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.

Floating Point Division

Does anyone have a simple way of doing floating point ("fp") division? For example, if I divide 3 by 5, I can get 0.6. The built-in calc (`bc`) will perform fp multiplication, but not division, at least not straight-up (i.e., starting bc and just typing in 3/5). I am trying to do this using...

What is floating IP

Hi, I need to understand the concept of floating IP and how can I get it working on my system. I am using Itanium boxes. I am naive so please help me from the very basics.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
