I have been trying to start a basic SYSLOG UDP input. But this FAILS to start because “address is already in use”.
First at port = 514, then I read in forum that only root can use this port or I must use firewall redirecting. For quick demo, I try change the port to a non-privileged range.
Secondly, I then try port = 8514. This also fails. Then I get frustrated and change to port 8515 and I get the same thing.
I also tried port 1514. Same thing. It is almost as if every port it anticipates I will try, becomes “address already in use”. IP address used = 0.0.0.0:8514.
Iptables off. Selinux is set to permissive. What else could I be doing wrong?
