我在 SSH 连接到 Sonicwall 设备时遇到了一个奇怪的错误，我无法解决。该问题似乎只发生在 OS X (10.11) 的内置 SSH 上。我可以从 OS X 以外的各种设备成功 SSH 到防火墙。
我看到的错误是：ssh_dispatch_run_fatal：连接到 xxxx 端口 22：密钥类型不匹配
尝试理解这一点，但没有任何收获。这是使用 -vvv 时的输出。

我尝试使用 brew 安装较新版本的 ssh，即 OpenSSH_7.2p2 版本。但也没有成功。
谁能向我解释这里出了什么问题？
答案1
事实证明，这确实是 Sonicwall 上的一个有缺陷的固件。如果您运行的是 6.2.2.2-19n，请注意，该问题专门与此版本有关。升级到 6.2.5.1 解决了这个问题。
