Question Need to setup floating IP
Hi,

Below is the Theory that I need to implement.

Code:
Load balancing websites can be achieved by putting 2 entries in your DNS, for instance:

www.example.com 192.168.1.1
www.example.com 192.168.1.2

then DNS will do a round Robin between them, but should either host fail then your will see intermittent loss when surfing, as the DNS will still point to either IP in turn.

If you want failover, for instance:

host1.example.com 192.168.1.1 (master)
host2.example.com 192.168.1.2 (slave)

and the floating ip as you call it

float.example.com 192.168.1.3

Then you would need scripts that run as often as you can on slave, to see if master is still there (sometimes referred to as a heartbeat).

if the Master drops, then it needs run a script to bring the floating ip up on the slave to resume service.

A Google search for heartbeat, failover should yield somehow to on the subject.

I have two HPUX boxes with each having one network card.

Can someone please help me provide the steps inorder to setup a floating IP on my system.

Please keep it detailed as I am naive.

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
