I have an interesting situation in which check_ntp_time is returning "NTP CRITICAL: No response from NTP server". This is odd because the NTP server is reachable from the host which is getting time from it successfully.<div>
<br></div><div>Here is an example of the plug-in failing to contact the server, and ntpdate running an updating time successfully.<br><div><br></div><div><div>[root@stripedmarlin ~]# /opt/app/nagios/nagios_plugins/current/libexec/check_ntp_time -t 30 -H <a href="http://ext-timekeeper.schoolspecialty.com">ext-timekeeper.schoolspecialty.com</a> -w 1 -c 2</div>
<div>NTP CRITICAL: No response from NTP server</div><div>[root@stripedmarlin ~]# ntpdate ext-timekeeper.schoolspecialty.com12 Jul 16:36:29 ntpdate[6233]: adjust time server 10.14.99.68 offset -0.003131 sec</div></div></div>
<div><br></div><div>Do you have any suggestions as to what may be going on? This is a RHEL 5.8 x86_64 VM.</div><div><br></div><div>Thank you,</div><div>Ken Edgar</div><div>Unix System Administrator - School Specialty, Inc.</div>
