This Project “Cross – X†is a cross platform explorer tool that allows universal access of; all types of file system in a heterogeneous network environment having different platforms such as Windows, Linux, Solaris, etc. The tool allows all normal operations such as open, delete, copy, cut, paste, rename, property changing etc to be performed on the files of all types. The tool implements security in file access by authenticating the user before entering into each system with the username and password of the particular system being accessed. All the existing systems for file sharing between different platforms are mainly focused in sharing the file system between any two particular platforms, For Example, SAMBA SERVICE is used to share files between the Windows and the Linux Platform. This draw back of restricting the file sharing between only two platforms is being solved in this project by allowing neutral access of all the file systems by all other platforms. When an user works in a particular Operating System he/she can access/view the file systems native to that Operating System. If he/she wants to access/view the file system of other platforms (like Linux, Solaris, MAC, etc) in a heterogeneous network, the application in the parallel Operating System acts as the server, which sends response to the request from the requesting Client and sends the corresponding file information to the Cross – X application. The System consists of a Centralized Server which maintains and manages all the client information in it and is used to create and authenticate users of the system. The Clients once they are activated register themselves with the Server and the list of active clients is informed to the other clients by the server. The Server and the Client systems are implemented using RMI (Remote method Invocation) Registry by which they establish connections and transmit information between them. The File information are transferred form one client to the other on request and is transferred in the form of XML (Extensible Markup Language) data which is then parsed at the destination to get the original data sent. The mapping of files to their appropriate application is done. The tool “Cross-X†uses Session Semantics for the purpose of file sharing which reflects the change made in a shared file to other processes accessing that file only at the end of the particular Session and the Data caching model used for the transfer or access of remote files is the File-level transfer model which transfers the entire file on request. The project has been implemented using Java. Since java is a platform independent language (i.e.), any machine which has JVM( Java Virtual Machine) of that particular platform can be used to run the java class files, So we will be able to implement the project in any platform and will be able to access all different file systems. The Prerequisites of this tool is to have the Java Runtime Environment corresponding to the platform in which the tool is implemented. The Complete information about the project is provided in the Web page http://cross-x.tripod.com This Project “Intranet Mail and Chat Server†implements the facility of distributing electronic mails such as plain text mails and mails with attachments within the clients of an Intranet and also implements the facility of conventional chat through text and Voice chat. The mail server is implemented by designing the Application Layer protocols
Mail Transfer Agent (MTA) is the program responsible for delivering e-mail messages. Upon receiving a message from a Mail User Agent or another MTA it stores it temporarily locally and analyses the recipients and either delivers it (local addressee) or forwards it to another MTA (routing). In either case it may edit and/or add to the message headers. Mail User Agent (MUA), The program that allows the user to compose and read electronic mail messages. The MUA provides the interface between the user and the Message Transfer Agent. Outgoing mail is eventually handed over to an MTA for delivery while the incoming messages are picked up from where the MTA left it (although MUAs running on single-user machines may pick up mail using POP). This Mail Server has been implemented using the programming language JAVA and the facility of Voice Chat is implemented using the Visual Basic Package. The Prerequisites for the mail server are Java Runtime Environment (JRE) 1.3 or higher versions and MS Access 2000 for user info maintenance. The Complete information about the project is provided in the web page http://paradigmintranetmail.tripod.com Website Development for Dr.M.G.R. Deemed University This Project is the creation of a static website for Dr.M.G.R. Deemed university, Chennai with Links related to different Courses such as the Engineering discipline, Dental Sciences, Human Resource and Sciences. Links describing various facilities of teh college including Laboratories, Library, Transportation and various university achievements during the past years. Also the detailed information of all the departments has been furnished. The URL of the Web Site is http://www.drmgrec.ac.in This is a home utility tool which helps in organizing Personal and Official Schedules, Contacts, Reminders. The Organizer tool has a puzzle game implemented in it. The tool can be used by multiple users with separate user profiles maintained for each user with secure authentication for every user to protect his/her data. The password details are being encrypted by using XOR function. The organizer has modern searching facilities based on multiple constraints. The Project is implemented by using the Visual basic 6.0 package with the RDBMS Oracle 9i as the front end. |
