mammoth's Private IP Setup
Supports: CentOS 6 (32-bit and 64-bit), 7 (64-bit); Debian 7.0 (32-bit and 64-bit), 8 (64-bit); Ubuntu 10.10 (32-bit), 12.04 LTS/14.04 LTS (32-bit and 64-bit)
Overview
Each Mammoth VPS comes with access to the LAN via a private IP, which enables unmetered VPS-to-VPS data transfers. However the private IP is not setup by default.
This script will add your VPS' private IP to its network configuration so that the internal LAN can be used.
