On standard cloud images of Linux operating systems like Ubuntu and Fedora SSH access is restricted to public key authentication. Instead of authenticating with a password you authenticate with a private key that corresponds to a public key that is installed on the instance.

An SSH key consists of a pair of files. One is the private key, which you should never give to anyone. No one will ever ask you for it and if so, simply ignore them - they are trying to steal it. The other is the public key. When you generate your keys, you will use ssh-keygen to store the keys in a safe location so you can authenticate with. Sep 26, 2019 You generate an SSH key through macOS by using the Terminal application. Once you upload a valid public SSH key, the Triton Compute Service uses SmartLogin to copy the public key to any new SmartMachine you provision. SSH keys can serve as a means of identifying yourself to an SSH server using public-key cryptography and challenge-response authentication.The major advantage of key-based authentication is that in contrast to password authentication it is not prone to brute-force attacks and you do not expose valid credentials, if the server has been compromised.

This HOWTO explains how to use keypairs in OpenStack and how to log in with Putty, a SSH client that runs on Windows. Most steps have to be completed once to get you going.

Note

This HOWTO assumes you have an OpenStack account and the OpenSSH client installed.

Creating a Keypair

If you haven’t created a key before, start with creating a Keypair in OpenStack:

  1. Go to ‘Access & Security’

  2. Open the ‘Keypairs’ tab

  3. Click on the Create Keypair button:

  4. Choose a Keypair Name:

  5. You will now be asked to save a .pem file. Save the file on a convenient location. You won’t be able to download it again.

  6. Open a terminal

  7. Correct the file permissions of the .pem file

    For example:

Inserting a key in a new instance

In order to be able to use the key, you need to insert it in a new instance in OpenStack:

  1. Open the Instances menu on the left

  2. Click on Launch Instance

  3. Choose the relevant options in the Details tab

  4. Select the keypair that you just created:

  5. Complete the rest of the wizard

Associating a floating IP address

To be able to access an instance remotely, a floating IP address needs to be associated to the instance.

  1. Associate a Floating IP address to the instance, by clicking the 'Associate Floating IP' option in the menu on the right:

  2. Pick a Floating IP address from the drop down menu. If no address is available, add one by clicking the + button:

Using the key with OpenSSH

Now we've prepared a key, started an instance and associated a floating IP we can use the key to login the instance with SSH:

  1. Open a terminal

  2. Start a SSH connection with a command like the one below (default username depends on the image, on Ubuntu the username is simply 'ubuntu'):

    For example:

  3. Optionally, you can use the SSH configuration file. Add the following to ~/.ssh/config:

    After that you can simply login with:

  4. If you have connected to a server with the same IP address before, you'll receive a message like the one below.

    When you're connecting to a new instance you can delete the offending key with this command (change the line number to the one in the warning message):

  5. When connecting for the first time you'll be asked the following question. Type 'yes' to continue:

  6. If everything works alright you’re now logged in.

    The software is not only working as a threat protector but also works as a secure search engine. Save wizard cracked. Moreover, the tool becomes very popular among most of the users due to its real-time protection efficiency which completely encounters unexpected and unidentified online threats. Furthermore, the application provides tremendous protection to email and web after the installation process it comes with a full swing for the entire scanning of the system.

You generate an SSH key through Mac OS X by using the Terminal application. Once you upload a valid public SSH key,Gerrit can authenticate you based on this key.

An SSH key consists of a pair of files. One is the private key, which you should never give to anyone. No one will everask you for it and if so, simply ignore them - they are trying to steal it.The other is the public key. When you generate your keys, you will use ssh-keygen to store the keys in a safe locationso you can authenticate with Gerrit.

To generate SSH keys in Mac OS X, follow these steps:

  1. Enter the following command in the Terminal window:

    This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.

  2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase.

  3. Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase). However, this is not recommended.

Warning

You will need to enter the passphrase a second time to continue.

After you confirm the passphrase, the system generates the key pair and you will see output like this:

Your private key is saved to the id_rsa file in the .ssh subdirectory of your home directory and is used to verifythe public key you use belongs to your Gerrit account.

Warning

Never share your private key with anyone! Ever! We mean it!

Your public key is saved to a file called id_rsa.pub in the .ssh subdirectory of your home directory. You can copyit to your clipboard using the following command:

Now you can head over to Gerrit, go to settings and paste your public key as described here.

Gerrit is using the special port 29418 instead of the default SSH port 22 which has to be configured accordingly. This can be done in your local ~/.ssh/config file which would contain the following sections then:
