OpenSSH in Windows 10: Windows 10 is starting to become a very useful Unix/Linux sysadmin platform. Microsoft’s operating system first integrated the Subsystem for Linux with the Windows 10 Fall Creators Update, and in the latest Windows 10 April 2018 Update, the company added a native Secure Shell (SSH) to Windows.
It took a long time, as Microsoft started working on porting OpenSSH to PowerShell back in 2015 due to user demand.
But finally, you won’t need third-party SSH clients like Putty to connect to a system that has an SSH server. OpenSSH is a collection of client/server utilities that allows developers and system administrators to securely log in, transfer files, and manage public and private keys with any system that has an OpenSSH server.
OpenSSH is commonly used on BSD, Linux, MacOS, and Unix servers, but can be used with any platform (even Windows 10) with an SSH server.
Microsoft reportedly ships the latest version of OpenSSH, OpenSSH 7.7, by default in the Windows 10 April 2018 Update. OpenSSH Server is also available, but you need to install it.
For full instructions on how to use the application, you can visit the OpenSSH page. The most common way to use the application to connect to a remote server is with the following command:
ssh [user]@[host]:[port]
or ssh giorgos@secnews.gr:22
If this is your first connection to that SSH server, the host's key fingerprint will be displayed and you will be asked to confirm that you want to connect. If you answer yes, the host key will be stored in the hidden file %UserProfile%\.ssh\known_hosts so that the next time you log in, you will not be prompted for it again.
Next, you must provide the password. Immediately after that, if all the information you provided is correct, you will be connected to the remote server to program or run system administration tools.
When you are finished, type “exit” to close the connection.
