# Python implementation without need for linux
# Send the IP address of your BambuLab printer to port 2021/udp, which BambuStudio is listens on.

# Ensure your PC has firewall pot 2021/udp open. This is required as the proper response would usually go to the ephemeral source port that the M-SEARCH ssdp:discover message.
# But we are are blindly sending a response directly to the BambuStudio listening service port (2021/udp).

# Temporary solution to BambuStudio not allowing you to manually specify the Printer IP.

 <#
.SYNOPSIS
  Configures a secure WinRM listener over HTTPS to enable
  SSL-based WinRM communications. This script has not been
  tested on Windows Server 2003R2 or earier, and may not
  work on these OSes for a variety of reasons.

  If Windows Remote Management is disabled (e.g. service
  stopped, GPO Policy, etc.), this script will likely fail.

Here is a simple method to fix Ruby 2.3.x OpenSSL connectivity errors (on Windows) when trying to install gems via rubygems. This method is the cleanest way to solve the problem and does not rely on you disabling any secure/https connectivity options in Ruby. Essentially, you are adding the missing CA certificate into the Ruby ssl_certs directory to complete the chain of trust.

Sample error messages:

*::Error::ConnectionFailed SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

or:

connect_nonblock': SSL_connect returned=1 errno=0 state=error: certificate verify failed (OpenSSL::SSL::SSLError)

Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface.
You can use the user and password that you use for the web interface.

You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS.
You don't need to install it, just extract it or copy the files in "jre" folder.

Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor.
Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture.
Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs.
