Hahaha its still not working..

The client side
Code:
while(1){

   int ret;
   char country[300];


   printf("Please enter country name > ");

   scanf("%s",country);

   if (strcmp(country, "exit") == 0)
   break;
   else
   ret = write(clientFd,country,strlen(country));
   //f (ret == -1) perror("write");
   //printf("Write returned: %d\n", ret);    

   

   //write(clientFd,country,strlen(country));

   }

Server Side

Code:
readData();

            bzero(country,300);

            c=read(clientFd,country,300);

	    printf("You have entered: %s\n",country);

            printf ("%s Capital       : %s\n", country,getCapital(country));

            printf ("%s Currency Code : %s\n", country,getCurrencyCode(country));

            char* capital = getCapital (country);

	    char* currency = getCurrencyCode(country);



            close (clientFd); /* Close the socket */

            exit (/* EXIT_SUCCESS */ 0); /* Terminate */

So like what you all said it might be the reading part that is the the problem.
From what I think is just the read problem?
Reason is I comment the write link it just run the loop normally.

sctp_peeloff

SCTP_PEELOFF(3) 					     Linux Programmer's Manual						   SCTP_PEELOFF(3)

NAME

       sctp_peeloff - Branch off an association into a separate socket.

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_peeloff(int sd, sctp_assoc_t assoc_id);

DESCRIPTION

       sctp_peeloff  branches  off  an	existing association assoc_id on a one-to-many style socket sd into a separate socket. The new socket is a
       one-to-one style socket.

       This is particularly desirable when, for instance, the application wishes to have a number of  sporadic	message  senders/receivers  remain
       under  the  original  one-to-many  style socket, but branch off those assocations carrying high volume data traffic into their own separate
       socket descriptors.

RETURN VALUE

       On success, the new socket descriptor representing the branched-off asociation is returned.  On error, -1 is returned,  and  errno  is  set
       appropriately.

ERRORS

       EBADF  sd is not a valid descriptor.

       EINVAL The assoc id passed is invalid or if the socket is a one-to-one style socket.

       ENOTSOCK
	      Argument is a descriptor for a file, not a socket.
