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.

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) ?

Marek

Hi, Marek.
Every nodes run the same version of batman.
I attatch the topology of my mesh network.When b0:c6:9b:80:01:53 is on (working),b0:c6:9b:80:01:5f can reach b0:c6:9b:80:01:43,and the hole network is ok.b0:c6:9b:80:01:5b's nexthop to b0:c6:9b:80:01:43 is b0:c6:9b:80:01:57 or b0:c6:9b:80:01:6c, and sometimes b0:c6:9b:80:01:53.
But when I shut b0:c6:9b:80:01:53 down,it seems b0:c6:9b:80:01:5b can't reach b0:c6:9b:80:01:57 neither b0:c6:9b:80:01:6c,as I mentioned in my firt email.
When I turn b0:c6:9b:80:01:53 on again,the hole mesh is ok again.
Marek,can you tell me what the problem probably is.

The mesh connections are too weak without b0:c6:9b:80:01:53 ?
I don't really have an idea what your setup is and how it looks like to draw
any meaningful conclusion.
