c - recv()/read() in client never terminates -

i'm trying implement client receives , sends data from/to server. however, while sending works, receive never , program hangs there.

this bare bones problem area without error checking.

    //send data     char* message = "list\n";     write(sockfd, message, 5);      //receive data     int numbytes;     char buf[100];     if ((numbytes = recv(sockfd, buf, 99, 0)) == -1) {         perror("recv");         exit(1);      }     buf[numbytes] = '\0'; 

i tried insanely basic-

//send data char* message = "list\n"; write(sockfd, message, 5);  //receive data char* buf = calloc(1, 100); read(sockfd, buf, 7);        //the message i'm supposed receive 7 bytes, tried 6 , 8 account nulls etc 

this hangs @ read too.

edit: terminates after added

shutdown(sockfd, 1); 

after send data part, while response should

ok\n7 try.txt 

the response

ok
