Windows Server FTP

Install FTP Server on Windows Server

Windows Server has IIS build in, which also offers an FTP server option. The File Transfer Protocol (FTP) is still a very popular protocol that allows users to simply upload and download files. Of course today you have more modern options, however, it is still very often used and a lot of legacy applications still support it. In this blog post, I wanna quickly go rough how you can install the FTP Server on Windows Server. I do this on a brand new Windows Server 2019 operating system, however, it didn’t really change since early Windows Server versions.

Install FTP Server Feature on Windows Server

Install FTP on Windows Server using PowerShell

First, you will need to install the FTP feature. I usually simply do that using PowerShell to install the FTP Server feature in Windows Server. You can also do that using the Server Manager. However, if you want to use PowerShell, you can use the following command:

 
Install-WindowsFeature Web-Ftp-Server -IncludeAllSubFeature -IncludeManagementTools -Verbose


VM Network Adapter

PowerShell One-liner to list IP Addresses of Hyper-V Virtual Machines

Here a very quick PowerShell command to list all the Virtual Network Adapters, including IP Addresses of Virtual Machines running on a Hyper-V Host.

 
Get-VM -ComputerName "Hyperv01" | Get-VMNetworkAdapter

This will give you a list of all Virtual Machines running on Hyper-V Server called “HyperV01”



sysprep.exe vm mode

Windows Sysprep for Virtual Machines

For using the same system image for different virtual machines or physical computer, Microsoft created a tool called sysprep.exe. This blog post covers Most people should be already familiar with that tool. If not here is the description:

Sysprep prepares a Windows installation (Windows client and Windows Server) for imaging, allowing you to capture a customized installation. Sysprep removes PC-specific information from a Windows installation, “generalizing” the installation so it can be reused on different PCs. With Sysprep you can configre the PC to boot to audit mode, where you can make additional changes or updates to your image. Or, you can configure Windows to boot to the Out-of-Box Experience (OOBE).

This is great so you can sysprep a virtual machine copy the VHD or VHDX file and use it for the first boot of different VMs. In Windows Server 2012 and Windows 8, Microsoft added an addition to sysprep called the mode switch “/mode:vm”. The mode:vm switch allows you to identify the Windows as a Virtual Machine and sysprep.exe will generalize a Virtual Hard Disk (VHD or VHDX) so that you can deploy the VHD as a VHD on the same Virtual Machine (VM) or hypervisor. You must deploy the VHD on a Virtual Machine (VM) or hypervisor with the same hardware profile. For example, if you created VHD in Microsoft Hyper-V, you can only deploy your VHD to Microsoft Hyper-V VMs with a matching hardware profile, and you can only run VM mode from inside a VM.

This will boost the performance and time for the virtual machine for the first startup and installation. This also work of course with virtual machines running on other hypervisors such as VMware or Xen.

Run the following command inside the Virtual Machine (You find sysprep.exe in the  C:\Windows\System32\Sysprep folder):

 
sysprep.exe /oobe /generalize /shutdown /mode:vm

Now you can copy the VHD or VHDX file from that virtual machine and use it for other VMs. Also check out my post about automating VM creation using an unattend.xml file.

Hyper-V VM Switch

Change Hyper-V VM Switch of Virtual Machines using PowerShell

This is one of the first post of a short blog series with some simple PowerShell scripts and oneliners for Hyper-V. One this is how you can connect a Virtual Network Adapter of a Hyper-V Virtual Machine to another Virtual Switch.

This is very simple, with this command you can see all the Network Adapters of the Virtual Machine and to which Switch they are connected:

 
Get-VM "VM01" | Get-VMNetworkAdapter

With this command you can connect it to another Switch:

 
Get-VM "VM01" | Get-VMNetworkAdapter | Connect-VMNetworkAdapter -SwitchName "NewSwitch"

Now of course you can also do this for all Virtual Machines running on a Hyper-V host:

 
Get-VM | Get-VMNetworkAdapter
 
Get-VM | Get-VMNetworkAdapter | Connect-VMNetworkAdapter -SwitchName "NewSwitch"
 
Get-VM | Get-VMNetworkAdapter


Powershell

Move multipe Hyper-V Virtual Machines with Live Storage Migration via Windows PowerShell

Well I was working in on a Private Cloud Deployment where we had some temporary storage for our Hyper-V Virtual Machines and after we got the right storage ready, which was btw a Windows Server Scale-Out File Server Cluster running with Storage Spaces and DataON JBOD chassis, we had to migrate the storage of all virtual machines running on our Hyper-V hosts. Since Windows Server 2012 offers Live Storage Migration which allows us to move the Virtual Machine to a different storage location without downtime we would use that. But if you have to move around 20 virtual machines you think twice if you want to move that via the Hyper-V Manager GUI or Windows PowerShell.

Here is a pretty simple PowerShell foreach loop which moves the storage of all virtual machines running on the Hyper-V host.

 
#New Storage Location
$StoragePath = "\\SMB01\VMs01\"
#VMs which will be migrated Get-VM will migrate all VMs
$VMs = Get-VM
 
Foreach ($VM in $VMs) {
$VMStorage = $StoragePath + $VM.Name
Write-Host "Moving VM:" $VM.name "to" $VMStorage
Move-VMStorage -VMName $VM.name -DestinationStoragePath $VMStorage
}


CDN Consistent Device Naming

Cisco UCS supports Consistent Device Naming (CDN)

Yesterday I posted about Cisco UCS supporting RDMA (SMB Direct) with firmware version 2.2(4b)B. Walter Dey, former Cisco Distinguished Engineer at Cisco informed me not only about the RDMA feature he also showed me that Cisco UCS now supports Consistent Device Naming which was introduced with Windows Server 2012. Consistent Device Naming (CDN) allows Ethernet interfaces to be named in a consistent manner. This makes Ethernet interface names more persistent when adapter or other configuration changes are made. To use CDN in Cisco UCS you need to run firmware version 2.2(4b)B. This will help to make it a lot easier to identify network interfaces used with Windows Server 2012 R2 and Hyper-V.
