Finger的问题？ ( 积分: 10 )

skt:=socket(AF_INET,SOCK_STREAM,0);
if(skt=INVALID_SOCKET)then
begin
memInfo.Lines.Add('Error:Create socket failed!');
exit;
end;
//3.连接主机
ZeroMemory(@addr,sizeof(addr));
addr.sin_family :=AF_INET;
addr.sin_addr.s_addr :=inet_addr(Pchar('192.168.42.1'));
//Finger use #79 port
addr.sin_port:=htons(79);
Re := connect(skt,addr,sizeof(addr));

怎么会连接不上本机呀?
