Multiple RDP Bastion connections

Hamzeian, Donya 20

I have created an Ubuntu 20.04 virtual machine. On this VM I have 2 users. User1 is an admin and User2 is a sudo level user. I followed these steps to install xrdp on the VM https://learn.microsoft.com/en-gb/azure/virtual-machines/linux/use-remote-desktop?tabs=azure-cli
Now, User1 is able to connect to the VM using Bastion Protocol RDP and Port 3389. However, User2 is only able to connect through Bastion SSH. I need multiple people to connect to the VM through Bastion RDP at the same time. Note that I have configured the Bastion to "Standard" with 3 instances.

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to have multiple concurrent RDP sessions to your Linux VM using xrdp Service and Azure Bastion.

As stated by Silvia Wibowo, this could be a limitation from the service you are using.

The best way to check this is,

Use a normal RDP from a VM in the same subnet/VNET (using Private IP) with multiple accounts at the same time

Both user1 and user2.

If this does not work, then we can finalize that the third party RDP Service is not accepting multiple connections.

Can you please check the above and let me know the results?

Cheers,

Kapil

The answer from Azure portal support team:

Run these commands in the terminal:

sudo usermod -aG ssl-cert User1

sudo usermod -aG ssl-cert User2

Those added both user to the xrdp file. Note, that command was used in the CLI of first user.

Then execute this command:

echo xfce4-session >~/.xsession

That one still in the first user CLI then go and change to the second user 'User2' and run the command again there.
Then run the command to restart xrdp and finally, restart the VM.

Hi @Hamzeian, Donya , I understand that you've installed xrdp on Ubuntu Azure VM then connect to it via Azure Bastion with RDP protocol. You found that only User1 can login via RDP.

I believe there is default setting in xrdp, controlled by /etc/xrdp/sesman.ini that you can modify.

I'm glad that you were able to resolve your issue and thank you for posting your solution so that others experiencing the same thing can easily reference this!

Since the Microsoft Q&A community has a policy that "The question author cannot accept their own answer. They can only accept answers by others", I'll repost your solution in case you'd like to "Accept" the answer.

Issue:

Configure multiple concurrent RDP sessions to Linux VM using xrdp Service and Azure Bastion.

Solution:

You contacted Azure Support team and they suggested the following.

Run the below to add users to the Group

sudo usermod -aG ssl-cert User1

sudo usermod -aG ssl-cert User2

Then execute this command individually in the shells of both users:

echo xfce4-session >~/.xsession

Then run the command to restart xrdp and finally, restart the VM.

Thanks,

Kapil
