OSX ssh：[IP]关闭了连接

因此，当我尝试从我的一台Mac SSH切换到另一台Mac时，如下所示：

ssh root@macpro.local

我得到：

Connection closed by 192.168.1.64

我试过了：

ssh -vvv root@macpro.local

并获得：

有任何想法吗？？？

看起来ssh服务器未接受ssh客户端要使用的身份验证类型。或通常不允许该根用于ssh访问。查找解决方案的更好方法是访问ssh服务器上的ssh.log。在那里，您会找到详细的信息，为什么拒绝建立连接。

不久前我遇到了类似的问题，这对我有所帮助：https : //discussions.apple.com/thread/3008731

tl; dr：文件/ etc / ssh_host_dsa_key的权限应为700，否则ssh连接将失败。

修理：

sudo chmod 700 /etc/ssh_host_dsa_key
