Hello all,
Can someone direct me where to go to find out example of how to create a script 
using nsupdate from CLI to add host to forward and reversing zone of DNS?
I am new to Unix and just installed my freeBSD box which running apache and 
BIND last month.

Any advise or information will be highly appreciated.

In your named.conf you have eg:

        zone "example.com" {
                type master;
                file "dynamic/db.example.com";
                allow-update { key host1.example.com.; };
        };
        key "host1.example.com." {
                algorithm hmac-md5;
                secret "XXXX...XXXX==";
        };

and on host1 you use this script:

#!/bin/sh
NSSERVER="xxx.xxx.xxx.xxx"
MYNAME=host1.example.com
MYADDR=$1
/usr/bin/nsupdate -y host1.example.com.:XXXX...XXXX== \
    1>/dev/null 2>&1 <<EOF
server ${NSSERVER}
update delete $MYNAME. A
update add ${MYNAME}. 60 A ${MYADDR}
send
EOF


The key can be generated by

dnssec-keygen -a HMAC-MD5 -b 128 -n ENTITY password

Le line Key: in Kpassword.+157+xxxxxx.private
contains a key witch can be used in place off XXXX...XXXX==

Thanks all.

Roberto
