I've downloaded and installed the 0.3 current for fonera-kamikaze platform and it seems work fine in a robin mesh cloud... but I've a problem which I don't well undestand. When batmand starts it ask me for a /dev/batman (a modul kernel) which would improve performance. I never read before about /dev/batman, so, anyone can suggest where I can find more documentation?
Well, we are currently sedulously working on improvements on the performance of batman in the areas of cpu consumption and path detection. The kernel module is an approach by Andreas and Marek to optimized cpu-load. You can safely ignore this message because having the kernel module installed is not mandatory. The idea is that if batman finds the kernel module it can be used by the userspace batmand. IMHO (as in most open-source projects) the documentation is always one step behind the latest development approaches. Thats why its in the development and not in the stable stable folder.
I believe that the originator messages compatibility number was been incremented in o.3 because a node running 0.2 doesn't see OGMs coming from batman o.3 nodes... is this correct?
Actually the compatibility number has not been increased with batmand-0.3_alpa but the udp port number used by batman has changed. Simon has managed to convience IANA to reserve a dedicated port for batman which is now 4305 (see: http://www.iana.org/assignments/port-numbers )
( Just in case you downloaded batmand-exp_0.3, there the compatibility number has been increased because it contains some experimental routing concepts which are considered incompatible with the previous algorithm. Launch $batmand -v to get some feedback about the running version and compatibility number )
ciao, axel
Thanks
