I would like to know if its possible to write an powershell script that connects to an Server via ssh and then do something on that server.
Thank you for your help.

That is a very abstract question. the answer is that you can make a call via ssh, and run a (non-interactive) command via powershell/batch file, but you need a third party SSH client AFAIKJoSSte– JoSSte2018-10-28 18:55:06 +00:00Commented Oct 28, 2018 at 18:55

Concret I have a raspberry its used for streaming music. There are two softwares installed. One for Apple (Airplay) and on is just for simulating a Spotify connect Device. I need a script that connects to the raspberry via ssh. It the should increase the volume with alsamixer.H.Kümmel– H.Kümmel2018-10-28 18:57:36 +00:00Commented Oct 28, 2018 at 18:57

1Sure, you need a ssh client you can use on the command line, some are available, most prominent is the openSSH client, but also PuTTY comes with a command line executable. You can call that executable from your script and specify an option that allows to specify a script to be executed on the remote site. However you can not execute a powershell script on the server side, since that most likely is a Linux system, so unixoid. An ssh server on a MS-Windows systems is totally exotic and you can use powershell only on that system, other operating systems offer far better shell solutions.arkascha– arkascha2018-10-28 18:58:41 +00:00Commented Oct 28, 2018 at 18:58

There are many articles all over the web on this topic, and since PowerShell Core is now Open Source and can be installed on Windows / Linux / OSX the SSH for PowerShell has been an thing for a while now.
Example(s):
Using SSH to Access Linux Servers in PowerShell
Managing Windows Powershell from Linux terminal
There a several module on the MS PowerShellGallery specifically for this use case.

I was about to suggest that you use PuTTY. in fact, you should be using plink
If you look at SSH (the command for Linux), you can execute remote commands in this fashion:
Single command:
ssh $HOST ls
Several commands:
ssh $HOST ls; pwd; cat /path/to/remote/file
If you want to do this on a windows machine, you either need to use plink.exe or a similar tool.
Apparently there is also some library for powershell to execute remote commands via ssh, but this is the result of me spending 30 seconds to google remote command ssh powershell so I do not know if it will work for you, or if it requires powershell on the remote (you can get it for linux)
