Hi folks,
I'm starting to use Bluez to create a PAN. I'm using the 2.6.x linux kernel.
I did the following:
####
GN:
####
Edited the file /etc/bluetooth/hci.conf and enabled the "lm accept,
master" option.
# hcid -f /etc/bluetooth/hci.conf
# sdpd
# sdptool add GN
# modprobe bnep
# pand --listen --role GN -n
####
PANU:
####
# hcid -f /etc/bluetooth/hci.conf
# sdpd
# modprobe bnep
# pand --connect BT_ADDRESS
After the connection establishment I configured a LAN with the 10.0.0.0/24 IP
configuration. So:
####
GN:
####
# ifconfig bnep0 10.0.0.1 netmask 255.255.255.0
####
PANU:
####
# ifconfig bnep0 10.0.0.2 netmask 255.255.255.0
At this point I could ping the two host:
####
GN:
####
# ping 10.0.0.2 # that's ok
####
PANU:
####
# ping 10.0.0.1 # that's ok
So, I tried to add a second PANU with:
# hcid -f /etc/bluetooth/hci.conf
# sdpd
# modprobe bnep
# pand --connect BT_ADDRESS
It connected with the GN, but when I tried:
# ifconfig bnep0 10.0.0.3 netmask 255.255.255.0
# ping 10.0.0.1
The ping could not reach the GN host even the other
PANU (ping 10.0.0.2). I tried to do a ping from the GN to
the new PANU and from the old PANU to the new PANU
and the problem kept.
What am I doing wrong?
Any help is very welcome.
cheers,
Eduardo Bezerra Valentin

The bridge is another virtual network card the combines your two BNEP
interface into a new one. This is of course not all a bridge can do, but
this is what you need. However this is not BlueZ specific. This is about
network administration and thus read a howto about that or take a look
at the PAN howto.

Hi all,
Thanks for the quick response. It's truth that I get a second bnep
in the GN, the bnep1. But
I tried to continue the configuration with a "ifconfig bnep1 10.0.0.4"
and the problem kept.
I thinked that at this point (with the two PANU connected and
configured), I could ping
the bnep0 with the old PANU and ping the bnep1 with the new PANU, even
without the
bridge configuration in the GN.
Ok, and how can I do a bridge configuration in the master ??
Is it just creating statics routes between the two bnep's?
Thanks a lot,
Eduardo Bezerra Valentin

this is correct. The latest pand and dund version add the SDP record
unless you call them with --nosdp.

Sorry if I'm wrong but i think the newest version of pand do the sdp
stuff (you don't need sdptool add GN)
Please correct me if I'm wrong ...

you will get a second (bnep1) interface on the master machine and thus a
bridge is needed to connect these.
