[B.A.T.M.A.N.] dynamic gateway / hna / services

hi, Question 1: how does batmand detect whether the internet connection is really connected to the internet or not. Or does batmand just relays on the -g parameter. Until now we let run a cron job that checks for the real working gateway. Because we can not relay on the presence of the default route. User may use a different router to connect to the internet and just add the default route this private router. The problem is that the node offering a internet connection (-g) should also be able to access other internet connection if its local connection is brocken. Question 2: I'm currently checking how the HNA is working, but until now I can not see any HNA on a second node. Firewall is enabled completely for both nodes and each node sees the other nodes. I call batmand as follow: Node1: batmand -t 63 -a 141.56.0.0/16 wlan0 bbs /t 2 bbc /t 2 Node2: batmand -t 63 eth1 bbs /t 2 bbc /t 2 But batmand -c -d 4 does not show any HNA messages and no HNA entry is stored in routing table. Beside of this the Idea to add/delete HNA without stopping batmand would be good. e.g. batmand -c -a <add-hna> batmand -c -A <del-hna> Question 3: If a node offers a ftp server (portforwarding) I like to offer this "service" via batmand like olsrd. A generic solution would be good to just allow to send user text messages with the OGM. e.g:sending: batmand -c -m "this is my message" (called requlary by cron.d to send/update a message or command) the running batmand will need an addional options e.g. -m (script) that is called to process the incomming message. e.g: batmand -m process-message-script wlan0 The advantage would be, that each user that is using batman can offer different services: e.g. populate a service list, news, software updates,.... Another Idea of the "-m" is to differenciate this parameter to -M <"message"> and -m <send-script>. by calling batmand -c -m send-script, batmand can setup stdin/stdou as binary file handle and fill a user-OGM with binary data that is then send. Please tell me if some of the features already present in the batman-experimental trunk. Kind regards Stephan
