[B.A.T.M.A.N.] gateway-tunnel crashes with multiple net-dev
by tetzlav 29 Nov '07

29 Nov '07

Its me again... ;) At first i thought this is a problem with our complex setup on the freifunk-routers with olsr+batman on alias-interfaces and so on, but know i testet batman on my Laptop and have the same problems with multiple network interfaces and gateway-tunnels. I dont know how this gateway-tunnels really works, but i think this pseudo-NAT on gate0 not really works or send wrong source-IP or what else...

[B.A.T.M.A.N.] batmand still doesn't start the right way
by rene 25 Nov '07

Hi all, still having problem with batman. Mostly it starts without any problems, but sometimes it seems not to do what it should. In the following example, for instance, batmand sends OG-messages only through ath0:1 (192.168.41.186) and ath1:1 (192.168.42.186), but not through eth0:1 (which is the only interface where another batman-node, 192.168.40.184 is connected, OGs from this node are received). Any Ideas? Regards, Rene -------------------------------------------------------------------- root@OpenWrt:~# /etc/init.d/batmand start Starting batmand...

AW: [B.A.T.M.A.N.] wrong ip rules

Hi, > 6598: from all to 104.0.0.0/8 lookup olsr > 6599: from 104.0.0.0/8 lookup olsr > 6598: from all to 104.0.0.0/8 lookup olsr > 6599: from 104.0.0.0/8 lookup olsr > 6802: from 104.0.0.0/8 lookup 68 > batmand delete olsr-rules and set "from 104.0.0.0/8 lookup 68"!? which olsr-rules are deleted ? I can't see a difference there. In table 68 is the batman default route. All interfaces not controlled by batmand are routed towards this routing table. If you don't want that OLSR traffic is routed into the batman default route you have 2 choices: - You deleted the OLSR rules after each batmand start (hackish). - You use the --no-policy-routing option and set all rules by yourself. This option allows a tight integration into a firmware and full control of the policy routing. Why does batmand not recognize OLSR interfaces and ignores them ? We simply could not find a good solution for this kind of detection but we are open to suggestions. ;-) Greetings, Marek __________________________________ Ihr erstes Fernweh?

Hello *, I'm the author of the mipip olsrd patch mentioned by rene. The olsrd code was very close to doing the Right Thing (see below), my patch just fixed a few minor internal API issues that prevented it from working out correctly. I haven't seriously looked at the b.a.t.m.a.n. code, so I don't know exactly why it's causing problems for rene. Axel Neumann wrote: > IMO that does only work if the interfaces of a node are NOT connected to the > same physical/logical link (e.g. B1 and B2 are operating on different > channels or with different cell IDs,...).

But then you rather have layer 2 routing and not layer > 3. This is an interesting case. You're correct that in this configuration, a l3 routing daemon on A can't make a deliberate choice of which interface of B to send data to. This is obviously suboptimal, and should be avoided. However, there are plenty of cases where this will predictably not occur. For instance, in the opennet mesh network in Rostock, we have quite a lot of nodes which have one wired interface and one wireless interface, both of which are used for communication with other nodes in the mesh cloud. Assigning separate IP addresses to the different interfaces on those nodes would be wasteful of our address space. Imo, the choice whether to assign different IP addresses to the different interfaces on a specific meshnode should ideally lie with the (hopefully competent) network admins, and routing daemons should decently support either configuration, with the implicit understanding that having different interfaces a) in the same broadcast domain AND b) with the same IP addresses may lead to silent performance degradation. That's what the newer versions of olsrd do. Regards, Sebastian Hagen

Hi, starting batmand, the daemon sometimes doesn't seem to recognize the network the right way. root@25:~# killall batmand root@25:~# batmand eth1:1 vlan0:1 Using interface eth1:1 with address 192.168.42.25 and broadcast address 192.168.43.255 Using interface vlan0:1 with address 192.168.42.25 and broadcast address 192.168.43.255 ------------------------------------------------------- This is a tcpdump from a neighbor node: root@ap14:~# tcpdump -i eth0 src 192.168.42.25 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 05:12:09.512310 arp who-has 192.168.43.255 tell 192.168.42.25 05:12:10.512178 arp who-has 192.168.43.255 tell 192.168.42.25 05:12:11.699795 arp who-has 192.168.43.255 tell 192.168.42.25 ------------------------------------------- on the other node: root@25:~# killall batmand root@25:~# batmand eth1:1 vlan0:1 Using interface eth1:1 with address 192.168.42.25 and broadcast address 192.168.43.255 Using interface vlan0:1 with address 192.168.42.25 and broadcast address 192.168.43.255 root@25:~# ---------------------------------------------- tcpdump: 05:12:28.621940 IP 192.168.42.25.4305 > 192.168.43.255.4305: UDP, length 20 05:12:28.873246 IP 192.168.42.25.4305 > 192.168.43.255.4305: UDP, length 25 05:12:28.892343 IP 192.168.42.25.4305 > 192.168.43.255.4305: UDP, length 15 now batmand is running successfully. Any Ideas? regards, Rene

[B.A.T.M.A.N.] adding network announce
by Jan Hetges 18 Nov '07

Hi is that supposed to work? at least, first it says it does, but second it doesn't: root@bla:~# bmxd -c -a 172.16.x.x/32 WARNING: You are using BatMan-eXp 0.3-alpha rv802 (compatibility version 9) ! adding HNA 172.16.x.x/32, atype 1 bmxd -r 3 -a 172.17.x.x/24 eth1:bmx (172.17.x.x/24 is the network already announced at startup) cheers --Jan

[B.A.T.M.A.N.] parametrization for bmxd on ethernet?
by Jan Hetges 16 Nov '07

16 Nov '07

Hi I did'nt find doku on that. As i'm getting a 2nd GW :-)... setup: ---"DMZ" / vsat --- gateway ------ wifi-gw --- "wifi-world" --- 2nd-wifi-gw \ ---"wifi-world-2" I'm running bmxd-rv785 on all the wireless stuff, where wifi-gw runs bmxd -g -blabla, but i liked to move the bmxd-gw to the cabled gw, so if the sat-link fails, "wifi-world-2" and "DMZ" can still reach the internet through the 2nd-wifi-gw. So howto parametrize bmxd for devices without wireless-intrerface? Can i use --gateway-change-hysteresis together with -p ? Suggestion: in bmxd -cbd1 i saw nodes with lvld >400 before they get deleted, i think 180 should be more than enough, 3 minutes is plenty of time for normal reboot, and if a node dosn't send OGMs for more than that... it has a serious problem ;) cheers --Jan

[B.A.T.M.A.N.] WICHTIG/IMPORTANT - freifunk-batman: Sicherheitslücke/security problem
by Lui 16 Nov '07

[english below] Hallo! die beiden bislang aktuellen freifunk-batman Pakete (0.83.1 und 0.84beta02) haben leider eine derart fette *Sicherheitslücke* (Dank an Jo-Philipp Wich [Leipzig] für den Hinweis!), daß eine UMGEHENDE Aktualisierung DRINGEND angeraten ist! Die gefixte Version (auf Basis von "0.84") findet sich als: http://freifunk.schmudde.com/ipkg/freifunk-batman_0.2-0.84.10.ipkg (Hinweis: weiterhin /nur/ batmand *0.2* - daher der Versions#-"zusatz") Hintergründe - gibt's dann später... Bitte informiert auch Leute, die es auf diesem Weg u.U. nicht erreicht... Danke & sorry Lui --- Hello! the freifunk-batman packages up to version 0.84beta02 have a huge security problem (thanks to Jo-Philipp Wich [Leipzig] for the note). So, an IMMEDIATE update is highly recommended! Find the fixed Version (based on "0.84"), as: http://freifunk.schmudde.com/ipkg/freifunk-batman_0.2-0.84.10.ipkg (Note: This is still a batmand *0.2-only* packet - now indicated by the version-string) Backgrounds: after a while... Please forward this information to people who may not get it this way. Thanks & sorry Lui

Today I tried batmand 0.3-beta rv791 (on ASUS-WL-500gPremium) and noticed that batmand set definitly wrong ip rules or has problems with alias-Interfaces and/or olsrd: > root@17-3:~# ip addr show eth2 > 4: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc prio qlen 1000 > link/ether 00:90:4b:7d:20:7a brd ff:ff:ff:ff:ff:ff > inet 104.61.17.3/8 brd 104.255.255.255 scope global eth2 > inet 10.61.17.3/24 brd 10.61.17.255 scope global eth2 > root@17-3:~# ip rule > 0: from all lookup local > 6597: from all lookup main > 6598: from all to 104.0.0.0/8 lookup olsr > 6599: from 104.0.0.0/8 lookup olsr > 32766: from all lookup main > 32767: from all lookup default > root@17-3:~# ip addr add dev eth2 105.61.17.3/8 broadcast + label eth2:bat > root@17-3:~# ip addr show eth2 > 4: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc prio qlen 1000 > link/ether 00:90:4b:7d:20:7a brd ff:ff:ff:ff:ff:ff > inet 104.61.17.3/8 brd 104.255.255.255 scope global eth2 > inet 10.61.17.3/24 brd 10.61.17.255 scope global eth2 > inet 105.61.17.3/8 brd 105.255.255.255 scope global eth2:bat > root@17-3:~# batmand -r2 eth2:bat > Using interface eth2:bat with address 105.61.17.3 and broadcast > address 105.255.255.255 > root@17-3:~# ip rule > 0: from all lookup local > 6597: from all lookup main > 6598: from all to 104.0.0.0/8 lookup olsr > 6599: from 104.0.0.0/8 lookup olsr > 6600: from all to 105.0.0.0/8 lookup 66 > 6699: from all lookup 65 > 6700: from all to 105.0.0.0/8 lookup 67 > 6800: from all iif lo lookup 68 > 6801: from 127.0.0.0/8 lookup 68 > 6802: from 104.0.0.0/8 lookup 68 > 6803: from 104.0.0.0/8 lookup 68 > 6804: from 192.168.1.0/24 lookup 68 > 32766: from all lookup main > 32767: from all lookup default batmand delete olsr-rules and set "from 104.0.0.0/8 lookup 68"!?
