I got curious about how NM-0.7 works so I installed it on olpc3-17 by:
sed -i -e '6s/enabled=0/enabled=1/' /etc/yum.repos.d/fedora.repo
iwconfig eth0 mode managed essid 'media lab 802.11'
killall dhclient
dhclient eth0
yum -yt --nogpgcheck update NetworkManager
/etc/init.d/NetworkManager restart
Then, with help from Michael Biebl and Rob McQueen, with two important
pieces of documentation
http://debs.michaelbiebl.de/network-manager/spec.html
http://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-properties
and with the excellent interactive IPython shell, I was able to create a
silly script which uses the NM-0.7 interfaces to list visible access
points. I present it on the off chance that it might serve as a helpful
introduction for other people who would like to help us port the Sugar
UI to the new API (or who would like to change NM-0.7 to better support
our hardware and networking configuration.) The script is attached.
Regards,
Michael
