Re: [Bluez-users] pand seem to ignore any pin configurations

[Rainer Dorsch <rdorsch@web.de>]

Hi Marcel,

thanks for the quick reply. Where would I specify the PIN on the PANU? Should 
pin_helper in hcid.conf provide this? Where would I specify the PIN on the 
NAP?


There is no --auth for pand:

silverboxy:~# pand -h
Bluetooth PAN daemon version 2.15
Usage:
        pand <options>
Options:
        --show --list -l          Show active PAN connections
        --listen -s               Listen for PAN connections
        --connect -c <bdaddr>     Create PAN connection
        --autozap -z              Disconnect automatically on exit
        --search -Q[duration]     Search and connect
        --kill -k <bdaddr>        Kill PAN connection
        --killall -K              Kill all PAN connections
        --role -r <role>          Local PAN role (PANU, NAP, GN)
        --service -d <role>       Remote PAN service (PANU, NAP, GN)
        --ethernet -e <name>      Network interface name
        --device -i <bdaddr>      Source bdaddr
        --nosdp -D                Disable SDP
        --encrypt -E              Enable encryption
        --secure -S               Secure connection
        --master -M               Become the master of a piconet
        --nodetach -n             Do not become a daemon
        --persist -p[interval]    Persist mode
        --cache -C[valid]         Cache addresses
        --pidfile -P <pidfile>    Create PID file
silverboxy:~#

Do I need 

        # Authentication and Encryption (Security Mode 3)
        auth enable;
        encrypt enable;

in the device section of /etc/bluetooth/hcid.conf?


When I do have them and the --encrypt option for pand on the NAP

rd@silverboxy:~$ ps uaxwww|grep pand|grep -v grep
root     15840  0.0  0.1  1548  536 ?        Ss   23:32   0:00 /usr/bin/pand 
--encrypt --listen --persist --role NAP --pidfile /var/run/pand.pid
rd@silverboxy:~$ 

I still get pinless authentification (or they somehow match, though I tried to 
make them different in all files).

Thanks,
Rainer
