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==
