List effective firewall rules for VMs with NSX-T

The distributed firewall enforces firewall rules on each vNic of each VM. To find which rules are effectively enforced on a VM the following commands can be used on the transport node (hypervisor) where the virtual machine is running.

For ESXi

To access the list of firewall rules we first need to find the name of the dvfilter used on the VM's network adapter. Use the following command to access the full list:



Set NSX-T web UI and CLI timeout

Configure CLI timeout

The NSX-T Manager appliance shell is configured with a default timeout of 600 seconds . This timeout can be changed from the NSX Manager Command Line Interface. Access the NSX Manager CLI through the console or through SSH. With the following command you can retrieve the current setting of the CLI timeout:

get cli-timeout

To configure the timeout use the following command:

set cli-timeout <seconds>

Setting a timeout for User Interaction in vRealize Orchestrator

When using a User Interaction element in your workflow you might want to have it timeout after a certain amount of time. A user interaction accepts an input parameter of the Date-type that contains the date and time when the user interaction should timeout if it is not answered.
In the image below you see a workflow that contains a Scriptable task used to create the date_time variable to be used in the user interaction.

Set timeout to 0 for VMware products

The vSphere Client and vSphere Web Client in the vCenter Appliance both have a timeout of 120 minutes. vRealize Automation has a timeout of 30 minutes. When I am teaching VMware classes the client always has just timed out when I want to demonstrate something to my students and I then have to re-login. So therefor I always configure the timeout to 0 (no timeout) at the start of each class. It is documented here how to do that:

New web site for VMware ports overview launched

VMware has released a new web site that conveniently contains all used ports per product. Not all products are covered yet but let's hope that's a matter of time. Here is an example of ports for NSX for vSphere with a filter that shows the ports used when ESXi is the source. This allows you to conveniently find the used ports per component.

VMware Horizon Manual Floating pool with two users in AD group for computer management

A customer asked if it is possible to allow AD users to manage an existing virtual machine through an HTML connection. In this short video I am showing this setup with two VMs (each in their own pool) that can be accessed by two individual users that are members of an AD Group. To accomplish this you would have to create a Manual Floating pool with 1 VM per pool that can be accessed by multiple users (not simultaneously). Use a manual pool to make sure VMs are not deleted or otherwise managed by Horizon.

vSAN: No witness! No problem?

When you study how vSAN works then you will read about how objects are backed by one or more components. This is dependent on the fault tolerance level and what you would also read is that a tie-breaker witness will be created. This is to make sure that when a network partition occurs, servers in a network partition can decide whether or not they together hold more than 50% of the necessary components and/or witnesses.
