Slave DNS Server: what the significance of sh make-localhost ?

[kkchn sms]

Peopel ;
  I am setting up a Slave DNS server for my DNS server :

Question 1:

is it needed to run     sh makeloaclhost    , if I am setting up a slave DNS
server ?


2  I have a basic doubt  :

Whats the significance of  sh make-localhost  : both in Primary DNS and
slave DNS  servers ?

Thanks in Advance
