Sky BB auto updates...

How to disable Sky Broadband's router's auto-upgrade .. at least until the next time you reboot it..

Unplug telephone line.
Restore back to 1.02.28 using the firmware image on the CD.
Use a URL injection hack to enable telnet.
telnet in!
ps -wax
look for "/usr/sbin/provisioning_ap"
kill it!

and for good measure:
nvram set "prov_last_attempt_time=2008-12-31 23:59:59"
nvram set "prov_last_update_time=2008-12-31 23:59:59"

although I yet don't know if this will actually stop it trying again.

Now you can plug the telephone line back in...
