ensured, i.e., use the “Ping” command  to verify the  connectivity between  the  FTP client  and 
server before running the FTP program. If ping fails, you will need to check for appropriate 
troubleshooting information to recover the link connectivity. 
  The  following  is  what  the  message  displays  when  files  are  successfully  transferred. 
Otherwise, please verify link connectivity and retry “copy” command again.
