Join Greg Sowell for an in-depth discussion in this video FTP and TFTP, part of Foundations of Networking: Protocols and CLI Tools.
- File Transfer Protocol or FTP…has been used to transfer files since 1971.…FTP depends on TCP for reliable delivery.…FTP is great for plain text transmissions,…but can also use TLS or SSL to encrypt the sessions.…FTP can run in either active or passive modes.…In both modes, the session is initiated on TCP port 21.…In active mode, the client will inform the server…on what port the server should access the client at.…
The server will then initiate a connection to the client…from TCP port 20 for the data transfer.…In most situations, a client's machine…will be behind a firewall or utilize a software firewall…which will prevent incoming connections.…If this is the case, passive mode should be used.…In passive mode, the server provides a specific port…for the client to connect to.…The client then initiates the outbound connection…to the data server for a data transfer.…Trivial File Transfer Protocol or TFTP…is a light transfer protocol.…
Its nature is perfect for devices…that pull their configuration on boot…or as a service for network hardware to transfer…
