Dissecting FTP

The video tutorial provides an in-depth look at FTP, explaining its architecture, modes, and security features. It covers the differences between active and passive modes, highlighting the challenges and solutions related to firewalls. The tutorial also discusses FTP reply codes and demonstrates how to use Wireshark to analyze FTP traffic, emphasizing the importance of understanding clear text transmissions and the potential for adding security layers.

What is a key difference between FTP and HTTP?

• FTP runs in encrypted mode by default.

• HTTP uses two main channels for communication.

• FTP maintains session state information.

• HTTP can maintain the current directory.

In active mode, what is a major drawback when the client is behind a firewall?

• The client cannot initiate a command.

• The server cannot reach the client.

• The server uses only one port.

• The data transfer is always encrypted.

How does passive mode resolve the firewall issue in FTP?

• By using a single port for all communications.

• By encrypting all data transfers.

• By allowing the server to control all connections.

• By allowing the client to control all connections.

What does an FTP reply code starting with '2' indicate?

• The request action has been completed successfully.

• The requested action is being initiated.

• The command was not accepted, try again.

• The command has been accepted but is pending further information.

What tool is used to analyze FTP communication in the demonstration?

• SSH

• Wireshark

• FileZilla

• Telnet

What is the purpose of multiplying the number 217 by 256 in the passive mode demonstration?

• To calculate the IP address.

• To encrypt the data transfer.

• To determine the port number for data communication.

• To establish a control channel.

What color represents server communication in the Wireshark analysis?

• Red

• Green

• Blue

• Yellow
