I am new to Linux and Bluez so maybe someone could give me a hand here? Thanx
ahead!
I am using a 2.4.2 kernel (SuSE 8.2) and the bridge within it to tie a
bluetooth PAN and my Laptop together under one IP address which must come
from a DHCP server as I am using the constellation in various networks.
The bridge is activated like this:
brctl addbr pan0
brctl addif pan0 eth0
brctl setfd pan0 0
brctl stp pan0 disable
(got those settings from a bluetooth howto, activated by a init.d/rc5 script -
works fine)
ifconfig eth0 0.0.0.0 then disables the IP on my lan card for the bridge to
work, set by the ifcfg-eth0 init.d file.
the ifctrl-pan0 calls the DHCP server for an IP adress and this is assigned -
works well.
brctl addif pan0 bnep0 gets called from the bluetooth startup (hotplug)
With the bluetooth pan added to the bridge heres the trouble I have:
While before pings to the local machine work ok and I get constant periodic
reponses, after the bnep0 interface becomes part of the bridge, ping stops
about every 5 instances, no longer displays the ping'd machine's name and
goes down with response frequency (from normally one a second to one response
every 10 or so seconds). While the response frequency remains low, after 8-10
no-name resolution pings, the machine name comes back with each ping. and so
on....
Pings directly to the IP address continue to work fine, also pings from
another machine in the network to both my local linux laptop and the
bluetooth attached PDA. Also DHCP is working fine for the PDA.
Any ideas? Thanks ahead for your help!
Theo

This kernel is quite old. You really should upgrade the kernel...

I had similar problems with a very similar setup.
The problem is that when the bnep0 interface enters the bridge, the bridge's
"mac address" changes. You can see that happening doing a "ifconfig pan0" before
the bnep0 joining the bridge and after, to see the hardware address of the pan0
interface.
I tried to solve this by issuing "arping's" so that other machines on the
network would be warned about the new hardware address, but unfortunately never
got this to work properly... :(
It has been quite a while since i've tried this, though. So maybe in recent
versions the bridging layer doesn't change the hardware address anymore?
If you have better luck than me, please let me know.

I never put the eth0 into the bridge ;) You can use IP forwarding and
NAT between eth0 und pan0.

Marcel,
thanks, I tried this but couldnt get it to work at least with SuSEfirewall2,
activating NAT between the internal:pan0 (bridge) and external:eth0. ANy
other ways?
What I am trying to get to: as I use my linux-laptop online (DHCP on eth0 in
different networks) and offline (with th PDA/BT connection with apache etc.
running on the laptop) my plan was to have a default configuration which at
boot is overridden after DHCP on eth0 (or the bridge) has provided the laptop
with its network IP, gateway and so on.
As I said, new to all this stuff....
Tx again

Just one more thing i forgot to mention: you can try and send a similar report
to the bridging mailing list to see if there is some solution on the bridge side.
The mailing list for bridging is at:
http://www.math.leidenuniv.nl/mailman/listinfo/bridge
I hope this helps,
