Use of PORT command

• The FTP PORT command tells the server what IP address and port with which to initiate a data session

• Format:

• • 6 bytes spelled out in ASCII
  • First 4 are the IP address
  • Next 2 are the high order (H) and low order (L) bytes of the port number

• Port number = 256*H+L

• • E.g., 256*6+245 = 1781
