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.

efax-gtk-socket-client

efax-gtk-socket-client(1)				      General Commands Manual					 efax-gtk-socket-client(1)

NAME

       efax-gtk-socket-client - a client of efax-gtk to work with lpd/lprng

SYNOPSIS

       efax-gtk-socket-client [hostname] [port]

DESCRIPTION

       This program enables lpd/lprng to access the efax-gtk socket server. Meaning the user can send faxes to a printer, which will ack as a fax.

       It  takes  two arguments - first a hostname to connect to, and secondly a port number at that hostname to connect to.  All efax-gtk-socket-
       client does is to read from standard input (in this case from lpd/lprng) and passes it to a socket at the hostname and port  number  passed
       as arguments to it (namely the hostname of the computer efax-gtk is running on - normally you would specify localhost - and the port number
       of the socket).

       fax:
	    :sd=/var/spool/fax:
	    :mx#0:
	    :sh:
	    :lp=/dev/null:
	    :if=/var/spool/fax/efax-gtk-faxfilter:

       This will cause a printer by the name of "fax" to be available, which (if printed to) will send the file to the efax-gtk socket server.	If
       you  set  efax-gtk  to  listen on a port other than port 9900, you will need to amend the file /var/spool/fax/efax-gtk-faxfilter by hand to
       specify the correct port number on which efax-gtk is listening.

       Don't forget to restart the lpd printer daemon after amending /etc/printcap.

OPTIONS

       [ hostname ] - The name of the host to listen to. Usually should be locahlhost.
       [ port ] - the port number to listen to on the [ hostname ].
