xrdp doesn't work when started as a service, but works when started manually












0















Until recently, I had a working xrdp on my CentOS 7.4 workstation. I was able to connect from a Windows machine without any glitches. Then something changed (after a "yum update", maybe?), and I'm now unable to connect (symptom: "vnc error 1 after security negotiation"). I browsed through the logs trying to understand what was happening without much success.



Then, I tried to start xrdp and xrdp-sesman manually (with the -n "no-daemon" flag) on my workstation to get some "live" logs.



Surprisingly (?), when both are started manually I can then reach my machine through xrdp again.



Any idea of the tracks I might explore to fix my problem? You can find zillions of post related to xrdp / vnc / CentOS on the web, most with outdated information, and none were very helpful.



I think that the fact it works when started manually should trigger some flags, for Linux aficionados.

          Had exactly the same problem in Debian 9, and found the solution here:



          https://github.com/neutrinolabs/xrdp/issues/847



          See the comment just over 1/2 way down from imc0. Implementation for me required some modification. All my scripts (startwm.sh - not startwm-bash.sh - and the startwm-local.sh that I created) are in /etc/xrdp/, along with sesman.ini.



          Edited in response to comments:



          --> in /etc/xrdp create a file named startwm-local.sh
          which contains:



          #!/bin/sh



          exec dbus-launch --exit-with-X11 /etc/xrdp/startwm.sh



          --> run chmod ugo+x /etc/xrdp/startwm-local.sh



          --> edit /etc/xrdp/sesman.ini, and change the lines that read:



          UserWindowManager=startwm.sh



          DefaultWindowManager=startwm.sh



          to:



          UserWindowManager=startwm-local.sh



          DefaultWindowManager=startwm-local.sh
