Also, the file contents are stored in memory before being recorded to the disk, making this approach unsuitable for downloading large files. Another workaround includes installing the Cygwin command line interface for Windows, which features the scp command.
In order to use it, do the following: Download the cygwin installation file from here. SSH handles the authentication on the destination host, and it moves the file in an encrypted tunnel provided by default with SSH. For SSH authentication, usernames and passwords can be used.
However, SSH public and private key authentication are recommended as a security best practice. For the first example, we copy an Azure configuration file up to a Linux VM that is used to deploy automation. Because this file contains Azure API credentials, which include secrets, security is important. The encrypted tunnel provided by SSH protects the contents of the file. The following command copies the local.
The admin user name on the Azure VM is azureuser. Substitute your own values in this command. For this example, we copy a directory of log files from the Linux VM down to your workstation. A log file may or may not contain sensitive or secret data.
However, using SCP ensures the contents of the log files are encrypted. Using SCP to transfer the files is the easiest way to get the log directory and files down to your workstation while also being secure. If you use the Azure CLI to create your VM, you can optionally generate SSH public and private key files by running the az vm create command with the --generate-ssh-keys option.
Note that this command option does not overwrite keys if they already exist in that location. When using the portal, you enter the public key itself.
If you use the Azure CLI to create your VM with an existing public key, specify the value or location of this public key by running the az vm create command with the --ssh-key-value option. If you copy and paste the contents of the public key file into the Azure portal or a Resource Manager template, make sure you don't copy any additional whitespace or introduce additional line breaks.
If you prefer to use a public key that is in a multiline format, you can generate an RFC formatted key in a pem container from the public key you previously created. Replace azureuser and myvm. If you provided a passphrase when you created your key pair, enter the passphrase when prompted during the sign-in process.
If the VM is using the just-in-time access policy, you need to request access before you can connect to the VM. For more information about the just-in-time policy, see Manage virtual machine access using the just in time policy. To avoid typing your private key file passphrase with every SSH sign-in, you can use ssh-agent to cache your private key file passphrase.

To avoid typing your private key file passphrase with every SSH sign-in, you can use ssh-agent to cache your private key file passphrase. If you are using a Mac, the macOS Keychain securely stores the private key passphrase when you invoke ssh-agent. Verify and use ssh-agent and ssh-add to inform the SSH system about the key files so that you do not need to use the passphrase interactively. The following example shows a simple configuration that you can use to quickly sign in as a user to a specific VM using the default SSH private key.
Add configuration settings appropriate for your host VM. In this example, the VM name is myvm and the account name is azureuser. You can add configurations for additional hosts to enable each to use its own dedicated key pair. Sign up using Facebook. Sign up using Email and Password.
