Options for the ssh-keygen command allow you to specify a different identifier: $ cat. It is a file containing a single line: The protocol, the key, and an email used as an identifier. pub is the public key that needs to be transferred to the remote systems. Some applications will not use keys if the permissions to the private key are too open. 1 training training 415 Aug 12 07:43 id_rsa.pubĪllowing this command to create the directory also ensures that the owner and permissions are set correctly. 1 training training 1843 Aug 12 07:43 id_rsa The default location to store the keys is in the ~/.ssh directory, which will be created if it does not exist: $ ls -al.

Your identification has been saved in /home/training/.ssh/id_rsa. The minimum effort to generate a key pair involves running the ssh-keygen command, and choosing the defaults at all the prompts: $ ssh-keygenĮnter file in which to save the key (/home/training/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): Generating your key pair and propagating your public key is simpler than it sounds. Generating a key pair and propagating the public key A local caching program such as ssh-agent or gnome-keyring allows you to enter that passphrase periodically, instead of each time you use the key to access a remote system. Your private key may be secured locally with a passphrase. The private key remains secure on your own workstation, and the public key gets placed in a specific location on each remote system that you access. Instead of the remote system prompting for a password with each connection, authentication can be automatically negotiated using a public and private key pair. Do not forget to offer us your thoughts about this guide or other useful sudeors configurations for Linux system administrators in the comments.If you interact regularly with SSH commands and remote hosts, you may find that using a key pair instead of passwords can be convenient. In this article, we described how to configure the sudo command to run without entering a password.
