Hii, I have fixed my problem... The reason was the HNA announce...After writing 129.211.186.0If/24 in the HNA field, I could make a traceroute to my server... Thank you all for the advices... If anybody has some advices, comments or want to discuss, don't hesistate to contact me... greetings, J > -----Ursprüngliche Nachricht----- > Von: "John Harris" <JHarris(a)web.de> > Gesendet: 31.12.08 13:24:46 > An: dondavis(a)reglue.org > Betreff: Re: [B.A.T.M.A.N.] Some questions to BATMAN > Hii Don, > > my scenario look like as follows... > > router 1 <---------------------> router 2 <-----------------------> router 3 (connected to server..IP 129.211.186.46) > eth1:bat eth1:bat eth1:bat (11.1.1.2) (wired: 129.211.186.12) > > The IP Adress of my router 3 is 129.211.186.12 (dhcp-lan), router 3 is connected to my server with the server IP 129.211.186.46. > > I can ping the eth1:bat interface of the router among each other.

[B.A.T.M.A.N.] Some questions to BATMAN
by John Harris 29 Dec '08

29 Dec '08

Hiii, I have some question about BATMAN routing protocol... I would be appreciate if anybody could help me... 1) I will build a mesh network.. One of my router is connected to my server with the IP 129.211.186.12. I can't make a traceroute through my router to this server. If I try to make "traceroute 129.211.186.12" from an another router I get the message: "PING 129.211.186.12 (129.211.186.12): 56 data bytes ping: sendto: Network is unreachable " I can send ping requests from my server to the router and from the router to the server, but as I said, I can't make a traceroute to the server from an another router. My question is, how can I do this ? In OLSR it was not a problem to trace the server through the router. Should I change something in HNA messages ? 2) I read the HowTO from Freifunk Leipzig about the configuration of BATMAN, look here http://wiki.leipzig.freifunk.net/BATMAN. How is the configuration If I want to run BATMAN in Ubuntu Intrepid? How can I configure the IPTABLES ? greetings, John _______________________________________________________________________ Sensationsangebot verlängert: WEB.DE FreeDSL - Telefonanschluss + DSL für nur 16,37 Euro/mtl.!* http://dsl.web.de/?ac=OM.AD.AD008K15039B7069a

[B.A.T.M.A.N.] batman advanced 0.1 release
by Marek Lindner 28 Dec '08

28 Dec '08

Hi, today, after a 6 months stabilization and debugging phase we release the first milestone towards a stable version: batman advanced 0.1. As this implementation resides in the kernel land only we wanted to make sure its stability before releasing it to the public. This batman implemention is marked with the label "advanced" to outline the fact that it operates on layer 2 (mac layer) as opposed to batman which operates on layer 3. To gain optimal performance it resides in the kernel as a module and can be enabled/disabled/configured via the /proc/net/batman-adv/ interface. Unfortunately, we can not offer precompiled packages for your kernel as the module sources need to be linked against your very own kernel headers. If you are using debian you will find packages that you can install via apt-get. OpenWRT also has the package included. If you intend to use the module on your own system, simply download the sources, build and load the module. You can find the sources here: http://downloads.open-mesh.net/batman/stable/sources/ Special thanks to Sven Eckelmann and Scott Raynel who spent a considerable amount of time testing, debugging and patching the sources. We included all their patches which allow us to release today. The biggest changes since the beta release are: - support latest kernel version (2.6.20 - 2.6.28) - LOTS of cleanup: locking, stack usage, memory leaks - Change Ethertype from 0x0842 to 0x4305 unregistered at IEEE, if you want to sponsor an official Ethertype ($2500) please contact us We welcome any feedback/patches/ideas, The B.A.T.M.A.N. developer team

[B.A.T.M.A.N.] [PATCH] Split SOURCE_VERSION in RELEASE- AND EXTRA_VERSION
by Sven Eckelmann 28 Dec '08

28 Dec '08

RELEASE_VERSION and EXTRA_VERSION can be concatenate to a single SOURCE_VERSION string. This makes it possible to detect unstable versions during compile time instead of removing the unstable warning in a seperate commit (or forget this change). Before releasing the a new stable version the release manager must set EXTRA_VERSION to "", check INSTALL, THANKS and README and then create the tag in the repository. Afterwards the development branch should change the RELEASE_VERSION to the upcoming version number and the EXTRA_VERSION to a string which informs the user that it is "unstable" and in development. This could be for example "-dev", "-pre-alpha", "-beta" or "-rc1".

[B.A.T.M.A.N.] [PATCH] batman-adv-kernelland: Fix memory corruption bug
by Scott Raynel 12 Dec '08

12 Dec '08

Hi there, I've been spending some time tracking down a bug that's been causing memory corruption followed by random kernel panics. Thanks to the kernel's slab memory debugger I tracked it down to a kfree in send.c that was freeing a block of memory that had been written to past the end of its allocation. Turned out to be a simple typo, which I've fixed in the following patch. When resizing the packet_buff struct in batman_if, the new length was being updated but the old length was being used for the kmalloc(), causing something later to think it had more memory allocated to write to, hence writing past the end of the allocation.
