Προβλημα σε client server[SOLVED]

[nrkmaiden]

Θελω να φτιαξω ενα προγραμμα client -server οπως λεει και ο τιτλος που ο πελατης να στελνει ενα μηνυμα στον server για αρχη, αλλα εχω ενα προβλημα ο server δεν εμφανιζει τιποτα απο αυτο που θα επρεπε να εχει διαβασει απο τον πελατη.

 

code:

 

 

server:

int shm_id;
char ans[4];
int i;
for(i=0;i<4;i++){ans[i]=48;}

pid_t pid1;

	 struct sockaddr_un serveraddr;

	 if ((sd = socket(AF_UNIX, SOCK_STREAM, 0)) < 0)
 {
		 perror("server: error while opening socket, exit...");
		 exit(1);
 }
	 serveraddr.sun_family = AF_UNIX;
	 strcpy(serveraddr.sun_path, SOCK_PATH);
	
unlink(SOCK_PATH);
int msgacc;


	 len_address = sizeof(serveraddr.sun_family)+strlen(serveraddr.sun_path);


if(bind(sd,(struct sockaddr *) &serveraddr,len_address)==-1)
	 {
			 perror("server: error in bind. exit...");
			 exit(1);
	 }

/*dimiourgia mias listas pou apothikeuontai oi aitiseis (mikous 1000) mexri
	 na tis e3upiretisei o server*/
			 if (listen(sd, 1000) < 0)
		 {
		 perror("server: listen");
		 exit(1);
		 }
msgacc=accept(sd,(struct sockaddr*) &serveraddr,&len_address);
if(msgacc==-1){
perror("error on accept check clients adress and length\n");}
//atermwn loop gia tin apodoxi/ulopoihsh twn aitisewn apo tous client
while(1)
 {
sleep(6);
printf("afasfa\n");
ns=read(msgacc,ans,5);
if(ns==-1){perror("error read from socket");}
printf("%s\n",ans);
}
return 0;}
