Connect to Ubuntu 18.04LTS server via xrdp

Question

EDIT I was having user/pass issues. Now they are solved, and I found another problem.

I mean to connect for the first time to an Ubuntu 18.04 LTS server via xrdp from Win 10. I can already connect with vino-sever and tigervnc client. I connect via VPN.

I followed this, but when connecting via xrdp I do not get the Authentication Required dialog mentioned in the link, step 3. Instead, I get

How can I fix this issue?

Do I have to kill vino-server, or can they both be active simultaneously?

Do I have to enable RDP port 3389? How? I guess this is ok, since when the xrdp window is open, I see

$ sudo netstat -antup | grep xrdp
[sudo] password for myuser: 
tcp6       0      0 ::1:3350                :::*                    LISTEN      15449/xrdp-sesman   
tcp6       0      0 :::3389                 :::*                    LISTEN      15460/xrdp          
tcp6       0      0 xx.xx.xx.xxx:3389       xx.xx.xx.xxx:61469      ESTABLISHED 15869/xrdp

and when I close it, I see

$ sudo netstat -antup | grep xrdp
[sudo] password for myuser: 
tcp6       0      0 ::1:3350                :::*                    LISTEN      15449/xrdp-sesman   
tcp6       0      0 :::3389                 :::*                    LISTEN      15460/xrdp

why don't you stop the others and try connection with xrdp alone and see what happens? — George Udosen, Mar 13 '20 at 08:37
And of course if your connection via port 3389 then that port aught to be open on the server! — George Udosen, Mar 13 '20 at 08:43
@GeorgeUdosen - How do I check if port 3389 is open, and open it if not? — sancho.s ReinstateMonicaCellio, Mar 13 '20 at 08:55
where is this server hosted? Nonetheless check your firewall rules, if you didn't create one then it's not done automatically but check — George Udosen, Mar 13 '20 at 08:58
@GeorgeUdosen - Server hosted at a local company (I do not know if this answers the question). Still I am not sure how to check if port 3389 is open. As for the firewall, I guess this means it is no problem: $ sudo ufw status verbose `Status: inactive` — sancho.s ReinstateMonicaCellio, Mar 13 '20 at 09:41

@GeorgeUdosen - 1. Machines not at the same place, now. 2. Please see updated OP (header). — sancho.s ReinstateMonicaCellio, Mar 13 '20 at 10:39

There is no enough information in your question to provide a 100 % working solution... Your issue is probably related to the fact that you are running an not up to date Ubuntu 18.04 version. We are guessing that you are running Ubuntu 18.04.2.

As described in this post, in Ubuntu 18.04.2, the xorgxrdp package does not get installed because of missing dependencies....

To fix your issue, you have multiple options

Option 1

use the easy to use xrdp-installer-v1.1.sh script that will detect and fix the possible missing dependencies. Please read the info provided in the post to learn how to use the script properly...

Option 2

Upgrade your Ubuntu 18.04.x with the latest updates (which will bring your Ubuntu to 18.04.4) and remove/install the xrdp package manually using the following command

sudo apt-get install xrdp 

sudo apt-get install xorgxrdp-hwe-18.04

Note : To check which version of Ubuntu you are running, from a terminal console, you can issue the following command

lsb_release -a

Hope this help

Till Next Time

See Ya
