You need to convert your private key to putty format using puttygen tool.

Hi,
I have generated my keys with puttygen but I can't get the public key auth working.
I exported the public key as openssh key to store it in my authorized_keys file on the server but I always get the error message "Key is of wrong type (PuTTY SSH-2 private key)".
What I'm doing wrong? :cry:

TIA
Torsten

Doh! :shock: I found my error.
I was using version 1 as preferred ssh version.
When I changed it to version 2 everything started working as expected.
Sorry for any inconvenience caused.

Best regards

You really need a smiley which is banging his head against a wall :mrgreen:

Hi,

I am trying WinSCP as SFTP client and freeSSHD as server. How to setup user name in SSH server.

I get error message as below:
***
Authentication log (see session log for details):
Using username "john".
Authenticating with public key "dsa-key-20050727"
Access denied
No supported authentication methods left to try!

Connection has been unexpectedly closed. Server sent command exit status 0."

Please advise and thanks.

Generally you do not setup username on SSH server. The server typically uses account base of the system. However I do not know freeSSHD.
