Ssh copy id permission denied7/22/2023 ![]() In addition to that, we check the SSH logs( /var/log/auth.log or /var/log secure) to see why this error occurred. It will therefore give a detailed trace of the connection that will help us to analyze the problem. So, our Support Engineers recreate the problem by connecting to the server via SSH in debug mode. Since publickey is shown in the error message, it doesn’t mean that the public key is the problem.Īctually, this error shows that the public key of the Droplet rejects the private key provided during authentication. The error “ Permission denied (publickey)” clearly shows that there is a problem with the SSH keys used for authentication. The public key is placed on the Droplet while the private key is placed on the user’s computer.Īnd, users submit this private key to authenticate and connect via SSH. Permission denied (publickey) in DigitalOcean – What’s this?īefore we go to the reasons of this error, let’s get an idea of this error first.Ī key based authentication needs a private key and a public key pair. Today, we’ll discuss the top 4 reasons of this error and how our Cloud Experts fix them. One such error is “ Permission denied (publickey)“. That was a recent support ticket received at our DigitalOcean Managed Services department where we resolve support queries for web hosts.ĭroplet owners often use key based authentication to improve security on their servers.īut, what happens if these SSH keys are not configured properly? Result is, server denies access and kicks you out with errors. The private key must be kept secure on the local machine.When I access my server via SSH, it returns permission denied (publickey) error in my DigitalOcean Droplet. The ssh-copy-id command only copies the public key to the remote server's authorized_keys file.The user running the ssh-copy-id command must have SSH access to the remote server.The ssh-copy-id command requires that the remote server has an SSH server installed and running. ![]() Check the network connection and make sure that the remote server is running. Connection timed out: This error occurs when the remote server is not responding.Check the network connection and make sure that the remote server is accessible. No route to host: This error occurs when there is no network connection to the remote server.Make sure that the public key is in the correct location and that the private key has the correct permissions. Permission denied (publickey): This error occurs when the SSH key pair is not set up correctly.Here are some common issues that may arise when using the ssh-copy-id command and their solutions: Specifies an option to pass to the SSH client Specifies the port number to use for the SSH connection Specifies the identity file (private key) to use for authentication The following table lists the available options for the ssh-copy-id command. The basic syntax of the ssh-copy-id command is as follows: ssh-copy-id options are the command options and is the remote server's username and hostname.įor example, if the remote server's username is john and the hostname is, the command would be: ssh-copy-id command will prompt the user for the remote server's password and copy the public key to the remote server's authorized_keys file. It copies the public key to the remote server's authorized_keys file, which allows the user to log in without having to enter a password. This command is used to automate the process of setting up passwordless SSH login. The ssh-copy-id command is a utility that is used to install the public key of an SSH key pair onto a remote server.
