It is necessary that I get Graylog-server to listen on port 514. I found a walkthrough at
https://www.reddit.com/r/graylog/comments/5qcjw0/using_authbind_to_run_graylog/ but it still will not allow me to setup an input on port 514. I receive an Operation not permitted error when it tries to start the input. Is there something missing from the link above that will allow me to use authbind to get Graylog working or another option that is not firewall related? Thanks in advance.
