Problem

I configured /etc/network/interfaces wrongly so that I cannot access the server. The problem is that the server is using NIS and NFS which needs a network, and which means it cannot fetch any user information from the master server or mount the file system. I can boot server or use usb port or whatever. I can physically use the server machine.

Question

Is there any way to access to the server? Should I reinstall the Ubuntu server?

Solution

Okay, I've got an answer. If you can use a physical machine, you can access to the shell as the root through "ubuntu recovery mode" which shows up while booting on the grub.

Boot into single user mode as root from GRUB and correct your config.
