RDP to amazon EC2 Ubuntu instance

  • 772

I've set up an Amazon EC2 instance. I allowed RDP from any ip in the security groups, installed and started xrdp and added a user with a new password.

However when I try to remote connect, the connection simply fails.

Does anyone have any experience with this that could point me in the right direction?

Edit: How I set it up

sudo aptitude update
sudo aptitude install ubuntu-desktop 
sudo aptitude install xrdp
sudo /etc/init.d/xrdp start
sudo adduser USERNAME
sudo adduser USERNAME sudo

Then I set my EC2 Security group to be:

Type        Protocol    Port Range  Source
All TCP     TCP         0 - 65535   0.0.0.0/0
SSH         TCP         22          0.0.0.0/0
HTTP        TCP         80          0.0.0.0/0
RDP         TCP         3389        0.0.0.0/0
All ICMP    All         N/A         0.0.0.0/0

Edit 2: More details, for Yaron

I have not set up iptables. My netstat output, with my ssh hostname changed

  1. In order to connect to an EC2 instance you'll have to configure a public IP and make sure you add a matching routing table rule.

    There are 2 ways of getting a public IP:

    1. Adding a randomly selected IP during the instance set up (just tick the required V on the third screen).
    2. Adding an Elastic IP from the Elastic IP section on the left (this method does not require a new machine, you can attach this IP to your machine with no hassle).

    Now you'll need to configure the routing table.

    First go to the VPC section, click the Internet Gateway link and add a new gateway attached to your VPC.

    Now click the Routing Tables link and add a routing table rule to forward the traffic to 0.0.0.0/0 to this igw (the list will pop up and this will probably be the only option).

    Good luck, Yaron.
