I do essentially the following to provide IP connectivity over bluetooth
to my Palm:
: ${rfdevice:=rfcomm0}
sysctl -w net.ipv4.ip_forward=1
sdptool add --channel=1 SP
rfcomm --encrypt watch "$rfdevice" 1 pppd '{}'
"${localIP}:${bluetoothIP}" local nodetach noauth proxyarp $dns
This is with a recent BlueZ 4.x rfcomm. I'm using an old kernel, which
has terrible bugs that are hopefully resolved in newer kernels (if I
disconnect from the Palm end before the Linux end, rfcomm seg faults
[might be a user level bug there] and I need to reboot in order to be
able to reconnect again).
