[B.A.T.M.A.N.] Basic question
by Carlo Beccia 11 Feb '08

11 Feb '08

Hi all, a basic question for you guys... How can I compile the stuff https://dev.open-mesh.net/svn/batman/trunk/batman-adv-kernelland/ into openwrt...I would like to try the layer 2 version on my fonera router.... I don't understand if I have to integrate it in a package inside the menuconfig or I can build everything off from the standard configuration... >From Makefile I understand that the module is not actually integrated into the firmware but it is compiled outside of the menuconfig and then insmod on the target... I need some hint to create a right build environment... Thank you in advance Ciao, Carlo. _________________________________________________________________ Scarica GRATIS le tue emoticon preferite! http://intrattenimento.it.msn.com/emoticon/

[B.A.T.M.A.N.] Problems with 0.3-beta rv963 and kmod-batgat
by Vinay Menon 01 Feb '08

Hi, I am testing out batman 0.3-beta rv963 with openwrt-trunk (r10219) .

[B.A.T.M.A.N.] IMPORTANT: batman-exp <rv972 goes crazy after 49 days uptime
by Axel Neumann 01 Feb '08

01 Feb '08

Hey, I found out that the batman-exp daemon goes crazy when its internal life-time variable overflows. This will happen after 49 days, 17 hours, 2 minutes, and 48 seconds (which corresponds to 2^32 milliseconds). Unfortunately, its behavior afterwards can be anything between hanging around and doing nothing and an endless loop of sending packets. The problem is fixed with revision 972. If you are running batman-exp I strongly suggest to update. ciao, axel

[B.A.T.M.A.N.] gateway class/batmand termination
by Freifunk Dresden 31 Jan '08

31 Jan '08

Hi, I have implemented a mechanism that checks for a working internet connection. Depending on this batmand is called either with options "-c -b -r2" or "-c -b -g 1024/1024". Most often when batmand is called with "-c -b -g 1024/1024" batmand terminates: batmand -c -b -g 1024/1024 WARNING: You are using BatMan-eXp 0.3-alpha (compatibility version 10) ! Connection terminated by remote host. I have to restart batmand, but all routes are removed and batman loses its data. I also have to check for the internet connection again and must hope that batmand does not terminate. Batmand does not terminate every time. Any ideas? Tested rev. 966 (batman-experimental) /Stephan

[B.A.T.M.A.N.] batman OpenWRT integration
by Marek Lindner 28 Jan '08

28 Jan '08

Hi, finally I finished updating all the batman OpenWRT packages. Additionally, you can find the tunnel kernel modul, the battools and batman advanced (layer 2) kernel module in OpenWRT now. You need the latest trunk to get these updates. We are already working on a backport to 07.09 kamikaze but I'm not sure that these files are included in the official SVN repository. Feel free to contact me if you have any thoughts / wishes / bugs on that. Greetings, Marek

[B.A.T.M.A.N.] Memory leak
by Freifunk Dresden 26 Jan '08

26 Jan '08

Hello, I have a problem where batman (rev871 and rev908) consumes more and more memory until the router has no memory. I have added the output of the "top" command and the command line arguments of my setup. (WRT 10-1).....wlan.......(wrt 10-2) =======tinc vpn=====(laptop debian 0-1) kernel 2.4.32 kernel 2.4.32 kernel 2.6 I have seen that one batman thread changes the PID where the other stay the same. Below you will find the "top" output for batmand when it was started and after about one hour. The batmand running on kernal 2.6 does not increment its memory needs. Perhaps there are some allocation of memory that is not freed because of the arguments of the batmand. There is no special traffic on those nodes, they just are connected. Any Ideas?

by Murphy 02 Jan '08

02 Jan '08

Hallo, habe Deine Mail-Addresse nirgends gefunden, habe Chaosradio gehört und da hattest Du gesagt, daß Du keine Fonera besitzt und deswegen Multi-Mode/adhoc damit nicht testen konntest . Ich habe von Fon zu Weihnachten drei Foneras geschenkt bekommen (!) - war so ne Sonderaktion. Würde Dir gerne eine davon abgeben - falls noch Interesse besteht setz Dich einfach mit mir in Verbindung. Grüße, Murphy
