Dhcp not updating dns linux dating site greetings

Here is my do-nsupdate script: server is the nameserver to which updates will be sent. The update lines specify the changes to be made to one or more DNS records.The show line is optional, and causes nsupdate to display the records after updating.At first glance, one would think this is impossible.It is NOT impossible, thanks to some scripting and a couple of free services.

In fact, I would be surprised if spam fighters are not already using nsupdate to update their anti-spam and anti-virus DNS blackhole lists.

So, we need a method to update our DNS entry…a SCRIPT!

While googling around for a better solution, a friend on IRC pointing me to a utility that has been around since BIND 8: nsupdate.

nsupdate is a fantastic little utility that enable quick and secure DNS zone updates.
