Subject: [Bluez-users] Is briding necessary?
Date: Tue, 16 Mar 2004 17:52:30 +0200 [thread overview]
Message-ID: <405722BE.4040306@nokia.com> (raw)
Dear all,
We have a Linux application which captures IP packets from given network
interface. Our current configuration is such that we have a bridge (br0)
containing eth1 and bnep0 interfaces and its working wonderfully.
However we would like to have only bnep0 interface so that there would
not be need for eth1 device. We have tried to use this bnep0-only
approach, but it is not working properly. What we see is:
1) PAN connection itself is successfully established
2) bnep0 interface is up
3) we can ping from mobile phone (device connected with PAN to Linux),
but we don't get replies back to mobile phone. We see though that ping
packets flow through our software to both directions i.e. ping-replies
are written to bnep0 too.
4) the state 3) stays there until we ping/traceroute the mobile phone
from the machine where the bnep0 interface is. After ping/traceroute
command the reply-ping packets start to flow to mobile phone too.
This is rather odd behavior and because we are not expert of PAN nor
Bluez we are wondering what could reason for above behavior. With
"bridge solution" there is no need to poll back the mobile connected via
bnep0/br0 instead everything works just fine after the bluetooth
connection is established. Can the bnep0 interface be actually used
instead of eth# or br# interface at all?
