NAME"gvpe" - GNU Virtual Private Ethernet Daemon
SYNOPSISgvpe [-cDlL] [--config=DIR] [--no-detach] [-l=LEVEL]] [--kill[=SIGNAL]] [--mlock] [--help] [--version] NODENAME [option...]
DESCRIPTIONSee 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: [I<nodename>.]var=value 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 this: gvpe -D -l info laptop \ http-proxy-host=10.0.0.18 http-proxy-port=3128 \ laptop.enable-tcp=yes
OPTIONS-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). --help 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 files/partitions. --version Output version information and exit.
SIGNALSHUP 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. TERM Closes/resets all connections and exits. USR1 Dump current network status into the syslog (at loglevel notice, so make sure your loglevel allows this).
FILES/etc/gvpe/gvpe.conf The configuration file for gvpe. /etc/gvpe/if-up Script which is executed as soon as the virtual network device has been allocated. Purpose is to further configure that device. /etc/gvpe/node-up Script which is executed whenever a node connects to this node. This can be used for example to run nsupdate. /etc/gvpe/node-down Script which is executed whenever a connection to another node is lost. for example to run nsupdate. /etc/gvpe/pubkey/* The directory containing the public keys for every node, one file per node with the name of the node. /etc/gvpe/hostkey The file containing the private key of the node GVPE runs on. Unlike all the other files in the /etc/gvpe directory, this file usually differes for each node that GVPE runs on. /var/run/gvpe.pid The PID of the currently running gvpe is stored in this file.
BUGSThe cryptography in gvpe has not been thoroughly checked by many people yet. Use it at your own risk! If you find any bugs, report them to @schmorp.de.
