This is the how-to I am trying to follow.
In i, there is an exampe of lvs_dr init script that configures teh director to
handle requests for nessus....
http://bishop.itsp.purdue.edu/cgi-bin/trac.cgi/file/branches/vsc-2.0/Examples/lvs_dr
and for the nodes configuration :
http://bishop.itsp.purdue.edu/cgi-bin/trac.cgi/file/branches/vsc-2.0/Examples/lvs_dr-node
Can anyone please explain how many ips it is using? I want to understand it but
it is using too many ips for what I don't know. I was hoping this used only
two ips and that is all that i have to work with. With this setup can some1
show an example of how to setup using only two ips: 1. compA 2. compB. I don't
know if this is possible with this setup even....
I was thinking that compA was the director and compB was the node but I don't
know where to get all these ips that they are using i.e. in nodes they have vsc
and director. i thought i was setting up director when i was following lvs_dr
;((
now If i follow this, do I have to follow the how-to on ultramonkey or lvs.org?
Or using this guides helps to set up lvs just fine?

cluser, is the Virtial IP address, that is, the address
that end-users will connect to.
vscan1 and vscan2 are the addresses of the real-servers,
that is, the addresses that the linux-director forwards packets to.
The role of the linux-director, real-servers, and end-users
is covered in the HOWTO. Its also breifly covered here:
http://www.ultramonkey.org/3/lvs.html
The basic principles of LVS are quite simple. It only seems
complex because there are a number of machines and addresses involved.
But if you take the time to understand the basics, then everything
builds on top of that. In other words, there is no magic in there.
