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 work with a client that migrated their infrastructure to Microsoft. In order to connect to their Linux Server, I now have to Remote Desktop to their Azure Virtual Desktop thing. I'm not pleased but it's out of my control.

I tried remmina freerdp but doesn't seem to support that Azure thing, there doesn't seem to be an option to add the workspace.

Any recommendations or do I have to setup a virtual machine just for this? :/ Cheers

I wasn't able to set up a reverse tunnel, because I'm also under a corporate VPN :( I was able to get xfreerdp to work, though! Maybe I can add some port-forward + tunnels and be free :P

If your local machine is not reachable from the internet, you could set up the cheapest VPS - you can get a free one for 12 months at https://azure.microsoft.com/en-us/free/#all-free-services Connect from your destination machine (the firewalled one) to the VPS, and set up a reverse tunnel. For example, drop this into your ~/.ssh/config on the destination machine:

Host rtun
        Hostname something
        RemoteForward 1234 localhost:22

tmux new-ses 'while sleep 1; do ssh rtun; done'

Then configure your local machine to connect to destination via the jumpbox:

Host vps
        Hostname something

Host destination
        Hostname localhost
        Port 1234
        ProxyJump vps

ssh destination should work now.

Make sure to use SSH key auth, not passwords, and never transport secret keys off-machine. It's easier to wipe and recreate a VPS, if you lose keys, than to explain to Security folks how you were the donkey that enabled the breach.
