chain_hostnames(no);
flush_lines(0);
use_dns(no);
use_fqdn(no);
create_dirs(no);
keep_hostname(yes);
}
source s_network {
tcp(ip(“IPADDRESS“) port(PORTNUMBER) keep-alive(yes));
udp(ip(“IPADDRESS“) port(PORTNUMBER));
internal();
};
destination d_file {
file(“/var/log/syslog-ng/server.log“);
};
log {
source(s_network);
destination(d_file);
};
Step 4: Start Syslog-NG
