Re: [B.A.T.M.A.N.] How to force a specific network topology
I have looking for a solution, but I think that it is imposible do this for this way. This topic talks about it: https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2011-July/005167.html and Sven talks about two diferent ways: change the driver of mac80211 in order to be compatible with 4addr mode or make a transparent bridge(that I don't know how do it) Other solutios would be simulate the network, or add a OMG filter patch to batman-adv. Am I correct? Regards 2012/9/13 Esteban Municio emuni...@gmail.com: Hi again I'm still having problems with this issue I can not bridge wlan0 for use ebtables.Now I am bridging without eth0, only with the wireless interfaces. With the device freshly rebooted and with empty /etc/rc.local : brctl addbr bridgeWlan brctl addif bridgeWlan wlan0 brctl: bridge bridgeWlan: Operation not supported I searched for this I found that you can set this if you do: iw dev wlan0 set 4addr on but you only can do this if your wireless interface is in mode ap, and mine is on adhoc. So I can't set the bridge with batman (batctl if add bridgeWlan) This is my wireless device configuration in /etc/confiog/wireless config wifi-iface option device radio0 option network lan option mode adhoc option ssid netmesh option encryption none ¿Do you know how could I set the bridges correctly for ebtables filtering? Thanks! Regards Esteban 2012/9/10 Esteban Municio emuni...@gmail.com: Thanks you very much Gui and Sven Now I understand the configuration and install ebtables has seem quite simple.

Re: [B.A.T.M.A.N.] How to force a specific network topology
Hi Martin Thanks you, I have seen the description and I think that your patch is what we are looking for. I'm gonna try to test it, but I'm a totally newbie in patches issues. Could you tell me superficially what I have to do for rebase the patch before to build it and add it to our nodes?

Hi list Is there any way to block some links between nodes in order to force a specific network topology in batman-adv? Por example, if y have 3 nodes A, B, C and I want to create a string topology A - B - C, where A can not connect directly with C, how could I get it without move far away the nodes? Thanks you!
