Ubuntu – WSL2 Remote Desktop Can’t connect to the remote computer for one of these reasons

I think that the xrdp.ini parameter that controls the listening interface IP is called 'address' not 'ip' i.e. in the globals section:

[globals]
address=127.0.0.1

At least, this works for me - however note that I am using a source-built xrdp from http://scarygliders.net/x11rdp-o-matic-central-downloads-page/ so I can't guarantee it is supported in the default packaged version.

The closure of the port can be confirmed by running netstat on the remote host, or using nmap i.e. before adding 'address=127.0.0.1' to the [globals] section:

$ sudo nmap -p 3389 192.168.1.16

Starting Nmap 5.21 ( http://nmap.org ) at 2013-08-05 02:08 UTC
Nmap scan report for 192.168.1.16
Host is up (0.0065s latency).
PORT     STATE SERVICE
3389/tcp open  ms-term-serv

After adding the 'address' parameter and restarting the service

$ sudo nmap -p 3389 192.168.1.16

Starting Nmap 5.21 ( http://nmap.org ) at 2013-08-05 02:10 UTC
Nmap scan report for 192.168.1.16
Host is up (0.030s latency).
PORT     STATE  SERVICE
3389/tcp closed ms-term-serv

Also note that at least in Windows 7, the native Remote Desktop Connection client appears to have trouble if the remote server is tunneled to localhost:3389 (the default xrdp port), I ended up setting my putty tunnel as

L33389    localhost:3389

and then specifying localhost:33389 in the Remote Desktop Connection dialog (although any suitably high numbered free port should work as well)

I had a similar issue.. to get it working for me I edited my xrdp.ini by runing

sudo gedit /etc/xrdp/xrdp.ini

then added the below to the list for my set up:

[xrdp8] 
name=Reconnect 
lib=libvnc.so 
username=ask
password=ask
ip=127.0.0.1 
port=5910

I assume yours would be the same but with port=5900

I first log in to my machine usung the default sesman-Xvnc connection option in the 'Login to xrdp' 'Module' drop-down list..

This creates the original session that i can then log back into later by selecting the Reconnect option i have created which should now show in the 'Login to xrdp' 'Module' drop-down.

All my open programs, windows and files are just as i left them in the first session when i log back in using this..

I can access this same session again from any of my other Windows PC's Remote Desktop Connection clients by again selecting Reconnect in the Xrdp login 'Module' drop-down.
