  • Configuring FTP Virtual Servers
    • The File Transfer Protocol (FTP) is used for file transfers between computers running TCP/IP
    • FTP service is included with IIS 6.0
    • FTP uses two ports (TCP ports 20 and 21)
      • Port 21 carries connection initiation and diagnosis information
      • Port 20 carries data
    • FTP uses Transmission Control Protocol (TCP)
      • Connection-based protocol, session precedes data transfer
  • File Transfer Protocol
    • Features of TCP include:
      • Sending computer waits for an acknowledgement and retransmits data if it is not received
      • Packets are assigned a sequence number
      • Packets contain a checksum for ensuring integrity
    • FTP requires a server running FTP server software and clients must run FTP client software
    • There are many free and shareware utilities that can be downloaded for running FTP
  • Configuring FTP Properties
    • Multiple FTP sites can be configured on a single IIS 6.0 server
    • Each site operates independently and runs transparently
