From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have 4 servers. 3 on oracle cloud, and 1 on google. So i decided to setup guackamole with docker on one. I did everything, i added my private key, and tried to connect. But i got an error, and the same when i tried to connect from powershell (server sent public key). The key worked before. I tried to connect to the same server where guacamole is running from. I tought that oracle maybe regenerated the key, so i deleted the existing one, and regenerate it, but that failed too. But putty still works, i can still connect with it. Then i tried to use putty to regenerate the original key files, and that failed too. Then i cheked if the key on the server are still mached to the one i regenerated with putty, and they are the same. But i still can't connect. How can i fix this? I really don't know what went wrong.

Let me make sure I understand first

  1. You are attempting to passwordlessly SSH from Window to a group of servers using Powershell
  2. Something stopped working and you regenerated your Windows SSH keys

i added my private key, and tried to connect

This concerns me, as the server should have the user's public key, not private. Private should be exactly that, private

Is the Powershell user / SSH key the same as the Putty user / SSH key that still works?

When you run the Powershell script, does it give any error messages?

I know with Linux -> Linux SSH you can log verbosely with -v, is that something you can do under Powershell?

Is password auth enabled? Does that still work from Putty, and can you do the same from Powershell?

i added my private key

You are supposed to copy your public to the server, not the private one.
