Troubleshoot Ubuntu ping Gateway destination Host unreachable Error

Ifconfig Check the configuration, no problem, is OK,

Check the firewall, it's closed, damndest, what's the problem?

All kinds of attempts, finally, the IP into automatic acquisition can be ping through, but why not manually set it?

Finally read this friend's article http://my.oschina.net/kevinvane/blog/354314

Just woke me up, I also installed a VirtualBox, the original is a virtual network card conflict, the VirtualBox deleted, OK

Ps:virtualbox I feel not very stable ah (sometimes abnormal shutdown after the normal), although VMware compared to eat resources, but others are really strong, so we recommend that you use VMware, now the latest version of 14 with VMware Tools, display is also more meticulous than before, very good
