我们使用Vagrant和Ansible来configurationVirtualBox机器。
它工作的很好，但最近我们开始遇到一些需要访问互联网的任务的奇怪的networking问题，如apt-get update ， composer update ， gem install等。这些问题不时出现，它们是不稳定。 有时它不能连接到某个服务器或域名不解决。
有趣的是，当我通过SSH（ vagrant ssh ）连接到盒子本身并手动发出这样的命令时，例如sudo apt-get update; sudo apt-get dist-upgrade sudo apt-get update; sudo apt-get dist-upgrade – 它一直在正常工作。
以下是NPM的示例错误：

我们正在使用以下框：
http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-i386-vagrant-disk1.box
主机操作系统是Ubuntu 14.04 。
我们在不同的networking（不同的城市）遇到这种问题。
这可能是什么原因？ 我们如何debugging并修复它？
Vagrantfile：
# -*- mode: ruby -*- # vi: set ft=ruby : # "2" is an API version here. Vagrant.configure("2") do |config| config.vm.box = "trusty32" config.vm.box_url = "http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-i386-vagrant-disk1.box" config.vm.hostname = "wa.local" config.vm.network "private_network", ip: "192.168.2.2" # Using NFS for now, cause native sharing is broken config.vm.synced_folder ".", "/vagrant", nfs: true # Provisioning config.vm.provision "ansible" do |ansible| ansible.host_key_checking = false ansible.inventory_path = "ansible/inventory.ini" ansible.playbook = "ansible/vagrant.yml" ansible.limit = "all" end # Provider Configuration: VirtualBox config.vm.provider :virtualbox do |vb| # Setting RAM to 1 GB vb.memory = 1024 vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"] end end
问题现在已经消失了。 我仍然不知道为什么发生在第一位。 也许我最近添加到Vagrantfile中的行vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]帮助。
感谢所有的build议！
你有没有可能导致问题的入侵防御设备或防火墙？ 我见过自动化方法触发机器人的规则。 许多连接可能会被误解为端口扫描，powershell尝试等等。然后，IDS / IPS /防火墙将开始丢弃数据包，导致奇怪的事情失败，没有任何明确的逻辑为什么。 这些规则不会在您手动执行时触发，所以在您排除故障时一切都很顺利。
