I've made some revisions to my change IP daemon script. I was having trouble with ZoneEdit getting out of sync because the script would miss an IP change, so I've updated it to check not whether the workstation thinks the IP is different, but rather check with ZoneEdit. I do call a small VBScript file, because I couldn't figure out how to parse the IP address from the ZoneEdit page using BASH scripting. I find that every problem is a nail. 


$ cat bat/chipd





eEdit.







ipfile=/etc/chipd.txt

logfile=/var/log/chipd.log

actual_ip_src="http://bovwimi.net/"

defined_ip_src="http://www.zoneedit.com/auth/edit.html?zone=yousuck.net"

datefmt="%n%Y-%m-%d %T"



  #Output banner

  date +"$datefmt"

  echo "Starting $0..."



  # Get the current actual IP from a website

  date +"$datefmt"

  echo "Grabbing current IP from $actual_ip_src..."

  actual_ip=$(lynx -source $actual_ip_src | grep -i "" | awk '{print $4}'

)



  # If we get a blank IP from the web, set actual to value in ipfile,

  # where we stored the IP we pulled during the last run if chipd

  if [ "$actual_ip" == "" ];

  then

    actual_ip=$(cat $ipfile)

  fi



  # pull HTML from ZoneEdit (contains IP)

  date +"$datefmt"

  echo "Grabbing defined IP from $defined_ip_src..."

  cd ~/bat

  lynx -source -auth=luser:password "$defined_ip_src" | grep "span class="

zone">anglo-hexon.net</span></a></td><td>   " > ipcrap_temp.txt

  defined_ip=$(cscript parseip.vbs ipcrap_temp.txt)



  # If we get a blank IP from ZoneEdit, set defined to actual

  if [ "$defined_ip" == "" ];

  then

    date +"$datefmt"

    echo "Retrieved a blank defined_ip, resetting value to $actual_ip..."

    defined_ip=$actual_ip

  fi



  # Determine if the IP has changed, if so, update everything

  if [ "$actual_ip" == "$defined_ip" ];

  then

    date +"$datefmt"

    echo "IP hasn't changed (old=$defined_ip, new=$actual_ip)..."

  else

    date +"$datefmt"

    echo "New IP detected (old=$defined_ip, new=$actual_ip), updating..."

    zedit >> $logfile

    sendip

 fi



 # Store the new IP

 defined_ip="$actual_ip"

 export defined_ip

 echo $defined_ip > $ipfile
