I am sorry for the previous empty email.

I am using bluez4 on my pxa310 handset platform.
and I need to present dial-up network profile for my handset.

after I run "dund --listen --dialup --msdun --nodetach"
then, on my windows pc, using "IVT BlueSoleil",
I can find the dial-up service present by my handset.

but i cann't connect to the dial-up service by using BlueSoleil from my pc.

so, my problem is : how to config dund daemon for handset/mobile phone ?
thanks in advance !

Best regards
yesir Yao.

why nobody reply my mails ? :-)

hi, all developer:
   Does bluez4.x implement the "Dial-up Networking Profile (Gateway)" ?
   in my pxa310 handset platform, ttyS0 is bluetooth chip, ttyS1 is a
gsm moderm.
now, I want to implement DUN (gateway) on my handset platform.
It is to say : pc(ppp) --> handset --> gsm (gprs) --> net
I have look through the bluez4.x/compat/dund.c,
and found it cann't meet my requirement.

is it right or not ? and how to fix it ?

thanks again !

Best regards
yesir Yao.

I'm afraid dund is obsolete in Bluez 4. I think the right way to do it
is to use rfcomm to create a serial device like /dev/rfcomm0 and use
pppd to dial-up through that. I've only done that with Bluez 3 though
so I could be wrong.

I think, It is on the Data terminal side, not for the Gateway side.
the profile looks like:
pc (Data terminal : run pppd and dial to /dev/rfcomm0 )
--> handset (Gateway : with bluetooth chip and modem on tty)
--> gsm (gprs) --> net

now, i want to run "dund --dialup --msdun" on handset,
and receive ppp packet from pc, then send those to modem(ttyS1).

maybe, I must implement it by myself. :-)

Okay, I had a feeling you meant that. I've only set up a NAP gateway so
I can't help you there, I'm afraid.

I do essentially the following to provide IP connectivity over bluetooth
to my Palm:

: ${rfdevice:=rfcomm0}
sysctl -w net.ipv4.ip_forward=1
sdptool add --channel=1 SP
rfcomm --encrypt watch "$rfdevice" 1 pppd '{}'
"${localIP}:${bluetoothIP}" local nodetach noauth proxyarp $dns

This is with a recent BlueZ 4.x rfcomm.  I'm using an old kernel, which
has terrible bugs that are hopefully resolved in newer kernels (if I
disconnect from the Palm end before the Linux end, rfcomm seg faults
[might be a user level bug there] and I need to reboot in order to be
able to reconnect again).
