6. You can start to run the VM and work on the lab. Hope you enjoy it.

THIS IS THE LAB THAT I NEED TO DO

THANKS

1. Please check lab setup document to download and install a SEED VM. A SEED VM has pre-installed Wireshark. The password for the root user is dees

Task 1:

In this lab, you will use Wireshark to capture packets of different applications, including Telnet and sftp, to understand TCP/IP protocols and related packet format.

1) Telnet

In the terminal, please type

telnet 127.0.0.1

Then, type the user id: seed, and password: dees to login to the telnet server. When you want to finish the telnet service, please type exit.

Use Wireshark to capture the packets for the activities of TCP connection, login (user ID, password), and connection close. To easily locate the requested packets, you should set the filter. For example if you set the filter as: port 23, it will only display the packets to and from port 23.

Submission: screen image of the captured packets.

Please explain:

a) what packets are used for TCP connection (three way handshake), how the three-way handshake works?

b) what packets are used for login? Can you see the user ID and password?

c) what packets are used for closing the connection?

2 ) Sftp

In the terminal, please type

sftp 127.0.0.1

Then, type the password: dees to login to the sftp server. When you want to disconnect, please type bye.

You can set the display filter, for example port 22, which will only display the packets to and from port 22 (sftp server port). For another example, you can set filter as ssh, which only displays the packets related to ssh protocol.

Submission: screen image of the captured packets, and also please answer:

a) Does sftp have the three-way handshake for the TCP connection? Are they the same as those of Telnet?

b) How can sftp provide secure connection?

c) Can you still view the typed command after you logged into the sftp server? Why?

Task 2: Routing table

In the terminal, please type

Route n

a) Please explain the route table.

b) Please add a subnet 193.167.1.0 with the default gateway 10.0.2.1

c) Please remove the added record from the routing table.

Submission: screen image of the commands
