Additionally, it handles file transfer interruptions elegantly. It uses delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. RSYNC is a robust tool for transferring large files securely. Learn more about those commands (‘put’ and ‘get’) here. You can use ‘help’ command to learn how to move files from local machine to remote and vice versa. First, you need to connect to your remote machine using the command below:Īfter successful authentication, you will be inside a sftp session. Like SCP, SFTP client is also included in Bash shell in most Linux and Mac computers as well as PowerShell. SFTP is another easy-to-use tool for transferring files over SSH and it replaces FTP. sshconfig -r folder-to-be-copied 1.2.3.4:~/ SFTP sshconfig 1.2.3.4:~/file /local-directoryĮxample for copying a folder from local to remote: Now that the configs are ready, we can use SCP using the commands below: From local to remote At the time of writing this post, there is a time limit for validity of the certificates and SSH keys. Important note: The config file contains sensitive information and should be deleted when not needed. Please refer to Microsoft official documentation for more details on this topic. These config files can be used by any client that supports OpenSSH configs and certificates. This will generate Azure certificates and SSH keys required for connection. Or it can be generated as a generic config file to use with any host: $ az ssh config -resource-group myResourceGroup -name myVm -file. The config file can be generated for one specific virtual machine using these commands: Using VM IP address $ az ssh vm -resource-group myResourceGroup -name myVM You are already familiar with login with AD using the command below: If you login to your Azure virtual machine using Azure Active Directory (AD), you need to create a temporary config file to use with SCP (thanks to Nigel Sim post). $ scp :target-directory/file /local-directory 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. If you are using Azure virtual machines and login with Azure Active Directory, you will get more instructions on how to connect. The last method is specific to Microsoft Azure and requires a bit of setup by Azure administrator as well as installing some software. The first three methods can be used to access any virtual machines that you have ssh connection. We 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. So, I again tried like below scp /mnt/c/Users/test/test1.There is a common need for our researchers to securely transfer small or large files to virtual machines for various purposes. Later, I tried the below commands as well scp /mnt/c/Users/test/test1.zip got an error scp: /home/test/codes/test1.zip: Permission denied Ssh: connect to host 172.xx.xxx.xxx port 22: No route to host lost connection Later, I tried with IP address scp I got the below error Ssh: Could not resolve hostname lauda: Temporary failure in name resolution Now I tried the same command as above but in opposite way as shown below scp got the below error So I tried the below scp resulted in error as ssh: connect to host 172.xx.xxx.xxx port 22: Connection refused So, I tried the below command from my WSL scp got the error ssh: Could not resolve hostname lauda: Name or service not known PLEASE NOTE THAT ALL COMMANDS ARE TRIED FROM MY LOCAL LAPTOP WSL SCREEN Now, I would like to transfer this zip file called test1.zip to my remote server named stuff. I have a file called test1.zip in /mnt/c/Users/test/ folder of my local laptop.
