Simple way to get RDP into Ubuntu AWS box:
- Create the instance in the EC2 Management console and enable incoming RDP in Security Groups
- Create a new user with a password
- Add the new user to the sudoers file and copy over the AWS server’s public key
- Log in as the new user and install xrdp
- Load Remmina on your local machine and open a new RDP connection
In EC2 Management Console, click on the instance you want to connect to and scroll the page to the right. There will be a URL link to the relevant Security Group configuration page. Click on the Inbound tab and then the Edit button. Add a new rule, look for RDP as the type and set anywhere as the source (or make it specific if you want).
Move to the Terminal on your local machine and login to your AWS server with a command similar to:
LocalMachine:$ ssh -i ~/AWS-keypair.pem firstname.lastname@example.org
Create new user e.g. george
AWSMachine:$ sudo adduser george
Follow the prompts to enter the password and other optional user information. Add the new user to the sudoers file using the visudo command:
AWSMachine:$ sudo visudo
Add the following line after the comment line, “User privilege specification” and save the file.
george ALL=(ALL:ALL) ALL
Ensure that the user george is in the sudo groupusing:
AWSMachine:$ sudo adduser george sudo
The new user account cannot be accessed (e.g. via SSH) until the public key from the AWS instance’s key pair (the .pem file) is installed for the new user. To do this, copy the public key installed for the ubuntu user and paste it into the correct file in the new user account. The public key can be found in the file ~/.ssh/authorized_keys under the ubuntu account.
AWSMachine:$ cat ~/.ssh/authorized_keys
SThe command above will print the public key. Select everything apart from the name of the key pair at the end of the key and copy it.
Next, switch to the new user account, george, and make sure you are in the home directory.
AWSMachine:$ sudo su george
Create the SSH directory and authorised users file, with the correct permissions in the home directory. Then edit the authorized_keys file with a text editor.
AWSMachine@george:$ mkdir .sshAWSMachine@george:$ chmod 700 .ssh AWSMachine@george:$ touch .ssh/authorized_keys AWSMachine@george:$ chmod 600 .ssh/authorized_keys AWSMachine@george:$ nano .ssh/authorized_keys
Paste in the public key you previously copied and save the file, before exiting the system.
AWSMachine@george:$ exitAWSMachine:$ exit
You should now be able to log into the new user george on the remote Amazon AWS server using the same keypair. On your local machine, use the SSH command:
LocalMachine:$ ssh -i ~/AWS-keypair.pem george@
We now are logged in as user george.
Install the lxde lightweight desktop manager and start it.
sudo apt-get update sudo apt-get install lxde sudo start lxdm
Also install xrdp to establish a remote desktop connection.
sudo apt-get install xrdp
Remote desktop connections require a username and password. The username will be george and the password will be the one set when the user was created. If you forget this the password can be reset using:
sudo passwd ubuntu
None of this would be known without the notes and guidance from others on the web, namely:
