FTP连接不了 要命

[careers1111]

public static void main(String[] args){
FtpClient ftpClient=new FtpClient();
try {
ftpClient.openServer("192.168.0.66");
ftpClient.login("root","careers");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

自己写的FTP连接

先保证使用ide通过那个用户名和密码能连接192.168.0.66的端口21，
再用一下试试：
FtpClient ftpClient=new FtpClient("192.168.0.66",21);
ftpClient.login("root","careers");

你首先在本机上连接试试，能不能连接上

在地址栏： ftp://192.168.0.66:21 输入用户名和密码

ftp分主动和被动模式，好好看一下防火墙。仔细解释太麻烦，看看书吧、
