Vagrant Connect
vagrant可以共享到vagrant环境的任何或每个端口，而不仅仅是SSH和HTTP。“vagrant connect”命令为连接人员提供一个静态IP，他们可以使用该IP与共享的vagrant环境通信。发送到此IP的任何TCP流量都被发送到共享的vagrant环境。
1.Usage
即调用vagrant share --full命令
这将自动为远程连接共享尽可能多的端口。更多信息请查看 页面。
注意在调用vagrant share --full命令末尾的共享名字，并将其提供给希望连接到你的机器的人。他们只需要简单地调用vagrant connect NAME命令即可（和上一篇ssh的连接方法一样）。这将给他们一个静态IP，他们可以使用它来访问你的vagrant环境。

2.How does it work?
vagrant connect的运行是通过做vagrant最擅长的事情:管理虚拟机来实现的。vagrant connect使用VirtualBox或VMware(更多的提供者支持即将到来)创建了一个只占用20 MB内存的小型虚拟机。
然后，发送到这个小型虚拟机的任何流量都被代理到共享的vagrant环境，就好像它被定向到这个环境一样。
$vagrant connect budget_hello:agenda_design
3.Beware: Vagrant Insecure Key
如果你正在使用的vagrant环境或box是受到vagrant不安全密钥对(大多数公共box都是)的保护，那么连接到SSH的任何人都可以轻松地使用SSH。
虽然你希望与你信任的人共享，但在某些环境中，你可能与类或conference共享，并且不希望它们能够SSH进入。
在这种情况下，我们建议从vagrant计算机中更改或删除不安全的密钥。最后，我们要注意，我们正在努力使之在使用vagrant share时，除非显式允许，否则vagrant私钥将被主动拒绝。但是，这个特性还没有完成。
