[Bluez-users] How to setup a pptp-connection via the dund-service ?

Hello,
Does someone has successfully tried to set up a pptp server via dund 
communicating over Bluetooth?
My first attempt does not work as expected...
How does interact the dund with the pptpd and the pppd ?

It would be helpful to see some commandline examples.
 
Thanks in advance


Mit freundlichen Grüßen / kind regards

Andreas Knuth

[Bluez-users] Bluetooth instability problem

[Jens Hottenroth]

Hi to anyone!

I don't know if i'm at the right spot here, but i'll ask here first. I
have the following problem:

I've 3 "PCs" (one is an embedded linux based broadband handheld tester,
afterwards refered to as bbt), all running linux with Kernels from 2.24
(bbt) to 2.26 (PCs), and identical bluetooth usb-sticks (D-Link BT120).

Here's what i've done / what i know:

Downloaded the latest bluez-libs and bluez-utils, compiled and
installed. Ran configure / make for a new kernel with only that
functions needed, installed it to the bbt.

Running some tests with l2ping brought the following results. I can ping
the bbt, sometimes i get no response messages (max. 5 after another,
most times 4 in a row). This test runs for about 30 minutes, then i
canceled it. The bigger I define paketsize (defaults 44 Bytes) the
faster / more often come those no response messages and, here it comes!,
when more than 250 Bytes are specified, the connection hangs! Aprox. 2
minutes. The bigger the paketsize the faster it hangs.
After it once hung, only a total reset of the bbt gets it running again.

Between those 2 PCs, I only had problems with rfcomm and dun, pan worked
just fine. After i updated the Systems (it's SuSe linux 9.1 and 9.3, i
forgot to say that) those problems where gone.

The biggest Problem is, that i can't path or upgrade the kernel in the bbt.

Does anyone have any suggestions?

what kernel versions are you using. You mentioned onyl the bluez-utils
versions. Please specify the exact commands you are using for testing
and include the output of "hcidump -X -V".

so far I don't know of anybody who ever tried this. Maybe we need to
extend dund with some pptpd capabilities, but I never used pptpd and so
I have no experiences with it.

I've done it indirectly with doing an unencrypted PPP connection
over dund and over this tcp/ip layer I connected to the pptp
service.

With the Palm PDA I had to do it like this anyway, because it only
supports PPTP over IP and I guess other clients have the same
behaviour.
