Task 2. Analyse Ping Packet Capture Previously you captured ping packets between your
Windows host and OpenWRT Linux guest. In this task you will analyse the operation of ping
from a protocol perspective. To do so, open the ping packet capture file (.pcap file) with
Wireshark. To analyse the packet capture and learn about how ping, protocols and layering
works, do the following: a) Inspect the packets in Wireshark (many are very similar, so focus on
the different packets). b) Draw a network diagram, labelling the devices with IP addresses and
MAC addresses where known. c) Explain the purpose of ARP packets. Who sent them? Why?
Who did they send to? d) Draw a packet diagram for the 1st ARP packet that shows
encapsulation. Label the size (in Bytes) of the entire packet as well as of the different headers,
data, footers (where they exist). e) Explain the first two ICMP packets. f) Draw a packet diagram
for the first ICMP packet..

This presentation features a walk through the Linux kernel networking stack covering the essentials and recent developments a developer needs to know. Our starting point is the network card driver as it feeds a packet into the stack. We will follow the packet as it traverses through various subsystems such as packet filtering, routing, protocol stacks, and the socket layer. We will pause here and there to look into concepts such as segmentation offloading, TCP small queues, and low latency polling. We will cover APIs exposed by the kernel that go beyond use of write()/read() on sockets and will look into how they are implemented on the kernel side.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
