Step 1) The first step is to make sure that the OpenSSH Client and Server features are not already installed.
#Openssh windows windows#
In this blog, I will walk you through the steps of configuring the OpenSSH Server and Client packages on Windows Server 2019 Standard and using WinSCP to copy files to a remote Windows server.
#Openssh windows windows 10#
While Windows lacked native SSH support for the longest time, as of Fall 2018, Microsoft added native support for OpenSSH Server and OpenSSH Client starting with Windows Server 2019 and Windows 10 Build 1809. When the client connects to the server for the first time, the public host key is passed on to the client. The server host key is used primarily to ensure that the client is really communicating to the right server. A single key can be shared across multiple hosts, in any event, each host should have at least one key. Each host can have multiple keys that are generated using different algorithms.
When the OpenSSH-server package is installed, the host key is automatically generated and stored in /etc/ssh. Another SSH security feature that I find lacking in Windows is the concept of a host key. It then switches to symmetric encryption to bulk encrypt the TCP traffic between the client and the server using that key. SSH uses asymmetric encryption, which does not require a shared secret key to establish a shared secret key. Unlike Telnet, which does not encrypt client-server traffic, SSH traffic is fully encrypted, thereby making it the de-facto standard for accessing remote servers. The only port that needs to be opened on the server is Port 22, which is the default port assigned by the Internet Assigned Numbers Authority (IANA).
It works just as well even when the servers are hosted in the cloud. Personally, I find WinSCP quite helpful as it allows me to transfer files back and forth from my Windows desktop machine to any of the Unix/Linux hosts that I manage. Those of you who work with Linux and Unix servers are quite familiar with open-source SSH tools such as Putty and WinSCP. The SSH server daemon allows users to securely connect to Linux and Unix servers using an SSH client.
Having worked with Unix and Linux servers for a long time, one feature that I came to appreciate is the Secure Shell (SSH) daemon.
