ABSTRACT
Networks grow larger and larger by
the order of the organization’s growth, maintaining the networks will be a huge
task. In any networking environment
there will be many factors that are to be considered by the administrator
(server).The administrator will not be having firm grip on the end users.
Moreover the administrator has to know all the details of the end-users from
network it and he may not be able to configure the systems of the end-users
from his place.
Gover LAN is an enterprise project that is used to
maintain and govern an enterprise LAN in a simpler and secured way. It aims in
assisting the network administrators by maintaining proxy servers and port
mappings. Gover LAN plays a vital role for Enterprise Administration, System
Administration and User-Level Support Team.
Gover LAN is mainly classified into 3 major
components:
1.
Gover LAN Management Console
2.
Gover LAN Scope Actions
3.
Gover LAN Remote Control
The Gover LAN Management Console performs real-time
remote administration and trouble-shooting on end-users.
Gover LAN Scope Actions enables us to take control
of the machines, users and groups as a whole.
What
is GoverLan?
GoverLan is
an enterprise project that is used to
maintain and govern an enterprise
LAN in a simpler and secured way. It aims in assisting the network
administrators
by maintaining proxy servers and port mappings.
Gover LAN plays a vital role for Enterprise Administration, System
Administration and User-Level Support Team.
What is a Lan?
Local area networks, generally called LANs are privately-owned networks
within a single building or campus of up to a few kilometers in size. They are
widely Used to connect personal computers and workstations in company offices
and factories to share resources and exchange information LANs are
distinguished From other kinds of networks by 3 characteristics.
(1) Their size
(2) Their transmission Technology
(3) Their topology.
LANs are restricted in size, which means that
transmission time is bounded in advance. It also simplifies network
management.LANs often use a transmission technology consisting of a single
cable to which all the machines are attached, like the telephone company party
lines once in rural areas. Various Topologies are possible for broadcast LANs.
In a bus (i.e., a linear cable), at any Instant one machine is the master and
is allowed to transmit. All others are required to refrain from sending. A second
type of broadcast system is the ring. In a ring. Each bit propagates around on
its own, not waiting for the rest of the packet to which it belongs.
Broadcast networks can be further divided into static and dynamic,
depending in how the channel is allocated. A typical static allocation would be
to divide up time into discrete intervals and run a round robin algorithm,
allowing each machine to broadcast only when its time slot comes up.
Dynamic allocation methods for a common channel are
either centralized Or decentralized. In centralized there is single entity, but
in decentralized there is no central entity; each machine must decide for
itself whether or not to transmit.
The other kind of LAN is built using point-to-point
lines.
What is HTTP Proxy Server?
The Http Proxy Server is a
piece of software of that dials up to the Internet. When a node has been
connected with Internet, the access of Internet could be done. Through only
from that single node, if number of clients has to access the Internet to the
net, this Proxy Server concept has greater utility of sharing the Internet to
the clients by changing that connected node as a server so that the users in
the network can access Internet throughthat proxy. This server
uses the concept of multithreading; each thread being expected a request from
the client. A server speaks about the
client side of a protocol to another server. This is often required when
clients have certain restrictions on which server they connect to. Thus, a
client would connect to a Proxy Server, who did not have such restriction; the
Proxy would in turn communicate to the client.
When a popular website is being hit by hundred’s of
users, a Proxy Server can get the
contents of the web server’s popular page once, saving expense internet work
transfers, while providing faster access to those page to the clients.
What
is Scanning?
The process of gathering
information on computing systems, which may be used for system maintenance,
security assessment and investigation, and for attack.
What
is Port Mapping?
The process of finding the active ports that
is , sending data packets to selected service port numbers (HTTP-80, Telnet-23,
etc.) of a computing system with the purpose of identifying available network
services on that system.
What is Port Scanning?
Essentially, a port scan
consists of sending a message to each port, one at a time. The kind of response
received indicates whether the port is opened or not.
The simplest port scan
tries (i.e., sends a carefully constructed packet with a chosen destination
port number) each of the ports from 0 to 65535 on the victim to see which ones
are open.
Motivation
for Http Proxy Server:
Being in the INTERNET WORLD, People want to
send message electronically at a faster speed that to without any data loss.
It’s difficult to connect each node with a modem and
other equips for Internet access and when more number of clients accesses the same
WebPages, these could slow done the process and there is a chance of network
failure.
This motivated us to develop software that will provide a
faster access without any data loss and network failure.
Motivation for Port Mapping
The server must be able to control all of its
clients from the highest level itself. Hence, it has to know all the services
accessed by clients. In general Port
Scanning utilities are used for checking which ever ports are active on the
network so that if some restricted port is opened, the administrator will be
notified of this and if needed he can close the Port as well as the application
that is used on the port.
