* This is the netconf service. It's currently used only by netconf nodes that
|
|
* are run by ZeroTier itself. There is nothing to prevent you from running
|
|
* your own if you wanted to create your own networks outside our system.
|
|
*
|
|
* That being said, we'd like to charge for private networks to support
|
|
* ZeroTier One and future development efforts. So while this software is
|
|
* open source and we're not going to stop you from sidestepping this, we
|
|
* do ask -- honor system here -- that you pay for private networks if you
|
|
* are going to use them for any commercial purpose such as a business VPN
|
|
* alternative.
|
|
*
|
|
* This will at the moment only build on Linux and requires the mysql++
|
|
* library, which is available here:
|
|
*
|
|
* http://tangentsoft.net/mysql++/
|
|
*
|
|
* (Packages are available for CentOS via EPEL and for any Debian distro.)
|
|
*
|
|
* This program must be built and installed in the services.d subfolder of
|
|
* the ZeroTier One home folder of the node designated to act as a master
|
|
* for networks. Doing so will enable the NETWORK_CONFIG_REQUEST protocol
|
|
* verb.
