Finally got it working... Not the Debian way, but the udev way of things...

I have no bnep0 device no matter what I do and I tried what's in this thread, how do I make it appear? (I tried with bluetooth on, etc, but your script always says there is no bnep0, and when i do ifconfig bnep0 it says it doesn't exist)

bnep0 is created automatically on the N900 when you connect from your PC. Does the Bluetooth icon gurn blue when you establish the connection?

yeah it turns blue, I use the bluetooth DUN script fine for tethering, but I wanted to give this bluetooth PAN thing a try.

I can't find a bnep0 device no matter what I do though :/ not sure why

Thank you for giving it a try. Let's work it out together.

Regarding the bnep0, have you installed connectivity manager?

I might have missed this one in the instruction: bluez

Please install it and try again. ^^

Hi, sorry my n900 broke due to the usb port falling off, I just got my replacement today, and same problem as my old one! no bnep0. I'm going to try to see if i have bluez installed and tell you what happens

Just add before stand-alone command:

Code:

dnsmasq -I lo -z -a 192.168.1.1 -F 192.168.1.64,192.168.1.127

PS: tested and it works with Windows 7, but probably you'll have to renew dns lease:

Code:

ipconfig /renew "Name of PAN Adapter"

Per your suggestion the main script in 4.3.1 is modified accordingly such that IP and DNS can be assigned to client automatically once PAN is established.

Thank you very much for your kind help.

apparently i already had bluez installed, what do i do now

i tried hciconfig and it shows hci0 and when there's bluetooth activity the TX and RX increase in number, is it related to bluetooth?
