See the \fIgvpe\fR\|(5) manpage for an introduction to the gvpe suite. |

|
|
This is the manual page for gvpe, the virtual private ethernet daemon. |
| 145 |
|
|
When started, \f(CW\*(C`gvpe\*(C'\fR will read it's configuration file to determine the |
| 146 |
|
|
network topology, and other configuration information, assuming the role |
| 147 |
|
|
of node \fI\s-1NODENAME\s0\fR. It will then connect to the tun/tap device and set |
| 148 |
|
|
up a socket for incoming connections. Then a script will be executed to |
| 149 |
|
|
further configure the virtual device. If that succeeds, it will detach |
| 150 |
|
|
from the controlling terminal and continue in the background, accepting |
| 151 |
|
|
and setting up connections to other gvpe daemons that are part of the |
| 152 |
|
|
virtual private ethernet. |
| 153 |
pcg |
1.9 |
.PP |
| 154 |
|
|
The optional arguments after the node name have to be of the form: |
| 155 |
|
|
.PP |
| 156 |
|
|
.Vb 1 |
| 157 |
|
|
\& [I<nodename>.]var=value |
| 158 |
|
|
.Ve |
| 159 |
|
|
.PP |
| 160 |
|
|
If the argument has a prefix of \f(CW\*(C`nodename.\*(C'\fR |
| 161 |
|
|
(i.e. \f(CW\*(C`laptop.enable\-dns=yes\*(C'\fR) then it will be parsed after all the |
| 162 |
|
|
config directives for that node, if not, it is parsed befroe the first |
| 163 |
|
|
node directive in the config file, and can be used to set global options |
| 164 |
|
|
or default variables. |
| 165 |
|
|
.PP |
| 166 |
|
|
For example, to start \f(CW\*(C`gvpe\*(C'\fR in the foreground, with log-level \f(CW\*(C`info\*(C'\fR on |
| 167 |
|
|
the node \f(CW\*(C`laptop\*(C'\fR, with \s-1TCP\s0 enabled and HTTP-Proxy host and Port set, use |
| 168 |
