virtualbox虚拟机中nat和host only的网络“冲突”问题 - Felix021 - narrow streets of cobble stone

Narrow streets of cobble stone. Virtualbox虚拟机中nat和host only的网络 冲突 问题. 2014-10-14 11:26 , IT. 我大约从2010年起，就一直在自己的机器上使用 Windows宿主机 Ubuntu Server@VBox虚拟机 这种组合. 虽然有人说用Bridged Network也能解决这个问题，但是前述方法却有更多好处 首先因为是外网无法直接访问这台机器，所以可以使用弱密码 其次虚拟机里使用NAT通过宿主机访问外部网络，因此像我现在主机上的双网卡的目标网络也可以免配置直接访问。 不过昨天遇到了个问题 貌似以前也曾经遇到过 ，就是突然不能访问外网了 但是仍然能ping通192.168.56.1，即宿主机的Host-Only IP ，经过测试发现如果把Host-Only的网卡去掉就没问题，所以看起来像是这两个网络冲突了。 Sudo route del default.

Narrow streets of cobble stone. 15:11 , IT. 记得很早之前就想给自己的电脑启用BitLocker，但是因为主板上没有TPM芯片 用于存储密钥 ，不能给系统盘加密 而不能给系统盘加密的话，其他盘的解密就需要每次启动系统以后再输入一次密钥，然而我的文档、桌面等一般都存在其他盘，我估摸着会出现一些奇怪的现象，所以就放弃了。 昨天兴起又研究了一下，发现其实并不是一定要有TPM才能给系统盘加密 这个限制是Vista第一次引入BitLocker时的要求，后来微软也意识到，由于大多数民用主板上没有集成TPM芯片，导致BitLocker略显鸡肋，于是在Win7开始做了个变通，允许把加密密钥保存在单独的启动分区里，通过一个密码 或启动U盘 来保证密钥的安全，但是需要在组策略编辑器里将 计算机配置-管理模板-Windows组件-BitLocker驱动器加密-操作系统驱动器-启动时需要附加身份验证 修改为已启用 注意左下角 没有兼容的TPM时允许BitLocker 被打上勾了 ，系统盘被加密后，用户在启动电脑时输入一次密码即可。 09:40 , IT. 2 实测QPS最高的是UClo...
