For example, if you use the ForwardAgent or ProxyJump Without the configuration entry, you would need to enter the following: ssh -I ~/.ssh/id_rsa_example can use the $HOME/.ssh/config file to store other configuration optionsįor any system that you connect to. This configuration entry lets you connect with the correct credentials each time you want toĬonnect. The private key file at ~/.ssh/id_rsa_example. The SSH client performs a connection to the remote server With the provided configuration entry, the user can run: ssh server1 Host entries look similar to the following example entry: Host server1 To make it easier toĬonnect easily with the correct credentials, you can add a host entry. Sometimes you might choose to use aĭifferent key pair to your usual key pair for a particular remote system. Often usernames don't align on different systems.
