我部署了一个现代蜂蜜网用于课程项目。我有一个托管 MHN 服务器的 Ubuntu Box，现在我部署了一个 Ubuntu 14.04 盒来托管几个传感器（Cowrie、Snort 等）。然而，在 ssh 暴力破解测试之后，我再也无法登录到我的 Ubuntu 盒。
Putty 和 Linux 终端都表明 Ubuntu Box 现在Using keyboard-interactive authentication即使使用正确的用户名和密码，我也无法登录。
我尝试过复制并传递密码、手动输入密码、尝试从不同的 IP 地址登录等。目前我还没有采取任何防御措施（fail2ban、denyhosts等）。没有设置 SSH 密钥，我也不想设置。只有密码验证。
以下是 ssh -v 的输出：
