       fastd - Fast and	Secure Tunnelling Daemon

       fastd OPTION...

       fastd  is a very	small VPN daemon which tunnels IP packets and Ethernet
       frames over UDP.	It supports various modern encryption and  authentica-
       tion schemes and	can be used in many different network topologies (1:1,
       1:n, meshed).

       --help, -h
	      Shows a help text.

       --version, -v
	      Shows the	fastd version.

       --daemon, -d
	      Runs fastd in the	background.

       --pid-file <filename>
	      Writes fastd's PID to the	specified file.

       --status-socket <socket>
	      Configure	a socket to get	fastd's	status.

       --config, -c <filename>
	      Loads a config file. - can be specified to read  a  config  file
	      from stdin. More than one	config file can	be loaded.

       --config-peer <filename>
	      Loads a config file for a	single peer. The filename will be used
	      as the peer name.

       --config-peer-dir <dir>
	      Loads all	files from a directory	as  peer  configs.  On	SIGHUP
	      fastd will reload	peer directories.

       --user <user>
	      Sets the user to run fastd as.

       --group <group>
	      Sets the group to	run fastd as.

       --log-level error|warn|info|verbose|debug|debug2
	      Sets the stderr log level; default is info if no alternative log
	      destination is configured.

       --syslog-level error|warn|info|verbose|debug|debug2
	      Sets the log level for syslog output; default is not to use sys-

       --syslog-ident <ident>
	      Sets the syslog identification; default is fastd.

	      Hides IP addresses in log	output.

	      Hides MAC	addresses in log output.

       --mode, -m tap|multitap|tun
	      Sets the mode of the interface; default is TAP mode.

       --interface, -i <name>
	      Sets the name of the TUN/TAP interface to	use. If	not specified,
	      default names specified by the system will be used.

       --mtu, -M <mtu>
	      Sets the MTU; must be at least 576.

       --bind, -b <address>[:<port>]
	      Sets the bind address. Address can be an IPv4 address or an IPv6
	      address,	or  the	 keyword  any.	IPv6  addresses	must be	put in
	      square brackets.

	      By default fastd will to bind to a random	port for both IPv4 and
	      IPv6. It is currently not	possible to specify an IPv6 link-local
	      address on the command line.

       --protocol, -p <protocol>
	      Sets the handshake protocol. Currently the only protocol	avail-
	      able  is	ec25519-fhmqvc,	which provides a secure	authentication
	      of peers based on	public/secret keys.

       --method	<method>
	      Sets the encryption method.

	      Enables forwarding of packets between peers; read	the full docu-
	      mentation	before use!

       --on-pre-up <command>
	      Sets a shell command to execute before interface creation.

       --on-up <command>
	      Sets a shell command to execute after interface creation.

       --on-down <command>
	      Sets a shell command to execute before interface destruction.

       --on-post-down <command>
	      Sets a shell command to execute after interface destruction.

       --on-connect <command>
	      Sets  a shell command to execute when a handshake	is sent	to es-
	      tablish a	new connection.

       --on-establish <command>

       --on-disestablish <command>
	      Sets a shell command to execute when a connection	is lost.

       --on-verify <command>
	      Sets a shell command to execute to check a connection attempt by
	      an unknown peer.

	      Checks the configuration and exits.

	      Generates	a new keypair.

	      Shows the	public key corresponding to the	configured secret.

	      Suppresses output	of  explaining	text  in  the  --show-key  and
	      --generate-key commands.

       The  full  documentation	 for  fastd  is	 maintained  in	 the  Wiki  at
