If you do so, Putty fails with “Server refused our key” error message during authentication. Similarly, it’s not possible to install a Puttygen-generated public-key directly into OpenSSH authorized_keys file. Otherwise, the public-key authentication failed with message that says “Unable to use key file “E:\id_rsa” (OpenSSH SSH-2 private key)”. Having said that, you can’t install OpenSSH-generated private key in Putty program.
However, there is incompatibility issue between RSA type of public key generated by ssh-keygen and Puttygen. With OpenSSH, default SSH client/server software bundled with most Linux distributions, the ssh-keygen program is used to generate a pair of such cryptographic keys.Īs for Putty, popular SSH client suite for Windows, there is this Puttygen program to provide similar functions of ssh-keygen. Other than security benefit, using public-key cryptography in SSH protocol is relatively easier to implement password-less or non-interactive authentication.įor example, a scheduled shell script can use scp (secure copy) to automate file-transfer between hosts seamlessly in background, without user interaction during authentication stage. I was able to log into the server on two seperate days BEFORE I added Firewalld and opened ports 5, but now I can't access the server at all, then the game crashed and I was forced to log back into putty and start it but then I got the error "Server refused our key" along with a window that said "No supported authentication methods available (Server sent: publickey) I hear people talking about a terminal on the Oracle Cloud website but I have no idea where that is or how to open it (Is it local Connection?) anyway I have a bunch of erors thhat appeared all at once and I don't know how to fix any of it and I can't find anything elsewhere.The SSH-2 protocol supports few user authentication types, one of which is public-key cryptography. I have very little knowledge so nothing I have found makes sense to me, or if it does it just doesn't seem to fix it.
I was gonna try setting a new key but I don't know what password is needed to use local connection because I know I didn't set one. I want to host a Modded minecraft server on Oracle Cloud using Ubuntu, However I can't get back in the same way I did before with Putty or Filezilla.
