How do I set up a DNS secondary?

     After you have saved the DNS configurations for 
your DNS domain (the DNS primary), go to the machine 
that you wish to use as a secondary, either by telnet
on a UNIX machine, or by walking up to it in person 
on a non-UNIX machine.  You may create the DNS 
secondary by using the DNS Boss GUI, or by doing the 
eqivalent of these commands from the command line:

mkdir -p /var/opt/DNSBoss/dns_secondary

cd /var/opt/DNSBoss/dns_secondary

ftp name_of_dns_primary_that_has_dnsboss_installed
ftp> cd /var/opt/DNSBoss/dns_build_area

ftp> dir
yourcompany.com

ftp> cd yourcompany.com  
ftp> dir
ftp> get named.boot_for_secondary
ftp> get named.conf_for_secondary
ftp> get db.cache
ftp> get db.127.0.0
ftp> quit

On a SUN, or HPUX machine:
     For Solaris 2.5 and Solaris 2.6 ( Bind 4.x )
          mv named.boot_for_secondary /etc/named.boot
     For Solaris 2.7 or greater ( BIND 8.x, or 9.x )
          mv named.conf_for_secondary /etc/named.conf
     
     For Solaris
          vi /etc/nsswitch.conf
          Make sure the following exists:
          hosts:      files dns
          Save the file.

     reboot

On an SGI 
     chkconfig named on
     uname -r
     If it is 4.X.X.
        mv named.boot_for_secondary 
           /usr/etc/named.d/named.boot
     Otherwise,
        mv named.boot_for_secondary /etc/named.boot
     reboot

     Thats it, you should be done.  The secondary's 
should pull over the latest DNS databases after you
make changes to them.  You do not need to add a 
/etc/resolv.conf on a UNIX machine that is acting as
a DNS primary or secondary.  It automatically know 
how to resolve IP addresses as long as it is 
functioning properly.
     Make sure you test everything.  The nslookup 
command is a great way to do this.  On most Unix 
machines you can type:
nslookup - yoursecondary.yourcompany.com.
> ls -t any yourcompany.com.
This should give you a good idea if you are on track.
