Hi Freifunk

I don't know if you have a typo in your mail but starting batmand as

/usr/sbin/batmand -g 0 -r 0 eth2

means you do not want set any default route (-r equal 0). Moreover, using -g equal 0 means disabling gateway functionality for the node (normally -g 0 is used on a recpeater/client node only).

What revision are you running and what 0.3 branch (beta or experimental)? We use beta branch rv674, now migrating to latest rv719 for test purposes).

hello batmen, ;)

here in berlin NE we are about to update the batmands on our backbone to 0.3.0 . atm our net is mainly running on olsr and batman in parallel for testing purpose. after some changes in the net we got heavy HNA-hopping with olsr which is related to the improper metric in our case. therefore we are somewhat forcing the migration to batman and got some strange default routes with the most recent 0.3.0 builds on some routers:

root@OpenWrt:/etc/init.d# route -n Destination Gateway Genmask Flags Metric Ref Use Iface [...] 0.0.0.0 0.0.0.0 0.0.0.0 ! 0 0 0

[...]

batmand has been started with the following parameters: /usr/sbin/batmand -g 0 -r 0 eth2

after appearance of this default-route olsr-"clients" cannot use the uplink anymore, so further testing is difficult. we have another problem with this build, but cannot investigate further because of this behaviour. so any help is appreciated.

thanks

I'm sorry to say that 0.3beta is not usable at the moment. We are in the status of bug-hunting.

Hello Marek,

we used rev718 ... from yesterday evening ... and all facts you mentioned are right ... we disabled anything that enables batman to set or announce default routes ... thats why we completely don't understand whats happening there. and because the same things happens on a slackware/i386 node AND on an openWRT_post7.09/ixp4xx but not on an openWRT_pre7.06/i386 the failure is not likely to be in the operating system.

in the evening i'll post what you asked for ... atm i am not in reach of the equipment ...

greets dennis bartsch

Hi,

...

root@OpenWrt:/etc/init.d# route -n Destination Gateway Genmask Flags Metric Ref Use Iface [...] 0.0.0.0 0.0.0.0 0.0.0.0 ! 0 0 0 * [...]

batmand has been started with the following parameters: /usr/sbin/batmand -g 0 -r 0 eth2

as Antonio said you disabled all internet traffic via batman. Furthermore, default routes created by batman are found in table 68 (use "ip route ls table 68" to see its content) but "route -n" shows you table 254.

...

need some hunters ? :)

Soon! If you have a mesh with a couple of boxes with more than one batman-interface (linked by ethernet or multiple radios) we'll be more than happy to learn about your results.

We just have found one important bug, I think. But it is not fixed yet.

We'll post a message to the list as soon as we think it is fixed and worth a try.

Looking forward to the results!

Cheers!

Hi,

the problem semms to be found and very much trivial. the recent openWRT-release (or especially the ixp4xx-port ?!) as well as the rather old slackware10.2 comes _without_ policy-routing compiled into the kernel. figure this out ... an OS for embedded routers comes without advanced routing capabilities ... nothing i've expected. nevertheless batman should detect this and give a hint rather than trying to write to non-existent routing-tables.

this sounds odd. A check for policy routing seems to be a good idea but does anyone know how to check that ?

Regards, Marek

i did a test on 12 nodes (two with 2 radios) with rv726 last night (which was not that successful). after i put everything back to "productive setup" with 0.2-rv502, i still had a problem on one of the two-radio-boxes with the 2nd radio that might be related (seems all ogm's entering that iface were ignored from time to time). rebooting fixed it and rv502 works like before.

cheers

hey,

installation of the latest development-ipkgs (at least the i386 ones) of 0.3-beta fails, because control.tar.gz is missing:

Hmm, the tgz in that folder is a tgz :-) I think there has never been a ipk in the development/i386 folder - maybe there should. Anyway, there are ipk packages for i386 here: http://downloads.open-mesh.net/batman/development/misc/batmand_0.3-beta-curr... or here: http://downloads.open-mesh.net/batman/development/misc/batmand_0.3-beta-curr...

If you can confirm that its working for i386-kamikaze I'll open a deveopment/i386-kamikaze folder.

how about just maintaing the batman package in kamikaze?

Yesterday you also mentioned some problems with the binary packages for ARM CPUs. Ipkg and tgz can be found here: http://downloads.open-mesh.net/batman/development/armv5te/ Unfortunately, I do not remember the exact problem description ;-)
