0 O O 0 . . . Before, we have looked at the hex value to decode what the numbers mean. For this assignment, we will be doing the opposite - given information about the packet, the goal will be to build the corresponding hex packet. Your task: Build a hex packet, as if it was just extracted from the network, given the following information and diagram. If (hex) is not stated, the number is decimal. It is a TCP packet Address information: HW Dest (hex) = 00:50:56:86:8F:33 - HW Src (hex) = 00:00:0C:31:01:AB IP Dest = 64.39.3.146 IP Src = 199.100.16.100 o Port Dest = 53258 Port Src = 3128 IP Type of Service: 0 TTL: 60 Flags - IP: Don't Fragment is set • TCP: Acknowledgement is set IDs IP (hex): 39CF TCP Sequence (hex): 1770 EDC8 - TCP Acknowledgement (hex): 7D46 9EDB Options No IP options TCP options (hex): 0101 080A 8EBE A04A 1CE0 5196 • Checksums . IP (hex): E973 - TCP (hex): BC1E • TCP window size: 1024 • TCP urgent pointer: 0 You can figure out all other missing fields using the information above. Using scratch paper may be beneficial for this assignment - write out each header field, fill in the numbers with the appropriate information, and then build your packet. For instance, creating and filling in a table may help (not all fields are listed in the example below): 0 O O O Ethemat der Det SA Hester Version Header Lampe of Senice TOP Header See on Dest Port Type/Lan SIPA Dest Poption Line Option Oy 319 360
