How To Use Network Tools Application For Connectivity Test From CloudHub Virtual Private Cloud (VPC)

In order to deploy the MuleSoft Network Tools application, perform the following:

• Download the application in the attachments section at the bottom of the page
• Follow the instructions below and replace the default credentials.
• Stop your net-tools app when you don't need it.

Prerequisite:  

• You will need an Anypoint account to deploy your application. Talk to your organization admin to create one for you if you are a customer, or sign up for a trial account
• Before you go on with the next steps, please familiarize yourself with the below topics
  • VPC
  • CloudHub Networking Guide
• (Optional) Open the project and check for details
  • Download Anypoint Studio 7 
  • Setup Anypoint Studio

Deploy the application to CloudHub

1. Make sure the environment(s) are associated with the VPC. You can verify this by

   • Log into to Anypoint Platform with your account
   • navigate to Runtime Manager
   • Click on VPCs
   • Select the VPC from which you want to test the connectivity
   • Make sure the environment you are going to deploy the application appears in the "Environments" tab of the VPC

2. Deploy to the CloudHub

• Switch to the environment and click the applications tab
• Click "Deploy applications"

• Make sure it's in the right environment and in the same region as the VPC
• Name the application. Since the name is in a global naming space, please give it a unique name 
• Deploy Target is CloudHub
• Choose the Runtime Version >= 4.4.0
• 0.1 vCore is enough for the test
• 1 worker

• Switch to the "Properties" tab. Specify the username and password here by "user=<your username> and pass=<your password>" otherwise you will be using the default one "vpc-tools:SomePass"

• When your application is fully deployed (it may take a few minutes), grab the Domain name from the console
• Put the Domain name in a browser and log in

• Ready to test the connectivity

Test tools available in the network tools with CloudHub

Certificates

1. Ping (only available on Cloudhub 1)

   Run the command "ping -c 4 <IP Address or Host>" on the network tools worker  

2. Traceroute

   Run the command "traceroute -w 3 -q 1 -m 18 -n <IP Address or Host>" on the network tools worker  

3. Socket

   Try to get a socket connection to <IP Address or Host> on <Port> with "socket.connect" method, equivalent to establishing a three-way TCP handshake connection. This is used to test TCP connectivity and measure TCP latency. It will run the test 5 times.

4. DNS

   Try to resolve the <IP address or Host> and return the IP. You can now specify a DNS server of your choice. This is useful to test if the DNS servers are reachable and work as expected before changing your VPC's default DNS servers.

5. cURL

   Run the command "curl -k -E -i -L <IP Address or Host>:<Port>/<Path>". Note that please add HTTP or HTTPS to the <IP Address or Host> and remove "/" at the beginning of <Path>

6. Certificates

   Establishes a TLS connection to a given TLS/SSL endpoint and pulls any certificates presented by the endpoint.

7. Ciphers

   This test runs several TLS connections against a given TLS/SSL endpoint changing the offered cipher suites to find out which ciphers are supported by the endpoint.

Known Issues/Functional Limitations with CloudHub 2.0

When using the Network tools in CloudHub 2.0 private spaces, the Ping command is not supported, as part of a security enhancement; Ping is now forbidden and errors may occur in the browser console:

When using the Network tools using HTTP, the following errors may occur in the browser console:

Refused to execute script from 'https://${url}/js/jquery.min.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Refused to execute script from 'https://${url}/js/toastr.min.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
