[B.A.T.M.A.N.] Problem with B.A.T.M.A.N. 0.3.1 rv1206 (compatibility version 5)
by Max 11 Apr '09

11 Apr '09

Good afternoon to everybody! I have to deal with 2 big problems occurred when I run batmand 0.3.1 rv 1206 in meshboxs equipped with OpenWrt Kamikaze 8.09 I detect the following problems: 1) B.A.T.M.A.N. daemon only works whether launched in debug mode. I'm sure about this because I'm monitoring the network with a packet sniffer. 2) When launched in debug mode (using the command batmand -d 3 ath0 &), the daemon starts to generate OGMs and to fill up its routing tables in a correct way. The problem occurs when I tries to ping an host in the network because the routing process uses the default routing table (that has not been modified by the batman daemon) and it is not aware on the correct batman routing tables. Does someone know how to solve these problems? Thank you in advance. Best regards, Massimo Reineri

[B.A.T.M.A.N.] Batman-adv nodes do not recieve OGMs
by Kai Timmer 01 Apr '09

01 Apr '09

Hello, i have a problem using batman-adv. At the moment i use v0.1, but i had the same problem when trying the svn version 1241. All the nodes send their ogm, but none does recieve any of these. What i did on all nodes is: iwconfig $wlaninterface essid batman mode ad-hoc and then echo "$wlaninterface" > /proc/net/batman-adv/interfaces echo 15 > /proc/net/batman-adv/log_level cat /proc/net/batman-adv/log after that shows somethink like this: Adding interface: ath0 Can't activate module: the primary interface is not active Sending own packet (originator 00:18:84:14:48:e5, seqno 1, TTL 50) on interface ath0 [00:18:84:14:48:e5] Sending own packet (originator 00:18:84:14:48:e5, seqno 2, TTL 50) on interface ath0 [00:18:84:14:48:e5] Sending own packet (originator 00:18:84:14:48:e5, seqno 3, TTL 50) on interface ath0 [00:18:84:14:48:e5] I also tried to set the channel on all nodes, but with no effect. Maybe someone can tell me what i do wrong. Thank you, -- Kai Timmer Email : email(a)kait.de Jabber: kai(a)kait.de Blog: http://blog.kaitimmer.de

[B.A.T.M.A.N.] Fragen zu Batman
by Raphaela Wrede 21 Mar '09

21 Mar '09

Kann mir jemand folgende Fragen beantworten: Ich fertige gerade eine Dipl. Arbeit zum Thema: "Leistungsanalyse des BATMAN Routingprotokolls für drahtlose Sensornetze" an der FU Berlin an. (Abgabe 11.5.) Es geht um einen Leistungsvergleich von OLSR und BATMAN. Hierfür habe ich jedes der beiden Protokolle für die Scatternet Platform der FU Berlin implementiert und sehr aufwändige realworld Tests bis zu eine Netzgröße von 15 Sensorknoten durchgeführt. Zusätzlich läuft eine andere Diplomarbeit, die das Ganze im Simulator untersucht, für eine größe Knotenanzahl, um Skalierbarkeit zu testen. Wie auch immer.. ich habe noch ein paar Fragen. Vielleicht hast du Zeit sie zu beantworten: 1.) Warum habt ihr BATMAN als Alternative zu OLSR entworfen? Das Argument, das ich kenne sind die widersprüchlichen Topologieinformationen bei Olsr, die zu Kreisrouten führen können. Aber was ist zum Beispiel mit dem Routing Traffic Overhead, bei großen Netzen.. wie verhält der sich. Wie stark wirkt sich das auf den Durchsatz aus? Ende-Zu-Ende Verzögerung... etc. Was war das gravierendste Problem nach eurer Erfahrung bei großen Netzen. Gibt es hierzu irgendwelche Dokumente.. Diagramme.. die ihr habt? Falls ja, wie wurden die Daten darüber gewonnen. 2.) Warum ist das RFC zu Batman abgelaufen? Warum läuft sowas überhaupt ab? Wie geht es diesbezüglich weiter? Leider kenne ich mich mit diesem Request For Comments Krempel nicht so gut aus.. Mein Betreuer meinte, dass es schlecht ist, sich auf ein abgelaufenes RFC zu berufen. 3.) Gewinnt Batman eher an Popularität in der Meshgemeinde oder ist eher das Gegenteil der Fall. Wo wird Batman noch eingesetzt? 4.) Wie mein Kommilitone und ich feststellen mussten, gibt es so gut wie keine offiziell veröffentlichten wissenschaftlichen Arbeiten zu BATMAN. Das ist ein kleines Problem, da es schwierig ist, sich auf andere Arbeiten bei bestimmten Behauptungen zu stützen. Hier dürfen nur offizielle Papers angegeben werden. Es gibt da ein Paper, wo du auch mitgewirkt hast, wo ein Leistungsvergleich zwischen OLSR und BATMAN in eine Realtestbed gemacht wurde. Aber leider scheint selbst dies nicht offiziell veröffentlich zu sein. Falls du mir irgendwelche Papers schicken kannst, wäre ich dir sehr dankbar. Vielen Dank. Raphaela

[B.A.T.M.A.N.] Why in my configuration batmand works only in debug mode?
by Max 20 Mar '09

20 Mar '09

Thank you Marek and Marco for your suggestions. I have solved the following problem: >2) When launched in debug mode (using the command batmand -d 3 ath0 &), the > daemon starts to generate OGMs and to fill up its routing tables in a > correct way. The problem occurs when I tries to ping an host in the network > because the routing process uses the default routing table (that has not > been modified by the batman daemon) and it is not aware on the correct > batman routing tables. Now I'm able to ping every originator in the network. The problem is derived from some iptables filters that stop the ping. Executing the following command I remove the filters solving the problem: iptables --flush iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT As concern the other problem it's still present. I'm working with meshboxes equipped with OpenWrt Kamikaze 8.09 and Atheros WiFi Cards. In my meshboxes, BATMAN sends OGMs only when it's launched in debug mode using the command "batmand -d 3 ath0 &". In this case, I see OGMs travelling in the network using Wireshark and the command "ip route ls table 66" lists all reachable batman nodes. Also for the other debug levels (i.e. 1,2,4,5) batmand works properly. On the other hand, when I launch the daemon in normal mode, using the command "batmand ath0", no error is displayed but no OGMs is observed to be travelling in the network using Wireshark. The only message displayed is: "Interface activated: ath0 Using interface ath0 with address 10.0.0.1 and broadcast address 10.255.255.255" Also the command "ip route ls table 66" does not produce any output. This morning I've installed the last version named B.A.T.M.A.N. 0.3.2-beta rv1235 (compatibility version 5) but I face again with the same problem. And finally another question... Is it normal to observe 3 different processes named batmand using the shell command ps even if I launched the daemon only once? Thank you in advance! Best regards, Massimo
