I have 8 wrt54gl's running openwrt + batman. I set all to auto channel + ad-hoc. I'm trying this startup script. ifconfig eth0.0 103.0.0.* netmask 255.0.0.0 broadcast 103.255.255.255 & ifconfig wl0 103.0.0.* netmask 255.0.0.0 broadcast 103.255.255.255 & batmand eth0.0 eth0.1 wl0 & iptables -t filter -I INPUT 2 -p udp --dport 1966 --sport 1966 -j ACCEPT & iptables -t filter -I OUTPUT 2 -p udp --dport 1966 --sport 1966 -j ACCEPT & I did a kismet scan and only 4 are showing up. All 8 have wlan lights blinking in sync. Should I manually set the channel? Do the essids matter? Should the lan ip be the same as the ip I give the batman device? do I need to use wan ips?

I guess I should start with: 1. How should I set up the preferred gateway? 2. what do I need to do besides batmand interface? 3. Thoughts on how to setup a second nic on a computer in order to allow it to work as a visualization server? On Sun, 2008-03-09 at 22:07 +0100, elektra wrote: > 1.

I was looking at some routing some of the udp packages batman needs. well iptables -F killed the router (that would make sense, flushing the iptables on a router)... I'll try iptables -t filter -I INPUT 2 -p udp --dport 1966 --sport 1966 -j ACCEPT; iptables -t filter -I OUTPUT 2 -p udp --dport 1966 --sport 1966 -j ACCEPT; iptables -t filter -I ipfilter 5 -s 103.0.0.0/8 -d 103.0.0.0/8 -j ACCEPT; > 3. The hints that you are giving are very sparse - which version are you > using, your ip-settings etc. Sorry. I didn't want to type a a lot of info without knowing what would be useful. It's Batman 0.2 compatibility version 3. I'm very unsure about a few things. when I type ifconfig on the wrt54gl I have following devices br-lan eth0 eth0.0 eth0.1 lo wl0 the web interface on x-wrt offers me br-lan and eth0.1 by default and eth0.0 once I bring it up on the cli. so I use ssh and start batmand br-lan eth0.0 eth0.1 at one point I had vlan0 but it disappeared without my (consciously) disabling it. I chose eth0.0 as the primary interface and routing class 1. ifconfig eth0.0 103.0.0.(number of router) netmask 255.0.0.0 broadcast 103.255.255.255 I'll try ifconfig br-lan 103.0.0.* and use it as the primary interface.

I've been trying to get batman running on a a few wrt54gl's with openwrt kamikaze + x=wrt. Has anyone on the list had success with this? I am unsure about the wireless mode. I thought ad-hoc, but I've also tried client and ap mode. I tried batmand br-lan batmand eth0:1 I've tried running several all on channel 1. And they reported there were no batman nodes in range. What have I left out?

[B.A.T.M.A.N.] B.A.T.M.A.N. RFC Draft
by Marek Lindner 07 Mar '08

07 Mar '08

Hi, last months we have worked on a RFC draft to document the B.A.T.M.A.N. protocol. Finally, the day has come to publish the results. You can find the draft in our document section (https://www.open-mesh.net/batman/doc). Simon is going to send the draft to the RFC editors to start making it a real standard. If anyone has time and/or experience to support that process - you are welcome to join the effort. Regards, Marek

Re: [B.A.T.M.A.N.] Rev 972: batmand -c -d n hangs sometimes
by Freifunk Dresden 25 Feb '08

Hi Axel, when I use rv980 and call "kill -STOP $(pidof tincd)" then batman works for a while (1-2 minutes) and exists with the following error: [ 411413] Error - can't send udp packet: Resource temporarily unavailable. Connection terminated by remote host When I restart batmand when tincd is still stopped, the OGM are processed and I see the neighbour nodes until I get the same error after about 1-2 minutes. good news, it does not block. Because of the error message I have inserted at posix/posix.c: 705 "return 0" (send_udp_packet()). I have tested two wrt54gl that had the problems before with the rev980 and the "return 0" statement. Both routers has be running for 18 hours when tincd was running without creating a connection. After that I called "kill -STOP $(pidof tincd)" on both routers. Both routers running now since 13 hours without problems. Please check and insert the "return 0" at posix/posix:705 if it is the right solution.

[B.A.T.M.A.N.] simple question
by giuseppe de marco 21 Feb '08

Does Batman run also on embedded devices with multiple interfaces? I mean: every link has one radio interface, but evey node can have multiple radio interface. That is, link are orthogonal in frequency. G -- Giuseppe De Marco, PhD Toyota Technological Institute

Re: [B.A.T.M.A.N.] Rev 972: batmand -c -d n hangs sometimes
by Freifunk Dresden 15 Feb '08

Hi Axel, I have done some checks. First I have added the tincd tap interface to a bridge and used the bridge as parameter for batmand. This is currently running since 10h. The second what I have tried is to call "kill -STOP $(pidof tincd)". On the WRT54GL batmand stopped quite fast, but it stopped also fast without the "kill". On the WRT54SL where I never have seen batmand stopping, the "kill" has stopped batmand after 5-10 minutes. I could reproduce this serveral times with the GS. When calling batmand -c -a 120.56.56.56/32 I get the following output on batmand -cd3: [ 275531] Unix socket: got connection [ 275539] got request: 10 [ 275540] Unix socket: Requesting adding of HNA 120.56.56.34/32 - put this on todo list... [ 275544] got request: 10 [ 275545] Unix client closed connection ... Three batmand processes are running and batmand -c returns: WARNING: You are using BatMan-eXp 0.3-alpha (compatibility version 10) ! /sbin/batmand [not-all-options-displayed] -r 2 -a 10.12.10.16/28 eth1 tbb After calling "killall batmand" only one of three batmand processes is killed. I have to killall -9 to get rid of it. Regards /Stephan

[B.A.T.M.A.N.] Rev 972: batmand -c -d n hangs sometimes
by Freifunk Dresden 14 Feb '08

Hi, I'm currently try using batmand-experimental Rev.972. I have encountered a strange behaviour. I'm running two WRT54 (GL and GS). Routing is working and there is enough memory. I have setup a cron job to call "batmand -c -d [2,7,8,9]" every minutes to update the status files on ramdisk. The webinterface then access the content of the status file which reduces the cpu load. The WRT54GS is working almost, but the WRT54GL hangs after a while as described below: The call to "batmand -c -d [2,7,8,9]" blocks batmand completely. batman does not do any routing and OGM processing. As result the router leaves the network. I can still call "batmand -c -r 3" and verify with "batmand -c" that the options were set. But OGMs are not processed. Any call to access the debug-information is blocked. After killall batmand and restart the call to "batmand -c -d x" is possible serveral times until batman hangs. The process list shows this "batmand -c -d x" - process. I have compiled batmand for whiterussian_rc6 and with the following options: (The email server has a problem with the assignment character so I have removed it in this email) CFLAGS -Wall -Os LDFLAGS -lpthread CFLAGS_MIPS -Wall -Os -DREVISION_VERSION $(REVISION_VERSION) LDFLAGS_MIPS -lpthread I had to remove the -pg option because it was not possible to compile. Also in whiterussian_rc the CFLAGS_MIPS/LDFLAGS_MIPS are not used (I think). Any Idea /Stephan

[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.] Kernel panic with batman-advanced, pinging remote nodes

Hi I've installed batman-advanced on a gaggle of Meraki minis, and run into a kernel panic when I ping a node over the mesh from my laptop (plugged into a meraki). The kernel I'm running is Linux OpenWrt 2.6.23.1 #3 Sun Feb 3 16:24:29 NZDT 2008 mips unknown The version of batman-advanced I'm running is B.A.T.M.A.N.
