  • Restart w32 time server, now DC should synchronize time with uk.pool.ntp.org time servers. If the DC is not synchronizing time with the external NTP server then check the event logs (Event Viewer System). Normally event id 47 which means it is unable to reach the external NTP server, check the firewall to make sure port 123 is open.
By providing dual network functionality in a single unit, the GPS NTP server is a cost-effective method of time synchronization for larger organizations. The server mounts in a 19-inch rack, making it easy to install alongside your existing IT hardware. The server maintains network security by sitting behind your firewall.

You can synchronize an event broker’s clock with a networked Network Time Protocol (NTP) server. This is especially helpful for event brokers that are using redundancy and/or Replication. For example, if your event brokers are synchronized with the same NTP server, message expiry times will be consistent across all of them.

The procedure for synchronizing with an NTP server differs for appliances and software event brokers.

Appliances

An appliance can be time synchronized using either the set up commands explained in Initial Set Up, or using the clock synchronization CLI commands shown below:

solace(configure)# clock
solace(configure/clock)# synchronization
solace(configure/clock/synchronization)# shutdown
solace(configure/clock/synchronization)# protocol ntp
solace(configure/clock/synchronization)# ntp-server <ip-addr>
solace(configure/clock/synchronization)# no shutdown

Where:

Sync Time With Ntp Server

ip-addr is the IP address or fully qualified domain name (FQDN) of a reachable NTP server.

Synchronize Time With Ntp Server

The no version of this command, no ntp-server, removes the NTP server information.

Sync Time With Ntp Server Centos 7

: If you need to reset the clock synchronization protocol to NTP, use the command solace(configure/clock/synchronization)# no protocol

Software Event Brokers

Synchronize Time With Ntp Server Settings

Software event broker clocks can be synchronized with one of the three methods shown in the following list.

: With the PubSub+ AWS AMI, clock synchronization is preconfigured to use AWS time servers. Use chronyd to change the clock server.

  1. In your hypervisor or cloud environment:
    Use DHCP to configure NTP. This requires no host configuration.
  2. For software event broker machine images:
    Set up NTP through the event broker host.
    To do so, perform the following steps:
    1. Log in to your event broker's host as the root user.
    2. Edit the /etc/ntp.conf file and enter the following configuration.
      tinker panic 0
      disable monitor
      restrict default ignore
      restrict 127.0.0.1
      restrict ::1
      server <server-ip>
      restrict <server-ip>
    3. Enable ntpd.
      4. systemctl enable ntpd
    4. Then reboot the event broker.
      5. reboot
    5. In the event broker host shell, enter the following command to check whether the NTPD status is working:
      systemctl status ntpd
      In the displayed output, to confirm ntpd is active, check for a line that looks like this:
      'Active: active (running)' portion.
    6. Once NTPD is confirmed active, wait several minutes and enter the following command to verify that the event broker is now in sync.
      Full range drivers for open baffle design. ntpstat
      In the displayed output, to confirm that the event broker is in sync, check the output for a line that looks like this:
      synchronised to NTP server (192.168.40.80) at stratum 3
  3. Use Cloud-Init:
    Set up NTP with the same configuration information provided in steps 2.2 and 2.3 above.
    Example:
    write_files:
    - path: /etc/ntp.conf
    permissions: 0600
    owner: root:root
    content: |
    tinker panic 0
    disable monitor
    restrict default ignore
    restrict 127.0.0.1
    restrict ::1
    server <server-ip>
    restrict <server-ip>
    runcmd:
    - systemctl enable ntpd
    - systemctl start ntpd
