### A sample syslog-ng configuration file for a log collecting host
### 
### This sample is for a log collecting host by syslog-ng.
### A syslog-ng process configurated by this sample accepts all messages
### from a certain network. Any message from the network is preserved into
### a file for security infomation. Restricting messages to "authpriv" from
### the network is done on log sending hosts. (See the sample below)
### Any internal message of the syslog-ng process is preserved into its 
### dedicated file. And any "authpriv" internal message of the syslog-ng 
### process is also preserved into the security infomation file.
###
### Change "f_incoming" to suit your enviroment.
### If you use it as a configuration file for the sample cib.xml above,
### save it into "/etc/syslog-ng/syslog-ng-ext.conf".
