Subject: Need help with my logic

Hi Experts,

We have quite a lot of servers but they all are like bellow format

(3 server in a pair)

DK-vk-2.domain.lan
DK-vh-2.domain.lan
DK-vm-2.domain.lan



MK-vk-3.domain.lan
MK-vh-4.domain.lan
MK-vm-3.domain.lan


So basically the different is : k,h,v

Now Problme is :
I need to run a script from one of the server and it will connect to
rest 2 by ssh and will run a command, which i know how to do

but i dont know ,how will i know from which server i am  running and how
to get hostname of the rest 2 servers.
example :

def name_check(name)
         #I Assuming I am running the script from DK-vk-2.domain.lan, So
i need to connect to rest 2 server
         @hostname1 = " DK-vm-2.domain.lan "
         @hostname2 = " DK-vh-2.domain.lan "
  ...................

problem is : i need set the hostname1 and hostname2  Automatically
depends on the server i am running the script.

i can get the hostname of the server by using `hostname`

so it might be
p=`hostname'
puts p
=>DK-vk-2.domain.lan
So if its vk , then rest 2 server will be vm,vh

so the rest of 2 server would be  ,  DK-vm-2.domain.lan ,
DK-vh-2.domain.lan

only differerence is  "m" and "h"


other way round
if i run the script from
DK-vh-2.domain.lan , the other  2 server will be
DK-vm-2.domain.lan
DK-vk-2.domain.lan

CAn any one help me ..

i am quite stuck now ..I would be really grateful if any one can help me
with this

Thanks
