Hey guys,<br>
<br>
I'm really desperate and maybe you can help me with my strange (and I<br>
hope little) problem.:<br>
<br>
-> I have a nokia N810 running (192.168.2.11) and a Notebook<br> (192.168.2.10) in a ad-hoc network</blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
-> as soon as I start olsrd (i need to run version 0.5.6-r7) the<br>
notebook and the nokia device start sending hello messages and<br>
adapting their routes as expected<br></blockquote><div>who/what forces you to do so? </div><div><br></div><div>(any fix we might do, or already did to you problem will require u too use a never version,..)</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
-> I have still no problems pinging the nokia from the notebook... but,<br>
I can't ping the notebook from the nokia anymore... except with a<br>
broadcast ping. Can anybody tell me what the reason for that problem<br>
is?</blockquote><div>no, u have to find out yourself, as this is definetly nothing that usually happens,..</div><div>or which has a single/simple reason,..</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
The hello message exchange is still working fine... I guess that<br>
explains why a broadcast ping is possible.<br></blockquote><div>hmm can u run tcpdump on your nokia?</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<br>
These are the computed routes on my notebook:<br></blockquote><div>they look good,.. </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

The problem seems to be the first route of the nokia. As soon as I<br>
remove it the ping works again. But why? There is no difference to the<br>
Notebook routes and the notebook is still able to ping the nokia<br>
device.<br></blockquote><div>the first route is the only route that olsrd creates, it might change the source ip the nokia chooses, or other things,..</div><div><br></div><div>do you have smae problem if u do this instead of running olsrd</div>
<div><br></div><div>(should fail like olsrd's route)</div><div>ip route add 192.168.2.10 dev wlan0 metric 2</div><div><br></div><div>or alternatively (might work)</div><div><div>ip route add 192.168.2.10 via 192.168.2.10 dev wlan0 metric 2</div>
<div><br></div></div><div>if possible use tcpdump (it might be enough to use it on the notebook if not possible on nokia) to find out what different icmp/arp packets the nokia sends (if it still sends any) as soon as this route is there/gone</div>
