Azure SSH and File Transfer using SCP

SSH Connectivity

To connect via SSH to an Azure Linux VM, use the following PowerShell command substituting the IP address:

az ssh vm --ip <IP Address>

Transfer files using SCP

To transfer files using the command line tool SCP, we must first create public encryption keys which are only valid for 1 hour at a time using the following PowerShell commands:

az ssh config --ip * --file ~/azure-sshconfig --keys-destination-folder ~/azure-keys

This will create the public encryption keys to the user's home folder as a file named azure-keys.

Next, to transfer files from the remote VM to the local computer, use the following PowerShell command substituting the IP/Host, file path, and local destination path:

scp -F ~/azure-sshconfig <IP Address/Hostname>:<Remote File Path> <Local File Path>

For instance, if you wanted to copy Ignition's wrapper log files to the local folder you'd use the following command:

scp -F ~/azure-sshconfig <IP Address/Hostname>:/usr/local/bin/ignition/logs/wrapper.log* .

To transfer files from the local computer to the remote VM , use the following PowerShell command substituting the IP/Host, local file path, and remote destination path:

scp -F ~/azure-sshconfig <Local File Path> <IP Address/Hostname>:<Remote File Path>

To do a recursive copy of an entire folder and it's subfolders, add the -R option in front of the -F option.

As a security measure, you should always delete the encryption keys when finished with the following PowerShell command:

del ~/azure-sshconfig
