Make a copy of the user folder and delete it before recreation.PuTTY is a free-to-use, open-source, and easy-to-use terminal application. The user can be recreated using the following command:

Then you have to re-create the user and follow the steps and configure the public key again.

If the configuration is correct, the connection will be established successfully Now, the key based authentication can be verified with PuTTY. ssh folder and authorized_keys file for access permissions Ssh-keygen -if public_key > public_key_openssh_formatĪdd the created openSSH public key to authorized_keys filesĬat public_key_openssh_format > ~/.ssh/authorized_keysĬheck the permissions of. Use ssh-keygen tool to create openSSH format public key Since the public key does not have any permissions, change it to 400 (for read) Login to SSH server verify the copied public key Trying to connect using the new key, I get the response that ' Server refused our key'.Ĭopy the public key in to SSH Server via SFTP I then copied these files to the Windows machine, and used PuTTYgen to convert the private key to a PuTTY private key format ( *.ppk). Trying to use > ssh-add id_rsa was not successful, as I git the reply that ' Could not open a connection to your authentication agent.', so I just used > cp id_rsa.pub authorized_keys. It generated a id_rsa private key and id_rsa.pub public key. Update: Thinking the problem might be with the PuTTYgen key format, I used ssh-keygen on the Linux machine to create an RSA keypair. How do I use this with pscp (rather than PuTTY's ssh)? How should I set up a public key connection form Win 7 to Linux? I then tried to copy-paste the public key text from PuTTYgen's GUI to the authorized_keys file, but it did not work either. However, when trying to connect using PuTTY's SSH, the connection uses the preset username, but I get an error message of ' Server refused our key' and a prompt for the password. To check the connection, I run PuTTY and set the username and private key file in the appropriate places in its GUI. I then copied the generated public key to a ~/.ssh/authorized_keys file on the Linux machine (as far as I can tell, it runs OpenSSH server).

The ultimate purpose is to use pscp (PuTTY's version of scp) from the command terminal w/o the need to type password repetitively.įollowing PuTTY's documentation and other online sources, I used PuTTYgen to generate a key pair.

I am trying to set a public SSH key connection from a Windows 7 machine to a Red-Hat Linux machine.
