[Bluez-users] PAN over bluetooth - no TCP/IP activity

[Stefan <stv_vt@yahoo.com>]

Hello,

I'm trying to create a PAN between a laptop and a desktop computer. 

I carefully followed the instructions for creating a PAN network
(http://bluez.sourceforge.net/contrib/HOWTO-PAN).

Right now I am able to connect, ending up with correct and configured "bnep0"
interfaces on both computers.

The problem is, that I can not even ping them. After a lot of tries, I figured
out, that if I put the bnep0 interface in promiscuous mode, using 

ifconfig bnep0 promisc (at the NAP side)

then ICMP packets starts flowing, and the both nodes are able to ping each
other. But that's all. 

On both nodes hcid & sdpd are running, bnep module is loaded, kernel version is
2.6.16 (Fedora Core 4), bluez-utils 2.15

Here is what I do:

@NAP: # pand -s -r NAP
@PANU: # pand -Q -r PANU -d NAP
@Both (after a while): # ifconfig bnep0 10.0.0.x netmask 255.255.255.0 up
@both: # ifconfig bnep0
bnep0     Link encap:Ethernet  HWaddr 11:11:11:11:11:11
          inet addr:10.0.0.x  Bcast:10.0.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:6 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:478 (478.0 b)  TX bytes:64 (64.0 b)


Accoring to all docs I read, at this poing both nodes should be able to ping
each other. But they are not!

I don't know how important is, but just in case, here is the output of

# hciconfig hci0 -a
