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!
cheers,
doc
