Hello, I need help creating a TCP SYN packet in Scapy. It can have any IP source and destination address, and any TCP source and destination address (for the example, just use the address 127.0.0.1 for source/destination). I need this packet to be sent and received using the sr() function of Scapy. Thank you kindly!

An Internet user would like to transfer a message from his computer (host A) to another computer (host B). The size of the message passed to the IP layer is 3800 bytes. The datagram(s) carrying the message will have to cross two routers (R1 and R2) and 3 networks (NET1, NET2, and NET3) as described in the above figure. Each of these networks has a specific MTU (for example the MTU of network 1 is 1500 bytes. MTU here stands for Maximum Transmission Unit, the largest data that a frame can carry). Fill the table with the IP datagram(s) needed right after passing through NET3 (no need to show your fragmentation for N1 or N2). Assume a 2-byte options in the header. Show all your details (for partial points in case your numbers are incorrect). NET1 MTU=1500 R1 NET2 MTU=640 R2 NET3 MTU 1500 V BIU Fragment # Format Offset Flag (3 bits) Data Length Total Length ...

Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes

List the three auxiliary protocols at the network layer of the TCP/IP suite that are designed to help the IPv4 protocol. When an IP datagram is travelling between networks, can the value of the TTL field in the IP datagram be any of the following? Explain your answer. 23 0 1 301 Which field(s) in the datagram are responsible for gluing together all fragments belonging to the original datagram?
