Install Openssh On Mac



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.

Instructions on how to install OpenSSH on your iPad using Cydia Installer. Get the iClarified app for iPhone, iPad, iPod touch, Mac OS X, and Apple Watch! Once you change that bit after installing and a reboot, you should have sshd running for login and ssh in /usr/local/bin/ssh for your own use. Anyway, give it a go if you want. I'm pretty sure my package won't make your Mac explode, but bad things can happen.:) BTW, PackageMaker is pretty cool. It was much easier to bundle it up than I thought.

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.

About Terminal

Terminal is the terminal emulator which provides a text-based command line interface to the Unix shell of macOS.

To open the macOS Terminal, follow these steps:

  1. In Finder, choose Utilities from the Applications folder.
  2. Find Terminal in the Utilities listw.
  3. Open Terminal.

The Terminal window opens with the commandline prompt displaying the name of your machine and your username.

Generating an SSH key

An SSH key consists of a pair of files. One is the private key, which should never be shared with anyone. The other is the public key. The other file is a public key which allows you to log into the containers and VMs you provision. When you generate the keys, you will use ssh-keygen to store the keys in a safe location so you can bypass the login prompt when connecting to your instances.

To generate SSH keys in macOS, 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.

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

After you confirm the passphrase, the system generates the key pair.

Your private key is saved to the id_rsa file in the .ssh directory and is used to verify the public key you use belongs to the same Triton Compute Service account.

Never share your private key with anyone!

Your public key is saved to the id_rsa.pub;file and is the key you upload to your Triton Compute Service account. You can save this key to the clipboard by running this:

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.

Troubleshooting

You may see a password prompt like this:

This is because:

  • You did not enter the correct passphrase.
  • The private key on your Macintosh (id_rsa) does not match the public key stored with your Triton Compute Service account.
  • The public key was not entered correctly in your Triton account.

What are my next steps?

Right in the portal, you can easily create Docker containers, infrastructure containers, and hardware virtual machines.

In order to use the Terminal to create instances, set up triton and CloudAPI as well as the triton-docker commandline tool.

Applies to Windows Server 2019, Windows 10

OpenSSH is a connectivity tool for remote login that uses the SSH protocol. It encrypts all traffic between client and server to eliminate eavesdropping, connection hijacking, and other attacks.

OpenSSH can be used to connect Window 10 clients to Windows Server 2019. OpenSSH Client is available to install on Windows 10 build 1809 and later, while OpenSSH Server is available to install on Windows Server 2019 and later.

Important

If you downloaded OpenSSH from the GitHub repo at PowerShell/openssh-portable, follow the instructions listed there, not the ones in this article.

Install OpenSSH using Windows Settings

Openssh

Both OpenSSH components can be installed using Windows Settings. OpenSSH Server is installed on Windows Server and OpenSSH Client is installed on Windows 10 devices.

To install the OpenSSH components:

  1. Open Settings, select Apps > Apps & Features, then select Optional Features.

  2. Scan the list to see if the OpenSSH is already installed. If not, at the top of the page, select Add a feature, then:

    • On Windows 10, find OpenSSH Client, then click Install
    • On Windows Server 2019, find OpenSSH Server, then click Install

Once setup completes, return to Apps > Apps & Features and Optional Features and you should see OpenSSH listed.

Note

Installing OpenSSH Server will create and enable a firewall rule named OpenSSH-Server-In-TCP. This allows inbound SSH traffic on port 22. If this rule is not enabled and this port is not open, connections will be refused or reset.

Install OpenSSH using PowerShell

To install OpenSSH using PowerShell, run PowerShell as an Administrator.To make sure that OpenSSH is available, run the following cmdlet:

This should return the following output:

Install Openssh On Mac Os

Then, install the server or client components as needed:

Both of these should return the following output:

Start and configure SSH Server

To start and configure OpenSSH server for initial use, open PowerShell as an administrator, then run the following commands to start the SSHD service:

Connect to SSH Server

Once installed, you can connect to OpenSSH Server from a Windows 10 device with the SSH client installed using PowerShell as follows. Be sure to run PowerShell as an administrator:

Once connected, you get a message similar to the following:

Selecting yes adds that server to the list of known ssh hosts on your Windows client.

You are prompted for the password at this point. As a security precaution, your password will not be displayed as you type.

Once connected, you will see the Windows command shell prompt:

Uninstall OpenSSH using Windows Settings

To uninstall OpenSSH using Windows Settings:

  1. Open Settings, then go to Apps > Apps & Features.
  2. Go to Optional Features.
  3. In the list, select OpenSSH Client or OpenSSH Server.
  4. Select Uninstall.

Uninstall OpenSSH using PowerShell

To uninstall the OpenSSH components using PowerShell, use the following commands:

You may need to restart Windows afterwards if the service was in use at the time it was uninstalled.
