Sound cool to you?
This script performs a very basic BIND security audit by way of dig which other tools—such as those located at the now highly commercialized dnsreport.com—do not. Namely, testing for the display of potentially exploitable version information and willingness to participate in anonymous zone transfer requests.
Cricket Liu’s vastly superior DNS Advisor does perform these checks, but using the free web-
based version involves a lot of typing, clicking and waiting, and the standalone version only runs on Windows. Plus they spam you incessantly if you give them a real email address. Boo for Liu.
Just pass nsho your domain name and enjoy the lack of ads as you take a look at all the juicy information your nameservers are actively whoring out to the world.
