Normally a Syslog Daemon listens on port 514 for UDP Syslog messages. If you want to listen on a different port for Syslog messages, you can enter any port value from 1 though to 65535. If you change the port from 514, the device sending the Syslog message must also be able to support the alternate port number.
If you would like to stop Syslog Daemon from listening for UDP Syslog messages, simply uncheck the Listen for UDP Syslog messages checkbox. This version of Kiwi Syslog Daemon can only listen for messages on a single UDP port at once. Future versions will be able to listen to multiple UDP ports simultaneously.
Bind to Address:
By default, the UDP socket will listen for messages on all connected interfaces. If you want to limit the binding to a single specific interface, you can specify the IP address in the Bind to address field. Otherwise, leave this field blank. (If the Bind to address field is left blank, it will listen on all interfaces. This is the best option in most cases.)
For example, if you have two non routed interfaces on the computer, 192.168.1.1 and 192.168.2.1, then you can choose to bind to only the 192.168.1.1 interface. This will ignore any syslog messages sent to the other interface.
