      On older nodes, the trick was to use rdate to sync the time with another computer. But most of the public time servers no longer accept requests using this protocol.

      So to get around this, I have set up the service on all of the IRLP servers, and created a DNS pool to balance the load across the servers.

      So if you have a time syncronization script that uses rdate (either within IRLP or outside of it), use the server:

      time.irlp.net
      or
      ntp.irlp.net

      to sync your time.

      This is important for older that redhat 9 nodes, and embedded IRLP nodes. NTP (the newer protocol) has been installed by default on all nodes since Fedora Core 3, including the latest CentOS systems.

      On embedded nodes the host name used in the script:

      /usr/sbin/set-time

      will have to be changed to use this new servers. Be sure to run a flash_sync to save the changes.

      The file should look like this when you are done:

      #!/bin/bash

      rdate -t 5 -s time.irlp.net
      hwclock --systohc
      date
