Configure ntpd To Run As ntp User
Medium Severity
ntp is a daemon which implements the Network Time Protocol (NTP). It is designed to synchronize system clocks across a variety of systems and use a source that is highly accurate. More information on NTP can be found at
http://www.ntp.org
. ntp can be configured to be a client and/or a server. To ensure that ntpd is running as ntp user, Add or edit the
OPTIONS
variable in
/etc/sysconfig/ntpd
to include ' -u ntp:ntp ':
OPTIONS="-u ntp:ntp"
This recommendation only applies if ntp is in use on the system.
