Part 2: Install XRDP on CentOS 7

After XRDP is installed, you can start the service with the command:

systemctl start xrdp

XRDP will now listen on 3389. You can verify this with the following netstat command:

netstat -antup | grep xrdp

This results in the following output:

tcp 0 0 0.0.0.0:3389 0.0.0.0:* LISTEN 1508/xrdp
tcp 0 0 127.0.0.1:3350 0.0.0.0:* LISTEN 1507/xrdp-sesman

We would like to point out that the XRDP will not start automatically after a reboot. Hence, run this command to enable the service during system startup:

systemctl enable xrdp

Configure the firewall

The next step is to configure the firewall in order to permit RDP connections from external machines. Run this command to add the exception for the RDP port:

firewall-cmd –permanent –add-port=3389/tcp
firewall-cmd –reload

Configure SELinux

Run the following commands to configure SELinux:

chcon –type=bin_t /usr/sbin/xrdp
chcon –type=bin_t /usr/sbin/xrdp-sesman

Test XRDP Remote Connectivity

Next, let’s check the remote connectivity. First, take RDP on any Windows machine via Remote Desktop Connection. Then enter the Linux server’s IP address in the computer field and click connect.

Ignore the RDP certificate name mismatch warning.

Then enter the username and password. You can opt for the root or any user available on the system. Ensure you use the module Xvnc.

Once you click ok, you will obtain the desktop within thirty seconds.
