<p>Whats about making a default based on ipv6? This would make it easy to prevent address collisions by the starting script.</p>

Thanks, that was a useful description. I think I'll go back to my<br>
original idea with is and make the default setup have sensible defaults<br>
in olsrd.conf then use these settings for the adhoc setup:<br>
<br>
SSID: <a href="http://olsr.org" target="_blank">olsr.org</a><br>
BSSID: cc:cc:cc:cc:cc:cc<br>
channel: 7<br>
ip address: 172.29.x.x with x being the last digits of the MAC<br>
netmask 255.255.0.0<br>
Ip4Broadcast 255.255.255.255<br>
LinkQualityFishEye 1<br>
LinkQualityAlgorithm "etx_ff"<br>
<br>
This will let people easily start a mesh with whoever is nearby, but<br>
make it harder for them to inadvertently connect to a mesh and mess it<br>
up. Do the above settings make sense? I think "Ip4Broadcast<br>
255.255.255.255" and the use of InterfaceDefaults are the only changes<br>
from the previous olsrd.conf that was included, besides text formatting.<br>
