README for "where2-fc1.sh" shell script
===========================================


PURPOSE OF SCRIPT

A portable PC typically needs to operate in multiple
networking environments, e.g. home, office, friend's home...
Each of these environments has its own unique settings for

	hostname / hosts
	device IP addresses
	gateway device/address
	DNS
	interfaces (eth0, eth1, rfcomm0...).

This script allows you to switch networking settings between two different locations, for example, home and office.
It can easily be extended to cover more locations if required.

Because the hostname will most likely need to change between locations, a full shutdown is required (at least I have not found a way of doing it "on the fly" without serious host misconfiguration..!).  The script will perform this for you.

You will need to know exactly the network settings for home and office before 
going any further.  Make sure you have a working configuration for each.  Print 
out the contents of each of the following files, first when you are working at 
home, then when you are working at the office:

	/etc/sysconfig/
		file: network
	/etc/sysconfig/networking/profiles/default/
		files: ifcfg-eth*, keys-* (if wireless networking is used), hosts, network, resolv.conf


Create two additional files for /etc/sysconfig/network:

	/etc/sysconfig/network.home
	/etc/sysconfig/network.office

Edit network.home so that it contains the settings appropriate to your home network.
Edit network.office so that it contains the settings appropriate to your office network.

Create two new directories:

	/etc/sysconfig/networking/home   and
	/etc/sysconfig/networking/office

Copy all the files from /etc/sysconfig/networking/profiles/default/ into /etc/sysconfig/networking/home/
Edit them according to your home networking settings (from the printouts you made previously).

Copy all the files from /etc/sysconfig/networking/profiles/default/ into /etc/sysconfig/networking/office/
Edit them according to your office networking settings (from the printouts you made previously).

You should now have all the required files.  If not, you will get error messages
when you run "where2-fc1.sh".

RUNNING THE "where2-fc1" SCRIPT (MUST BE RUN su root)

Simply cd to the directory where the script is stored, and enter:

	sh where2-fc1.sh

If you have problems, make sure you have read and implemented everything above
before contacting me!  However, I may have missed out something important, so
all feedback will be appreciated.
