[B.A.T.M.A.N.] Manually Updating Translation table
by Kartikeswar K 16 Aug '17

16 Aug '17

Dear BATMAN Community members, I am new to BATMAN Mesh network and looking forward for answer to my query related to updating Local Translation Table in a BATMAN Node. I would like to make a mesh network where I would like to update the client entry in Local Translation manually. Is it possible to add the entry manually in translation table? If so, I would like to know how can I update this table in BATMAN from user space? Thanks in advance and would appreciate your responses. Thanks & Regards, Kartikeswar Koppula kartikeswar(a)gmail.com

[B.A.T.M.A.N.] No bandwidth over wired Batman mesh network
by Mattias Vanhoutte 10 Aug '17

10 Aug '17

Hi, I am trying to use B.A.T.M.A.N. on a wired mesh network (ethx interfaces) version: batctl 2017.0 [batman-adv: 2017.0.1], but I got very/no bandwith over the BATMAN interfaces. I have PC1 which is Intel based, 64 bit, kernel 4.9.0-3-amd64, OS is Debian, build batman from sources: - eth0 10.1.98.250/24 address - bat0 172.16.100.250/24 address I have PC2 which is ARM based, 32 bit, kernel 4.6.0-xilinx-v2016.3, OS is yocto build, build batman from sources - eth0 10.1.98.3/24 address - bat0 172.16.100.1/24 address PC1 and PC2 are directly connected with ethernet cable (no switch in the network) I did network measurements with iperf (TCP and UDP) between PC1 and PC2 in 2 conditions: - Without using batman, I got symmectric bandwidth between PC1 and PC2 (measured TCP and UDP on ethx interface), TCP bandwidth is 300-400 Mbits/sec - With using batman, I got something strange: bandwidh PC1 -> PC2 is 22 Kbit/sec and bandwidth PC2 -> PC1 is 110 Mbit/sec (measured TCP on bat0 interfaces) Also for UDP measurements I got bandwidth=0 measured PC1 -> PC2 and 222 Mbit/sec PC2 -> PC1 There is no firewall active on both devices. Does anybody has an idea why I got no bandwidth in 1 Direction? Is there something I should configure when I build and want to use batman on 2 different types of operating systems / CPU? I also did tests between 2 devices of type PC2, then I got symmetric bandwidths in both directions: - without using batman: 430 Mbits/s in both directions PC1 <> PC2 - with using batman: 125 Mbit/s in both directions PC1 <> PC2 So here I see a large drop of the TCP bandwidth by using batman 430 -> 125 Mbit/s. Is this normal behavior? Can anybody tell me where and how I can see debug messages from Batman? Kind Regards, Mattias Vanhoutte

[B.A.T.M.A.N.] help regarding interfacing b.a.t.m.a.n with mininet-wifi
by Abhinanda Dutta 02 Aug '17

02 Aug '17

Hi, I am currently trying to interface batman with an emulator called Mininet-wifi. My emulator is emulating the wifi-direct where there are 4 mobile stations and there are 2 wlan. I am trying to use batman for routing so that I can ping between stations which are not in the same wlan through a hop. The problem I am facing is though batctl functions are working fine, it is not interacting with the real mininet-wifi environment. By that I mean if I use batctl tr MAC_ADDRESS it traces the route between nodes even if they are on 2 different wlan or batctl p MAC_ADDRESS pings the 2 stations. However if I try to see the route in the real Linux terminal using route or watch route command it doesn't show the route or ping between stations. Is there any way to make batman-adv interact with the real mininet-wifi environment. Thanks, Abhinanda
