[B.A.T.M.A.N.] Layer 2.5
by Breno Jacinto 04 Feb '09

04 Feb '09

Hello, I read some posts on the web about B.A.T.M.A.N being (or becoming) a layer 2.5 protocol, which would make it operate below IP. But, at the website and some papers I read this is not mentioned, and the impression is that it is a regular layer 3 protocol. Can anyone please clarify, and if possible, point to some reference that may confirm that batman is or is not operating at layer 2.5? I'm writing a paper on mesh protocols and I need to know which layer batman really operates in order to cite it correctly. best regards, -- -- :: Breno Jacinto :: :: breno - at - gprt.ufpe.br :: :: FingerPrint :: 2F15 8A61 F566 E442 8581 E3C0 EFF4 E202 74B7 7484 :: Persistir no difícil é a única maneira de torná-lo fácil algum dia. ::

Hi, I've make a test today with Batman and La Fonera2. I've a problem with the 169.254.0.0/16 routing. In fact, when i launch batman, the 169.254.0.0/16 route with gate0 dev don't add correctly. With this, i can't have reply on my request. If i add manually the route with "ip route add table 254 to 169.254.0.0/16 dev gate0" this work. How can i debug this problem.

[B.A.T.M.A.N.] Help in batman advanced configuration
by Gargi Purohit 27 Jan '09

27 Jan '09

Hi I am trying to bring up open mesh with batman advanced. My network configuration is as follows: _____DSL cable_____Linksys Router____Cisco PIX______Switch______ open mesh 1 ---------- open mesh 2 -------- client laptop 192.168.50.1 | _______ my PC |_______ |_______ |_______ My IPs get automatically assigned by the PIX (In the subnet 192.168.50.0) OPEN MESH 1 - configuration =========================== 1. I stop the routing daemons running on them. It has eth0, ath0, ath1 and ath2 interfaces where ath0 is in adhoc mode and ath1 and ath2 are in master mode I create a bridge between all these interfaces (br0 - eth0, ath0, ath1, ath2) and i run udhcpc with br0 as an argument so that my bridge gets an IP from the network All other interfaces are given an IP of 0.0.0.0 My bridge gets an IP (192.168.50.5) I have batman_core module and i update the /proc/net/batman-adv/interfaces with br0 interface echo br0 > /proc/net/batman-adv/interfaces OPENMESH 2 - configuration ========================== 1. I stop the routing daemons. It has ath0, ath1, ath2 interfaces. I again bridge these interfaces (br0 - ath0, ath1, ath2 I try getting an IP for this node usign the same method of running udhcpc but i am unable to So I dont have an IP - but i dont worry about it now. I have batman_core module and i update the /proc/net/batman-adv/interfaces with br0 interface echo br0 > /proc/net/batman-adv/interfaces OBSERVATION =========== Now when i check connectivity using battool i can ping between openmesh 2 and openmesh 1 using battool bp My originators file indicate the mac of the other mesh node E.g. on openmesh2 root@open-mesh:/proc/net/batman-adv# cat originators Originator (#/255) Nexthop [outgoingIF]: Potential nexthops .. . [B.A.T.M.A.N.

[B.A.T.M.A.N.] nat & aggregation
by Marek Lindner 26 Jan '09

26 Jan '09

Hi, today I submitted the first patches into the 0.3.2 branch. Some of these patches change the behaviour of batman: - Aggregation is now enabled per default. We tested since a while now and believe it is ready for a broader test. If you experience problems with your routing you can disable the aggregation using the "--disable-aggregation" option and verify whether it is related to the aggregation or not. Please inform us about your experience. - We noticed that quite some newly interested people have difficulties dealing with batman since it requires NAT on the internet tunnel. Therefore the NAT on the gate0 device will be configured by batman automatically. The iptables binary is called to modify the outgoing NAT rules. This should make it easier to get started with batman. Regards, Marek

[B.A.T.M.A.N.] batmand-howto conversation
by Sven Eckelmann 25 Jan '09

25 Jan '09

Hi, I could not find any type of "source" (aka batmand-howto.odt in this case) of the batmand-howto written by Wesley Tsai and it seems to be partially outdated. Because of that I decided to do a conversation of the PDF to LaTeX so it can be changed more easily. It is quite rough at the moment, but I hope that their is some kind of interest in it. Current sources can be found at http://gitorious.org/projects/batmand-howto and Simon and Marek have write access to mainline. Best regards, Sven

[B.A.T.M.A.N.] batman 0.3.1 released
by Marek Lindner 25 Jan '09

25 Jan '09

Hi, the B.A.T.M.A.N. team is pleased to announce the availability of batman 0.3.1 a bugfix and maintenance release. As usual, we provide precompiled packages: http://downloads.open-mesh.net/batman/stable/binaries/ as well as signed source tarballs: http://downloads.open-mesh.net/batman/stable/sources/ As you may have noticed we slighty modified the folder structure to seperate binaries and sources better. Also, we will keep providing older source tarballs to support the various distributions better. In addition, we added a release "bundle" folder which contains related source packages: http://downloads.open-mesh.net/batman/releases/ Many people outside the B.A.T.M.A.N. team contributed to make this release possible. Thanks to everyone that helped us. Special thanks goes to Antonio and the open-mesh.com crew. They provided us with bug reports, test beds and ideas to improve the overall batman experience. Also, we wish to thank Sven Eckelmann for his endless stream of patches and thoughtful hints. During the past months the code received improvements all over the place. Nearly all functions were touched. The packet aggregation was debugged and improved. Areas with a high density of nodes suffered from bogus routing information which was fixed. BSD compability was committed. Now, on a changing route batman adds new routes to the kernel routing table before the old routes are deleted to avoid race conditions. The batgat kernel module received many fixes that improve stability. The makefile reduced the verbosity of its output to allow easy distinctions between warnings and commands. The full changelog can be retrieved here: http://open-mesh.net/log/trunk/batman?rev=1201 Happy routing, Marek

Hello, I apologize for the extremely naïve question. I have a couple of embedded devices (x86) running the latest version of OpenWRT. I would like to know if I could compile and run batman on these nodes and if so how. Thanks in advance. Kartik

[B.A.T.M.A.N.] possible on any device with batman?
by M. Peterson 22 Jan '09

22 Jan '09

Worried about the local copyright traffic cops slowing your internet connection down? Concerned that your latest BitTorrent upload will get you busted? The latest device from Leyio has introduced<http://www.techradar.com/news/computing-components/storage/leyio-uwb-key-sh…>their Personal Sharing Device (PSD) that lets you trade files with literally a flick of the wrist. Leyio's <http://www.leyio.com/> irritating website gives scant details on the product, but there's enough information around to get a better understanding of the device. It uses Ultra Wide Band (UWB) wireless technology to transfer files between PSD users, and for us mere mortals with only lowly USB sticks, it has support for those as well. There doesn't appear to be any DRM restrictions, and Leyio's website appears to indicate the just about any file can be shared. So let's say this product takes off and many people own a PSD. If you wish to share files with someone, just flick the device right at the person you wish to share with, and that's it. Security concerns are addressed with fingerprint technology. File-sharing doesn't get much easier than that. Pricing hasn't been released yet. It's scheduled to be available in April of 2009, and Leyio's blog is scheduled to be launched in February. http://www.slyck.com/story1825_FileSharing_with_a_Flick_of_the_Wrist http://74.125.43.100/translate_c?hl=de&sl=de&tl=en&u=http://www.gulli.com/n… http://www.gulli.com/news/leyio-filesharing-offline-bald-2009-01-22/ Filesharing Leyio offline reality soon? Eine interessante Entwicklung aus dem Hause Leyio, welche in naher Zukunft auf den Markt gelangt, könnte die Filesharer-Szene aufmischen und zugleich den schlimmsten Albtraum der Industrie wahr werden lassen. An interesting development from the house Leyio, in the near future on the market, the scene Fileshare it up at the same time, the worst nightmare of the industry true. Filesharing ohne PC, ohne P2P-Client und das höchste der Gefühle: Ohne der immer währenden Furcht, die Piratenjäger der Content-Industrie auf sich aufmerksam zu machen. Filesharing without a PC without P2P client, and the highest of emotions without fear of ever-lasting, the pirate hunter of the content industry to draw attention to itself. All dies könnte womöglich bald so real sein, wie noch nie zuvor.All this could possibly be real soon, as never before. Genauer gesagt ab April 2009 - also in rund 3 Monaten. More precisely, from April 2009 - so in about 3 months. Aber tragen wir die bislang sehr spärlichen Informationen erst einmal zusammen. But so far we have very scanty information only once. Leyio hat ein kleines und handliches Gerät entwickelt, welches an und für sich keine großartige Vielfalt bietet, da es für sich allein relativ wenig kann. Leyio has a small and handy<http://74.125.43.100/translate_c?hl=de&sl=de&tl=en&u=http://www.gulli.com/n…>device, which in and of itself does not offer great diversity, because it alone can be relatively low. Getauft wurde es auf den Namen "Personal Sharing Device", was einige sicherlich zum Aufhorchen bringt. It was baptized in the name of "Personal Sharing Device", which some certainly Aufhorchen brings. Neben einem Touchscreen mit Fingerabdruckscanner verfügt das Gerät über einen internen Speicher, welcher etwa 16 Gigabyte groß ist.In addition to a touch screen with fingerprint scanner<http://74.125.43.100/translate_c?hl=de&sl=de&tl=en&u=http://www.gulli.com/n…>, the device has an internal memory, which is about 16 gigabytes in size. Des Weiteren lassen sich USB-Sticks an das Gerät anschließen, ob weitere Anschlüsse unterstützt werden, ist bislang unklar. In addition to USB<http://74.125.43.100/translate_c?hl=de&sl=de&tl=en&u=http://www.gulli.com/n…>sticks to the device, whether additional connections are supported, is so far unclear. Das Herzstück des Geräts bildet jedoch die "Ultra-Wideband" Funktechnologie, welche eine Reichweite von etwa zehn Metern bietet, auf welchen mit 10 Megabyte pro Sekunde übertragen wird. The heart of the device, however, the "Ultra-Wideband radio technology, which has a range of about ten meters offers, what with 10 megabytes per second is transmitted. Mit diesem Gerät könnte Filesharing<http://74.125.43.100/translate_c?hl=de&sl=de&tl=en&u=http://www.gulli.com/f…>dorthin wandern, wo die Content-Industrie wohl nie mehr dagegen vorgehen kann. With this device could Filesharing<http://74.125.43.100/translate_c?hl=de&sl=de&tl=en&u=http://www.gulli.com/f…>migrate there, where the content industry on the other hand, probably never can proceed. In öffentliche Parks, private Wohnzimmer, Schulen und sonstige Plätze. In public parks, private living rooms, schools and other places. Der User kopiert einfach zu Hause seine Daten auf den internen Speicher des Geräts, oder alternativ auf einen (oder mehrere) mitgeführte USB-Sticks. The user simply copied his data at home on the internal memory of the device, or alternatively to one (or several) on board USB sticks. Trifft man einen Freund, welcher unbedingt das Musikstück X haben möchte, so genügt eine kurze Auswahl auf dem kleinen Gerät, um den Track mithilfe der Funktechnologie zu senden - vorausgesetzt der Freund verfügt ebenfalls über ein Gerät, welches diese Technik unterstützt. If you have a friend that is necessarily the music piece X wants, suffice it to a short selection of the small device to the track using the wireless technology to send - if the friend also has a device that supports this technique. Falls nicht lässt sich an das Personal Sharing Device einfach ein USB-Stick anschließen, auf welchen die Daten dann kopiert werden. If not, is evident from the staff sharing device simply connect the USB stick on which the data is then copied. Man kann sich denken, wohin dies führen wird. One can imagine where this will lead. "Personal Sharing Device Partys". "Personal Sharing Device parties." Die ganze Clique bestückt ihre Geräte mit allen medialen Inhalten und trifft sich zu einem gemütlichen Abend im Kino. The whole gang equipped with all of their media content and meet for a leisurely evening at the cinema. Beim Kaffee vor dem Film zücken alle ihre Geräte und der fleißige Datenaustausch untereinander geht los - einzig begrenzt durch die Reichweite des Funksignals. At the coffee before the film zücken all their equipment and the hard data with each other is going on - only limited by the range of the radio signal. Wer auf Nummer sicher gehen will, nutzt keinen USB-Stick sondern nur den integrierten Speicher des Personal Sharing Device (PSD). Who on the safe side, do not use a USB stick but the memory of the integrated staff Sharing Device (PSD). Droht "Gefahr", so lässt sich das Gerät sperren, und ist nur mithilfe des Fingerabdrucks des Besitzers wieder nutzbar zu machen. Threaten "danger", it can disable the device, and is only using the fingerprint of the owner to use again. Wie teuer das Gerät wird, ist bislang nicht bekannt. How much the unit is not yet known. Eines dafür jedoch umso mehr: Die Industrie hat Filesharing langsam aber sicher dorthin gebracht, wo sie es nicht mehr bekämpfen können. One, however, even more so: The industry has slowly but surely Filesharing there, where it can no longer fight. Mit dem PSD von Leyio wird der Austausch so leicht, wie lange nicht mehr. The PSD Leyio of the exchange so easily, like a long time.
