[B.A.T.M.A.N.] A tutorial for BATMAN (on openwrt)
by nick farrow 12 Jun '09

12 Jun '09

Hi, I would be really greatfull if someone could point me to some basic instructions to get me up and running. I have installed batman and olsr on my trusty linksys wrt54g but have no idea how or what I need to do from here (other than put the wifi into adhoc mode). I have found some basic instructions but dont really understand them and am having trouble getting anything that really describes the whats and whys. Thanks very much nick _________________________________________________________________ Share your photos with Windows Live Photos – Free. http://clk.atdmt.com/UKM/go/134665338/direct/01/

[B.A.T.M.A.N.] ath9k and batman-adv
by austinxxh-ath9k＠yahoo.com 06 Jun '09

06 Jun '09

I'm trying to use batman-adv with ath9k/openwrt. two boards(each board has one ath9k card and one ath5k card), ath9k on both boards are configured at the same channel(5), then I did : #echo wlan1 > /proc/net/batman-adv/interfaces on each of the board, however #cat /proc/net/batman-adv/originators showed up nothing. Note: I have wlan0 with ath5k for AP, on different channels. I also have eth0 with local IP address but I did not add it to batman-adv. I then tried to configure bat0 with IP address and then ping, of course it did not work. anything else that I am missing here? anyone had success with ath9k/batman-adv? thanks! xxiao

[B.A.T.M.A.N.] Kernel crashes with batgat installed
by Nathan Wharton 03 Jun '09

03 Jun '09

I am using batman 1256 on a very recent openwrt (linux version 2.6.28.10) as well as a bit older one (linux version 2.6.26.8). With batgat installed, I have problems with the kernel crashing when turning the gateway on and off. I start batman with -r 2. If I detect an uplink, I issue -c -g 11000. If I lose the link, I issue -c -r 2. It is this final -c -r 2 that causes the kernel to either crash with a bad page on the next process that is created, have a null pointer error, or have a recursion error. If I run batman without batgat, I don't get any crashes. Everything works fine otherwise. Except one thing that just came to mind, I had to remove -DDEBUG_MALLOC -DMEMORY_USAGE because batman wouldn't do anything without crashing because of magic number problems. Could this be because I am on Big Endian hardware? Could anyone else see if they have the same problem? All you have to do is have batman running with batgat installed, start issuing batmand -c -g 11000 ; batmand -c -r 2 multiple times and see if their system stays stable. Thanks.

[B.A.T.M.A.N.] Multiradio Batman
by Kartik Muralidharan 29 May '09

In this case, you might want to add a > cost to hop over the same wireless interface. >Ok, good idea. I quickly made a patch: >http://www.open-mesh.net/changeset/1276 >Feel free to test it. :-) >Regards, >Marek But how would batman choose the next hop if at every node there are two interfaces available. The ideal ofcourse would be 11a->11b->11a->11b->11a on each hop. Regards Kartik

>Right, that is still on open point on my ToDo. I'd like to automate that if >possible but did not have a good idea how to do that. >Kartik: Any idea how roofnet is doing it ? Config ? @Marek Roofnet does not consider multiple interfaces. It was meant to work over only a single radio. The work around is to consider WCETT metric rather than ETT that is currently used in roofnet.

[B.A.T.M.A.N.] Make batman-adv a multicast-aware layer 2 switch
by Linus Lüssing 27 May '09

27 May '09

Yesterday, we (Marek, Julian, Linus) had some thoughts about the advantages of having a multicast-aware BATMAN-Adv. Also some first ideas about the actual implementation in BATMAN-Adv, which is not a trivial task, have been discussed. The results so far and the irc-log can be found in our wiki from the Lübeck-Freifunk (http://luebeck.freifunk.net) in the section Network->BATMAN-Adv-Multicast-Development. We definetly want to push this feature further as it is especially very useful in Mesh-networks and would like to hear from any other ideas of how to implement this in the most efficient way and if there are any concerns about the ideas for implementation yet. Also a trac-enhancement-ticket can be found here: http://www.open-mesh.net/ticket/128 Sincerely, Julian, Linus - MetaMeute
