我在Windows Azure中用Ubuntu 14.04镜像创build了一个新的虚拟机。 我试图用ssh连接虚拟机。 但它performance出类似的东西。 你能帮我理解这里出了什么问题吗？
这是terminal的输出。

你的命令（ ssh -v example.cloudapp.net : 22 ）说要连接到example.cloudapp.net ，然后执行命令: 22并退出。
从我所看到的成功做到这一点。
我猜你试图指定端口号（？），但这不是你如何做的。 首先，端口22是ssh的默认端口，所以不需要指定它，但是如果你需要指定端口，使用-p 。
对于一些信息: 22意味着：
$ type : : is a shell builtin $ help : :: : Null command. No effect; the command does nothing. Exit Status: Always succeeds. $
