mac 10.11.5 上的 SSH 突然停止工作

Question

SSH 在 mac 10.11.5 上运行良好很长时间了。 安装Ansible 后突然停止工作。 当我尝试连接到远程主机时，我得到的只是 这个。注意：我用一个虚拟的IP地址替换了服务器IP地址。

iMac:~ mohamedsaleh$ ssh -v root@123.456.789.000

更新：我尝试了几台机器，都遇到了同样的问题。

Update2：我尝试过使用 VPN，它工作正常，经过调查，我的 ISP 似乎出于随机原因关闭了该端口。

您可能想要删除本地存储的 ssh 密钥

这是对我有用的快速修复

转到存储 ssh 密钥的目录

cd ~/.ssh/

删除包含您之前使用的所有 ssh 密钥的 known_hosts 文件夹

rm known_hosts

尝试再次连接到您的远程服务器并在出现提示时提供您的密码。
