A standalone server might be launched using the {{Code|sugar-stats-server}} command from project sources. The easiest way is using the binary package [http://download.sugarlabs.org/packages/Server:/Factory/ sugar-stats-server]. The package contains these components:

* {{Code|sugar-stats-server}} command,

* {{Code|sugar-stats-server}} command,

* {{Code|/etc/init.d/sugar-stats}} daemon.

For stats transfering from clients, it is useful to use secure SSL connection. Server configuration needs to be tweaked (the [[Sugar_Server_Kit/sugar-client#Usage statistics|client]] should use the same certificate):

For stats transferring from clients, it is useful to use secure, SSL connections. The server configuration needs to be tweaked (and the [[Sugar_Server_Kit/sugar-client#Usage statistics|client]] should use the same certificate):

* {{Code|stats-keyfile}}, path to server's private key,

* {{Code|stats-keyfile}}, path to server's private key,

* {{Code|stats-certificate}}, path to server's certificate file.

* {{Code|stats-certificate}}, path to server's certificate file.

Server will authenticate clients using SSH keys generated on client side by Sugar Shell. To let server check client signatures, OpenSSH-5.6+ should be installed on server side. For less than 5.6 versions, authentication needs to be disabled using {{Code|trust-users}} parameter.
