Path questions for -PATH parameter

[VeridianVoid]

No logical version of Path works within windows to windows Posh-SSH. But same paths work in OS-level SCP. Full example :

Via scp command, this works :
scp the_user@the_host:"/C:/TEST_DIR/SOURCE_DIR/TEST_FILE.TXT" "C:\TEST_DIR\TARGET_DIR\newfile.txt"

Setup for POSH :

Remove-Item -Recurse -Force "C:\TEST_DIR\" | Out-Null
mkdir "C:\TEST_DIR\" | Out-Null
mkdir "C:\TEST_DIR\SOURCE_DIR" | Out-Null
mkdir "C:\TEST_DIR\TARGET_DIR" | Out-Null
dir > "C:\TEST_DIR\SOURCE_DIR\TEST_FILE.TXT" | Out-Null

$SFTP_Host        = "the_host"
$SFTP_UserName    = "the_user"
$SFTP_RawPassword = "my_pw!"

Import-Module Posh-SSH 

$SFTP_Password   = ConvertTo-SecureString $SFTP_RawPassword -AsPlainText -Force
$SFTP_Credential = New-Object System.Management.Automation.PSCredential ( $SFTP_UserName, $SFTP_Password )
$FTP_Session     = New-SFTPSession -Computername $SFTP_Host -Credential $SFTP_Credential -AcceptKey

Works great so far, but here is where it fails :
Get-SFTPItem -SFTPSession $FTP_Session -Path "/C:/TEST_DIR/SOURCE_DIR/TEST_FILE.TXT" -Destination "C:\TEST_DIR\TARGET_DIR"

Gives : "The given path's format is not supported."

The only format that does work is (this is the only way the command seems to work):
Get-SFTPItem -SFTPSession $FTP_Session -Path "../../TEST_DIR/SOURCE_DIR/TEST_FILE.TXT" -Destination "C:\TEST_DIR\TARGET_DIR"

But as you can see, there's no way to specify the drive.

This is a trivial example, is there documentation for pathing with posh-ssh? Am I missing something? Is this a windows-ish bug?

seems the problem is here for files
and here for folders

under v5.1 [System.IO.FileInfo]::new('/C:/Users') gives this error

I believe both should be changed to [System.IO.Path]::GetFileName(remotepath)

Gonna see when I can setup a windows server with OpenSSH to test. I also found this on the library side sshnet/SSH.NET#171

[MVKozlov]

It does not work only on v5.1, v7 have no problems

[darkoperator]

ok, that helps, will try out the changes you recomended, just finished setting up a SFTP on Windows. Thinking of dropping 5.x and moving everything to 7.4 at some point, but in the mean time need to fix this

[MVKozlov]

5.1 still widely used because it intergrated
and afaik Azure use it too

[darkoperator]

Main reason is that SSH.NET is going all of it new cipher and algorithm support to .Net 8, if I move the module to .Net 8 it will only run on 7.4 and above, .Net 8 assemblies are not supported in 5.1 to 7.0-7.3

[MVKozlov]

I think it's really time to learn how to make a multiplatform module :)
Especially if the main difference is in the base library, and not in the module itself.
True, then the versions under different posh will have different features, but at least the baseline version support will remain

[darkoperator]

should be fixed now in 3.2.1, just pushed it to the gallery
