[Bluez-users] PAN connection: palmtop -> linux -> internet

[Bluez-users] PAN connection: palmtop -> linux -> internet

[Grzegorz]

Hello!
I have searched may post but I couldnt why my connection is not working.
I had tryed many configurations like on this sites:
http://bluez.sourceforge.net/contrib/HOWTO-PAN
http://fedoranews.org/contributors/muhammad_al_ismail/bluetooth/

My hardware:

Linux kernel 2.4.27
Bluetooth dongle D-Link DBT-120
Palmtop Siemens LOOX 600 with Windows Mobile 20003

hciconfig -a gives this:

hci0:   

Type: USB
BD Address: 00:0D:88:AC:CB:6A ACL MTU: 192:8  SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:99 acl:0 sco:0 events:13 errors:0
TX bytes:296 acl:0 sco:0 commands:12 errors:0
Features: 0xff 0xff 0x0f 0x00 0x00 0x00 0x00 0x00
Packet type: DM1 DH1 HV1
Link policy: HOLD SNIFF PARK
Link mode: MASTER
Name: 'Linux'
Class: 0x000100

HCI Ver: 1.1 (0x1) HCI Rev: 0x20d LMP Ver: 1.1 (0x1) LMP Subver: 0x20d
Manufacturer: Cambridge Silicon Radio (10)

hcitool scan easy finds my palmtop Siemens LOOX 600:
Scanning ...
        00:E0:00:C8:1C:65       LOOX

... and now I want to have internet access on my palmtop. I can
connect to Linux using palmtop.

When I reboot Linux I'm writing this to make BT connection and
services working:

modprobe hci_usb
hciconfig hci0 up
hcid
sdpd
pand -s -M --role=NAP

I configured everything on palmtop and when I try to connect to
Linux using PAN in /var/messages is showing:

Dec 16 20:59:12 router_nnd hcid[11147]:
link_key_request (sba=00:0D:88:AC:CB:6A,dba=00:E0:00:C8:1C:65)

Dec 16 20:59:12 router_nnd pand[6330]:
New connection from 00:E0:00:C8:1C:65 bnep0

.. and now is the problem. After few seconds after connection a
window on palmtop is showing with this message:

Unable to obtain a server assigned IP adress. Try again later or
enter an IP address in Network settings.

So .. I tryed some configurations in dhcp but they didnt worked.
Can someone help me? I think that I'm near of making it working
but I tryed almost every possibility I know.

Regards and thank You for Your help

enable the rswitch and use accept,slave as link mode.

It seems that you need to run a DHCP server and maybe you need to create
a bridge for all incoming PAN connections.

Thank You .. I dont know why I had not looked into those howtos ..
but now I have another problem .. when my palmtop connects to Linux
after a while I'm disconnected from internet on my palmtop and on my
desktop computer .. when I try to ping my Linux server I have timeouts
and only hard reset helps me. I looked in /var/log/messages .. errors
and kernel and I couldnt find anything related to this problem .. this
could be a problem with a iptables? My LAN network is 192.168.0.0 and
network for palmtop is 192.168.1.0.

Thank You for Your time
