I have some code that sits listening on a UDP port waiting to process syslog messages.
Just wondering how I can have syslog push messages (via a UDP socket) to that port?
That depends on the syslog software you're using. If you have syslog-ng, you would create a configuration file in the 'syslog-ng/conf.d' directory with the new destination and log statement. The following is from a blog post I wrote about setting up TLS tunnels. Just change the protocol, port, destination, etc.
destination d_tls {
tcp("your.logzilla.server" port(1999)
tls( ca_dir("/etc/syslog-ng/ssl/")) );
};
log {
source(s_src);
destination(d_tls);
};
