scripting language PowerShell under an opensource license (MIT) but I completely missed that they were providing a repository and ready to use packages for your favorite distribution.
Anyway an apt-get away and that's it:
New-Object net.sockets.tcpclient("libera.cc", 80) opens a TCP connection to a target host, a quick way to test if a port is open ( look for Connected: True for a successful socket creation)
