VMware KB: Configuring Network Time Protocol (NTP) on ESX/ESXi hosts using the vSphere Client

Posted by jpluimers on 2016/09/16

Often it is better to configure more than just a single pool.ntp.org server in case the IP-address of the name gets cached too long and it becomes unresponsive during that period.

So it is better to configure multiple, choose from this list from [WayBackpool.ntp.org: How do I setup NTP to use the pool?.

0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
3.pool.ntp.org

Here are the steps for one server where you need to repeat the steps after entering pool.ntp.org:

To configure NTP on ESX/ESXi 4.1 and ESXi 5.x hosts using the vSphere Client:

  1. Connect to the ESX/ESXi host using the vSphere Client.
  2. Select a host in the inventory.
  3. Click the Configuration tab.
  4. Click Time Configuration.
  5. Click Properties.
  6. Click Options.
  7. Click NTP Settings.
  8. Click Add.
  9. Enter the NTP Server name. For example, pool.ntp.org.
    1. Note: When entering the multiple NTP Server names, use a comma (,) followed by a space ( ) between the entries.
  10. Click OK.
  11. Click the General tab.
  12. Click Start automatically under Startup Policy.
    1. Note: It is recommended to set the time manually prior to starting the service.
  13. Click Start and click OK.
  14. Click OK to exit.

Accessing the ESXi Direct Console User Interface DCUI via SSH – Wahl Network

Posted by jpluimers on 2014/11/05

I just learned (thanks Chris Wahl!) about the dcui command: often easier to configure basic parameters than the other UIs.

The DCUI is normally available from the console after you login, for instance to enable SSH.

This was new to me:

DCUI is available over SSH.

Even more embarrassing: duic has been actually there since ESXi 4.1 (:
