Try opening a remote session on your server machine by issuing the following command on your client machine: Let’s start with just the basics of using ssh from the command line. I will assume in the rest of this document that you are using atria as your server. If you choose to use sirius.cs.odu.edu for your client machine, then use atria.cs.odu.edu for your server, or vice versa. This could be one of the CS Dept Linux servers, or from a terminal session on your own PC if it runs Linux, OS/X, or CygWin.Ī server machine, which will be one of the CS Dept Linux servers. You will be working withĪ client machine, at which you can issue ssh commands. We’re going to start by working with ssh from a command line. You should already be familiar with ssh even if you are used to invoking it through PuTTY. The files it creates are in a unique format but work perfectly well when used with the PuTTY SSH client.SSH keys are a convenience for interating with our Dept Linux servers and a necessity for the Dept Gitlab and other network services.

PuTTY - Download the full PuTTy package and generate an RSA keypair at least 2048 bits in size using the PuTTYGen. Works with Linux-compatible SSH keys, and profiles can be saved. SSH in Chrome Browser - Run an SSH client within the Chrome browser.

GitBash - Download and install GitBash 1, which allows you to run Linux-style commands such as ssh (for secure shell connections) and ssh-keygen to generate keypairs. We suggest swapping out keys every 90-180 days. Be sure to rotate out older keys on a regular basis. One risk of SSH keys is that they have no expiration date or specific lifespan. bashrc file for easy logins, for example: rivanna='ssh -i ~/path/to/file Expiration So while a normal SSH connection looks like this (prompting you for a password): ssh should now instead use something like this (that requires no password): ssh -i ~/path/to/file can add an alias in as a new line in your. Use key authentication for SSH connections - Second, when you invoke the ssh client from your local workstation, use the -i flag to specify your identity file (i.e. Be sure the key is entirely on only one line. (If you do not, create one.) And then paste your public key into that file. ssh/ folder on the remote server, you should find a file named authorized_keys.

Then SSH into your destination server using a password as normal. To use your SSH keypair for authentication, you need to do two things:Ĭopy the public key to your destination server - First, cat out your public key, and copy it to your clipboard. Note that the private key has restricted permissions, This is optional, but should be used in high security environments.Īfter key generation you will find two new files in your.

By default, the key is usually named id_rsa and is placed within a hidden. This command will prompt you for a name and location of the key pair. If you receive an error, you may need to install the openssl package. Create an SSH keypairįrom a terminal or command prompt (Linux and MacOS) issue this command: ssh-keygen Public keys, by contrast, can be shared widely. Anyone with possession of that key can potentially sign into other systems as you. That should remain safely and securely with you. The most important thing to remember about SSH key pairs is to NEVER share or distribute the private half. Or, put it more simply, when data is encrypted using one half of the key, it can be decrypted using the other half. When users use the private key to connect to a server that is configured with the public key, the match can be verified and the user is signed in. One half of the pair is called the “private” key, and the other half is the “public” key. SSH keys are a pair of encrypted files that are meant to go together.

The instructions below describe how to create a key and use it for password-less authentication to your Linux instances. Users can authenticate their SSH sessions using either a password or an ssh key.
