I've tried to create a private/public key using putty and puttygen although I'm still seeing the password prompt when launching putty with the specified private key in the connection/ssh/auth option. Both the client and server are Windows machines.
On my client machine I ran puttygen and entered a password, then saved the private key to my client machine's c:\key\privatekey.ppk. I then selected all the public key string and copied it to my buffer. I then logged into the server and created a file c:\user\testuser\.ssh\authorized_keys and pasted the public key into it and saved.
whilst on the server I tested I was assuming the right user by launching cmd.exe from the start->run dialog and the prompt was c:\users\testuser>
leaving the server, back on the client I launched putty and specified the private key in the connection/ssh/auth option of putty and then entered the ip address into the hostname: 1.2.3.4
in the prompt I entered the username: testuser (and I also tried domain\testuser) but the server said 'server refused our key' error
Is there something I'm missing/ doing wrong?
Thanks for any help
