Remote Administration and Network Monitor

REMOTE ADMIN AND NETWORK MONITORING

Abstract:

Remote monitoring is real time monitoring tool for windows network and analysis

through log file and construct a real time graph by throughput in the network.

In our project, we are going to perform operations like

1. We monitor the packets in the network in real time.

2. We will know whether the packet is TCP, UDP or IP etc.

3. We will be able to monitor the packet transformation information i.e., from which

host to which host.

4. Remote Administration.

Remote Admin is used to admin the remote system from the server system. With

the help of this application we able to turnoff, restart, logoff and file transfer and remote

software installation or running remote application. Administrators and users with

administrator rights can only use this tool for accessing remote system and perform

different operations.

MODULES :

MONITOR THE REAL TIME NETWORK TRAFFIC.

MAINTAINED LOG FILE IN THE SERVER.

CONSTRUCT A GRAPH USING A THROUGHPUT.

ADMIN THE REMOTE SYSTEM LIKE REMOTE CONTROLS.

MONITOR THE REAL TIME NETWORK TRAFFIC

Monitors the traffic in GUI Window. Select a network adapter to monitor .It will

show date, time, traffic occurrence, sender and receiver and we will be able to see the

data transmitted in bytes. We monitor the packets in the network in real time.

1

By verifying the packets in the client system. Our system enables the user to

know whether the packet transmission over TCP, UDP or IP. And also it is possible to

know the source and destination system. From which host to which host. For the secured

transmission we will get the acknowledgement from the client about the packet receiving.

MAINTAINED THE LOG FILE IN SERVER

The server is in the responsible position to maintain the log file which contains

the details about the file transmission date, time and number of packets. We will view

the network monitor details in future. When ever the server response to client all the

details will be maintained in the log system. This log file is used for future reference.

In this module we store all details monitored in the system to display in future

CONSTRUCT A GRAPH USING A THROUGHPUT.

In this module we construct a graph in GUI window .We construct the graph by

throughput of the network traffic. The pictorial representation of the network work

monitoring. The servers construct the graph using a throughput of the network analysis.

In this module we construct a graph in GUI window. This is constructed by using the

throughput point.

ADMIN THE REMOTE SYSTEM LIKE REMOTE CONTROLS.

Remote Admin tool helps organizations achieve operational excellence through

delivering satisfactory service quality, reliability, and lower total cost of ownership for

multiple platform environments. Remote Admin Tool helps the business running, while

lowering the complexity and cost of managing the server infrastructure. Following are the

function which is involved in the remote administration.

2

EXECUTING COMMANDS

Remote Admin should allow user to,

Execute single commands,

Custom batch for multiple commands processing

Save the modified or customized settings.

Can restart or shut down the remote system.

Clear the screan and clear the debug console.

ALLOW FILE TRANSFER

This Tool allows user to perform operations like single file transfer,

multiple file transfer between local and remote system. This should be achieved

by using,

Instant File Transfer

This tool allows user to perform Instant Upload, Instant Download,

where single file is uploaded/downloaded instantly.

Delay File Transfer

This tool allows user to perform delay Upload, delay Download, where

multiple files are stored in queue and later it is uploaded/downloaded to a

particular location.

FILE BROWSER

The Tool allows the user to browse through the files and directories of the remote

system. It also allow user to perform file operations like Copy, move, Delete, Create,

Rename, Edit, and View Property of files.

MONITORING CONNECTION

Remote Admin Tool allow user to monitor the connection status of remote

computer, and to identify which server is currently down or not available (either due to a

physical problem e.g.

3

Network link down, or a logical error e.g. the failure of RMI Service).It should

also provide functions like refresh connections, restart logical connections and shut down

connections.

FEATURES OF PROPOSED SYSTEM

It is highly portable to a great variety of computer platforms

Invoke single/batch operating system command(s) of remote systems

locally,

Perform file operation on remote systems locally,

Transfer of files between remote and local computers,

Editing file contents on remote systems locally,

Monitoring the connection status of managed systems,

File transfer protocol is used to connect two computers over the Internet so that

the user of one computer can transfer packets and perform file commands on the other

computer. Specifically, FTP is a commonly used protocol for exchanging files over any

network that supports the TCP/IP protocol (such as the Internet or an intranet). There are

two computers involved in an FTP transfer: a server and a client. The FTP server,

running FTP server software, listens on the network for connection requests from other

computers. The client computer, running FTP client software, initiates a connection to the

server. Once connected, the client can do a number of file manipulation operations such

as uploading files to the server, download files from the server, rename or delete files on

the server and so on. Any software company or individual programmer is able to create

FTP server or client software because the protocol is an open standard. Virtually every

computer platform supports the FTP protocol. This allows any computer connected to a

TCP/IP based network to manipulate files on another computer on that network

regardless of which operating systems are involved (if the computers permit FTP access).

There are many existing FTP client and server programs.

4

In active mode, the FTP client opens a random port (> 1023), sends the FTP

server the random port number on which it is listening over the control stream and waits

for a connection from the FTP server. When the FTP server initiates the data connection

to the FTP client it binds the source port to port 20 on the FTP server.In passive mode,

the FTP Server opens a random port (> 1023), sends the FTP client the port on which it is

listening over the control stream and waits for a connection from the FTP client. In this

case the FTP client binds the source port of the connection to a random port greater than

1023.

TECHNOLOGY USED

Java

INTRODUCTION

Java is an object-oriented programming language developed initially by James

Gosling and colleagues at Sun Microsystems. The language, initially called Oak (named

after the oak trees outside Gosling's office), was intended to replace C++, although the

feature set better resembles that of Objective C.

Java, a platform independent programming language helps in building any kind

of application of our interest; Java uses a compiler to convert the source code into

architectural independent byte code. These are executed over a Java Virtual Machine

(JVM), which is an idealized java processor chip usually implemented in software rather

than hardware .Java was developed to include methods for Internet data manipulation.

Java applications can be written once and run on any machine having a Java Virtual

Machine as part of its operating system.

SWING

Swing is a GUI toolkit for Java. It is one part of the Java Foundation Classes

(JFC).Swing includes graphical user interface (GUI) widgets such as text boxes, buttons,

split-panes,and tables. Swing widgets provide more sophisticated GUI components than

the earlier Abstract Window Toolkit.Since they are written in pure Java, they run the

same on all platforms,that is uniform behaviour in all platform, unlike the AWT which Is

tied to the underlying platform's windowing system.

Swing supports pluggable look and feel – not by using the native platform's

facilities,but by roughly emulating them. This means you can get any supported look and

feel on any platform. Swing is a platform independent, Model-View-Controller GUI

framework for Java. It follows a single-threaded programming model.

REMOTE METHOD INVOCATION (RMI)

. Remote method invocation allows applications to call object methods located

remotely, sharing resources and processing load across systems. Unlike other systems for

remote execution which require that only simple data types or defined structures be

passed to and from methods, RMI allows any Java object type to be used - even if the

client or server has never encountered it before. RMI allows both client and server to

dynamically load new object types as required. In this article, you'll learn more about

RMI.

Remote Method Invocation (RMI) facilitates object function calls between

Java Virtual Machines (JVMs). JVMs can be located on separate computers - yet one

JVM can invoke methods belonging to an object stored in another JVM. Methods can

even pass objects that a foreign virtual machine has never encountered before, allowing

dynamic loading of new classes as required. This is a powerful feature

Overview of the project

Command Line

Run Command

This enables the local user to open the required application in the remote

machine.

Custom Batch

This feature allows to create a batch which consists of few applications on the

whole. We can create a maximum of 5 applications in a single batch. The

execution of this batch opens all the applications that are created,

simultaneously in the remote machine.

Clear Screen

This feature helps the user to clear the current remote admin screen.

Clear Debug

This feature helps the user to clear the Debug console area.

Login features

The remote system can be restarted, shut down from the local system itself.

File Browsers

This module provide platform to browse Files and directories of the remote system

and perform different file operations. Those files available in the remote machine can be

viewed from the local system itself. Those files and directories can be updated, deleted,

edited,renamed, etc,. also the local user can create new directories and also files for the

directories in the remote machine.

File Transfers

This module allows users to instant/delay Upload and download files in ASCII and

Binary format. The files and the directories in the romote machine can be moved from

the local machine to the remote system (ie, uploading) or moved from the remote system

to the local machine (ie downloading).

This transfer of files from either side can be done between different directories also. The

transfer of files and directories can be done to move them within the same system but

between the directories also.

9

Connection Monitor

This module allows users to monitor the connection status of the remote systems.

Restart/Refresh RMI connection between the systems is also done in this module.

12. Conclusion

The project entitled “Remote Admin Tool” is developed and tested successfully.

It meets the specified requirements. The REMOTE ADMIN TOOL accessing the remote

system over the network regardless of the target computers platform has been verified

effectively. This feature of being independent of the remote system platform plays a good

role in area where different OS is being used.

The Command line feature of this software is found to effectively open the

required application in the remote machine , also the other functions in this module such

as the custom batch which creates a batch of applications, the clear screen which clears

the remote admin screen, the clear debug function which clears the debug console area,

the save configuration that saves the batch configuration are tested to work quite

effective. The File Transfer module is found to upload and download the files and

directories on either side in a very small span of time. The file browser available in the

REMOTE ADMIN TOOL makes it easy for the user to browse the files of the remote

system and carry out various operations such as cut, copy, paste, rename, edit, details,

delete etc,.The Connection monitor also tested effective. Various tasks and operations to

be executed at remote computer are now automated by instructions defined in Remote

Admin tool. It provides a user-friendly interface on the client side for easy accessing of

remote systems.

Thus, Remote Admin tool is highly portable to a great variety of computer

platforms that support JAVA

13. Limitation

Managed Server List export & import is limited in the remote admin tool.

Server key has to be transferred to the target system by any other technology for

authentication purpose.

13.1 Future Enhancement

43

This tool can provide Application Programming Interface for programming plug-in and

for integration with external system like mobile devices and embedded systems.
