prevented use of the watchdog on the device

[marksteward]

Not a bug
