Remote Desktop from Win 7 to Centos 7.4 broken: xrdp/tigervnc-server

Post by BGood » 2017/10/18 21:28:59

After upgrading my Centos 7.1 minimal server to Centos 7.4 I can no longer connect from Windows 7 Remote Desktop to the Centos 7.4 server over the LAN. The MATE Desktop works fine from the server console, and Putty works fine over the LAN, but when I try to connect with Windows Remote Desktop there is no response from the Centos server and Remote Desktop eventually times out. On the other hand, Windows Remote Desktop connects fine with my Windows Server 2008 R2 on the same LAN and I can ping the Centos server's eth0 from the Windows terminal.

Using Wireshark to sniff network traffic while attempting the connection, I can see outgoing request to the Centos 7.4 server, but nothing coming back. I have tried installing and re-installing the following packages but have not made any progress:

yum install xrdp tigervnc-server -y
chkconfig --levels 35 xrdp on
service xrdp start
systemctl enable xrdp

My /var/log/xrdp-sesman.log looks like this:
[20171018-14:56:41] [DEBUG] libscp initialized
[20171018-14:56:41] [INFO ] starting xrdp-sesman with pid 1111
[20171018-14:56:41] [INFO ] listening to port 3350 on

I vaguely remember previously having to install an earlier version of tigervnc, but do not recall exactly what version it was.

Does anyone have any suggestions? Thanks
