How to connect it at web?

[allran]

Is it any way to use client at web? For example, use mstsc.js, node-rdpjs, or other. Thanks!
I use mstsc.js, and can't connect. When i use [Microsoft Remote Desktop], and can connect ubuntu with xrdp success.

xrdp provides a standard RDP server. You can connect to it with any valid RDP client.

I can't tell you how to use any of the JavaScript alternatives you've linked to - you'll need to ask their own user communities.

If you just want to connect from a web client, I suggest you look at installing Apache Guacamole on your server, and then just connecting over https. That is known to work well with xrdp.
