 ## Accessing the cluster:
 
 You can use the ssh key specified during the launch of the stack to access any VM with the "centos" username.
 
 ```
-ssh centos@<ip>   # <ip> can be the public IP or the private IP of the controller/compute VM, both work
+ssh -i <ssh-key name> centos@<ip>   # <ip> can be the public IP or the private IP of the node
 sudo -s
 ```
-**Accessing the Contrail webUI:**
-
-```
-https://<controller-public-ip>:8143      admin / contrail123
-```
-
-**Accessing the Kubernetes dashboard:**
-
-On the controller:
-
-```
-kubectl get pods -n kube-system -o wide | grep dashboard
-```
-
-Check the IP column. It tells you the private IP address of the compute node where the dashboard POD is running. You need to find out the associated public IP address (it is left to you as an exercise). Once you know it, you can connect to the URL:
-
-```
-https://<public-ip>:8443
-```
-
-Select the token option. Where can you get the token from? There is one on the controller’s file /root/k8s_dashboard_token.txt , but it only allows to visualize. If you want read-write access do the following:
-
-```
-kubectl get secret -n contrail | grep kubemanager
-kubectl describe secret <name> -n contrail | grep "token:" | awk '{print $2}'
-```
+The sandbox interface will provide information about how to connect to Tungsten Fabric UI and Kubernetes dashboard.
 
-Take your time to browse the dashboard. During the next exercises, you can choose to do some tasks on the web instead of (or in addition to) the CLI.

 ## Appendix: IAM Users
 
-If, instead of using a root account, you are signing with an IAM user, you need to grant additional privileges for the user.

 - Log on to the AWS console.
-- In the AWS services search at the top left of the console, look for IAM and select it.
-- On the left navigation bar, click on the user whose privileges you need to change.
-- At the right bottom, click Add inline policy.
-- Go to the JSON tab, and replace the content with the following policy:
