Fixed typo.

INSTALATION
-----------

Only manual installation of this script is supported. You must know, what you
are doing. Here is little HOWTO:

Copy files 'switchconfig' into /etc/init.d/ directory:

------------------------%<------------------------
cp switchconfig /etc/init.d/
mkdir /etc/default/
cp default-switchconfig /etc/default/switchconfig
------------------------%<------------------------

Create symlink in /etc/rcS.d/ directory:

---------------------%<---------------------
cd /etc/rcS.d/
ln -s ../init.d/switchconfig S46switchconfig
---------------------%<---------------------

Maybe, you must change "S46" number of start script into right value. I have
renamed standard Debian symlinks (I'm using Debian unstable), because there
was no place for firewall and switchconfig script. A situation in my
/etc/rcS.d/ now is:

--------------------------------------%<--------------------------------------
# root@twinky: ls -la /etc/rcS.d/

--------------------------------------%<--------------------------------------

Yes, switchconfig script must be started after networking script and it is
good start also firewalling script between networking and switchconfig script.
Please, think about this. ;-)

Now you can configure your networks. If you wish configure 2 networks, e.g.
budkova.zoznam.sk and intranet.sk, create following directories:

----------------------%<----------------------
mkdir -p /etc/switchconfig/_default/
mkdir -p /etc/switchconfig/budkova.zoznam.sk/
mkdir -p /etc/switchconfig/intranet.sk/
----------------------%<----------------------

Note: /etc/switchconfig/_default/ directory is required and is contains config
files, if no networks was detected.

These directories are now root directories for your config files, which needs
to be different in your networks.

Assume, you will change configuration of your apache webserver. In home
network you will allow access to your holliday photos, but not in your comapny
network. Simply type:

-------------------------%<-------------------------
/etc/init.d/switchconfig add /etc/apache/httpd.conf
-------------------------%<-------------------------

and your config file will be placed into /etc/switchconfig/*/
directories. On startup, correct symlink from /etc/apache/httpd.conf to
/etc/switchconfig/<your_current_network>/etc/apache/httpd.conf will be
created.

Now you can configure your apache webserver for home and company network in
these files:

----------------------------%<----------------------------
/etc/switchconfig/intranet.sk/etc/apache/httpd.conf
/etc/switchconfig/budkova.zoznam.sk/etc/apache/httpd.conf
----------------------------%<----------------------------

You can add also other config files. It depends only on your fantasy. ;-)

WARNING: make backup of your config files, because you can damage these files
during your experiments !!!


Now you must configure network detecion algoritmus. This can be configured in
/etc/default/switchconfig config file. Example:

---------------------%<---------------------
DOMAIN_ORDER="budkova.zoznam.sk intranet.sk"

SERVER_budkova_zoznam_sk="192.168.0.107"
SERVER_intranet_sk="192.168.0.1"
---------------------%<---------------------

Domains (networks) are detected in order, as specified in DOMAIN_ORDER
variable. In this example I have choosen IP address 192.168.0.107 for domain
'budkova.zoznam.sk', because this IP address is not available in my home
network 'intranet.sk'. Therefore 'budkova.zoznam.sk' domain is detected first.

If you wish add next network, create variable as follows:

--------------------%<--------------------
SERVER_your_next_domain_com="192.168.0.60"
--------------------%<--------------------

for domain 'your.next.domain.com'.
