[B.A.T.M.A.N.] [PATCH] batman-adv: pass the correct header size to interface_rx
by Antonio Quartulli 01 Feb '12

01 Feb '12

in recv_unicast_frag(), the third parameter of the interface_rx() invocation, which is the size of the current header, is wrongly computed.

[B.A.T.M.A.N.] ap_isolation issue
by Andre Courchesne 31 Jan '12

31 Jan '12

Hi, We are trying to get OpenWRT with batman-adv 2011.4.0 to play nice using ap_isolation. However as soon as ap_isolation is turned on the meshed ap are not acessible anymore by our Linux firewall on which at least 1 ap node is physically connected. The following pastebin post shows the exact configuration and details: http://pastebin.com/2bghWLkp Any clues ? Thanks, Andre

[B.A.T.M.A.N.] Wireless Battle Mesh v5 - Call for papers
by Marek Lindner 29 Jan '12

29 Jan '12

Wireless Battle Mesh v5 - Call for papers ========================================= Wireless Battle Mesh v5 is at hand and it is time to bring together the agenda. As last year's attempts to construct an agenda was well received and provided the grounds for numerous healthy discussions the broad majority asked for similar action. However, the number of talks is going to be reduced to leave more time for individual discussions and testing. Submission ========== To allow an efficient handling of your submission, please provide the following information and send them to me directly in form of an email: * your name * the type of your slot (talk/workshop/panel discussion/lightening talk) * your topic headline * your topic description which can brief (does not need to exceed a couple of lines) but should provide a reasonable summary of your talk * the dates of your stay at the event + (optional) preferred day for your slot * length of the slot if you wish to do a workshop (all other slots will be limited to one hour - notify me in advance if you think that is not enough for you) Feel free to contact me with your ideas in case you are unsure about your topic. Last year's agenda also should be able to provide some insights: http://battlemesh.org/BattleMeshV4/Agenda Deadlines ========= Submissions are accepted until and including the 16th of March. Everyone missing this deadline still has the opportunity to apply for a lightening talk slot. These slots can be acquired by simply contacting me during the event. The list of registered lightening talks will be published in the battlemesh wiki. The final program will be made available in the aforementioned wiki during the second week of March. If you have any question or suggestion, please let me know. Regards, Marek

[B.A.T.M.A.N.] Disconnecting the nodes in batman-adv
by Bouterse, Robert 26 Jan '12

26 Jan '12

My attempts to use the hop_penalty failed, since I do not have control over the RF environment. So, I am resurrecting an old thread to find out if this is possible : https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2011-July/005058.html The state of the thread seems to have ended with the idea of wrapping a wlan0 interface in a bridge, and then adding the bridge to a batman-adv network. This worked (apparently) with batman-adv over ethernet, but will not work over 802.11 because the kernel specifically prevents the bridge from being created, http://lists.shmoo.com/pipermail/hostap/2010-January/020959.html There is some mention that batman-adv has ebtables support. How can I get at that, to do what the people in the thread, were trying to accomplish? /*----------------------------------------*/ Bob Bouterse Senior Software Engineer Multimedia Development Center D&M Holdings Inc. http://www.dm-holdings.com

[B.A.T.M.A.N.] [PATCH] batman-adv: fix initialised flag for tt request/responses
by Simon Wunderlich 26 Jan '12

26 Jan '12

When receiving a tt_response, we first delete the old entries and set the initialised flag to false, then add the new received entries, but forgot to set the initialised flag to true again. This may lead to endless loops of requests/responses, as a request is always issued if the initialised flag is not set. Fix this by moving initialised = true from tt_update_changes() to _tt_update_changes().

We have a quick-start-guide on our website along with numerous other documents. Did you have a look at that ? If that is not enough you need to be more detailed on what you are looking for.

The event aims to bring together people from across the Globe to test the performance of different routing protocols for ad-hoc networks, like Babel, B.A.T.M.A.N., BMX, and OLSR. If you are a mesh networking enthusiast, community networking activist, or have an interest in mesh networks you have to check this out! Informations about the event are gathered at: http://battlemesh.org/BattleMeshV5 Location ======== The (optional) WBMv5 Warmup event takes place in Sarantaporo (rural area in range of the Olympus mountain). The main event happens at the National Technical University of Athens (NTUA) in the very center of Athens. Registration ============ Registrations will be available at different hackerspaces (Fusolab, HSBXL, /tmp/lab, metalab, CCC, ...) and on the official website for the event at: - http://battlemesh.org/BattleMeshV5_Warmup - http://battlemesh.org/BattleMeshV5 Fees ==== The warmup requires a small fee to cover the transportation costs to Sarantaporo. The main event is free of charge. We offer the possibility to reserve a low-cost bed close to the NTUA for you. Spread the word =============== Feel free to spread the word by forwarding this mail to all lists / people that might be interested in it. Also blogging about the event is more than welcome!

Re: [B.A.T.M.A.N.] Manual route manipulation [SOLVED]
by Bouterse, Robert 18 Jan '12

18 Jan '12

Sorry, I figured this out myself. Changing the value of /sys/class/net/bat0/mesh/hop_penalty allows me to create artificially "desirable" nodes. So, I have set the hop_penalty as: A=10 B=1 C=5 D=10 ________________________________________ From: b.a.t.m.a.n-bounces(a)lists.open-mesh.org [b.a.t.m.a.n-bounces(a)lists.open-mesh.org] On Behalf Of Bouterse, Robert [robert.bouterse(a)dmh-global.com] Sent: Wednesday, January 18, 2012 12:59 PM To: b.a.t.m.a.n(a)lists.open-mesh.org Subject: [B.A.T.M.A.N.] Manual route manipulation Hi, I am new to the BATMAN list, and I need some help, I am running some feasibility tests on batman-adv for our use. I need to test how well it reroutes traffic when an intermediate node goes away. I need to set up a mesh in a diamond pattern, like: |---->B<----| A<--{ }--->D |---->C<----| Then find out if traffic is being routed through the B node, shutdown the B node, and see that the route "heals" to using node C instead. I was able to do this on open80211s by using the "iw station set plink_action block" command to force the A node to never communicate directly with the D node, and wireshark to verify the communications. Does anyone know of a way of doing these types of path manipulations with batman-adv? I didn't see anything in batctl that looked like it would work. Maybe there are /sys or /proc entries? /*----------------------------------------*/ Bob Bouterse Senior Software Engineer Multimedia Development Center D&M Holdings Inc. http://www.dm-holdings.com
