I just looked on every node in the network and can't find any nodes with 
these macs.
ifconfig | grep -i "4c:c8\|05:01\|48:c8" ; arp  | grep -i 
"4c:c8\|05:01\|48:c8"

ATM there are only the mesh-nodes, one internet-router and a camera 
connected. The router is in the middle and the camera on one end. (3-4 
hops from the internet-router)

Well, i can't reach the camera right now - i have to reset the node maybe...

When everything is working i get a HD-picture from the camera every 
second. So the connection is good (when it's working...)

I notices another mac 04:11:81:b9:42:c8 and looked in the log of node bat54:
root at fon-53:~# batctl l | grep "42:c8"
[     87390] Creating new global tt entry: 00:02:81:b9:42:c8 (via

[     87390] Deleting global tt entry 00:02:81:b9:42:c8 (via 
5e:e6:fc:ae:55:a8): originator time out

the via is from bat51 - unfortunately i dont have loggin on that node - 
i'll install a different image later

funny thing is bat49 which is directly connected to bat51...

...does hear different broadcasts:

These "via"-mac points back to bat53 but in the log of bat53 i only see 
that they are comming "via" bat51.

There is nothing connected to bat51 or bat53 - both are wifi-only and 
nobody can connect to them atm (except the mesh)

Why does it create a global tt entry and delete it a second later?
