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

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

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

[B.A.T.M.A.N.] get the branches explained
by Marek Lindner 06 Feb '08

06 Feb '08

Hi, in the last months many new branches were created and many numbers are floating around which caused much confusion. Here comes a brief summary why these branches and numbers were created, what they are good for and who is behind it: Whenever we mention Roman numerals (as II or III) we speak of B.A.T.M.A.N.'s routing algorithm version. It describes how the routing information are flooded and how they are handled to make the best routing decission possible. Arabic numerals are used to distinguish the version of our implementation. Next to the routing algorithm many features and goodies are added to simplify the users life. Example: batman 0.2 uses the B.A.T.M.A.N. III routing algorithm. === batman-0.2 === [Maintainer: Marek Lindner, Axel Neumann] - 0.2 stable was created last summer and represents our implementation of the BATMAN III routing algorithm. It works quite well and stable but has a major flaw while routing strong asymetric links. That is why we began working on a new algorithm - 0.2 is to be deprecated soon. === batman-0.3 === [Maintainer: Marek Lindner, Andreas Langer] - The 0.3 branch brought a bunch of new features and updates to 0.2, especially a newly designed routing algorithm. It seems rather stable but needs some more testing before replacing the current stable version. === batman-experimental (aka bmx) === [Maintainer: Axel Neumann] - This branch kept the 0.2 routing algorithm and tried to overcome its flaws by extending it. Despite its name it is neither specifically unstable nor contains the latest features for the 0.3 branch (we are not debian ;-) ). Under the hood it shares much code with 0.3 - not more or less. === batman-advanced (aka batman-adv aka batman-adv-userspace) === [Maintainer: Simon Wunderlich, Marek Lindner] - In April 2007 batman advanced (residing in user space) came to light. It was a layer 2 implementation of batman 0.2. Since then it was continuously worked on and uses the batman 0.3 routing algorithm today. It builds a switch of all your nodes and enables you to ran any protocol (IPv4, IPv6, ..) on top of it. === batman-saxnet (merged back into batman-adv-userspace) === [Maintainer: www.saxnet.de] - In autumn 2007 Saxnet (a German company) wanted to use our layer 2 implementation for their products. They tested, fixed and improved our layer 2 implementation. Therefore they got an extra branch which was merged back into our batman advanced userspace branch. === batman-adv-kernelland === [Maintainer: Marek Lindner] - Due to the testing we realized that the layer 2 implementation in user space suffered from many performance problems. In late 2007 we ported our layer 2 implementation to kernel space in form of a kernel modul. At the moment it is heavily worked on and a release is to be expected in the coming weeks. === battools === [Maintainer: Andreas Langer] - The battools are a set of debugging tools which work together with our layer 2 implementation (user space and kernel land). You can use them to debug the mesh which proved to be difficult without them. Regards, Marek

[B.A.T.M.A.N.] Rev 972: VIS not working
by Freifunk Dresden 02 Feb '08

02 Feb '08

Hi, I'm currently try using batmand-experimental Rev.972. First the visualisation server does not show any connections. Have two routers with batmand-exp rev 972 running. It seems that this batman version is not compatible with the vis-server. When I use the old version of vis, I get the dot information when I call "telnet localhost 2004". I assume that the batman-exp implementation still uses the old compatibility version for vis. /Stephan

[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) . I could get the expected results when i am using tun instead of kmod-batgat . but when i use kmod-batgat even tho the tunnel gate0 is established the routing rules and firewall is same as with kmod-tun i cant get traffic thru gate0 My Setup: ---- Wired - - - - WiFi 192.168.111.1-----(WAN)-192.168.111.74(Gateway)10.1.125.158 - - - - - - 10-1-125-158 (Node2) *With kmod-batgat:* from ping 192.168.111.1 -I gate0 ##on gateway root@10-1-125-158:~# lsmod |grep batgat batgat 10976 1 ##Ping from Node root@Node2:~# ping 192.168.111.1 -I gate0 PING 192.168.111.1 (192.168.111.1): 56 data bytes --- 192.168.111.1 ping statistics --- 46 packets transmitted, 0 packets received, 100% packet loss ##tcpdump on node root@10-1-125-158:~# tcpdump -i gate0 proto \\icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on gate0, link-type EN10MB (Ethernet), capture size 96 bytes 0 packets captured 0 packets received by filter 0 packets dropped by kernel *With kmod-tun:* root@10-1-125-158:/# lsmod |grep tun tun 6592 1 *##on Node* batman -cd2 Gateway (#/255) Nexthop [outgoingIF], gw_class ...
