Ever want to confirm that a port is accessible from one computer to another? There’s a PowerShell cmdlet for that, Test-NetConnection. With the -Port option, this cmdlet will do a quick TCP three-way handshake on the remote system to confirm that the service is available and reports back if it succeeded or not. Check out that last line of output TcpTestSucceeded: False. That indicates that this port is not accessible. You can see, however, that the system is reachable via ICMP (Ping), PingSuceeded: True so we know that the remote system is alive, just not listening on the port we want to access.
I’m proud to announce the completion of my first Pluralsight Learning Path. This learning path is built to advance your Linux knowledge to the system administrator or system engineer level. In this series of courses you’ll learn the theory behind how things work and also practice demonstrations and tips to really nail home the things you need to know to run production Linux systems. The learning objectives of this series align with the Linux Foundation Certified Engineer (LFCE) certification “Domains and Competencies” however these courses will be very valuable to your development as a Linux professional even if you’re not interested in certification.
So in yesterday’s post we learned that the OpenSSH client is included with the Windows 10, Update 1803! Guess, what else is included in this server, an OpenSSH Server! Yes, that’s right…you can now run an OpenSSH server on your Windows 10 system and get a remote terminal! So in this post, let’s check out what we need to do to get OpenSSH Server up and running.
First, we’ll need to ensure we update the system to Windows 10, Update 1803.
Today is a big day! The OpenSSH client version 7.6p1 is now part of the Windows 10 operating system! Microsoft released Windows 10 Update 1803 and included in that release is the OpenSSH client, which is installed as part of the update.
That’s right an SSH client as part of the Windows operating system by default! Also included with this update is the OpenSSH Server which is included as an Windows Feature on Demand.
Folks in the Linux world are used to moving SSH keys to and from systems enabling password-less authentication. Let’s take a minute to look at what it takes to use PowerShell to distribute SSH user keys to remote systems.
In the OpenSSH package there’s a command ssh-copy-id which is a bash script that copies a user’s public key to a remote system. There’s a little intelligence in the script to set things up properly on the remote system for password-less key based authentication.

This year I have two sessions!
On Tuesday, April 10th at 2:00PM – I’m presenting “OpenSSH Internals for PowerShell Pros”
So I’ve been using dbatools for automated restore tasks and came across a SQL Server Agent job that I wrote that was reporting success but the job was actually failing.
What I found was the function I used, Restore-DbaDatabase, was not able to access the path that I was trying to restore databases from. The Restore-DbaDatabase function, and all dbatools functions according to the dbatools team on Slack, will throw a Warning rather than an Error by design.
In our previous post we discussed how to implement OpenSSH (the plumbing) as the transport layer for PowerShell remoting. In this post, we’re going to leverage that configuration and look at some common remoting use cases. This is one of the core things I use everyday when I work with PowerShell. Remoting gives me the ability to administer scale up and administer large collections of systems. So like I said in my very first post about my PowerShell journey, it’s become a part of my every day life and techniques like this are at the core of how I use PowerShell.
So in my last post I told you about how I started my journey on learning PowerShell, let’s keep going down that path together. In this post I’m going to introduce PowerShell Remoting in Multi-Platform Environments, specifically using OpenSSH. We’ll discuss WinRM in multi-platform systems in an upcoming post.
Have you ever had to execute a command against one system or a collection of systems? Have you ever wanted a remote shell on a Windows system?
