Where in our case the VMnet8 is the one assigned by default to the “NAT” configuration of the VM network card
Restart the VMNETDHCP service net stop vmnetdhcp net start vmnetdhcp
Port Forwarding Configuration
Modify (with Notepad running in Administrator mode) the vmnetnat.conf file present in C:\ProgramData\VMware by inserting the following lines: <tcpPortSource> = <IPaddress VM>:<tcpPortDestination>
Example: 8889 = 192.168.233.10:3389
In this case, we follow an RDP session to the OS system hosting my VM using: 8889 I will access through RDS to my VM with IP 192.168.233.10
*To check the IP range to always use the vmnetdhcp.conf file and identify the correct network segment; In the case of my example the segment is 8 (VMnet8)
# Virtual ethernet segment 8
# Added at 11/10/21 23:49:40
subnet 192.168.233.0 netmask 255.255.255.0 {
range 192.168.233.128 192.168.233.254; # default allows up to 125 VM’s
Whenever we installed a new vCenter the activity always included integration with Active Directory and normally IWA (Integrated Windows Authentication) was used. Since vSphere 7.0 version this possibility has been deprecated so it is good to start with the integration of the vCenter with Active Directory via LDAP. In our case, we will use LDAPS which uses a certificate
For first the step we need to create the certificate:
Copy the certificate output with —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—–
Past on Notepad and save with .crt extension
Now we will go to configure the Identity Sources on vCenter:
Login as Single Sign-On Administrator to vCenter
Navigate to Menu > Administration > Single Sign-On > Configuration
In the Identity Provider tab, open Identity Sources
Click ADD
Select Active Directory over LDAP or OpenLDAP, depending on your directory type.
Fill out the remaining fields as follows: Identity Source Name: Label Base DN for users: The Distinguished Name (DN) of the starting point for directory server searches. Example: “DC=pollaio,DC=lan”. Base DN for groups: The Distinguished Name (DN) of the starting point for directory server searches. Domain name: Your domain name. Example: “pollaio.lan” Domain alias: Your NetBIOS name. Example: “pollaio.lan” Username: Domain user with at least browse privileges. Example: “pollaio\administrator”. Connect to: “ldaps://<DC FQDN>”.
Click Browse next to SSL Certificate
Select the .cer file created in before step
Now we are ready to login to the vCenter with domain user (remember to assign the correct permission to domain group or user group)
If you want check the correct use of SSL certificate on the authentication to Active Directory with LDAP connection check the websso.log:
VMware has had a product for a while now called VMware Skyline that provides proactive monitoring, analysis, and support for your VMware environment. It monitors your VMware installation and will notify you when issues arise.
Skyline Advisor will be available to customers and partners with active Production and Premier Support, VMware Success 360 and vRealize Cloud Universal subscriptions at no additional cost.

Deploy Skyline Collector and configure the connection to Cloud Services
Copy and paste the token on Skyline Connect and register it.
Add source Data to Skyline Advisor
After complete the step 5 and 6 (I suggest to enable the auto-upgrade), we can access to skyline collector to configure the connection to vCenter (or multiple vCenter)
With the release of VMware vSphere 7 Update 3, this also means there is a new version of vSAN as well. VMware vSAN has been trailblazing in the world of HCI for several years now and with over 30,000 customers and many releases behind it, the solution has certainly grown, matured, and become […]
One of the conveniences of administering VMware solutions is being able to use code to create scripts to perform repetitive tasks or automate processes
One of the vSphere Web Client features that can help those new to the PowerCli is the Capture Code, it basically allows you to list and save the Powercli commands of the actions you are doing with the vSphere Web Client.
To activate it just access the vSphere Web Client, from the Menu select Developer Center
Select Code Capture and enable it by placing the “Enable Code Capture” flag on the right (which turns green)
At this point, a space will appear in our frame where the commands will be listed with some operations, such as Clear and start another, Copy and Download
Where the Download option generates you the ps1 file with the Powercli commands of the recorded operations
To start and stop a recording session you can use the buttons:
Or the red button that appears at the top of the WebClient once “Enable Code Capture” is enabled
In an old post, I described how to send ESXi logs to Azure Log Analytics to ingest at Azure Sentinel, now I describe Step to Step how to send vCenter logs.
The first step is to do step by step this configuration:
Protocol and port depend on your infrastructure configuration (you need to enable communication from VCSA to Syslog Gateway Server on the select TCP/UDP port)
and enable send events (it is enabled by default, but a check is a good idea)
Now you can connect to the Syslog Gateway Server and check if the Syslog server received the logs from the VCSA Appliance
Use SSH to connect at the Syslog Gateway Server and use this command
cat /var/log/syslog | grep <fqdn vCenter> | more
in my situation
cat /var/log/syslog | grep vcenter | more
Configure the Log Analytics Agent, installed on Syslog Gateway Server to process the Facility Local0
Connect to Azure Portal and on Azure Log Analytics Service enable the correct facility (local0)
After 10/15 minutes the new configuration will be applied on Syslog Gateway Server (you can check the file /etc/rsyslog.d/95-omsagent.conf on Syslog Gateway)
Change the VMwareESXi function (It was created for ESXi Log check my old post) or create a query custom to parse the log on Azure Log Analytics
Finally, you can query the data on Azure Log Analytics
Syslog | where HostName contains “<FQDN vCenter>”
or optionally you can edit the function create for Ingest ESXi log (check my old POST) and insert the vCenter FQDN Name in the same position where there is the ESXi FQDN Name.
Currently, on Azure Sentinel there are no specific Workbooks for VMware, all queries are to be created
VMware a few days ago released a new Horizon Version. The new build 2106 (8.3) brings with it some very interesting features from some relating to the security of intellectual property to those related to the Teams collaboration tool, here is a list of those that I consider the most interesting:
Implementation of GPO for blocking the ability to take screenshots of VDI sessions from Windows and MAC Clients
Possibility in the instant clone to use the Microsoft Sysprep (this function slows down the deployment of an IC by performing a series of reboots)
Functionality for applications of run indefinitely
Possibility to use TrueSSO SAML authentication for non-Trust domains
Horizon Agent has support for Windows Server 2022 (Currently in Preview)
The Horizon Client for Linux has the optimization for Teams (as in some versions the functionality for the Windows client was present)
Cloud Burst support to extend your on-prem workload to the Cloud in case of a high load.
In the past, I’ve talked about how to customize the Horizon Web Client login page. Normally when you log in you are asked whether to continue with the Web Client or download the Windows client, if required we can omit this page.
To do this you need to change the following value:
enable.download=true
setting it as false
this parameter is found in the file portal-links-html-access.properties in the connection server folder C:\ProgramData\VMware\VDM\portal, if you have a connection server cluster you have to do the switch on all servers
Have you upgraded to at least horizon 7.13? From March 22nd (this is tomorrow as I am writing to you) versions prior to 7.13 will no longer be in support
