![]() ![]() ![]() ![]() Your public key has been saved in mykey.pub. Enter file in which to save the key (/home/ylo/.ssh/id_rsa): mykey Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in mykey. # ssh-keygen Generating public/private rsa key pair. In the simplest form, just run ssh-keygen and answer the questions. With OpenSSH, an SSH key is created using ssh-keygen. The purpose of ssh-copy-id is to make setting up public key authentication easier. Key based authentication in SSH is called public key authentication. If you are interested to learn more about the difference between SCP and RSYNC, read the discussions on this Stackoverflow question.Contents Setting up public key authentication Generate an SSH Key Copy the key to a server Test the new key Troubleshooting How ssh-copy-id works Some best practices for SSH keys Use a passphrase when possible Add a command restriction when possible Managing SSH keys Command-line options Ssh-copy-id on Mac Installation using Homebrew Installation from MacPorts Installation using Curl Setting up public key authentication Azure Storage Explorer uses AzCopy under the hood for data transfer operations. You can follow the updates here.ĪzCopy is another command-line tool for transferring files to and from Azure storage account. There is an open feature request on Azure-cli Github repository to add the functionality to azure-cli tool to copy files to/from virtual machines. You can start transferring files to the mounted drive. Once the file shares are mounted, they can be treated like normal drives on the machine. Alternatively, if you have access rights, you can use Azure portal and storage account to do file transfer operations from browser. If this port is closed in your network, you can download free Azure Storage Explorer on your machine to upload and download files in file share. There is a requirement for SMB 3.0 to use TCP port 445 to establish a secure connection.Otherwise, the OS must support the encryption functionality of SMB 3.0. Azure Storage Account and the virtual machine need to be in the same Azure region.Please note that mounting the shares on local machines and virtual machines is similar with some consideration: When your file share(s) are created, follow instructions for mounting the shares in Windows or Linux from the links provided. Here are official instructions on the Microsoft website. There are many well-written tutorials on how to set up Azure Storage account and create a file share. Azure Files shares between local and virtual machines For Azure Admins You can mount the file shares to virtual machines and local machines as illustrated in the image below. Azure file shares can be mounted in Windows, Linux, and macOS. sshconfig ' -avP 1.2.3.4:~/file /local-directory Azure File ShareĪzure Files is a fully managed service for file shares in the cloud which are accessible via SMB (Server Message Block) protocol or NFS (Network File System) protocol. If you created your key pairs with a passphrase, you will be prompted to enter the passphrase. However, if you are using SSH key pair authentication, SSH will authenticate you using your private key and there is no need to enter your password (best practice). If you are using username and password for SSH authentication, you will be prompted to enter your password. You need a SCP client which is included in Bash shell of most Linux distributions and Mac computers and PowerShell. It uses the same authentication and security as SSH. SCP is a common tool for secure copy files between a local and remote machine. The last method is specific to Microsoft Azure and requires a bit of setup by Azure administrator as well as installing some software. If you are using Azure virtual machines and login with Azure Active Directory, you will get more instructions on how to connect. The first three methods can be used to access any virtual machines that you have ssh connection. I decided to write down four ways to achieve this goal. In this post, we will not go through performance considerations for each tool/method. There are no requirements for retaining the permissions on the files being transferred. We are referring to Linux virtual machines in this post unless we explicitly mention Windows virtual machines as well. They also need to download some result files or data to their local machines. ![]() There is a common need for our university researchers to securely transfer small or large files to virtual machines for various purposes. ![]()
