Description of problem: In /etc/services, port 5666 shows the following confusing line: ###UNAUTHORIZED USE: Port 5666 used by SAIC NRPE############ The latest port assignment from IANA shows that port number 5666 is registered by Nagios for use; https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=5666 In other words, the line(s) should be something like in /etc/services : nrpe 5666/tcp # Nagios Remote Plugin Executor nrpe 5666/udp # Reserved for Nagios Remote Plugin Executor In Summary, the /etc/services file should reflect all of the current IANA port assignments. Can we get this fixed upstream and propagated to RHEL 7.x and 8.x? Version-Release number of selected component (if applicable): setup-2.12.2-1.el8.noarch.rpm How reproducible: - By default no entry for nrpe port 5666 in /etc/services Steps to Reproduce: 1. Check entry in /etc/services for port 5666 2. 3. Actual results: ###UNAUTHORIZED USE: Port 5666 used by SAIC NRPE############ Expected results: nrpe 5666/tcp # Nagios Remote Plugin Executor nrpe 5666/udp # Reserved for Nagios Remote Plugin Executor Additional info: Same has been the situation in RHEL7 and RHEL8.
