Problem connecting

2014-12-30 19:04

Hi there, I am receiving this message when trying to connect to a server via SFTP:

Unable to use key file "?C:\Services\PrivateSSHKeyNP.ppk" (unable to open file) Using username "myuser". Authentication failed.

SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Sftp,
HostName = "someserver.com",
PortNumber = 22,
UserName = "myuser",
SshHostKeyFingerprint = <host fingerprint>,
SshPrivateKeyPath = "C:\Services\PrivateSSHKeyNP.ppk"
};

The key file was made with PuttyGen and I can use your client application and a different FTP client to connect using this Private Key file.
The Private Key file has no password.

What am I doing wrong?

Your string syntax is wrong. You have to escape the backslashes. Either use "C:\\Services\\PrivateSSHKeyNP.ppk" or @"C:\Services\PrivateSSHKeyNP.ppk".

If this does not help, please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.
