       gvpe - GNU Virtual Private Ethernet Daemon


       gvpe [-cDlL] [--config=DIR] [--no-detach] [-l=LEVEL]] [--kill[=SIGNAL]]
       [--mlock] [--help] [--version] NODENAME [option...]


       See the gvpe(5) man page for an introduction to the gvpe suite.

       This is the manual page for gvpe, the virtual private ethernet daemon.
       When started, gvpe will read it's configuration file to determine the
       network topology, and other configuration information, assuming the
       role of node NODENAME

       It will then create/connect to the tun/tap device and set up a socket
       for incoming connections. Then a if-up script will be executed to
       further configure the virtual network device. If that succeeds, it will
       detach from the controlling terminal and continue in the background,
       accepting and setting up connections to other gvpe daemons that are
       part of the same virtual private ethernet.

       The optional arguments after the node name have to be of the form:


       If the argument has a prefix of nodename.  (i.e. laptop.enable-dns=yes)
       then it will be parsed after all the config directives for that node,
       if not, it is parsed before the first node directive in the config
       file, and can be used to set global options or default variables.

       For example, to start gvpe in the foreground, with log-level info on
       the node laptop, with TCP enabled and HTTP-Proxy host and Port set, use

         gvpe -D -l info laptop \
              http-proxy-host= http-proxy-port=3128 \


       -c, --config=DIR
           Read configuration options from DIR

       -d, --l=LEVEL
           Set logging level to LEVEL (one of: noise, trace, debug, info,
           notice, warn, error, critical).

           Display short list of options.

       -D, --no-detach
           Don't fork and detach but stay in foreground and log messages to
           stderr in addition to syslog.

       -L, --mlock
           Lock gvpe into main memory. This will prevent sensitive data like
           shared private keys to be written to the system swap

           Output version information and exit.


       HUP Closes/resets all connections, resets the retry time and will start
           connecting again (it will NOT re-read the config file). This is
           useful e.g. in a /etc/ppp/if-up script.

           Closes/resets all connections and exits.

           Dump current network status into the syslog (at loglevel notice, so
           make sure your loglevel allows this).


           The configuration file for gvpe.

           Script which is executed as soon as the virtual network device has
           been allocated.  Purpose is to further configure that device.

           Script which is executed whenever a node connects to this node.
           This can be used for example to run nsupdate.

           Script which is executed whenever a connection to another node is
           lost.  for example to run nsupdate.

           The directory containing the public keys for every node, usually
           autogenerated by executing gvpectrl --generate-keys.

           The PID of the currently running gvpe is stored in this file.


       The cryptography in gvpe has not been thoroughly checked by many people
       yet. Use it at your own risk!

       And thanks to many others for their contributions to gvpe, especially
       the tincd authors, who inspired me to write this program (after
       scavenging their source code ;).
