The syslog-ng Premium Edition application is licensed on a per-host basis: the syslog-ng server accepts connections only from the number of individual hosts (also called log source hosts) specified in its license file.
A log source host is a host or network device (including syslog-ng clients and relays) that sends logs to the syslog-ng server. Log source hosts can be servers, routers, desktop computers, or other devices capable of sending syslog messages or running syslog-ng.
Buying a syslog-ng server license permits you to perform the following:
Install the syslog-ng application in server mode to a single host. This host acts as the central log server of the network.
Install the syslog-ng application in relay or client mode on host computers. The total number of hosts permitted to run syslog-ng in relay or client mode is limited by the syslog-ng server license. The client and relay hosts may use any operating system supported by syslog-ng. See Section 1.5, “Supported platforms” for details.
The syslog-ng Open Source Edition application is distributed under version 2 of the GNU General Public License. See Appendix 3, GNU General Public License for details.
