Verifying Network Connectivity in Server Mode Using the Network Test Tool in the Command Line

You can run the tool in client mode to check the quality of the network connectivity between two client computers and to measure the bandwidth utilization for data transfer.

When the tool runs in server mode, the client where you run the tool acts as the listening server and waits for incoming connections from the designated target client. When the target client establishes a connection with the listening server, the tool displays the connectivity check as successful.

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 -server -BindIP  IP_address -log location -SrvPort number

Where:

• -server runs the tool in server mode. This means that the client where you run the tool is designated as the listening server.

• -BindIP specifies the local IP address that the tool will use to listen for incoming connections.

• (Optional) -SrvPort specifies the port number on the client acting as the listening server. This port is used to communicate control information with the target client. If not specified, port number 25000 is used.

• (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 -server -BindIP 172.16.0.52 -SrvPort 25001 -log C:\server.log

• On UNIX, Linux, or Macintosh:

  ./CvNetworkTestTool -server -BindIP 172.16.0.52 -SrvPort 25001 -log logs/server.log

Result

The command indicates whether the data was successfully transferred between the listening server and target client, or vice-versa.
