I require to install xrdp for remote desktop access of my linux server (RHEL 7.3).I searched a lot for it in google, but not able to find any suitable package for the same.One post I have found where the server where I am need to connect the server in Internet.But it is not possible for me to connect the server in Internet. How can I install and configure xrdp successfully with out internet connection in the server?Can some body share some link for package and procedure to install?
What? Linux and no Internet??

Honestly, you can download on another computer with a Web browser.
