Hi Daniel, thanks for the ideas.
That was a misspelling (I typed it in, not cut & paste)
I swtiched to using sysctl.conf after reading that the
/etc/network/options is deprecated
Still the same problem.
I've resorted to a cron job that sets it to 1 ever minute.... quite a hack
so I'd love to know the real cause of the problem.
NOte that I didn't do a standard Edubuntu install, I had Edubuntu
workstation, and then installed LTSP, etc. on top of it. I imagine I have
a config missing somewhere.
