Hi,

I saw strange batman logs while testing a batman-adv mesh. Batman-adv
module was continuously generating the same logs including a " Creating
new originator: b0:c6:9b:80:01:43". But b0:c6:9b:80:01:43 never appears in
the output of 'batctl o': admin@HND-Mesh:~# batctl o
[B.A.T.M.A.N. adv 2012.0.0, MainIF/MAC: wlan0/b0:c6:9b:80:01:5b (bat0)]
  Originator      last-seen (#/255)           Nexthop

(227) b0:c6:9b:80:01:5c (244) b0:c6:9b:80:01:5f (255)

Now I can nerver reach b0:c6:9b:80:01:43. Anyone tell me why this happens?

according to your logs OGMs from b0:c6:9b:80:01:43 are received via nodes that 
are not in your routing table either:
 * b0:c6:9b:80:01:57
 * b0:c6:9b:80:01:6c

Therefore you see the warning: Drop packet: OGM via unknown neighbor!
Batman-adv can't create a route to a an originator without having a next hop. 

Do all nodes in your network run the same batman-adv version (2012.0.0) ?
