NON-INTRUSIVE REMOTE MONITORING OF SERVICES IN A DATA CENTREcscpconf
Non-intrusive remote monitoring of data centre services should be such that it does not require
(or minimal) modification of legacy code and standard practices. Also, allowing third party
agent to sit on every server in a data centre is a risk from security perspective. Hence, use of
standard such as SNMPv3 is advocated in this kind of environment. There are many tools (open
source or commercial) available which uses SNMP; but we observe that most of the tools do not
have an essential feature for auto-discovery of network. In this paper we present an algorithm
for remote monitoring of services in a data centre. The algorithm has two stages: 1) auto
discovery of network topology and 2) data collection from remote machine. Further, we
compare SNMP with WBEM and identify some other options for remote monitoring of services
and their advantages and disadvantages.
Design of management Application allow to control the functionality of each device.
if some devices experience havoc, then we have to keep log of the wrecks of incidents.
With the use of SNMP-MIB we can keep log of the events occurred in the system, which would help in identifying the exact cause of the problems, and would help the administrator in recovery of system.
Example: consider an air conditioner , which can be controlled by service discovery like UPnP, but to monitor its performance, whether its cooling performance is appropriate or not, A management protocol like SNMP could be beneficial.
SNMP allows the standardization of the system and homogeneous interface to the administrator for the management of SNMP and UPnP based devices.
UPnP (Universal Plug and Play Protocol) enables discovery and control of networked devices and services, such consumer electronic equipments. UPnP encompasses two main objects, control point and a device, and use XML,SOAP as the communication protocol

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.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

PDUs
SNMPv3 defines eight types of packets (or PDUs):
GetRequest, GetNextRequest, GetBulkRequest, SetRequest, Response, Trap,
InformRequest and Report.
GetRequest: it is sent from the manager (client) to the agent (server) to retrieve
the value of a variable or a set of variables.
GetNextRequest: it is sent from the manager (client) to the agent (server) to
retrieve the value of a variable. It is mostly used to retrieve the values of the
entries in a table.
GetBulkRequest: it is sent from the manager (client) to the agent (server) to
retrieve a large amount of data. It can be used instead of above two PDUs

10. PDUs
SetRequest: it is sent from the manager (client) to the agent (server) to set (store)
a value in a variable.
Response: it is sent from an agent (server) to the manager (client) in response to
GetRequest or GetNextRequest. It contains the values of the variables
requested by manager.
Trap: the trap PDU is sent from the agent (server) to the manager (client) to
report an event, for example: if the agent is rebooted, it informs the manager
and reports the time of rebooting.
InformRequest: it is sent from one manager (client) to another remote manager
to get the value of some variables from agents under the control of the
remote manager. The remote manager responds with a Response PDU.
Report: the Report PDU is designed to report some types of errors between
managers. It is not yet in use.
