Running a Host Name Lookup Using the Network Test Tool in the Command Line

You can use the tool to perform a host name lookup and retrieve the network interface information of a client.

During the lookup request, the tool uses the following lookup methods on the target client:

  • DNS (Domain Name Service) lookup

  • Host file lookup

  • Forward and reverse lookup

Before You Begin

If you plan to run the tool on a Macintosh client, run the following command before using the tool:

export DYLD_LIBRARY_PATH=/opt/Software_Installation_Directory/Base

Procedure

From the command prompt, go to the Software_Installation_Directory/Base directory, and then run the following command:

CvNetworkTestTool -lookup -HostName hostname -log location

Where:

  • -lookup looks for the target client by using lookup methods, such as DNS and host file lookups.

  • -HostName specifies the host name or IP address of the target client.

  • (Optional) -log specifies the location of the log file. If you want to redirect the output to a separate file, specify the following: -log Log_Location > OutputFile_Location.

Examples:

  • On Windows:

    CvNetworkTestTool -lookup -HostName myclient.mydomain.com -log C:\lookup.log
  • On UNIX, Linux, or Macintosh:

    ./CvNetworkTestTool -lookup -HostName myclient.mydomain.com -log logs/lookup.log

Tip: During the connectivity check, you can stop the data transmission by pressing the Esc key.

Result

The command returns the network interface Information of the target client.
