Check Point - SecurePlatform (SPLAT) - NTP Configuration

Syntax:

ntp <MD5_secret> <interval> <server1> [<server2> <server3>]
 
ntp -n <interval> <server1> [<server2> [<server3>]] (when working w/o MD5 secret)

 

Example:

For example, NTP-Server1: 10.100.100.21 & NTP-Server2: 10.100.100.22

• Enter "ntp" command with new NTP server IPs as follows.

[Expert@SPLAT]# ntp -n 300 10.100.100.21 10.100.100.22
[Expert@SPLAT]#

• The NTP configuration can be found in "/etc/sysconfig/ntp".

[Expert@SPLAT]# cat /etc/sysconfig/ntp
SERVER1=10.100.100.21
SERVER2=10.100.100.22
INTERVAL=300
MD5_SECRET=
USE_NTP=true
[Expert@SPLAT]#

• Execute command "chkconfig ntp on" for the new NTP configuration to survive reboot.

[Expert@SPLAT]# chkconfig ntp on
[Expert@SPLAT]#

• Execute command "ntpstat" to verify NTP status.

[Expert@SPLAT]# ntpstat
ntp is running
[Expert@SPLAT]#
[Expert@SPLAT]#
[Expert@SPLAT]# grep ntp /var/log/messages
