How can I get the name of a remote computer? Either on a PSSession or Invoke-Command session.

Invoke-Command -comp name -script {$env:computername}

You can't script a PSSession like that.  A PSSession is interactive.  This is why we have Invoke-Command, which will run a script on the remote machine in the context of that machine.  Therefore, your script should be:

Invoke-Command -Scr { $env:computername } -cn london

I'll say it again:  You can't script a PSSession.  Once you are in the session, the script loses scope.

But if I'm using a PSSession

$computers | % { Enter-PSSession -ComputerName $_ -Credential $credential; $env:computername; Exit-PSSession }

I allways get the local computer name.

Are you understand what are you doing?

$computers | % { Invoke-Command -comp $_ -script {$env:computername} -Credential $credential }

And what if I'm running some script inside a PSSession? How can I know the computer name?

This is a full script,the script return $env:computername from remote pc and no need to enter pssession.

I know I don't need to enter a pssession to get the computer name. But what if I'm already on a pssession?

Enter-PSSession ...
...
<get computer name>
...
Exit-PSSession

You should type manual command if you use Enter-PSSession.If you want to automate this,use the Invoke-Command with or without New-PsSession.

I'm sorry Kazun, but it either is possible or not. If I'm saying that I'm already on a pssession, Invoke-Command is no answer.

My script does several things inside a Enter-PSSession/Exit-PSSession and, at some point needs to know the computer name.

You can't use pssession in a loop.

Hi,

May be we can able to get a remote computer name  without Entering PSSession. But need to add some more scripts to get remote computer.

1. Need to check which remote machine is bind to your local machine with port 5985/5986 ,filter out the foreign address/IP of remote computer.

2. Then we can get the hostname form that IP address.  

*******************************************************************************************************************

1. Get-NetTCPConnection | Where-Object { $_.RemotePort -eq "5985"} | select RemoteAddress -Unique | fw > c:\temp.txt

2. Get-Content C:\temp.txt | where {$_-ne""}| foreach {$_.TrimEnd()} | Out-File c:\IP.txt

3. $IP=Get-Content C:\IP.txt

4. [System.Net.Dns]::GetHostEntry($IP)

I think I found the problem (it was between my chair and my keyboard).

My test script was something like:

Enter-PSSession -ComputerName 'london' -Credential $credential; $env:computername; Exit-PSSession

If I'm running from the LISBON machine, the result is LISBON not LONDON.

What am I doing wrong here?
