11 Mar '09

Hello BM friends and developers, Concerning „B.A.T.M.A.N Status Report“ from June 28, 2007: •„2.1.7 Hiding Local Topology Information Beyond the Neighborhood“ How do I exactly set the TTL-Value for one or more of the specified interfaces? Thank You, Best Regards Peter

[B.A.T.M.A.N.] batmand ⇔ AF_INET6
by P. Mazart 11 Mar '09

Hello once again, BM does not let me go. Any complaints about sending badmand's broadcasts over ipv6? Has anyone experience with meshes and ipv6 autoconfiguration? Thanks, Greetings P.M.

Hi All I just installed OpenWRT and B.A.T.M.A.N. on 3 Fonera router (IPs are 192.168.2.200-201-202) Started BATMAN on each fonera Power of fonera limited to 9dBm (instead of 18dBm) since I'm experimenting in my small apartment Then I started BATMAN on my laptop (IP 192.168.2.65) This is the output of batmand -d 1 wlan0 Originator (#/255) Nexthop [outgoingIF]: Potential nexthops ...

[B.A.T.M.A.N.] Running Batman
by Kartik Muralidharan 03 Mar '09

03 Mar '09

Hi All, I was able to compile/link batman statically and configure using the instructions given by Sven LDFLAGS="-s -static" /usr/bin/make You can check it with `file batmand`. It should print something like batmand: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.8, stripped $ wlanconfig ath0 create wlandev wifi0 wlanmode adhoc $ iwconfig ath0 essid testnet $ iwconfig ath0 ap 02:00:de:ad:be:ef $ iwconfig ath0 channel 10 $ ip addr add $IP brd $BRDCAST dev ath0 $ ip link set ath0 up On running the command wlanconfig ath0 create wlandev wifi0 wlanmode adhoc I get the following output ath0: unable to register device ath0 I currently have 2 devices and use the following IP address configuration IP :192.168.1.10 & 192.168.1.11 BRDCAST: 192.168.1.255 Finally I run ./batmand ath0 This echos :Using interface ath0 with address IP and broadcast address BDCAST To test I tried pinging one device from the other, but it doesn't seem to work. Have I missed out something or is my configuration just wrong. Also whats the best way to test if the configuration and devices are running correctly. Thanks Kartik

[B.A.T.M.A.N.] [PATCH] Generate source dependency informations on the fly
by Sven Eckelmann 02 Mar '09

02 Mar '09

The current way to track dependencies in batman and related tools is to look for changes in the .c file and if it exist the .h file with the same name. This can lead to inconsistent compilations when changes are done in a header which is included in different .c files. The easiest workaround is to let the compiler generate the dependency information which is then included in the makefile to notice changes in directly and indirectly included files. The first run is made without these informations during the build of object files. No extra execve or gcc startup related overhead is generated in that way and future changes are still tracked by make.
