我在 Windows Azure 中使用 Ubuntu 14.04 映像创建了一个新的 VM。我尝试使用 ssh 连接 VM。但它显示类似以下内容。您能帮助我了解这里出了什么问题吗？
这是终端的输出。

答案1
您的命令（ssh -v example.cloudapp.net : 22）表示连接到example.cloudapp.net然后执行命令: 22并退出。
据我所见，它成功做到了这一点。
我猜你尝试指定端口号（？）但你没有这样做。首先，端口 22 是 ssh 的默认端口，因此无需指定它，但如果你需要指定端口，请使用-p。
有关含义的一些信息: 22：
$ type :
: is a shell builtin
$ help :
:: :
Null command.
No effect; the command does nothing.
Exit Status:
Always succeeds.
