RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Ravindra Patil 2019-07-16 15:16:40 UTC
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; 


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):

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

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.
