This book is intended for beginning through intermediate users and covers all the
protocols involved in TCP/IP. Each protocol is examined in a fair level of detail to show
how it works and how it interacts with the other protocols in the TCP/IP family. Along
the way, this book shows you the basic tools required to install, configure, and maintain
a TCP/IP network. It also shows you most of the user utilities that are available.
This lab will help to develop a better understanding of the seven layers of the OSI model. Specifically
as they relate to the most popular functioning networking model in existence, the TCP/IP model. The
Internet is based on TCP/IP. TCP/IP has become the standard language of networking. However,
the seven layers of the OSI model are the ones most commonly used to describe and compare
networking software and hardware from various vendors. It is very important to know both models
and be able to relate or map the layers of one to the other.
f you are like the rest of the networking community, you probably have
many certifications. Certification is one of the best things you can do for
your career in the computer or networking field. It proves that you know
what you’re talking about when it comes to the area in which you are
In this book, you’ll find out what the Network+ exam is all about. Each
chapter covers a part of the exam. At the end of each chapter, there are
review questions to help you prepare for the exam....
A networking firewall is a logical barrier designed to prevent unauthorized
or unwanted communications between sections of a computer network.
Linux-based firewalls besides being highly customizable and versatile are also
robust, inexpensive, and reliable.
The two things needed to build firewalls and QoS with Linux are two packages
named netfilter and iproute. While netfilter is a packet-filtering framework included
in the Linux kernels 2.4 and 2.6, iproute is a package containing a few utilities that
allow Linux users to do advanced routing and traffic shaping....
Explain the operations of IGMPv2 and how IGMPv2 utilizes Join Group and Leave Group messages. Explain the operations of IGMPv3 and how IGMPv2 and IGMPv3 interoperate. Describe the methods used to deal with multicast in a Layer 2 switching environment.
This lab exercise helps develop an understanding of IP addresses and how TCP/IP networks operate. It is primarily a written lab exercise. However, it would be worthwhile to review some real network IP addresses using the command line utilities ipconfig for Windows NT/2000/XP or winipcfg for Windows 9x/ME. IP addresses are used to uniquely identify individual TCP/IP networks and hosts, such as computers and printers, on those networks in order for devices to communicate. Workstations and servers on a TCP/IP network are called hosts and each has a unique IP address.
In-Depth TCP/IP Networking
Understand methods of network design unique to TCP/IP networks, including subnetting, CIDR, NAT and ICS
Explain the differences between public and private networks
Describe protocols used between mail clients and mail servers, including SMTP, POP3, and IMAP4
Employ multiple TCP/IP utilities for network discovery and troubleshooting
Hướng dẫn này là giới thiệu về Ethereal và làm thế nào nó có thể được sử dụng như một trợ lý vô giá trong việc thực hiện phát hiện xâm phạm. Tôi giả định người đọc có một sự hiểu biết cơ bản của khái niệm an ninh mạng, TCP / IP, và đã nhìn thấy lưu lượng mạng. Một khi bạn đã quen thuộc hơn với Ethereal công trình, tôi sẽ bao gồm một số ví dụ thực tế của việc sử dụng nó để phát hiện và phân tích lưu lượng nguy hiểm....
In the recent years the electrical power utilities are undergoing rapid restructuring process
worldwide. Indeed, with deregulation, advancement in technologies and concern about
the environmental impacts, competition is particularly fostered in the generation side
thus allowing increased interconnection of generating units to the utility networks. These
generating sources are called as distributed generators (DG) and defined as the plant which is
directly connected to distribution network and is not centrally planned and dispatched.
This lab focuses on the Telnet (remote terminal) utility to access routers remotely. Telnet is used to connect from a local router to another remote router in order to simulate being at the console on the remote router. The local router acts as a Telnet client and the remote router acts as a Telnet server. Telnet is a good testing or troubleshooting tool since it is an application layer utility. A successful Telnet demonstrates that the entire TCP/IP protocol stack on both the client and server are functioning properly. Telnet from the workstation as a client into any router with...
A loopback test is a connection from the database server back to itself. Many
network protocols provide a means of testing network connections. The utility
PING can be used for TCP/IP network.
In a TCP/IP network, each computer has a unique IP address. A name resolution
service, such as Domain Name System (DNS), can be used to map the IP address
of a computer with its host name. If a name resolution service is not used, then the
mapping is typically stored in a centrally maintained file called hosts. This file is
located in the /etc directory on UNIX and the...
The BACnet protocol currently uses the connectionless User Datagram Protocol (UDP)
for both Annex H and BACnet/IP communications. However, it is possible that Trans-
mission Control Protocol (TCP) transport will be utilized for some service in the future,
and so threats specific to TCP have been included. Even if TCP/IP is never used as part
of the BACnet protocol, it still can be used to gain access to the building control system
web servers, get access through the corporate firewall, and be used for denial of service
attacks on the external network on which the BCS may depend.
