[B.A.T.M.A.N.] batman doesn't see neigh on wired lan

20 Apr 2011


      Hi!
Here in Pisa we are experiencing a big problem!
Nodes doesn't see each other on cable!
below is some data from the 2 nodes
As you can see nodes receives each other BAT packets but don't see
each other as neighbor...
also batctl tr can confirm it...
what is happening?
