How to Fix | ntpq: command not found error
Error
bash: ntpq: command not found
The ntpq utility program is used to monitor NTP daemon ntpd operations and determine performance. The program can be run either in interactive mode or controlled using command line arguments.
Note
The ntp daemon is no longer available in RHEL 8. In RHEL 8, the NTP protocol is implemented only by the chronyd daemon, provided by the chrony package. The ntp daemon is available up to RHEL 7.
Causes
Typically this error return when ntp is not available or installed in the server. The ntpstat command will report the synchronization state of the NTP daemon running on the local machine. If the local system is found to be synchronized to a reference time source, ntpstat will report the approximate time accuracy. The “Name or service not known” error will be seen if the system cannot resolve “the server / system” for the ntpq command.
Solution
First we can check whether the ntp is enabled or installed in the server by typing below command.
[char@localhost ~]$ ntpq -p
bash: ntpq: command not found...
If above command return error. Please install ntp by using below commands.
[char@localhost ~]$ sudo yum install ntp
Restart ntp service after successful installation.
[char@localhost ~]$ systemctl restart ntpd
Check ntp service by typing below command.
[char@localhost ~]$ ntpq -p
