In the Link kvprasoon added, under Remoting over WSMan, it says the following:
for macOS/Linux -> Windows remoting scenarios, our goal is to enable existing remoting cmdlets (e.g. Enter-PSSession, New-PSSession, and Invoke-Command) using the traditional WSMan protocol. This currently works for basic authentication as well as for NTLM-based authentication from (only) Linux environments.
So if I understand it correctly, It should be able me to use Enter-PSSession command in order to gain access remotely from Linux to Windows.
What am I missing?
