Passwordless SSH (sftp) key

Post by niqbert »

Passwordless SFTP over SSH doesn't seem to work.

I generated a key via "ssh-keygen -t rsa", with empty passphrase. ( http://www.wftpserver.com/bbs/viewtopic.php?f=5&t=502" rel="nofollow )
Copied over the pub file to the WingFTP server and set the pub file at the account settings in WingFTP.

Any idea what goes wrong and how I can get passwordless connections going with priv/pub keys?

[testsftp@testserver ~]$ sftp -v testuser@sftpserver

Hi,

It seems like the server not process the public key authentication. Please send the user's configure file to us:support@wftpserver.com. We will help you to check it.
