See the \fIgvpe\fR\|(5) manpage for an introduction to the gvpe suite. |
| 143 |
.PP |
| 144 |
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. |

.IX Item "HUP" |
| 180 |
Closes/resets all connections, resets the retry time and will start connecting |
| 181 |
again (it will \s-1NOT\s0 re-read the config file). This is useful e.g. in a |
| 182 |
\&\f(CW\*(C`/etc/ppp/if\-up\*(C'\fR script. |
