How can I test network connectivity?

How can I test network connectivity?

Use a Laptop. 

 

It is recommended that you test network connectivity to the Qualys Cloud 

Platform using your laptop (or other device): 

1) Take the laptop to the location where the Scanner Appliance will be installed and 
connect the laptop to the network, using the same network cable and port that will be 
used for the Appliance.

2) Configure the laptop with the same network configuration that the Scanner Appliance 
will use (IP address, gateway, DNS server, etc.).

3) If the connection to the Qualys Cloud Platform must pass through a proxy server, 
configure the laptop’s web browser with proxy information.

4) Open a browser and try to log into your Qualys account. You’ll see the Qualys 

 

Log In

 page after a successful connection is made to the Qualys Cloud Platform.

Test DNS Name Resolution

.  You can test DNS name resolution from any machine 

connected to the same network as your Scanner Appliance. If DNS name resolution is 
working properly, server information is returned including the server name and IP 
address. (Note that “nslookup” is not available on all systems.)

Communication Failure message

You’ll see a 

COMMUNICATION FAILURE

 message if there is a network communications 

breakdown between the Scanner Appliance and the Qualys Cloud Platform. 

Why does it happen?

The communication failure may be due to one of these reasons: the network cable was 
unplugged from the Scanner Appliance, the local network goes down, or any of the 
network devices between the Scanner Appliance and the Qualys Cloud Platform goes 
down.

When does the message appear?

If there are no scans running on the Appliance - The next time the Appliance sends a 
polling request to the Qualys Cloud Platform, the polling request fails, and then the 

COMMUNICATION FAILURE

 message appears.

If there are scans running on the Appliance - The 

COMMUNICATION FAILURE

 message 

appears after the running scans time out. Usually the S1 LED turns off after the scans 
time out. If this message appears, it is recommended that you use the Qualys user 
interface to cancel any running scans and restart them to ensure that results are 
accurate.
