如何向我知道IP地址的电脑发送短信？
我知道这是一个奇怪的问题，但我想知道是否有办法向我知道 IP 地址的 PC 发送短信。
例如，我正在通过 torrent 从网络上的 PC 下载文件。
通过 torrent 我可以知道这台电脑的 IP 地址，并且我想向拥有这台电脑的人发送短信。
这可能吗？
I know this is a weird question, but I would like to know if there is a way to send a text message to a PC whose IP address I know.
For instance, I am downloading a file through torrent from a PC on the net.
Through torrent I can know the IP address of this PC, and I want send a text message to the person who owns this PC.
Is this possible?

答案是否定的。您必须通过收件人 PC 上的开放端口来发送该端口，而防火墙肯定会阻止该端口（Windows 防火墙、路由器等）。即使它没有被阻止 - 您也需要一些东西来将消息从零和一转换为文本 - 并将其显示在用户监视器上。您需要编写一个软件客户端来执行此操作，并让该人安装它。
可能有一些黑帽技术可以做到这一点，但同样，您谈论的是高级软件和网络渗透。
The answer is No. You would have to send that through an open port on the recipients PC which a firewall would surely block (Windows Firewall, router, etc..). Even if it didn't get blocked - you'd need something to turn your message from zeros and ones to text - and display it on the users monitor. You'll need to write a software client to do that, and get that person to install it.
There are probably some black-hat techniques to do this, but again, you're talking advanced software and network penetration.
