Bug Description

最近将局域网服务器的ssh代理到互联网，比较疑惑出现了一些莫名的大量失败连接尝试。连接服务器后会显示如下：
Last failed login: Fri Oct 22 08:20:32 CST 2021 from localhost on ssh:notty
There were 25066 failed login attempts since the last successful login.

个人猜想有两种可能性：
1.把ssh暴露在了互联网，而且frps端服务器没有开启端口的访问白名单，导致一些黑客程序有大量的连接尝试，出现上述问题；
2.frp代理ssh可能会出现这种情况吗？当然我个人认为不会呀。

如果是第一种的话，那么我就必须得在frps端做一些策略了。
