Centos 7 xrdp tigervnc - VNC Error - some Problem

Post by BGood » 2017/10/27 01:40:46

This old problem reappeared after upgrading from Centos 7.1 to 7.4. Connecting from Windows 7 Remote Desktop into Centos 7.4 server through the LAN results in the 'VNC error - problem connecting' 'some problem' error message.

I used to be able to connect through RDP with the MATE Desktop, but after the latest Centos upgrade I can't do this anymore. I tried disabling the graphical interface on the server's main console and this does not seem to help. The [xrdp1] stanza of my /etc/xrdp/xrdp.ini looks like this:

Code: Select all

[xrdp1]
name=sesman-Xvnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=-1
xserverbpp=24
delay_ms=2000
And the /var/log/xrdp.log of my attempted connection looks like this:

Code: Select all

Can anyone tell from the VNC error messages how to fix this? Thanks for any guidance!
