Description Miroslav Lichvar 2015-02-10 08:28:19 EST

+++ This bug was initially created as a clone of Bug #1166596 +++

Description of problem:
When ntpd is configured with a restrict directive using the limited option, disabling the monitoring facility with "disable monitor" will have no effect.
ntpd should print a warning to syslog when that happens to avoid unknowingly allowing the monlist amplification attack (CVE-2013-5211).

Version-Release number of selected component (if applicable):
4.2.6p5-1.el6

How reproducible:
always

Steps to Reproduce:
1. add "limited" to the default restrict lines in /etc/ntp.conf
2. add "disable monitor" to /etc/ntp.conf
3. start ntpd

Actual results:
no warning in syslog, that monitor couldn't be disabled

Expected results:
warning in syslog
