The WinSCP GUI works fine for me. I used the code found on the site here. I've looked at the forum and can't seem to shake this "Unable to authenticate" message. IF anyone could help, I'd appreciate it! My log is below. Thanks!

It appears I authenticate successfully, but Powershell spits this out:
[b]Connection has been unexpectedly closed. Server sent command exit status 0.[/b]


[quote]$sessionOptions = New-Object WinSCP.SessionOptions
$sessionOptions.Protocol = [WinSCP.Protocol]::Sftp
$sessionOptions.HostName = "<HOST>"
$sessionOptions.UserName = "<USERNAME>"
$sessionOptions.Password = "<PASSWORD>"
$SessionOptions.SshPrivateKeyPath = "C:\tony-newpriv.ppk"
$sessionOptions.SshHostKeyFingerprint = "ssh-rsa 2048 b4:f7:4d:d8:39:da:9e:24:1b:2e:71:8e:e3:2b:3f:fe"[/quote]

Once I added my key to Pageant, everything was working fine and dandy. Neutral
