Distributed Systems Administration Utilities User's Guide

a. If configuring the system to forward its syslogs to the consolidation server, replace
the <%UDP_LOOPBACK_SOURCE%> token with:
source s_syslog_udp { udp(port(514)); };
Replace the <%UDP_LOOPBACK_LOG%> token with:
log { source(s_syslog_udp); destination(d_syslog_type); };
where type is either tcp or udp depending on the desired log transport. This causes
syslog-ng to read the local syslogd’s UDP messages and send them to the log
consolidation server. If you do not want to consolidate the local syslogs of this system,
delete the <%UDP_LOOPBACK_SOURCE%> and <%UDP_LOOPBACK_LOG%> tokens.
b. Replace all the <%TYPE%> tokens with either tcp or udp depending on the desired log
transport.
c. Find the line
“destination d_syslog_<%TYPE%>{<%TYPE%>(“<%IP%>” port(<%PORT%>)); };”
If using the UDP protocol, replace <%IP%> with the IP address of the log consolidation
server and <%PORT%> with 514, the standard UDP port.
If using the TCP protocol with ssh port forwarding, replace <%IP%> with 127.0.0.1 and
<%PORT%> with the port chosen for ssh port forwarding. The same guidelines for
choosing a free syslog-ng TCP port apply to this port. For details, refer to “Configuring
a Log Consolidation Standalone Server with clog_wizard” (page 46).
Non-interactive secure shell authentication must be set up between this system and the
log consolidator (you can use the /opt/dsau/bin/csshsetup tool for the
configuration). For details, refer to “ssh Port Forwarding” (page 78).
If using the TCP protocol without ssh port forwarding, replace <%IP%> with the IP
address of the log consolidation server and <%PORT%> with TCP port chosen on the
log consolidator used for log consolidation.
d. Create the following symbolic link:
ln -sf /etc/syslog-ng.conf.client /etc/syslog-ng.conf
