stateless server and nslookup

A stateless Linux server is a centralized server in which no state exists on
the single workstations. There may be scenarios when a state of a partilcuar
system is meaningful (A snap shot is taken then) and the user wants all the
other machines to be in that state. This is where the stateless Linux server
comes into picture.

Features:

    * It stores the prototypes of every machine
    * It stores snapshots taken for those systems
    * It stores home directories for those systems
    * Uses LDAP containing information of all systems to assist in finding
out which snapshot (of state) should be running on which system.

 I am not sure about stateless Linux server but you please check is it
correct.



Non-interactive mode in nslookup


*Nslookup* is a program to query Internet domain name servers. *Nslookup *has
two modes: interactive and non-interactive. Interactive mode allows the user
to query name servers for information about various hosts and domains or to
print a list of hosts in a domain. Non-interactive mode is used to print
just the name and requested information for a host or domain.
