vi /share/CACHEDEV1_DATA/homes/dnsomatic/dnsomatic.sh

#!/bin/sh HOSTNAME="all.dnsomatic.com" USER="my_dnsomatic_user" PASS="my_dnsomatic_password" TMPFILE="/tmp/dnsomatic.oldip" DATENOW=$(date)    IP=$(/sbin/curl -s http://myip.dnsomatic.com) if [ -r "/tmp/dnsomatic.oldip" ]; then  OLDIP=`cat /tmp/dnsomatic.oldip`  if [ "$OLDIP" = "$IP" ]; then   echo "IPs match; no update"   exit 0  else   RETURN=$(/sbin/curl -s -m 60 -k -u ${USER}:${PASS} https://updates.dnsomatic.com/nic/update?hostname=${HOSTNAME}&myip=$IP&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG)   echo "Return message of DNS-O-Matic : " $RETURN   echo $RETURN | grep "good" > /dev/null 2>&1   if [ "$?" -eq "0" ]; then    echo $IP > /tmp/dnsomatic.oldip   else    echo "" > /tmp/dnsomatic.oldip   fi  fi else  touch /tmp/dnsomatic.oldip fi

Then update crontab to run it once an hour:

 vi /etc/config/crontab

1	0 */1 * * * /share/CACHEDEV1_DATA/homes/dnsomatic/dnsomatic.sh >/tmp/dnsomatic.log 2>&1

crontab /etc/config/crontab
/etc/init.d/crond.sh restart
