What difference does that make? Oh, really! My dear, ssh!

那又怎样？别这样 亲爱的！

We can check that these two files are now under ssh.

我们可以检查这两个文件现在位于 ssh 下。

Like a baby.- That's not true. He's a snorer. Hey, ssh.

睡得可死了 -说瞎话 他打呼噜。

It's we can use something called " SSH keys" .

我们可以使用一种叫做“SSH 密钥”的东西。

You cannot use " CP" but you can use " SCP" , for " SSH copy" .

您不能使用“CP”，但可以使用“SCP”，用于“SSH 复制”。

Ah, because I don't have my own ssh config, yeah.

啊，因为我没有自己的 ssh 配置，是的。

And now, if we try to SSH, we can SSH without actually typing any key at all, or any password.

现在，如果我们尝试使用 SSH，我们无需实际输入任何密钥或任何密码即可进行 SSH。

And if I copy this, this is right now in my local folder, I can copy this into ssh.

如果我复制它，它现在就在我的本地文件夹中，我可以将其复制到 ssh 中。

And by doing that, it's grabbing all that configuration from the SSH config and applying it here.

通过这样做，它会从 SSH 配置中获取所有配置并在此处应用它。

Right now I don't have any SSH keys, so I'm gonna create a couple of them.

现在我没有任何 SSH 密钥，所以我要创建几个。

One of the other things to know about SSH is that the equivalent of the dot file for SSH is the " SSH config" .

关于 SSH 需要了解的另一件事是，与 SSH 的点文件等效的是“SSH 配置”。

Now, instead of having to do this really long command, I can just say I just want to SSH into the host called VM.

现在，我不必执行这个很长的命令，我只需说我只想通过 SSH 连接到名为 VM 的主机。

That would be... so for example, if you're in an SSH connection and you close the connection, that is the hang-up signal, SIGHUP, which I'm gonna cover in an example.

那就是… … 例如，如果您处于 SSH 连接中并且关闭了连接，则这就是挂断信号 SIGHUP，我将在示例中介绍它。

If that command seemed a little bit janky, you can actually use this command that is built for this, so you don't have to kind of craft this " ssh t" command.

如果该命令看起来有点笨拙，您实际上可以使用为此构建的命令，因此您不必编写此“ssh t”命令。

SSH keys just use public key encryption to create a pair of SSH keys, a public key and a private key, and then you can give the server the public part of the key.

SSH 密钥只需使用公钥加密来创建一对 SSH 密钥，即公钥和私钥，然后您可以将密钥的公共部分提供给服务器。
