php – 无法从流氓虚拟机发出出站HTTP请求

例如,在根目录下,当我键入：

curl http://google.com

它失败了消息：

curl: (6) Couldn't resolve host 'google.com'

我不知道是否是防火墙设置,尽管据我所知,我还没有为端口80或其他端口创建任何防火墙规则.

这是我的Vagrantfile的相关部分.如果有任何其他信息,我可以提供,请让我知道在评论：

Vagrant.configure("2") do |config|
  # All Vagrant configuration is done here. The most common configuration
  # options are documented and commented below. For a complete reference,# please see the online documentation at vagrantup.com.


  # Let Vagrant manage the hostname at boot
  config.vm.hostname = "devbox"

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,# accessing "localhost:8080" will access port 80 on the guest machine.
  # config.vm.network :forwarded_port,guest: 80,host: 8080

  # Create a private network,which allows host-only access to the machine
  # using a specific IP.
  config.vm.network :private_network,ip: "10.0.0.10"

  # Create a public network,which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network :public_network

  # Create a public network with a given hardware address.  You can
  # configure your DHCP server (on your router) to assign a particular IP
  # address to the VM.  Update your hosts file accordingly.
  # config.vm.network :public_network,mac: "0a00251010101"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  #config.vm.synced_folder "vagrant/logs","/logs",#  owner: "root",group: "root"

  # Base box to use with Virtualbox provider
  config.vm.box = "debian-7.0.0-amd64-base"
  config.vm.box_url = "http:/mysite.com/debian-7.0.0-amd64-base.box"
