Therefore the common diagnosis tools do not work as expected. To overcome these problems \fBbatctl\fP was created. At the moment the batctl contains \fBping\fP, \fBtraceroute\fP, \fBtcpdump\fP interfaces to the kernel module settings. +batctl offers a convenient way to configure the batman-adv kernel +module as well as displaying debug information such as originator +tables, translation tables and the debug log. In combination with a +bat-hosts file batctl allows the use of host names instead of MAC +addresses. .PP -batctl uses the /dev/batman-adv device provided by the B.A.T.M.A.N. advanced kernel module to inject custom icmp packets into the data flow. That's why ping and traceroute work almost like their IP based counterparts. Tcpdump analyzes the traffic and packet types used by B.A.T.M.A.N. advanced. +B.A.T.M.A.N. advanced operates on layer 2. Thus all hosts +participating in the virtual switched network are transparently +connected together for all protocols above layer 2. Therefore the +common diagnosis tools do not work as expected. To overcome these +problems batctl contains the commands \fBping\fP, \fBtraceroute\fP, +\fBtcpdump\fP which provide similar functionality to the normal +\fBping\fP(1), \fBtraceroute\fP(1), \fBtcpdump\fP(1) commands, but +modified to layer 2 behaviour or using the B.A.T.M.A.N. advanced +protocol. .PP -Furthermore batctl offers an convenient way to configure the batman-adv kernel module as well as displaying debug information such as originator tables, translation tables and debug log.

Level 0 disables +all logging. Level 1 enables messages related to routing / flooding / +broadcasting. Level 2 enables messages related to route or hna added / +changed / deleted. Level 3 enables all messages. The messages are sent +to the kernel log. Use \fBdmesg\fP(1) to see them. .br -.IP "\fBlog|l\fP " -Once started batctl will continuously read the log produced by the kernel module (the amount of log message can be influenced by modifying the log level).

The "-c" option tells batctl how often it should ping the given host before it stops by itself. With "-i" and "-t" you can influence the default interval time between pings and the timeout time for replies respectively. +.IP "\fBping\fP|\fBp\fP [\fB-c \fP\fIcount\fP][\fB-i \fP\fIinterval\fP][\fB-t \fP\fItime\fP] \fIMAC_address\fP|\fIbat-host_name\fP" +Layer 2 ping of a MAC address or bat-host name. batctl will try to +find the bat-host name if the given parameter was not a MAC +address. The "-c" option tells batctl how man pings should be sent +before the program exits. Without the "-c" option batctl will continue +pinging without end. Use CTRL + C to stop it.

This database can be used to search for routing loops (default action), to trace OGMs of a host (use "-t" to specify the mac address or bat-host name) throughout the network or to display routing tables of the nodes (use "-r" to specify the mac address or bat-host name). You can name a specific sequence number or a range using the "-s" option to limit the output's range. Furthermore you can filter the output by specifying an originator (use "-o" to specify the mac address or bat-host name) to only see data connected to this originator. If "-n" was given batctl will not replace the mac addresses with bat-host names in the output. +.IP "\fBtcpdump\fP|\fBtd\fP [\fB-p \fP\fIfilter\fP][\fB-n\fP] \fIinterface ...\fP" +batctl will display all packets that are seen on the given +interface(s). The "-p" options allows the filtering of certain packet +types: 1 - batman ogm packets, 2 - batman icmp packets, 4 - unicast +packets, 8 - broadcast packets, 16 - vis packets, and 32 - none batman +packets. These numbers can be added to filter more than one packet +type, e.g. use "-p 3" to display batman ogm packets and batman icmp +packets only.

This database can then be +analyzed in a number of different ways. With "-l" the database can be +used to search for routing loops. Use "-t" to trace OGMs of a host +throughout the network. Use "-r" to display routing tables of the +nodes. The option "-s" can be used to limit the output to a range of +sequence numbers, between min and max, or to one specific sequence +number, min.
