After creating local Unix (AF_UNIX) socket using other program daemon PHP script with function connect() is not able connect to this socket.

'./configure' '--prefix=/usr/local' '--with-system-regex' '--with-apache=/usr/ports/www/apache13-php3/work/apache_1.3.12' '--with-config-file-path=/usr/local/lib' '--disable-debug' '--enable-track-vars' '--with-gd=/usr/local' '--with-zlib' '--with-mysql=/usr/local' '--with-pgsql' '--with-ndbm' '--enable-wddx' '--includedir=/usr/local' '--enable-sockets'

PHP program text:

$sockfd=socket(AF_UNIX, SOCK_STREAM);
connect($sockfd, "/tmp/my_sock.sock");
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this cause the error

FreeBSD program:

main() {

	struct sockaddr_un  serv_addr;
    	int                 addrlen, old_umask;
        int sockfd, ns;

	sockfd=socket(AF_UNIX, SOCK_STREAM, 0);
	unlink("/tmp/my_sock.sock");

	old_umask=umask(0);

    	bzero(&serv_addr, sizeof(serv_addr));
    	serv_addr.sun_family=AF_UNIX;
    	strcpy(serv_addr.sun_path, "/tmp/my_sock.sock");
    	addrlen=sizeof(serv_addr.sun_family)+strlen(serv_addr.sun_path)+1;
    	bind(sockfd, (struct sockaddr *)&serv_addr, addrlen);
    	listen(sockfd, MAX_USERS);
	umask(old_umask);
  	ns=accept(sockfd, (struct sockaddr *)&clnt_addr, &addrlen));
