# These instructions are for installing Gentoo on Oracle VirtualBox with
# Oracle VirtualBox Extentions installed on the host PC.
# I allocate 1GB during intallation and change to 512KB after competing 
the installation.
# I can still work with 255 KB but slow.

# My local setup is a LAN with several Linux and Win$ boxes with fixed 
IP addresses.
# My local domain name: "itw.lan"
# My Gentoo VM FQDN: "gentoo.itw.lan"
# IP address: 192.168.0.32
# Nameserver-1: 192.168.0.2
# Nameserver-2: 192.168.0.1 (my Router has a very basic build in Name 
Server.)
# Route:	192.168.0.1
# Locale Australia/Brisbane

# Change these at the approbriate places in below text to yours.

# The text without "#" in front are commands to be entered or copied into
# the terminal followed by hitting the Enter Key.


# Preparation:
# Download Gentoo Install CD from:
# 
distfiles.gentoo.org/releases/amd64/autobuilds/current-iso/install-amd64-minimal-20140130.iso

# Configure a Gentoo x86_64 virtual maschine to boot with Gentoo CD.iso 
as CD Drive,
# a virtual 30GB dard drive and Network Adapter as "Bridged Adapter ".

# Boot your new virtual maschine with kernel option "net.ifnames=0".

## type on Gentoo Installer Screen
ifconfig
# write down the IP address and name of your ethernet card like "eth0"

net-setup eth0  #For manual setup if your Router does not have a DHCP 
server.

# Create a password for ssh access.
passwd

time /etc/init.d/sshd start
ping -c 3 google.com

# This completes configiration of the installation system for ssh access 
from a second PC.

# --------------------------------------------

# Open a terminal on your second or Host PC and log by ssh into Gentoo
