148     .IX Header "DESCRIPTION"
149     See the \fIgvpe\fR\|(5) manpage for an introduction to the gvpe suite.
150     .PP
151     This is the manual page for gvpe, the virtual private ethernet daemon.
152     When started, \f(CW\*(C`gvpe\*(C'\fR will read it's configuration file to determine the
153     network topology, and other configuration information, assuming the role
154 pcg 1.11 of node \fI\s-1NODENAME\s0\fR
155     .PP
156     It will then create/connect to the tun/tap device and set up a socket for
157     incoming connections. Then a \f(CW\*(C`if\-up\*(C'\fR script will be executed to further
158     configure the virtual network device. If that succeeds, it will detach
159 pcg 1.1 from the controlling terminal and continue in the background, accepting
160     and setting up connections to other gvpe daemons that are part of the
161 pcg 1.11 same virtual private ethernet.
162 pcg 1.9 .PP
163     The optional arguments after the node name have to be of the form:
164     .PP
165     .Vb 1
166     \& [I<nodename>.]var=value
167     .Ve
168     .PP
169     If the argument has a prefix of \f(CW\*(C`nodename.\*(C'\fR
170     (i.e. \f(CW\*(C`laptop.enable\-dns=yes\*(C'\fR) then it will be parsed after all the
171 pcg 1.11 config directives for that node, if not, it is parsed before the first
172 pcg 1.9 node directive in the config file, and can be used to set global options
173     or default variables.
174     .PP
175     For example, to start \f(CW\*(C`gvpe\*(C'\fR in the foreground, with log-level \f(CW\*(C`info\*(C'\fR on
176     the node \f(CW\*(C`laptop\*(C'\fR, with \s-1TCP\s0 enabled and HTTP-Proxy host and Port set, use
177     this:

181     \& http\-proxy\-host=10.0.0.18 http\-proxy\-port=3128 \e

192     warn, error, critical).

201     .IX Item "-L, --mlock"
202     Lock \f(CW\*(C`gvpe\*(C'\fR into main memory. This will prevent sensitive data like

211     Closes/resets all connections, resets the retry time and will start connecting
212     again (it will \s-1NOT\s0 re-read the config file). This is useful e.g. in a
