Installation

As we use BlueZ 3.x you will need to install the following package: bluez-compat

$ sudo apt-get install bluez-compat

BlueZ 3.x compatibility binaries. This package provides the legacy binaries that were reminiscent of the BlueZ 3.x pairing methods...
The provided binaries are: hidd dund pand

Usage

• Configure APF as "server":

# modprobe bnep
...
# pand --listen --role NAP

• Connect Host PC:

$ modprobe bnep
$ hcitool scan
Scanning ...                                   
        00:19:88:xx:xx:xx       APF
$ pand --connect 00:19:88:xx:xx:xx

• Check connection is done on APF

# hcitool con
Connections:
        > ACL 00:19:0E:06:44:45 handle 42 state 1 lm SLAVE
# ifconfig bnep0
bnep0     Link encap:Ethernet  HWaddr 00:19:88:xx:xx:xx
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

• Fix IP adresses on APF and on PC:

# ifconfig bnep0 10.1.0.1

$ ifconfig bnep0 10.1.0.2

• Check it is working:

$ ping 10.1.0.1
PING 10.1.0.1 (10.1.0.1) 56(84) bytes of data.
64 bytes from 10.1.0.1: icmp_seq=1 ttl=64 time=43.9 ms
64 bytes from 10.1.0.1: icmp_seq=2 ttl=64 time=13.2 ms
...

# ifconfig bnep0

          inet addr:10.1.0.1  Bcast:10.255.255.255  Mask:255.0.0.0

          RX bytes:826 (826.0 B)  TX bytes:1022 (1022.0 B)

• If you have sshd running on the APF and created the guest account then you can try:

$ ssh guest@10.1.0.1
