Go4Expert - Help needed in echo server program

hey i fixed up my previous echo server program but now i am facing problems in recv() function..

This program successfully sends "Hiii!!!!" to the client .

But is not receiving properly ..
I telneted the program to test
and when i send a message from telnet to this program .

It is showing some:-
"libc.so.6"

on the screen

why this is happening ..
Help me with this.

Here is the new source code:-

Code:

/* A simple server in the internet domain using TCP

   The port number is passed as an argument */

#include <stdio.h>

#include <sys/types.h> 

#include <sys/socket.h>

#include <netinet/in.h>

#include<arpa/inet.h>

#include<netdb.h>

#include<string.h>



#define portno "4040"



int main()

{

        struct addrinfo hints,*serv,*p;

    int sockfd,newfd,status;

    struct sockaddr_storage their_addr;

    socklen_t addr_size;

    char *msg;

    int len;

    char buff[100];



    memset(&hints,0,sizeof(hints));

    hints.ai_socktype=SOCK_STREAM;

    hints.ai_family=AF_UNSPEC;

    hints.ai_flags=AI_PASSIVE;



    if((status=getaddrinfo(NULL,portno,&hints,&serv)) == -1)

    {

        fprintf(stderr,"Error in getaddrinfo :-\n %s\n",gai_strerror(status));

    }



    for(p=serv;p!=NULL;p = p->ai_next)

    {

        if( (sockfd = socket(p->ai_family,p->ai_socktype,p->ai_protocol)) == -1 )

        {

            printf("Error in Socket \n");

            continue;

        }

        

        if( bind(sockfd,p->ai_addr,p->ai_addrlen) == -1)

        {

            printf("Binding error!!!\n");

            close(sockfd);            

            continue;

        }

        

        break;

    }



    /* if( (connect(sockfd,serv->ai_addr,serv->ai_addrlen) ) == -1 )

    {

        printf("Connect err!!!\n\n");

        return(0);

    }  if on client we use this*/



    listen(sockfd,10);



    addr_size= sizeof(their_addr);

    newfd = accept(sockfd, (struct sockaddr *)&their_addr,&addr_size);

    

    

        printf("%s",msg);

        

        if( ( send(newfd,"Hiii!!!!",9,0) ) == -1)

        {

            printf("err in send\n\n");

            return(1);

        }

    

    recv(newfd,buff,sizeof(buff),0);

    printf("\n");

    freeaddrinfo(serv);

    close(sockfd);

    return(0);

}
