![]() ![]() Use SFTP or SCP to copy the public key file (for example, /.ssh/idrsa. pub extension added) and stored in the same location (for example, /.ssh/idrsa.pub or /.ssh/mysshkey.pub). Known_hosts file is maintained on ssh client, authorized_key file is maintained on the ssh server. The ssh-copy-id tool is included by default in many operating systems, so you may have it available on your local system. The corresponding public key will be generated using the same filename (but with a. The authenticity of host 'server (10.10.10.10)' can't be established.ĮCDSA key fingerprint is SHA256:1234567891011121314+7777+999999999999999999.Īre you sure you want to continue connecting (yes/no/)?Ĭonnecting to a ssh server via ip address then next time via ip address will result in 2 entries in the ssh clients ~/.ssh/known_hosts file EXAMPLES To send a specific key to multiple hosts: ssh-copy-id -i. The first time you SSH into a SERVER its public key is copied/ hashed into your local computers ~/.ssh/known_hosts file. EXIT STATUS The ssh-copy-id utility exits 0 on success, and >0 if an error occurs. ![]() When a SSH SERVER is provisioned it creates a bunch of key-pairs in its /etc/ssh directory. ~/.ssh/authorized_keys holds a list of public keys that are authorised to login to the computer.Īuthorized_key file is maintained on the ssh server, known_hosts file is maintained on ssh client Known_Hosts This will copy the public key into remote_server:/home/remote_user/.ssh/authorized_keys Default Key ssh-copy-id Specify Key ssh-copy-id -i ~/.ssh/contractor Authorized_Keys With this cryptographic protocol, you can manage machines, copy, or move files on a remote server via encrypted channels. +-+ ls /home/user/.ssh id_rsa id_rsa.pub Specify Type ssh-keygen -t | dsa | ecdsa | ed25519 | rsa Specify Bits ssh-keygen -t rsa -b 4096 ssh-keygen -t ecdsa -b 521 Specify Comment ssh-keygen -C contractor Specifying File Name ssh-keygen -f ~/contractor Generate Public Key from Private Key ssh-keygen -y -f server.id_rsa > server.id_rsa.pub Copy Public Key to Remote Server Copy your keys to the remote machine: ssh-copy-id usernameremotehost Copy the given public key to the remote: ssh-copy-id -i path/to/certificate usernameremotehost Copy the given public key to the remote with specific port: ssh-copy-id -i path/to/certificate -p port usernameremotehost tldr. SSH (Secure Shell) allows secure remote connections between two systems.
