Repository : ssh://git@open-mesh.org/alfred On branch : master >--------------------------------------------------------------- commit 943fd999f664d1072136a88cd57c4ba15b4ad27c Author: Sven Eckelmann <sven(a)narfation.org> Date: Mon Nov 20 14:50:25 2017 +0100 alfred: Convert CHANGELOG to reStructuredText The current format of the file is not well defined. The reStructuredText format (as used by other batman-adv related files) has the benefit that it is similar easy to read and write. And it allows other tools to parse the content of the file and convert it in a sensible way to a different file format. Multiple git repository web-based management software also can directly render these files as properly formatted HTML output.

B.A.T.M.A.N. advanced operates on layer 2 and thus all -hosts participating in the virtual switch are completely transparent for all -protocols above layer 2. Therefore the common diagnosis tools do not work as -expected. To overcome these problems batctl was created. At the moment batctl -contains ping, traceroute, tcpdump and interfaces to the kernel module -settings. - - -How does it work ? -================== - -batctl uses the debugfs/batman_adv/bat0/socket 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 was -designed because B.A.T.M.A.N. advanced encapsulates all traffic within batman -packets, so that the normal tcpdump would not recognize the packets. - - -The bat-hosts file -================== - -This file is simliar to the /etc/hosts file. You can write one MAC address and -one host name per line. batctl will analyze the file to find the matching MAC -address to your provided host name. Host names are much easier to remember than -MAC addresses. ;) - - -batctl statistics -================= - -The batman-adv kernel module maintains a number of traffic counters which are exported -to user space. With batctl these counters can be easily retrieved. The output may vary -depending on which features have been compiled into the kernel module. For example, if -the distributed arp table (short: dat) wasn't selected as an option at compile time -its counters won't be shown. -Each module subsystem has its own counters which are indicated by their prefixes: - * mgmt - mesh protocol counters - * tt - translation table counters - * dat - distributed arp table counters -All counters without a prefix concern payload (pure user data) traffic. - -Usage: batctl statistics -

SPDX-License-Identifier: GPL-2.0 + +========================================================== +batctl - B.A.T.M.A.N. advanced control and management tool +========================================================== + +Introduction +============ + +Why do I need batctl ? B.A.T.M.A.N. advanced operates on layer 2 and thus all +hosts participating in the virtual switch are completely transparent for all +protocols above layer 2. Therefore the common diagnosis tools do not work as +expected. To overcome these problems batctl was created. At the moment batctl +contains ping, traceroute, tcpdump and interfaces to the kernel module +settings. + + +How does it work ? +================== + +batctl uses the debugfs/batman_adv/bat0/socket 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 was +designed because B.A.T.M.A.N. advanced encapsulates all traffic within batman +packets, so that the normal tcpdump would not recognize the packets. + + +The bat-hosts file +================== + +This file is similar to the /etc/hosts file. You can write one MAC address and +one host name per line. batctl will analyze the file to find the matching MAC +address to your provided host name. Host names are much easier to remember than +MAC addresses. ;) + + +batctl statistics +================= + +The batman-adv kernel module maintains a number of traffic counters which are exported +to user space. With batctl these counters can be easily retrieved. The output may vary +depending on which features have been compiled into the kernel module.

In this +example, only netns has been used, so there are no filesystem name +spaces. Hence the unix domain socket used by alfred needs to be given +a unique name per instance:: + + ($EMU1 alfred -m -i bat0 -u /var/run/emu1-alfred.soc) & + ($EMU2 alfred -m -i bat0 -u /var/run/emu2-alfred.soc) & + alfred -m -i bat0 & + + ($EMU1 batadv-vis -s -u /var/run/emu1-alfred.soc) & + ($EMU2 batadv-vis -s -u /var/run/emu2-alfred.soc) & + batadv-vis -s &
