Subject: [B.A.T.M.A.N.] TT inconsistency problem (again)
Date: Tue, 06 Dec 2011 10:46:27 +0100	[thread overview]
Message-ID: <4EDDE473.5020008@agblab.com> (raw)

Hi,

I'm evaluating the possibility to use batman in our next product 
(measurement equipment) and I'm facing problems in using batman.
I have five nodes installed around and I experience black-outs in 
connection among nodes. The resoult is I can't ping a certain node anymore.

Here is the output from 'batctl o' and the subsequent ping to a node 
which has good link quality (TQ):

[root@gtam00119 ~]# batctl o

And this is the output from 'batctl ll tt routes' from he node that is 
being pinged (see above):

This situation was triggered by the following procedure:
1) from node (last two octets) 'a2:f6' the 'a3:0e' node was pinged
2) in the middle a ssh connection from the node 'a2:f6' was made to the 
node 'a3:0e'.
3) so far so good
4) the node 'a3:0e' was rebooted by issuing the 'reboot' command in the 
console
5) after this the connection is lost and the above logs were produced

I'm using the version 2011.4.0 on all nodes:
[root@gtam00119 ~]# batctl -v
batctl 2011.4.0 [batman-adv: 2011.4.0]

Any help is highly appreciated. I might be doing something wrong, but 
seems a stability problem.

Marko
