Please attach a complete session log file from .NET assembly.

Hello, Martin, thank you for the follow-up on all topics.
This may need a new topic, but the site is telling me in read-only mode (so adding here).

I have connections to sites using non-blank passphrases and .ssh public and private keys. I'm successful via the WinSCP GUI, and via the building a running script, and winscp.com

Is it still an issue with the .Net Assembly, to do this?

I've read your threads about two-phase authentication...

Via the GUI, the log shows:

In the .Net code, I set these variables (PowerShell or Perl):

PowerShell here:

# Load WinSCP .NET assembly
Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
Protocol = [WinSCP.Protocol]::Sftp
HostName = "<SITE.SFTP.COM>"
UserName = "XXXXXXX"
SshPrivateKeyPath = "<PATH>\id_rsa.ppk"
PrivateKeyPassphrase = "<MY_KEY_HERE>"
SshHostKeyFingerprint = "<SSH KEY Fingerprint>"
}

$session = New-Object WinSCP.Session
$session.SessionLogPath = "C:\temp\winscp.log"

LOG FROM This (winscp.log) fails immediately, rejecting the key attempt:

What am I doing wrong? (or is this just not possible?)

PowerShell defaults to the ToString() method, which is implemented to return Text in FilePermissions class.

Thank you, Martin!

You rock. This solved (I looked at this, but needed your reminder to realize what had to be done :-) ).

Thanks for your assistance.

Use Text property of the FilePermissions object.
https://winscp.net/eng/docs/library_filepermissions

Hello,

Wanting to understand how the file permissions might be being returned, using Perl and the .Net WinSCP "ListDirectory" functionality.

I followed the examples for both Perl, and for PowerShell, and see how in PowerShell, after reading in the list of files from a remote SFTP site, this print (WriteHost) statement gives straight information I'm coveting in my Perl script:

foreach ($fileInfo in $directory.Files)
{
Write-Host ("$($fileInfo.Name) with size $($fileInfo.Length), " +
"permissions $($fileInfo.FilePermissions) and " +
"last modification at $($fileInfo.LastWriteTime)")
}

Following the same logic, and parameters given, I can duplicate this with Perl, , using Win32::OLE .Net WinSCP method:

my $directory = $session->ListDirectory("/files/");
my $items = Win32::OLE::Enum->new($directory->{'Files'});

However, specifically, the value inside the loop of file objects for FilePermissions:

my $item;
while (defined($item = $items->Next))

for: $item->{'FilePermissions'}

Produces the following sort of output:
FilePermissions = <Win32::OLE=HASH(0x25cc0e0)>
FilePermissions = <Win32::OLE=HASH(0x25cc0f8)>
.
.
.

The same files, in the PowerShell output give:
FilePermissions = <rw-rw-r-->
FilePermissions = <rw-rw-r-->

I tried setting the value returned by 'FilePermissions' to a Hash, and palying around with, but having no luck getting the proper output (And am modifying a program that's written in Perl, so can't really simply go to PowerShell for all of it at this time).

Thank you,
Joe P.
