Which of the following statements about the concept of ports in the TCP/IP protocol stack is TRUE? O Ports are used for multiplexing/demultiplexing network flows at the application layer. TCP and UDP support port numbers, while IP does not. O Ports are used for multiplexing/demultiplexing flows at the transport layer. TCP supports port numbers, while UDP and IP do not support ports. Ports are used for multiplexing/demultiplexing network flows at the transport layer. TCP and UDP support port numbers, while IP does not. Ports are used to identify the IP interfaces in the network. TCP and UDP do not support port numbers, while IP does. O Ports are used for multiplexing/demultiplexing network flows at the network layer. TCP and UDP support port numbers, while IP does not.
A client PC has two simultaneous connections to the same webserver application program on a webserver. What will be different between the TCP segments that the client sends on the two connections? Would you make any recommendations to change the situation? Why or why not?
Write a Python program that assists you in managing a network of devices for your company. You need to keep track of the IP addresses, MAC addresses, and device types in your network. List: Create a list named device_ip containing IP addresses as strings. Your network consists of one router and at least one of each of the following devices: switch, server, workstation, printer, and mobile device. Each device should have a unique IP address. The router's IP address should be '192.168.1.1'. Print each IP address on a new line. Tuple: Since MAC addresses of devices are unique and not changing, you decide to store them in a tuple named device_mac. Create this tuple with MAC addresses corresponding to each IP address. A MAC address looks like '00:14:22:01:23:45'. Print each MAC address on a new line. Set: You also want to keep track of the different types of devices in your network. As the device types are distinct and do not have duplicates, create a set named device_type that contains…
Is this statement true or false? Assume that the most recent SampleRTT on a TCP connection is 1 second. The connection's current TimeoutInterval value must be greater than one second.
A TCP endpoint can abort the connection, which entails the sending of a RST Packet rather than a FIN. The endpoint then moves directly to TIMEWAIT. To abort a connection using the Berkeley socket library, one first sets the SOLLINGER socket option, with a linger time of 0. At this point an application close() triggers an abort as above, rather than the sending of a FIN.
The following captured network traffic shows the three-way handshake to establish a TCP connection. Please write a TepDump command running at the client side to capture all the packets with flag "S" only between the host "tclient.net" and the telnet server "telenet.com". When check TCP flags, please use the format 'tep[tcpflags]&tcp-syn', "tep[tepflags]&tcp-push', 'tcp[tcpflags]&tcp-ack', and so on.

I made a TCP server using socket python,basically my server can: - Upload (“put”) request: The client should, at the very least, open (in binary mode) the local file defined on the command line, read its data, send it to the server through the socket, and finally close the connection. - Download (“get”) request: The client should, at the very least, create the local file defined on the command line (in exclusive binary mode), read the data sent by the server, store it in the file, and finally close the connection. To avoid accidents, the client should deny overwriting existing files. - Listing (“list”) request: the client should, at the very least, send an appropriate request message, receive the listing from the server, print it on the screen one file per line, and finally close the connection. I want you to draw an ER diagram that can show the process above please.
Can you please implement me code for c programming language using for windows not linux That using multithreaded tcp connection doing just parity check and checksum error detection My first client name be client 1 and message hello server Same for client 2 so lastly can pass error detections and my message not be discarded
You are supposed write two separate TCP socket programs that implements both Client/Server parts of a communication such that Client will send two integers and Server will reply with the sum of those integers. In your programs you should clearly indicate the header files that are used Using a suitable diagram, Briefly explain how the two programs communicate with each other?
Step2: open Wireshark in the Windows machine and set a filter "tcp". Use hping3 command in Kali Linux to send two packets to the windows machine like the following: - packet nature : tcp - number of packets : 2 - destination port: 110 - Flag SYN active - interval time 100 microseconds write the command here and give a screenshot from Kali and Wireshark capture of those two packets from wireshark can you tell what correspond to tcp destination port 100 ? Step 3: set Wireshark filter now to "udp" to see only udp packets Send two packets to the windows machine like the following: - packet nature : udp - number of packets : 4 - destination port : 67 - interval time 100 microseconds write the command here and give a screenshot from Kali and Wireshark capture of those packets from wireshark can you tell what correspond to udp destination port = 67 ? and what its hexadecimal representation
