[solved] unable to connect RDP session to Ubuntu Server

Hello,

Let us look into it and we will get back to you.

Best regards,

Hello

From the log file you provided, NLA is properly configured. RDM attempts NLA first and if it fails, it falls back to TLS automatically (that's the "Enabling NLA security: FALSE" you see in the log). The actual error is further up in the log file - the NLA handshake is failing at some point as the server doesn't send a response that we are expecting.

Since this setup works with MS RDP, it should work with RDM too. However please note that the fact it works on RDM Windows doesn't tell much - RDM Windows is by default using the MS RDP client (ActiveX control) which sadly can't be embedded on other platforms.

I did try a quick test using an Ubuntu server in our lab with xrdp and NLA and it worked well. I think we need some more information on what your RDP server setup is (e.g. xrdp, gnome-remote-desktop, etc) and also the version you are using. Any relevant information you can provide will be helpful.

Please don't hesitate to post back if something isn't clear or you have further questions.

Thanks and kind regards,

Hi Richard

thank you for looking into it.

i use Ubuntu 22.04 with wayland , xrdp version is 0.9.17

I configured it only through the GUI and it uses only the defaults...

What else can i provide to help here?

with the Microsoft RD App on iOS it also works...

kind regards

Christoph

Hello again

Are you quite sure you're using xrdp? From some research on this issue, xrdp does not support NLA. In my test environment, it's working because it makes the fallback to TLS security. However, in your case the server is quite clearly telling that NLA is enabled _and_ required.

I don't believe xrdp has a graphical configuration, but you mentioned you configured via the GUI. Can you confirm if you did that through Settings > Sharing > Remote Desktop? If that's the case on Ubuntu 22, then I believe your server is probably Gnome Remote Desktop rather than xrdp.

Please let me know if that's accurate, obviously it would mean I need a different test setup on my side.

Thanks and kind regards,

One thing I forgot to ask - is your RDM iOS version up-to-date?

Thanks and kind regards,

you may be right. I installed xrdp but looking closer it seems to inactive.

I also have

gnome-remote-desktop/jammy-updates,now 42.7-0ubuntu1 amd64 [Installiert,automatisch]

and yes, it was made through „settings->sharing“

I‘m not very experienced with Ubuntu so I may have confused the configuration here…

RDM on my iPhone is Version 2023.2.3 so I assume latest

Kind regards

Christoph

Hi

Thanks for the follow up, I am also not very experienced with Ubuntu so I wanted to make sure we had everything square.

I need to see if I can reproduce this on my side, please allow a little time as I need to get a test environment setup. I appreciate your patience on that. I'll post back once I have an update.

In the meantime, please don't hesitate to post with further questions or issues.

Thanks and kind regards,

Hello again

I've been playing with this but I'm still unable to recreate your issue.

Can you tell me how you setup the server to require NLA? It's not an option that I see the GUI, but your server definitely wants it (as you saw by the HYBRID_REQUIRED_BY_SERVER in the logs).

Thanks and kind regards,

Hi Richard,

unfortunately I have no idea how I set that.

as mentioned I only configured by GUI…

I also don’t know how to disable it…

kind regards

Hello again

RDM iOS 2023.2.4 is being released currently, it however will take a few hours before it's available in the App Store.

Before going further, I'd appreciate if you can try with the newest version and, if the issue is not resolved, generate a new log file on that version.

It doesn't have a specific fix for your issue, but it does contain an update to our RDP module with a large number of bug fixes and changes.

Please let me know if something isn't clear,

Thanks and kind regards,

Hi Richard,

I really appreciate your effort to solve my issue.

unfortunately it still does not work with the new version.

log is attached....

kind regards

Christoph

for some reason I can only attach images here through my iPad...
