Recieve syslog messages on UDP 514 and log them into syslog
My Asus router (RT-N18U) as a "Remote Log Server" option. This sends syslog messages to the UDP 514 port. Enabling the server portion of syslogd required System Integrity Protection (SIP) to be turned off, and a bunch of other shenanigans.
This script needs to be executed with sudo (bad), but it just works (good!)
