2020-3-19 Thank you for writing to Microsoft Community Forums. I understand that you are facing issues while connecting to Ubuntu client using Windows Remote Desktop connection. In order to connect to remote desktop session on an Ubuntu machine you need to install XRDP server on Ubuntu first. 2020-1-7 可以使用 Microsoft 远程桌面客户端，通过几乎任何设备从几乎任意位置连接到远程电脑和你的工作资源。You can use a Microsoft Remote Desktop client to connect to a remote PC and your work resources from almost anywhere using just about any device.

Linux virtual machines (VMs) in Azure are usually managed from the command line using a secure shell (SSH) connection. When new to Linux, or for quick troubleshooting scenarios, the use of remote desktop may be easier. This article details how to install and configure a desktop environment (xfce) and remote desktop (xrdp) for your Linux VM using the Resource Manager deployment model.

Prerequisites

This article requires an existing Ubuntu 18.04 LTS VM in Azure. If you need to create a VM, use one of the following methods:

The Azure CLI
The Azure portal

Install a desktop environment on your Linux VM

Most Linux VMs in Azure do not have a desktop environment installed by default. Linux VMs are commonly managed using SSH connections rather than a desktop environment. There are various desktop environments in Linux that you can choose. Depending on your choice of desktop environment, it may consume one to 2 GB of disk space, and take 5 to 10 minutes to install and configure all the required packages.

The following example installs the lightweight xfce4 desktop environment on an Ubuntu 18.04 LTS VM. Commands for other distributions vary slightly (use yum to install on Red Hat Enterprise Linux and configure appropriate selinux rules, or use zypper to install on SUSE, for example).

First, SSH to your VM. The following example connects to the VM named myvm.westus.cloudapp.azure.com with the username of azureuser. Use your own values:

If you are using Windows and need more information on using SSH, see How to use SSH keys with Windows.

Next, install xfce using apt as follows:

Install and configure a remote desktop server

Now that you have a desktop environment installed, configure a remote desktop service to listen for incoming connections. xrdp is an open source Remote Desktop Protocol (RDP) server that is available on most Linux distributions, and works well with xfce. Install xrdp on your Ubuntu VM as follows:

Tell xrdp what desktop environment to use when you start your session. Configure xrdp to use xfce as your desktop environment as follows:

Restart the xrdp service for the changes to take effect as follows:

Set a local user account password

If you created a password for your user account when you created your VM, skip this step. If you only use SSH key authentication and do not have a local account password set, specify a password before you use xrdp to log in to your VM. xrdp cannot accept SSH keys for authentication. The following example specifies a password for the user account azureuser:

Note

Specifying a password does not update your SSHD configuration to permit password logins if it currently does not. From a security perspective, you may wish to connect to your VM with an SSH tunnel using key-based authentication and then connect to xrdp. If so, skip the following step on creating a network security group rule to allow remote desktop traffic.

Create a Network Security Group rule for Remote Desktop traffic

To allow Remote Desktop traffic to reach your Linux VM, a network security group rule needs to be created that allows TCP on port 3389 to reach your VM. For more information about network security group rules, see What is a network security group? You can also use the Azure portal to create a network security group rule.

The following example creates a network security group rule with az vm open-port on port 3389. From the Azure CLI, not the SSH session to your VM, open the following network security group rule:

Connect your Linux VM with a Remote Desktop client

Open your local remote desktop client and connect to the IP address or DNS name of your Linux VM. Enter the username and password for the user account on your VM as follows:

After authenticating, the xfce desktop environment will load and look similar to the following example:

If your local RDP client uses network level authentication (NLA), you may need to disable that connection setting. XRDP does not currently support NLA. You can also look at alternative RDP solutions that do support NLA, such as FreeRDP.

Troubleshoot

If you cannot connect to your Linux VM using a Remote Desktop client, use netstat on your Linux VM to verify that your VM is listening for RDP connections as follows:

The following example shows the VM listening on TCP port 3389 as expected:

If the xrdp-sesman service is not listening, on an Ubuntu VM restart the service as follows:

Review logs in /var/log on your Ubuntu VM for indications as to why the service may not be responding. You can also monitor the syslog during a remote desktop connection attempt to view any errors:

Other Linux distributions such as Red Hat Enterprise Linux and SUSE may have different ways to restart services and alternate log file locations to review.
