我无法通过 SSH 登录到我的 Debian Wheezy 服务器。
我更改了 ssh_config 和 sshd_config 中的 Ciphers 和 KeyExchange 选项。奇怪的是，我在另外两台相同的机器上进行了相同的更改，却没有遇到任何问题。
幸运的是，我有 VNC 访问权限，可以进入机器进行任何更改。
我现在已将我的 ssh 配置恢复正常，但问题仍然存在：
debug1: Connecting to myserv.com [server_ip] port 443.
debug1: Connection established.
debug3: Incorrect RSA1 identifier

重新启动 SSH 服务后：
sh-4.2$ sudo /etc/init.d/ssh restart
Could not load host key: /etc/ssh/ssh_host_rsa_key
[....] Restarting OpenBSD Secure Shell server: sshdCould not load host key: /etc/ssh/ssh_host_rsa_key
SSH 甚至没有要求我输入密码......
如果有人能帮助我恢复 SSH，我将不胜感激！！

我通过发出以下命令解决了该问题：
sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
出于某种原因，现在一切都正常了。
