Dynamic IP update

[garrop]

Hello,

 

From zoneedit.com:

 

-----------------------------------

From one of our customers: It's very easy to update the dynamic zoneedit entries on UNIX with either of these two command lines (if you have wget or lynx installed):

 

lynx -source -auth=username:password 'http://dynamic.zoneedit.com/auth/dynamic.html?host=www.mydomain.com'

 

wget -O - --http-user=username --http-passwd=password 'http://dynamic.zoneedit.com/auth/dynamic.html?host=www.mydomain.com'

 

PPP users should place one of the above commands (or a perl client) in the file /etc/ppp/ip-up or /etc/ppp/ppp.linkup, which are called whenever a ppp connection is made.

 

Users of dhcpcd may place these commands in the file /etc/dhcpc/dhcpcd-eth0.exe or /etc/dhcpc/dhcpcd-eth1.exe which are executed whenever a new dynamic IP address is acquired

 

-----------------------------------------------

 

I have created the sh file and locate it within the cron.hourly directory. It is working fine, but it sends requests every hour even if it is not needed. How can avoid this and send a request only after my ip is changed?

 

I have looked for the files indicated by zoneedit.com, but can not find them within Mandrake 10.1

 

Any help will be greatly appreciated.
