NAME

       batmand - better approach to mobile ad‐hoc networking

SYNOPSIS

       batmand [options]interface[interface...]

DESCRIPTION

       B.A.T.M.A.N  means better approach to mobile ad‐hoc networking, this is a new routing protocol for multi‐
       hop ad‐hoc mesh networks. Go to https://www.open-mesh.org/ to get more information.

       The following document will explain how to use the batman daemon.

       The batmand binary can be run in 2 different ways. First you need  to  start  the  daemon  with  "batmand
       [options] interface" (daemon mode) and then you can connect to that daemon to issue further commands with
       "batmand  -c  [options]" (client mode). Some of the options below are always available, some are not. See
       the example section to get an idea.

OPTIONS

       -a add announced network(s)
              Add networks to the daemons list of available connections to another network(s). This  option  can
              be  used  multiple  times and can be used to add networks dynamically while the daemon is running.
              The parameter has to be in the form of ip‐address/netmask.

       -A delete announced network(s)
              Delete networks to the daemons list of available connections to another  network(s).  This  option
              can  be used multiple times and can only be used while the daemon is running. The parameter has to
              be in the form of ip‐address/netmask.

       -b run debug connection in batch mode
              The debug information are updated after a period of time by default, so if you use  "-b"  it  will
              execute  once  and then stop. This option is useful for script integration of the debug output and
              is only available in client mode together with "-d 1" or "-d 2".

       -c connect via unix socket
              Use this option to switch to client mode. Deploy it without  any  arguments  to  get  the  current
              configuration even if changed at runtime.

       -d debug level
              The debug level can be set to five values.
                        default: 0 -> debug disabled
                 allowed values: 1 -> list neighbors
                                 2 -> list gateways
                                 3 -> observe batman
                                 4 -> observe batman (verbose)
                                 5 -> memory debug / cpu usage
              Note that debug level 5 can be disabled at compile time.

       -g gateway class
              The  gateway  class  is used to tell other nodes in the network your available internet bandwidth.
              Just enter any number (optionally followed by "kbit" or "mbit") and the  daemon  will  guess  your
              appropriate gateway class. Use "/" to separate the down‐ and upload rates. You can omit the upload
              rate and batmand will assume an upload of download / 5.
                        default: 0 -> gateway disabled
                 allowed values: 5000
                                 5000kbit
                                 5mbit
                                 5mbit/1024
                                 5mbit/1024kbit
                                 5mbit/1mbit

       -h short help

       -H verbose help

       -o orginator interval in ms
              A  node  transmits  broadcast  messages  (we  call  them  originator message or OGM) to inform the
              neighboring nodes about it's existence.  Originator interval is the time to wait after sending one
              message and before sending the next message. The default value is 1000 ms (1 second).  In a mobile
              network, you may want to detect network changes very quickly, so you need  to  send  message  very
              often, for example, use a value of 500 ms.  In a static network, you can save bandwidth by using a
              higher value.  This option is only available in daemon mode.

       -p preferred gateway
              Set  the  internet gateway by yourself. Note: This automatically switches your daemon to "internet
              search modus" with "-r 1" unless "-r" is given. If the preferred gateway is not found the  gateway
              selection will use the current routing class to choose a gateway.

       -r routing class
              The  routing class can be set to four values ‐ it enables "internet search modus". The daemon will
              choose an internet gateway based on certain criteria (unless "-p" is specified):
                        default: 0 -> set no default route
                 allowed values: 1 -> use fast connection
                                 2  -> use stable connection
                                 3  -> use fast‐switch connection
                                 XX -> use late‐switch connection
              In level 1, B.A.T.M.A.N tries to find the  best  available  connection  by  watching  the  uplinks
              throughput  and  the  link  quality.   In  level  2,  B.A.T.M.A.N compares the link quality of the
              internet node and chooses the one with the best link quality.  In level  3,  B.A.T.M.A.N  compares
              the  link quality of the internet node and chooses the one with the best link quality but switches
              to another gateway as soon as a better connection is found.  In level XX  (number  between  3  and
              256)  B.A.T.M.A.N compares the link quality of the internet node and chooses the one with the best
              link quality but switches to another gateway as soon as this gateway has a TQ value  which  is  XX
              better than the currently selected gateway.

       -s visualization server
              Since  no  topology database is computed by the protocol an additional solution to create topology
              graphs has been implemented, the vis server. Batman daemons may send their local view about  their
              single‐hop  neighbors to the vis server. It collects the information and provides data in a format
              similar to OLSR's topology information output.  Therefore  existing  solutions  to  draw  topology
              graphs developed for OLSR can be used to visualize mesh‐clouds using B.A.T.M.A.N.

       -v print version

       --disable-client-nat
              Since  version  0.3.2  batmand  uses  iptables  to set the NAT rules on the gateX interface of the
              batman client (-r XX). That option disables this feature of  batmand  and  switches  the  internet
              tunnel  mode  to  "half tunnels" (the packets towards the gateway are tunneled but not the packets
              that are coming back) unless NAT was enabled manually. Be sure to know what you are doing! Without
              NAT the gateway needs to have a route to the client or the packets will be dropped silently.

       --policy-routing-script
              This option disables the policy routing feature of batmand ‐ all routing changes are send  to  the
              script  which  can  make  use of this information or not. Firmware and package maintainers can use
              this option to tightly integrate batmand into their own routing  policies.  This  option  is  only
              available in daemon mode.

EXAMPLES

       batmand eth1 wlan0:test
              Start batman daemon on interface "eth1" and on alias interface "wlan0:test"

       batmand -o 2000 -a 192.168.100.1/32 -a 10.0.0.0/24 eth1
              Start  batman  daemon  on  interface  "eth1"  with originator interval of 2000 ms while announcing
              192.168.100.1 and 10.0.0.0/24.

       batmand -s 192.168.1.1 -d 1 eth1
              Start batman daemon on interface "eth1", sending topology  information  to  192.168.1.1  and  with
              debug level 1 (does not fork into the background).

       batmand eth1 && batmand -c -d 1 -b
              Start  batman  daemon  on interface "eth1". Connect in client mode to get the debug level 1 output
              once (batch mode).

       batmand -g 2000kbit/500kbit eth1 && batmand -c -r 1
              Start batman daemon on interface "eth1" as internet gateway. Connect in client mode to disable the
              internet gateway and enable internet search mode.
