Overview

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

You should not manually edit your authorized_keys file in the .ssh directory in your account. Any manual changes made to this file will be purged.

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.

To generate an SSH key in Windows 10: Ensure the Windows 10 OpenSSH client is installed. Run “ssh-keygen” in Command Prompt and follow the instructions to generate your key.

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

On Windows, you can create SSH keys in many ways. This document explains how to use two SSH applications, PuTTY and Git Bash.

Joyent recommends RSA keys because the node-manta CLI programs work with RSA keys both locally and with the ssh agent. DSA keys will work only if the private key is on the same system as the CLI, and not password-protected.

PuTTY

Generate rsa keys without prompt key

PuTTY is an SSH client for Windows. You can use PuTTY to generate SSH keys. PuTTY is a free open-source terminal emulator that functions much like the Terminal application in macOS in a Windows environment. This section shows you how to manually generate and upload an SSH key when working with PuTTY in the Windows environment.

About PuTTY

PuTTY is an SSH client for Windows that you will use to generate your SSH keys. You can download PuTTY from www.chiark.greenend.org.uk.

When you install the PuTTY client, you also install the PuTTYgen utility. PuTTYgen is what you will use to generate your SSH key for a Windows VM.

This page gives you basic information about using PuTTY and PuTTYgen to log in to your provisioned machine. For more information on PuTTY, see the PuTTY documentation

Generating an SSH key

To generate an SSH key with PuTTYgen, follow these steps:

  1. Open the PuTTYgen program.
  2. For Type of key to generate, select SSH-2 RSA.
  3. Click the Generate button.
  4. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair.
  5. Type a passphrase in the Key passphrase field. Type the same passphrase in the Confirm passphrase field. You can use a key without a passphrase, but this is not recommended.
  6. Click the Save private key button to save the private key. You must save the private key. You will need it to connect to your machine.
  7. Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.
  8. Right-click again in the same text field and choose Copy.

Importing your SSH key

Now you must import the copied SSH key to the portal.

  1. After you copy the SSH key to the clipboard, return to your account page.
  2. Choose to Import Public Key and paste your SSH key into the Public Key field.
  3. In the Key Name field, provide a name for the key. Note: although providing a key name is optional, it is a best practice for ease of managing multiple SSH keys.
  4. Add the key. It will now appear in your table of keys under SSH.

PuTTY and OpenSSH use different formats of public SSH keys. If the text you pasted in the SSH Key starts with —— BEGIN SSH2 PUBLIC KEY, it is in the wrong format. Be sure to follow the instructions carefully. Your key should start with ssh-rsa AAAA….

Once you upload your SSH key to the portal, you can connect to your virtual machine from Windows through a PuTTY session.

Generating SSH keys

First, create the SSH directory and then generate the SSH key pair.

One assumption is that the Windows profile you are using is set up with administrative privileges. Given this, you will be creating the SSH directory at the root of your profile, for example:

  1. At the Git Bash command line, change into your root directory and type.
  1. Change into the .ssh directory C:Usersjoetest.ssh

  2. To create the keys, type:
