This should be a pure feature inside NetworkManager. So for Bluetooth it does work a little bit different than for WiFi or other technologies, because the profiles clearly define what needs to be done. And there are qualification tests to ensure this. The basic code in bluetoothd is present today, but we have to update the D-Bus API to actually match reality. I have talked with Luiz about it last time and I have the proposal here. Just need to push it and update the code a little bit. General idea is the following. NetworkManager has to create a bridge interface and provide DHCP and DNS servers on this bridge. After that it calls into bluetoothd via D-Bus and activates PAN server. Arguments are the bridge interface name and some authentication details. Then if someone connects over Bluetooth, a new bnepX networking interface will be created and added to the bridge by bluetoothd. That is basically it. And as a side note, nothing is stopping you to also use that bridge for WiFi or anything else. However in that cases normally the bridge in between is not required. With Bluetooth it actually is. Even if you can potentially start many DHCP and DNS servers and point them individually to every bnepX interface. I doesn't really follow the specification and you lose the capabilities of link local support between the clients. And we will not be exposing an API to access the individual bnepX interface manually anyway. Especially since the bnepX namespace is shared between clients and servers. In the end it is just an Ethernet emulation. If you look at the uevent for Bluetooth BNEP interfaces these days, you will see that they are clearly marked with DEVTYPE=bluetooth. And this reminds me that we might need to add some sort of UUID=nap/panu field to it to clearly distinguish the role of it. I have to look into this.

The code needed on the gnome-bluetooth side is one function, akin to the one in the gnome-bluetooth plugin for nm-applet to switch on PAN. It's more finding the time to write the NM code that's the problem ;) In the meanwhile, you can use pand on your "server". There's already pretty good pages on how to do that. On the connecting side, you can then use gnome-bluetooth to pair and enable the connection to that machine.

Where do we plug the NM code in? Did we figure out a place to put the "[X] Share my shit" checkbox, or is that going into the bluetooth applet somewhere? I think it's actually pretty simple on the NM side. Dan ___ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

Not quite yet, but we've got a feature request for it in bugzilla and I've already spent some time thinking about it and discussing implementation details with relevant people (Bastien, really). The general idea is that you'd just check a "share my internet connection over bluetooth" somewhere, which would poke NM to start up sharing over bluetooth like any normal NM ICS works. I have no idea when this would hit, since some of it depends on other UI components like gnome-bluetooth or kde-bluetooth.
