Downloading/upload files from ftp with powershell from virtualbox

Question

Hello i'm trying to upload files to my virtual machine that run linux and ftp server. I have an exception in the code:

    Exception calling "GetRequestStream" with "0" argument(s): "The requested FTP command is not supported when using HTTP proxy."
At D:\Users\h.yordanov\Desktop\PowerShellFtp-master\script.ps1:21 char:1
+ $Run = $FTPRequest.GetRequestStream()
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : InvalidOperationException

And the script i used is this:

    # Config
$Username = "sammy"
$Password = "1111"
$LocalFile = "C:\fff\medias\1618716-maybach-exelero.jpg"
$RemoteFile = "ftp://192.168.56.101/files/1618716-maybach-exelero.jpg"

# Create FTP Rquest Object

    $FTPRequest = [System.Net.FtpWebRequest]::Create("$RemoteFile")
    $FTPRequest = [System.Net.FtpWebRequest]$FTPRequest
    $FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::UploadFile

    $FTPRequest.Credentials = new-object System.Net.NetworkCredential($Username, $Password)
    $FTPRequest.UseBinary = $true
    $FTPRequest.UsePassive = $true
    # Read the File for Upload
    $FileContent = gc -en byte $LocalFile
    $FTPRequest.ContentLength = $FileContent.Length
    # Get Stream Request by bytes
    $Run = $FTPRequest.GetRequestStream()
    $Run.Write($FileContent, 0, $FileContent.Length)
    # Cleanup
    $Run.Close()

$Run.Dispose()

The powershell ver is 5.1. I have proxy on the host machine.

Edit: I'm using the download command now:

# Config
$Username = "sammy"
$Password = "1111"
$LocalFile = "C:\fff\medias\1618716-maybach-exelero.jpg"
$RemoteFile = "ftp://192.168.56.101/files/1618716-maybach-exelero.jpg"

# Create a FTPWebRequest 
$FTPRequest = [System.Net.FtpWebRequest]::Create($RemoteFile) 
$FTPRequest.Credentials = New-Object System.Net.NetworkCredential($Username,$Password) 
$FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile 
$FTPRequest.UseBinary = $true 
$FTPRequest.KeepAlive = $false
# Send the ftp request
$FTPResponse = $FTPRequest.GetResponse() 
# Get a download stream from the server response 
$ResponseStream = $FTPResponse.GetResponseStream() 
# Create the target file on the local system and the download buffer 
$LocalFileFile = New-Object IO.FileStream ($LocalFile,[IO.FileMode]::Create) 
[byte[]]$ReadBuffer = New-Object byte[] 1024 
# Loop through the download 
    do { 
        $ReadLength = $ResponseStream.Read($ReadBuffer,0,1024) 
        $LocalFileFile.Write($ReadBuffer,0,$ReadLength) 
    } 
    while ($ReadLength -ne 0)

But atm i have this error:

Exception calling "GetResponse" with "0" argument(s): "The remote server returned an error: (403) Forbidden."

    + FullyQualifiedErrorId : WebException

Second edit:

# Load WinSCP .NET assembly
Add-Type -Path "D:\Users\h.yordanov\Desktop\PowerShellFtp-master\WinSCPnet.dll"

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "192.168.56.101"
    UserName = "sammy"
    Password = "1111"
}

# Configure proxy
$sessionOptions.AddRawSettings("ProxyMethod", "1")
$sessionOptions.AddRawSettings("ProxyHost", "proxy.abc.dfg.bg")

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Upload file
    $LocalFile = "C:\fff\medias\test2.txt"
    $RemoteFile = "/home/sammy/ftp/files/test2.txt"
    $session.PutFiles($LocalFile, $RemoteFile).Check()
}
finally
{
    $session.Dispose()
}

After this i get this error:

Exception calling "Open" with "1" argument(s): "Connection failed.

I dont see any proxy connection here.

Answer 1

The FtpWebRequest does not support an HTTP proxy for some operations, including file upload. It's clearly documented on MSDN :

If the specified proxy is an HTTP proxy, only the DownloadFile, ListDirectory, and ListDirectoryDetails commands are supported.

There's no way to upload a file to FTP over an HTTP proxy with PowerShell and the standard .NET framework libraries.

You have to use a 3rd party FTP library or PowerShell module.

For example with WinSCP .NET assembly , you can use:

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "ftp.example.com"
    UserName = "user"
    Password = "mypassword"
}

# Configure proxy
$sessionOptions.AddRawSettings("ProxyMethod", "3")
$sessionOptions.AddRawSettings("ProxyHost", "proxy")

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Upload file
    $LocalFile = "C:\fff\medias\1618716-maybach-exelero.jpg"
    $RemoteFile = "/files/1618716-maybach-exelero.jpg"
    $session.PutFiles($LocalFile, $RemoteFile).Check()
}
finally
{
    $session.Dispose()
}

For the options for SessionOptions.AddRawSettings , see raw settings .

You can have WinSCP GUI generate a PowerShell FTP upload code template , like above, for you.

Though your actual problem is that you have proxy configured in your Internet connection options on your machine, while you actually do not want to use them.

The correct solution is to fix the options.
Go to Control panel > Network and Internet > Internet Options > Connections > LAN settings .

Or as workaround, disable the proxy for a particular connection in your PowerShell code:

$FTPRequest.Proxy = [System.Net.GlobalProxySelection]::GetEmptyWebProxy()

See powershell http get not use proxy .
