Quick Guide to PowerShell v2 Remoting with PSSession

  • 아티클

There are excellent, detailed references to all the powerful remoting features in PowerShell v2, including:

Both of these are far more detailed and involved than is necessary to get up and running with PowerShell PSSession commands. And that's what I really like to use, since I'm predominantly an interactive PowerShell user. So, here's the basics to use PowerShell from your desktop to connect to a server (or other workstation) and run commands on that server or workstation. (note: this assumes a domain environment)

First, make sure PowerShell Remoting is enabled on the target server or workstation. For this one command, you'll need to open a Remote Desktop session on the target server or workstation, and open a PowerShell window As Administrator. 

    PSH> Enable-PSRemoting -force

That's it. The Enable-PSRemoting command needs to be run once only on a computer to enable it to receive commands.

Now, the basic steps for interactive PSSessions are:

  • Create a session (New-PSSession)
  • Use the session (Enter-PSSession)
  • Leave the session (Exit-PSSession or simply Exit)
  • Close the session (Remove-PSSession)

To create a new session on machine "srv1":

    PSH> $srv1 = New-PSSession srv1

Then, to actually use the session:

    PSH> Enter-PSSession $srv1
    [SRV1]: PS C:\Users\Charlie\Documents>
**
**And that's it - you now have an open PowerShell command window on the remote computer, srv1. Any commands you enter there will be processed on the remote computer. When you want to return to the local computer, simply type exit.
**
**To run a script or command against a remote computer, you can also use Invoke-Command. So, using our session from above, I can even run a CMD command:

PSH> Invoke-Command -session $srv1 -script {cmd /c dir c:\ }
