Login to ESXi with Domain User | VMware ESXi Active Directory Authentication

Configuring VMware ESXi for Active Directory (AD) authentication involves joining the ESXi host to the Active Directory domain and configuring user permissions accordingly. Here are the steps:

1. Access the ESXi Host:

  • Connect to the ESXi host using the vSphere Client or vSphere Web Client.

2. Configure DNS Settings:

  • Ensure that the DNS settings on the ESXi host are correctly configured, and it can resolve the Active Directory domain controller’s name. You can set the DNS configuration in the ESXi host under “Networking” > “TCP/IP Configuration.”

3. Join ESXi Host to Active Directory:

  • In the vSphere Client, navigate to the “Host” in the inventory and select the “Configure” tab.
  • Under the “System” section, select “Authentication Services.”
  • Click “Join Domain” or “Properties” depending on your ESXi version.
  • Enter the domain information, including the domain name, username, and password with the necessary permissions to join the domain.
  • Click “Join Domain” or “OK.”

Example:

  • Domain: example.com
  • Username: domain_admin
  • Password: ********

4. Verify Domain Join:

  • After joining the domain, you should see a success message. If not, check the credentials and network connectivity.

5. Configure Permission:

  • Go to the “Permissions” tab in the “Host” section.
  • Add the AD user account to the appropriate role (e.g., Administrator or a custom role).

Example (PowerCLI):

New-VIPermission -Principal "EXAMPLE\domain_user" -Role "Admin" -Entity $esxiHost

6. Test AD Authentication:

  • Log out of the vSphere Client and log in using an Active Directory account. Use the format “DOMAIN\username” or “username@domain.com” depending on your environment.

Example:

  • Server: esxi.example.com
  • Username: example\domain_user
  • Password: ********

7. Troubleshooting:

  • If authentication fails, check the ESXi logs for any error messages related to authentication or domain joining.
  • Ensure that time synchronization is correct between the ESXi host and the domain controller.
  • Verify that the Active Directory user account has the necessary permissions.

Note: Always refer to the official VMware documentation for your specific ESXi version for the most accurate and up-to-date information. The steps might slightly differ based on the ESXi version you are using.

Install and Configuration VMware vSphere Replication

Hello everyone , in this video I am going to install and configure vmware vsphere replication , by using this tools you can replicate virtual machines disks from one one datastore to another datastore. For example you can replicate your disks to disaster center datastore and if your server gets down you can bring up or restore your virtual machine in your disaster center in some seconds ,

Prerequisites:

Before you begin, make sure you have the following prerequisites in place:

  1. VMware Infrastructure: You should have a VMware vSphere environment set up with at least two vCenter Servers or ESXi hosts that you want to replicate VMs between.
  2. Network Connectivity: Ensure that there is proper network connectivity between the source and target vSphere environments. This includes firewalls, routers, and other networking components.
  3. vSphere Replication Appliance: Download the vSphere Replication appliance OVA file from the VMware website or portal.
  4. Licensing: Ensure that you have the necessary licensing for vSphere Replication. It’s typically included with VMware’s vSphere Essentials Plus and higher editions.

Installation and Configuration:

Follow these steps to install and configure VMware vSphere Replication:

  1. Deploy vSphere Replication Appliance:
    • Log in to the vCenter Server where you want to deploy the vSphere Replication Appliance.
    • From the vCenter Web Client, select “Hosts and Clusters.”
    • Right-click on a host or cluster and select “Deploy OVF Template.”
    • Browse to the location of the vSphere Replication Appliance OVA file and follow the deployment wizard, specifying network settings, deployment size, and other necessary configurations.
  2. Configure vSphere Replication Appliance:

Install and Config Cisco ASA on GNS3

Hello, today we will install GNS3 with you and then we will install CISCO ASA on it. I will also explain how we can connect to Cisco ASA with ASDM.

Let’s start.

Step 1: Obtain Cisco ASA Image

You’ll need a Cisco ASA image file to run it in GNS3. You can acquire this image from legal and legitimate sources, such as Cisco’s official website, or if you have a Cisco ASA device, you may be able to extract it. Make sure you have the proper licensing to use the image.

Step 2: Install GNS3

If you haven’t already, download and install GNS3 on your computer from the official website (https://www.gns3.com/). Follow the installation instructions for your specific operating system.

Step 3: GNS3 Initial Setup

  1. Launch GNS3 and complete the initial setup wizard. This typically includes configuring preferences like where to store your projects and images.
  2. Make sure you have the GNS3 VM (Virtual Machine) configured and running. You can download the GNS3 VM from the GNS3 website and follow the installation instructions provided there.

Step 4: Add Cisco ASA to GNS3

  1. In GNS3, go to “Edit” > “Preferences.”
  2. In the Preferences window, click on “QEMU VMs” on the left sidebar.
  3. Click the “New” button to add a new virtual machine.
  4. Provide a name for the virtual machine (e.g., “Cisco ASA”).
  5. In the “Type” dropdown menu, select “ASA” for Cisco ASA.
  6. In the “QEMU binary” section, browse and select the QEMU binary executable. This binary should be located in your GNS3 VM.
  7. Set the RAM and CPU settings based on your system resources and requirements.
  8. Click “Next” and follow the on-screen instructions to complete the virtual machine setup.

Step 5: Add ASA Image to GNS3

  1. In GNS3, go to “Edit” > “Preferences” again.
  2. In the Preferences window, click on “QEMU” on the left sidebar.
  3. Click the “QEMU VMs” tab.
  4. Select the “Cisco ASA” virtual machine you created earlier.
  5. In the “QEMU Options” section, click the “Browse” button next to “QEMU image” and select the Cisco ASA image file you obtained.

Step 6: Configure Cisco ASA in GNS3

  1. Drag and drop the Cisco ASA device from the GNS3 device list onto your GNS3 workspace.
  2. Right-click on the ASA device and choose “Start.”
  3. Right-click again and select “Console” to open the console window for the ASA.
  4. Configure the ASA as needed using the command-line interface (CLI). This includes setting up interfaces, IP addresses, access control policies, and any other configurations you require.
  5. Save your configurations to ensure they persist across sessions.

With these steps, you should have a Cisco ASA running in GNS3, ready for configuration and testing in your simulated network environment. Remember to follow proper licensing and usage guidelines when using Cisco ASA images.
