OBJECTIVE To develop a user friendly Editor to support multi-platform and to overcome the drawbacks faced by Telnet. To develop a user friendly Editor to support multi-platform and to overcome the drawbacks faced by Telnet. Telnet is a protocol for connecting a Remote System. Telnet is a protocol for connecting a Remote System. Connection is made by providing a IP address for connection. Connection is made by providing a IP address for connection.

Drawbacks of Vi Editor  Vi Editor has 3 Modes of operation viz., Insert Mode Command Mode Visual Mode  To edit a text in Vi Editor the modes have to changed accordingly.  Its hard to remember the commands of Vi Editor

About our Editor This editor is a GUI based Editor This editor is a GUI based Editor User friendly User friendly Supports multi-platform Supports multi-platform Good Interface for Telnet Good Interface for Telnet

Modules Our Project comprises of 10 Modules: 1. 1.Connection 2. 2.Security System 3. 3.Command Processing 4. 4.Backup Manager 5.File Transaction 6.Mail Service 7.Memory Control 8.Search Engine

SYSTEM ANALYSIS

The use of Telnet is to connect clients with it Remote machine (Linux Server). The server sends the request given by the client and gets The core area of this project is to overcome the drawback faced by the Telnet.

PROBLEM DEFINITION The existing vi editor has modes named insert mode and command mode used to type a program, to save, to delete etc., really working in this editor becomes tedious, and it will give headaches to the clients. The existing vi editor has modes named insert mode and command mode used to type a program, to save, to delete etc., really working in this editor becomes tedious, and it will give headaches to the clients. The program which we have developed in C helps us to communicate with the editor. The program which we have developed in C helps us to communicate with the editor.

SOCKET Socket( ) is the end-end connection between the systems. Socket( ) is the end-end connection between the systems. Syntax: int socket(int domain, int type, int protocol); 1. Domain is set as "AF_INET“. 2. Type argument specifies the kernel of the socket “SOCK_STREAM”. 3. Protocol to "0". Syntax: int socket(int domain, int type, int protocol); 1. Domain is set as "AF_INET“. 2. Type argument specifies the kernel of the socket “SOCK_STREAM”. 3. Protocol to "0".

BIND Bind( ) method associates the socket with a port on the client machine. Bind( ) method associates the socket with a port on the client machine. Syntax: int bind(int sockfd, struct sockaddr *my_addr, int addrlen); 1. sockfd is the socket file descriptor returned by socket( ). 2. my_addr is a pointer to a struct sockaddr that contains information about your address, namely, port and IP address. 3. addrlen can be set to sizeof(struct sockaddr). Syntax: int bind(int sockfd, struct sockaddr *my_addr, int addrlen); 1. sockfd is the socket file descriptor returned by socket( ). 2. my_addr is a pointer to a struct sockaddr that contains information about your address, namely, port and IP address. 3. addrlen can be set to sizeof(struct sockaddr).

CONNECT Connect( ) is used to connect the remote host from the server. Connect( ) is used to connect the remote host from the server. Syntax: int connect(int sockfd, struct sockaddr *serv_addr, int addrlen); 1. sockfd is the socket file descriptor,returned by the socket( ) call. 2. serv_addr is a struct sockaddr containing the destination port and IP address. 3. addrlen can be set to sizeof(struct sockaddr). Syntax: int connect(int sockfd, struct sockaddr *serv_addr, int addrlen); 1. sockfd is the socket file descriptor,returned by the socket( ) call. 2. serv_addr is a struct sockaddr containing the destination port and IP address. 3. addrlen can be set to sizeof(struct sockaddr).

LISTEN Listen( ) waits for incoming connections and handle them appropriately. Listen( ) waits for incoming connections and handle them appropriately. Syntax: int listen(int sockfd, int backlog); 1. backlog is the number of connections allowed on the incoming queue i.e. the incoming connections are going to wait in this queue until the accept( ) fires. Syntax: int listen(int sockfd, int backlog); 1. backlog is the number of connections allowed on the incoming queue i.e. the incoming connections are going to wait in this queue until the accept( ) fires.

SEND & RECIEVE These two functions are for communicating over stream sockets or connected datagram sockets. These two functions are for communicating over stream sockets or connected datagram sockets. Syntax: int send(int sockfd, const void *msg, int len, int flags); int recv(int sockfd, void *buf, int len, unsigned int flags); Syntax: int send(int sockfd, const void *msg, int len, int flags); int recv(int sockfd, void *buf, int len, unsigned int flags);

sockfd is the socket descriptor where data is to be sent. sockfd is the socket descriptor where data is to be sent. msg is a pointer to the data you want to send. msg is a pointer to the data you want to send. len is the length of that data in bytes. len is the length of that data in bytes.
