Subject: [B.A.T.M.A.N.] Can't create new originator
Date: Sat, 26 May 2012 17:20:28 +0800 [thread overview]
Message-ID: <4fc0a063.2a04440a.04d9.ffffbef5@mx.google.com> (raw)
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':

Now I can nerver reach b0:c6:9b:80:01:43. Anyone tell me why this happens?
And, what does "Drop packet: packet within seqno protection time" mean? What is the "seqno protection time"?
Any help will be appreciated and thanks in advance.
