我有一个 PivosXios-DS-M3 XBMC-Box，直到昨天才运行 xbmc12。我所有的桌面都运行 Archlinux。
昨天，我在 Pivos-box (Kodi 14.1) 上全新安装了 tofu-linux。
因此，在我的 arch 机器上，我需要删除 ~./ssh/known_hosts.
虽然“其他一切”都有效，例如浏览 Pivos IP 网页、通过 FTP 连接到盒子等，但我无法再通过 ssh 登录。
我的 Pivos-box 有 IP 192.168.0.150 ，这就是我得到的：
$ ssh [email protected]
> Connection closed by 192.168.0.150
系统不会询问我是否要添加新的主机密钥known_hosts（ssh 在连接到新机器时总是这样做）。
$ ssh -vvv [email protected]

我安装了 Firefox-SSH-Plugin (FireSSH)，并且可以使用该插件连接到我的盒子。插件询问是否应将新的主机密钥添加到known_hosts，我回答为“ yes”。
由于密钥现在写在 中.ssh/known_hosts，我也可以通过终端上的 ssh 连接到我的盒子。

# 3. system-wide file
# Any configuration value is only changed the first time it is set.
