Hey again,

...sorry I forgot to mention: you need tun support loaded into your kernel and the libpthread library (but the latter should be default on most i386 based machines).

Hey Dragan,

#!/bin/sh iwconfig eth2 mode ad-hoc essid olsr.freifunk.net channel 10 ap 02:CA:FF:EE ifconfig eth2 104.130.30.9

(just to be shure) this should be 02:CA:FF:EE:BA:BE

..

i am starting batman with:

#!/bin/bash iwconfig eth2 mode ad-hoc essid olsr.freifunk.net channel 10 ifconfig eth2 105.130.30.9 ifconfig eth2 up sleep 1 batmand -d 1 -p 105.131.41.5 -r 1 eth2

can you start batmand in background with: batmand -r 1 -p 105.131.41.5 eth2 instead and tell if the problem continues. This command instantly returns your prompt but a: ps -aux | grep batmand should show the running main-daemon in the background. Also please check that there are no predefined host routes for the 105.0.0.0/8 network before you start batmand and after it stopped. Meaning a: route -n | grep ^105 berfore and after the daemon is running should only show: 105.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 eth2 While batmand is running it should of course show routing entries for all other known batman nodes but if such host routes are still there after the daemon stopped it is a definitive sign for an uncorect termination of teh daemon.

#!/bin/bash batmand -c -d 2

in another terminal.

It should of course always be possible to access the debug output from the running batmand main-daemon by launching a batmand-client with batmand -c -d <1-4> or in batch mode (providing just a single outputpage and returns to the prompt) with: batmand -c -d <1-4> -b However, it would be interesting to know if the crash is related to existence of a batmand-client connecting to the main daemon. For example for batmand-0.2.0-rc2-rv350 (and before) debug level 4: batmand -c -d 4 is known to cause the batmand to crash after a short time and it might be possible that this problems also occur with other debug-levels. Try batmand -c -d 1 and batmand -c -d 2 instead.

ciao, axel

when batman starts, the 'batmand -c' script shows, that i am connected to another gateway, but not to preferred one:

 Gateway              Router (#/128)

=> 105.192.99.62 105.130.30.1 ( 3), gw_class 10 - 6 MBit, reliability: 0 105.192.99.61 105.130.30.1 ( 1), gw_class 7 - 2 MBit, reliability: 0 105.131.83.5 105.130.30.1 ( 1), gw_class 11 - >6 MBit, reliability: 0 105.131.41.5 105.130.30.1 ( 2), gw_class 11 - >6 MBit, reliability: 0 105.192.99.103 105.130.30.1 ( 3), gw_class 7 - 2 MBit, reliability: 0 105.192.99.192 105.130.30.1 ( 2), gw_class 10 - 6 MBit, reliability: 0

...........

this always is a number 105.192.99.....(.62, .103, .192). this condition than stays for 2 or 3 up to 10 minutes, and in that time i cannot even ping the 105.130.30.1 which is the next point here.

after some minutes, the connection changes, so that 'batmand -c' shows that i am connected to 105.131.41.5 and i am able to ping 141.1.1.1. unfortunately, after some minutes (or even shorter), the batman script stops and the terminal is at the prompt again. there is no segfault, using 'ulimit -c unlimited' will not produce a core-dump. i suppose that this is not a driver bug, cause looking at this moment at 'dmesg', i can see that the driver is loaded using the 02:ca:ff:ee:ba:by - if i stop batmand and start olsrd, i will be connected to the internet as expected.

i am really not aware of what else information i could provide to you, in order to make batmand running stable here, but if you have any idea, please let me know!
