SSH (Secure Socket Shell) is a network protocol that can be used to securely access other machines across a network. From our perspective, using SSH can be valuable, especially if you’re looking to interact with Linux virtual machines such as Matillion servers. For example, SSH protocols could be used to:
- Log into a Linux virtual machine
- Copy files to/from a Linux virtual machine
- Generate SSH keys that can be used for SSH authentication
- Configure authentication to a remote Git repository without entering a password each time you push, pull, etc.
How to Enable SSH Commands in Windows 10
In Windows 10, SSH commands can be executed through PowerShell natively; however, the functionality must be enabled by following these steps:

You should now be able to execute the sshcommand from PowerShell:
Congratulations! You now have a working SSH command that could be used to do a variety of things, as mentioned at the top of this post:
- Log into a Linux virtual machine
- Copy files to/from a Linux virtual machine
- Generate SSH keys that can be used for SSH authentication
- Configure authentication to a remote Git repository without entering a password
