150 pcg 1.12 See the \fIgvpe\fR\|(5) man page for an introduction to the gvpe suite.
151 pcg 1.1 .PP
152     This is the manual page for gvpe, the virtual private ethernet daemon.
153     When started, \f(CW\*(C`gvpe\*(C'\fR will read it's configuration file to determine the
154     network topology, and other configuration information, assuming the role
155 pcg 1.11 of node \fI\s-1NODENAME\s0\fR
156     .PP
157     It will then create/connect to the tun/tap device and set up a socket for
158     incoming connections. Then a \f(CW\*(C`if\-up\*(C'\fR script will be executed to further
159     configure the virtual network device. If that succeeds, it will detach
160 pcg 1.1 from the controlling terminal and continue in the background, accepting
161     and setting up connections to other gvpe daemons that are part of the
162 pcg 1.11 same virtual private ethernet.
163 pcg 1.9 .PP
164     The optional arguments after the node name have to be of the form:
165     .PP
166     .Vb 1
167     \& [I<nodename>.]var=value
168     .Ve
169     .PP
170     If the argument has a prefix of \f(CW\*(C`nodename.\*(C'\fR
171     (i.e. \f(CW\*(C`laptop.enable\-dns=yes\*(C'\fR) then it will be parsed after all the
172 pcg 1.11 config directives for that node, if not, it is parsed before the first
173 pcg 1.9 node directive in the config file, and can be used to set global options
174     or default variables.
175     .PP
176     For example, to start \f(CW\*(C`gvpe\*(C'\fR in the foreground, with log-level \f(CW\*(C`info\*(C'\fR on
177     the node \f(CW\*(C`laptop\*(C'\fR, with \s-1TCP\s0 enabled and HTTP-Proxy host and Port set, use
178     this:
179     .PP

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