Server with browser

I have coded a server program which interacts with my client, but it doesnt interact with a browser, what could be the problem?
here is the
server.c:

Code:

---

#include <netinet/in.h>
#include <arpa/inet.h>


main(int argc, char *argv[])
{
        int                    sockfd, newsockfd ; /* Socket descriptors */
        int                    clilen;
        struct sockaddr_in      cli_addr, serv_addr;
        int port;

        int i, readsocks;
        char buf[100];          /* We will use this buffer for communication */

        if(argc != 2)  {
                printf("\nEnter port number only in the command line argument\n");
                exit(0);
        }
        if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0) {
                printf("Cannot create socket\n");
                exit(0);
        }
        port = atoi(argv[1]);
        printf("\nport is %d\n", port);
        serv_addr.sin_family            = AF_INET;
        serv_addr.sin_addr.s_addr      = INADDR_ANY;
        serv_addr.sin_port              = port;
        if (bind(sockfd, (struct sockaddr *) &serv_addr,
                                        sizeof(serv_addr)) < 0) {
                printf("Unable to bind local address\n");
                exit(0);
        }

        listen(sockfd, 5);
        clilen = sizeof(cli_addr);
        newsockfd = accept(sockfd, (struct sockaddr *) &cli_addr,
                                        &clilen);
        printf("wow Some client is connected\n\n");
        close(newsockfd);
}

I am using "http://127.0.0.1:8080/" in the address bar of the mozilla firefox.
am running the server program on the same machine on the port 8080.
actually the server should print:

Code:

---

wow Some client is connected

---

but it does nothing..

You've got a connection, but you don't send anything down it - what were you expecting to happen?

if i get a connection.. the server shoul print the line.. it is not printing that means the server has not get any connection..

System Calls or Bust
This suggests you need htons() on the port value.

Also, get Wireshark · Go deep. so you can see what is really happening "on the wire".

Port 8080 is a secure SSL port. The browser is probably trying to make a secured connection and gives up when it doesn't get the correct acknowledgements. Try it on port 80 which is the general HTTP port.

OR... use a different port altogether...

Port 8080 is not "a secure SSL port". 443 is the standard HTTPS port, but any port can actually serve as a secure port if the server is so configured.

To the OP: printf writes to standard output, not to the connected socket. You need to use send(), not printf().

I have changed the code to :

Code:

---

        serv_addr.sin_addr.s_addr      = htonl(INADDR_ANY);
        serv_addr.sin_port              = htons(port);

---

still not working.
The client program now also is unable to connect to the server:
here is the client program.

Code:

---

#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <arpa/inet.h>

main(int argc, char *argv[])
{
        int                    sockfd ;
        struct sockaddr_in      serv_addr;

        if(argc != 3)  {
                printf("\nEnter SERVER_IP & PORT_NUMBER only in order as command line argument\n");
                exit(0);
        }


        if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0) {
                printf("Unable to create socket\n");
                exit(0);
        }
        serv_addr.sin_family            = AF_INET;
        serv_addr.sin_addr.s_addr      = inet_addr(argv[1]);
        serv_addr.sin_port              = atoi(argv[2]);
        if ((connect(sockfd, (struct sockaddr *) &serv_addr,
                                                sizeof(serv_addr))) < 0) {
                printf("Unable to connect to server\n");
                exit(0);
        }
}

I think any port number can be used if it can be bind by the server program.

I want to connect this client program too, and make the server work with browser too.

I am not using send but write just to check weather there is any connection has been established or not as accept() call blocks the process till there is any connection made.
