You can also install the Windows Subsystem for Linux to connect to your VM over SSH and use other native Linux tools within a Bash shell. You can use Cloud Shell in a web browser, from the Azure portal, or as a terminal in Visual Studio Code using the Azure Account extension. You can also use Bash in the Azure Cloud Shell to connect to your VM. Recent versions of Windows 10 include OpenSSH client commands to create and use SSH keys and make SSH connections from PowerShell or a command prompt. Other key formats such as ED25519 and ECDSA are not supported. Supported SSH key formatsĪzure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Your public key can be shared with anyone, but only you (or your local security infrastructure) should have access to your private key. You don't need a separate pair of keys for each VM. If the client has the private key, it's granted access to the VM.ĭepending on your organization's security policies, you can reuse a single key pair to access multiple Azure VMs and services. When you connect to your Linux VM, the VM tests the SSH client to make sure it has the correct private key. The private key remains on your local system. The public key is placed on your Linux VM when you create the VM. The key is private, and only given to people you trust because it can be used to unlock the door. The lock is exposed to the public, anyone with the right key can open the door. The public-private key pair is like the lock on your front door. We recommend connecting to a VM over SSH using a public-private key pair, also known as SSH keys. Although SSH itself provides an encrypted connection, using passwords with SSH still leaves the VM vulnerable to brute-force attacks. SSH is the default connection protocol for Linux VMs hosted in Azure. SSH is an encrypted connection protocol that allows secure sign-ins over unsecured connections. For a more detailed overview of SSH, see Detailed steps: Create and manage SSH keys for authentication to a Linux VM in Azure. To use SSH keys from a Linux or macOS client, see the quick steps. You can also generate and store SSH keys in the Azure portal to use when creating VMs in the portal. This article is for Windows users who want to create and use secure shell (SSH) keys to connect to Linux virtual machines (VMs) in Azure. Continue moving your mouse until the green progress bar is full.Applies to: ✔️ Linux VMs ✔️ Flexible scale sets To create a new key pair, click the Generate button near the bottom and begin to move your mouse around within the window. To begin, locate PuTTY and open PuTTYgen. With Windows, you will use the PuTTYgen.exe graphical tool, while with Linux, you will use the command line. PuTTY stores these key authentications in its. PuTTYgen is a tool that creates SSH key pairs. You can list all available SSH commands by executing help via the terminal. For security reasons, the screen won’t show the password but will register what you type.Ĭongratulations! You have successfully connected to your account using the PuTTY SSH client. Type your SSH password and press Enter again.After entering your username, press Enter. However, for shared hosting users, you will need to enter a predefined username like u721233450. A login as: message will pop up and asks you to enter your SSH username.Launch the PuTTY SSH client, then enter your server’s SSH IP and SSH Port.How to Establish SSH Connection Using PuTTYĪfter getting all the SSH connection information, follow the following steps: If you forgot your password, easily reset it via the FTP Accounts menu. Here you will see all the login details that you need. Shared, WordPress, and Cloud hosting - go to the SSH Access menu under the Advanced category.If you are a Hostinger user, there are two ways to find this information, depending on your hosting plan: To install PuTTY for MacOS: brew install putty (or) port install putty Requirements For Set Upīefore setting up an SSH connection using PuTTY, you will need the following information: But to download PuTTY, open the terminal window and use the commands below. Like Linux, the macOS comes with a command-line SSH client already installed. On Debian, use the following command: sudo aptitude install puttyįollowed by the tools installation command: sudo aptitude install putty-tools MacOS ![]() However, PuTTY on Linux is used more for debugging and connecting to serial ports and to raw sockets. ![]() Most people use the preinstalled OpenSSH on Linux.
