Hi,
I'm using experimental batmand Rev 756. After a while the batmand is crashing.
with "Segmentation fault". the crashing batmand is running on i386 (debian 2.6.22.1).
All routers are running the same batmand version. I have not checked if also the
batmand crashs on the routers.
syslog: batmand[6733]: Error - got packet from unknown client: 10.12.10.17 (virtual ip 169.254.1.1)

Just to be sure, Where does it show Rev 756 ? Because this reveision has never
been committed for batmand-exp. Do you mean rv752 ? Have you experienced this
with previous revisions?

can you check that? To be honest, I am usually not testing it a lot on i386.
I'll do so now. But on the mipsel devices which Iam mostly using for testing
it runs since weeks without problems.

can you send me that batman-crash file, and even better also a core dump? (if
its to large send it private).
thanks,
