Overview

To use SSH keys on IU Sitehosting, follow the instructions for your OS.

1.We created a new public key on Google Cloud VM as /.ssh/runnhostkey1 /.ssh/runnhostkey1.pub 2.Added the public key runnhostkey1.pub contents to VM Edit SSH Keys. 3.Created a new file in local mac and copied the contents of the public key $ vi /.ssh/runnhostkey1.pub $ chmod 400 /.ssh/runnhostkey1.pub. SiteGround uses key pairs for SSH authentication purposes, as opposed to plain username and password. More information on SSH keys is available here. You can generate an SSH key pair in Mac OS following these steps. Nov 10, 2011  Your public and private SSH key should now be generated. Open the file manager and navigate to the.ssh directory. You should see two files: idrsa and idrsa.pub.

Generate SSH keys on Linux/Mac

1. Generate a public/private key pair:
   1. Log in to the computer you will use to access Sitehost, and then use the command line to generate a key pair. To generate RSA keys, on the command line, enter:
   2. You will be prompted to supply a filename (for saving the key pair) and a passphrase (for protecting your private key):
      • Filename: To accept the default filename and location for your key pair, press Enter or Return without entering a filename. Alternatively, you can enter a filename (for example, my_ssh_key) at the prompt, and then press Enter or Return.
      • Passphrase: Enter a passphrase that contains at least five characters, and then press Enter or Return. If you press Enter or Return without entering a passphrase, your private key will be generated without password protection.
2. Once the key pair has been generated, navigate to the location where you saved the public key.
3. Copy the contents of your public key (this is the file with the .pub extension).
4. Once you copy the contents of your public key, see Add a public key to IU Sitehosting below.

Generate SSH keys on Windows

1. Install PuTTY. The PuTTY command-line SSH client, the PuTTYgen key generation utility, the Pageant SSH authentication agent, and the PuTTY SCP and SFTP utilities are packaged together in a Windows installer available under The MIT License for free download from the PuTTY development team.
2. Launch PuTTYgen.
3. In the 'PuTTY Key Generator' window, under 'Parameters':
   • For 'Type of key to generate', select RSA. (In older versions of PuTTYgen, select SSH2-RSA.)
   • For 'Number of bits in a generated key', leave the default value (2048).
4. Under 'Actions', click Generate.
5. When prompted, use your mouse (or trackpad) to move your cursor around the blank area under 'Key'; this generates randomness that PuTTYgen uses to generate your key pair.
6. When your key pair is generated, PuTTYgen displays the public key in the area under 'Key'. In the 'Key passphrase' and 'Confirm passphrase' text boxes, enter a passphrase to passphrase-protect your private key.
   If you don't passphrase-protect your private key, anyone with access to your computer will be able to SSH (without being prompted for a passphrase) to your account on any remote system that has the corresponding public key.
7. Right-click in the 'Public key for pasting into OpenSSH authorized_keys file' text box, choose Select All, and then right-click in the text box again and select Copy.
8. Save your private key in a safe place. You'll use the passphrase any time you log into a Sitehost server using SSH keys, and you'll need to copy the public key to your profile on the WebTech website. To save your private key:
   1. Under 'Actions', next to 'Save the generated key', click Save private key.
      If you didn't passphrase-protect your private key, the utility will ask whether you're sure you want to save it without a passphrase. Click Yes to proceed or No to go back and create a passphrase for your private key.
   2. Keep 'Save as type' set to PuTTY Private Key Files (*.ppk), give the file a name (for example, putty_private_key), select a location on your computer to store it, and then click Save.
   3. If you wish to connect to a remote desktop system such as Research Desktop (RED), click Conversions > Export OpenSSH key, give the file a name (for example, putty_rsa), select a location on your computer to store it, and then click Save.

If you no longer have the public key, or if it is later determined to be invalid, use the following steps to obtain a public key:

1. Launch PuTTYgen.
2. Click Load.
3. Navigate to your private key and click Open.
4. In the PuTTYgen pop-up window, enter the passphrase.
5. Right-click in the 'Public key for pasting into OpenSSH authorized_keys file' text box, choose Select All, and then right-click in the text box again and select Copy.
6. Select File > Exit to close PuTTYgen.

Add a public key to IU Sitehosting

1. Go to the IU Sitehosting account management.
2. At the top right, click Sign in, and, if prompted, log in with your IU username and passphrase.
3. At the top right, click your name. You'll be taken to the 'Manage your profile' page.
4. Under 'Manage SSH keys':
   1. In the 'Note' field, enter a short description.
   2. In the 'Public Key' field, paste the public key you copied in step 7 above.
5. Click Add. If the public key is valid, it will be added to your profile. Within 30 minutes, the public key will be added to all sitehost-test and sitehost accounts that you own, or for which you are a proxy or developer.

Connect to IU Sitehosting using SSH keys in various applications

With a secure shell (SSH) key pair, you can create virtual machines (VMs) in Azure that use SSH keys for authentication, eliminating the need for passwords to sign in. This article shows you how to quickly generate and use an SSH public-private key file pair for Linux VMs. You can complete these steps with the Azure Cloud Shell, a macOS or Linux host, the Windows Subsystem for Linux, and other tools that support OpenSSH.

Note

VMs created using SSH keys are by default configured with passwords disabled, which greatly increases the difficulty of brute-force guessing attacks.

For more background and examples, see Detailed steps to create SSH key pairs.

For additional ways to generate and use SSH keys on a Windows computer, see How to use SSH keys with Windows on Azure.

Supported SSH key formats

Mac Ssh Public Key Location

Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported.

Create an SSH key pair

Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the ~/.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten.

The following command creates an SSH key pair using RSA encryption and a bit length of 4096:

If you use the Azure CLI to create your VM with the az vm create command, you can optionally generate SSH public and private key files using the --generate-ssh-keys option. The key files are stored in the ~/.ssh directory unless specified otherwise with the --ssh-dest-key-path option. The --generate-ssh-keys option will not overwrite existing key files, instead returning an error. In the following command, replace VMname and RGname with your own values:

Provide an SSH public key when deploying a VM

To create a Linux VM that uses SSH keys for authentication, specify your SSH public key when creating the VM using the Azure portal, Azure CLI, Azure Resource Manager templates, or other methods:

Generate Public Key Ssh Mac

If you're not familiar with the format of an SSH public key, you can display your public key with the following cat command, replacing ~/.ssh/id_rsa.pub with the path and filename of your own public key file if needed:

A typical public key value looks like this example:

If you copy and paste the contents of the public key file to use in the Azure portal or a Resource Manager template, make sure you don't copy any trailing whitespace. To copy a public key in macOS, you can pipe the public key file to pbcopy. Similarly in Linux, you can pipe the public key file to programs such as xclip.

The public key that you place on your Linux VM in Azure is by default stored in ~/.ssh/id_rsa.pub, unless you specified a different location when you created the key pair. To use the Azure CLI 2.0 to create your VM with an existing public key, specify the value and optionally the location of this public key using the az vm create command with the --ssh-key-values option. In the following command, replace VMname, RGname, and keyFile with your own values:

If you want to use multiple SSH keys with your VM, you can enter them in a space-separated list, like this --ssh-key-values sshkey-desktop.pub sshkey-laptop.pub.

SSH into your VM

With the public key deployed on your Azure VM, and the private key on your local system, SSH into your VM using the IP address or DNS name of your VM. In the following command, replace azureuser and myvm.westus.cloudapp.azure.com with the administrator user name and the fully qualified domain name (or IP address):

If you specified a passphrase when you created your key pair, enter that passphrase when prompted during the login process. The VM is added to your ~/.ssh/known_hosts file, and you won't be asked to connect again until either the public key on your Azure VM changes or the server name is removed from ~/.ssh/known_hosts.
