Solution 1: Generate and Add SSH Key Pair So, by examining your reason, you can choose the relevant solution. You must also know why this “ssh permission denied publickey” arose at your end. These can be fixed by manipulating the sshd_config file.Īt the moment, we have described the possible reasons for this failure. There may be configuration issues on the server side, such as incorrect permissions on the server’s home directory, incorrect configuration of the authorized_keys file, or disabled public key authentication in the SSH server’s configuration. The agent should be running and properly configured to handle the private key. If an SSH agent is being used to manage the private key, there may be issues with the agent or its configuration. This can be encountered by creating a Key pair and ensuring the file key pair is configured correctly. The key pair (public and private key) may have needed to be generated properly using a tool like ssh-keygen. The private key should have restricted permissions (600 or 400), and the authorized_keys file on the server should have appropriate permissions (600 or 644) and be owned by the correct user. The permissions on the client’s private key or the server’s authorized_keys file may be set incorrectly. The client’s private key must be correctly associated with the public key at the server’s end. The private key stored on the client system may need to be corrected or added. The public key must be accurately copied and configured on the server’s authorized_keys file. The public key used by the client may need to be corrected or matched with the corresponding private key stored on the client system or configured on the server. Let’s describe them one by one: Incorrect Public Key However, there are several potential reasons behind this publickey failure. The core reason for this error is concerns with the publickey. How to Fix the “ssh permission denied publickey” Error? However, we practiced the commands on Ubuntu 22.04. In this post, we will list the possible reasons and propose solutions to encounter/fix the “ssh permission denied publickey.” The SSH-related commands are the same across all the Linux distributions. There are several core reasons behind this activation failure. The “denied publickey” error occurs when the SSH fails to authenticate the client using public key cryptography. Sometimes, while establishing an SSH connection, you will encounter the “Permission denied (publickey)” error in SSH. With this protocol, the server relates to the client to perform several operations, including system/network-based administration, file transfer, etc. I basically downloaded the id_rsa stored in my google drive, set it under ~/.ssh/ and made sure that the id_rsa key file had 644 perms using chmod 644 id_rsa.SSH (Secure Shell) is a network protocol allowing secure communication. I get the following error: home//.ssh (Permission denied), where is my username on the ubuntu machine. The problem is that when setting up dbeaver on another computer (ubuntu) to setup an ssh tunnel to connect to remote server instance. the key is password protected and that works fine on my mac and on that google colab script using the key stored in my google drive. I also uploaded that private key to a google drive and I'm able to use that same key to authenticate to the remote server from a script setup on google colab notebook. I generated id_rsa (private and pub) keys using ssh-key gen on a mac machine, there, I was able to setup dbeaver with the private key to authenticate to the remote server.
