Bluetooth and the p990i PAN and Ubuntu or Debian
Find your phone
sudo hcitool scan
Get the address of your phone something like: 00:19:63:ED:30:0F
sdptool browse 00:19:63:ED:30:0F
Will show you what your phone can do
Now install dnsmasq and stop the service as you don't really want to run a full dns and dhcp service yet!
sudo update-rc.d -f dnsmasq remove
Create a file /etc/bluetooth/bnep0.up and add script to startup dnsmasq
Script to run stuff as the network comes up
echo 1 > /proc/sys/net/ipv4/ip_forward
ifup bnep0 sleep 2
test -f /var/run/dnsmasq-bnep0.pid && kill
dnsmasq --pid-file=/var/run/dnsmasq-bnep0.pid \ --interface=bnep0 \ --localise-queries \ --dhcp-range=192.168.44.10,192.168.44.20,255.255.255.0
00:19:63:B4:52:01 - Bluetooth Mac address.
edit /etc/network/interfaces and add:
iface bnep0 inet static address 192.168.44.1 netmask 255.255.255.0 post-up iptables -t nat -A POSTROUTING -s 192.168.44.0/24 -j MASQUERADE post-up iptables -A FORWARD -i bnep0 -o eth1 -j ACCEPT post-up iptables -A FORWARD -o bnep0 -i eth1 -j ACCEPT
Note: It should probably add something about getting eth1 to be correct and also adding post-down to remove the firewall.
On the phone create a new bluetooth connection to the linux box and you are off.
