Hello

I need to copy files over the network PSSession . ( Firewall / DMZ / Etc. )

I have a script where I copy from my local server ( server1) to the remote server ( server2 ), but I cant not make script that will copy from the remote server to my local by my session. From server2 to server1

Script is as below ...:-)

HELP : ....

-----------------------------------------------------
winrm s winrm/config/client '@{TrustedHosts="SERVER2"}'

    $Source = "D:\test\ok.log"
      
    $Destination = "D:\test\ok.log"
    
    $session = New-PSSession -ComputerName SERVER2

Set-StrictMode -Version Latest

## Get the source file, and then get its content
$sourcePath = (Resolve-Path $source).Path
$sourceBytes = [IO.File]::ReadAllBytes($sourcePath)
$streamChunks = @()

## Now break it into chunks to stream
Write-Progress -Activity "Sending $Source" -Status "Preparing file"
$streamSize = 1MB
for($position = 0; $position -lt $sourceBytes.Length;
    $position += $streamSize)
{
    $remaining = $sourceBytes.Length - $position
    $remaining = [Math]::Min($remaining, $streamSize)

    $nextChunk = New-Object byte[] $remaining
    [Array]::Copy($sourcebytes, $position, $nextChunk, 0, $remaining)
    $streamChunks += ,$nextChunk
}

$remoteScript = {
    param($destination, $length)

    ## Convert the destination path to a full filesytem path (to support
    ## relative paths)
    $Destination = $executionContext.SessionState.`
        Path.GetUnresolvedProviderPathFromPSPath($Destination)

    ## Create a new array to hold the file content
    $destBytes = New-Object byte[] $length
    $position = 0

    ## Go through the input, and fill in the new array of file content
    foreach($chunk in $input)
    {
        Write-Progress -Activity "Writing $Destination" `
            -Status "Sending file" `
            -PercentComplete ($position / $length * 100)

        [GC]::Collect()
        [Array]::Copy($chunk, 0, $destBytes, $position, $chunk.Length)
        $position += $chunk.Length
    }

    ## Write the content to the new file
    [IO.File]::WriteAllBytes($destination, $destBytes)

    ## Show the result
    Get-Item $destination
    [GC]::Collect()
}

## Stream the chunks into the remote script
$streamChunks | Invoke-Command -Session $session $remoteScript `
    -ArgumentList $destination,$sourceBytes.Length

    Remove-PSSession -Session $session

Is there some reson you don't just use a copy comand?

You fail to expalini what your error is.

Hi Soren,

sounds to me as if you are experiencing the Second Hop Issue. In order to work around this, add this parameter to your New-PSSession call:

-Authentication Credssp

To read up on CredSSP (and figure out how to configure your systems to accept it), try Get-Help Enable-WSManCredSSP -Detailed.

jrv has a point about using Copy-Item though. Why not use it?

Cheers,
Fred

I are not allow by firewall, I im allowed only through https powershell ( Firewall / DMZ / Etc. )

But have will the script look,  if i need to copy from From server2 to server1.

?????????????

My script copy from server1 to server2 and working, but I need server2 to server1.

Right, I might have wanted to read the header.

Anyway, open a Remote Session with CredSSP Authentication on the remote system, and run the same script you are running locally on the destination system (opening a second hop remote session back on your local system).

Fred

Hi Soren,

so ... what is keeping you from transfering the script itself to the remote session (which you opened with CredSSP Authentication) and run it from there?

 

Or for that matter, why not do this even simpler:

Just run a scriptblock on the remote server that returns the bytes of the file you want? Then compile them back to file locally ...

Cheers,
Fred

Okidoki, i will try make it to run from the server2. But the best solution, will be to run from server2 to server1, Is a part a lot there are happing on server2.

You still havent; told us what the error is.

I knew from your firet post that you ad connectivity so that was not the issue.   Either you are gettiing an error or the code is hanging.  Please explain.

Do you know that BITS cando this very easily and canbe easily triggered to move a file.
