[Bluez-users] problems with network via bluetooth

[Aldo Maggi <turms@ciaoweb.it>]

my home lan is made up with three desktops.
one of them (GW) has 3 eth cards the first one links to the router
the other 2 connect PC1 and PC2 to GW.
PC1 has 2 eth cards, the first one links it to GW and i use the second
to connect, from time to time, my notebook (NB) to the lan.

recently i have bought 2 bluetooth/usb adapters because i wished to
create a bluetooth net between PC1 and NB

in PC1 i have Ubuntu Gutsy (but i have the problem i'm going to tell
also with Debian Lenny which is installed in PC1 as well) and in the
NB i have Debian Lenny.

the two bluetooth systems see each other:

if i run in the NB:  hcitool scan
correctly get:
11:11:11:11:11:11   paperino-0
 
the same in PC1:
00:15:83:B3:D3:9A    paperinik-0

in PC1 in the /etc/bluetooth/hcid.conf i have the line:
lm accept,master;

in NB in the same file:
lm accept;

in PC1 i run:
pand  --listen --role NAP

in NB i run:
pand --role PANU --persist --search

and i can read in the relevant /var/log/daemon.log the following:
in PC1 - pand: new Connection from 00:15:83:B3:D3:9A bnep0
in NB - pand: Connecting to 11:11:11:11:11:11
        pand: bnep0 Connected

then i run
in PC1: ifconfig bnep0 192.168.6.1 netmask 255.255.255.0
in  NB: ifconfig bnep0 192.168.6.2 netmask 255.255.255.0

and i can read in the relevant /var/log/daemon.log the following:
in PC1
Jun  2 18:15:59 paperino avahi-daemon[4819]: Joining mDNS multicast
group on interface bnep0.IPv4 with address 192.168.6.1. 
Jun  2 18:15:59

Jun  2 18:19:53 paperino
ntpd[4885]: Listening on interface #8 bnep0, 192.168.6.1#123 Enabled

and in NB
Jun  2 18:17:07 paperinik avahi-daemon[2750]: New relevant interface bnep0.IPv4 for mDNS.
Jun  2 18:17:07 paperinik avahi-daemon[2750]: Joining mDNS multicast group on interface bnep0.IPv4 with address 192.168.6.2.
Jun  2 18:17:07 paperinik avahi-daemon[2750]: Registering new address record for 192.168.6.2 on bnep0.

the 192.168.6.0 net on bnep0 is correctly shown by netstat -nr in both
PC1 and NB

but if i do ping from one machine the ip of the other i get Destination
Host Unreachable 

where do you think i'm wrong?
thanks
