It the finally worked for me, the issues I had initially were down to file paths and that I did not have dns.php. Follow the install readme from telnic.
I installed as follows.
1. I copied the .tel tools to my cgi-bin folder (as per the telnic instructions)
2. I created a folder called “Net” in my cgi-bin which I copied the net_dns files and folders.
3. I edit my .htaccess file to add: AddOutputFilter INCLUDES .html
I use shared hosting using Apache.
The software can be downloaded from the telnic. Web site. http://www2.telnic.org/tools-website-integration.html
The basic requirements are PHP 5, DNS resolver (I used the Pear Net_DNS-1.0.1. http://pear.php.net/package/Net_DNS/download)
There are many other tools available on the telnic tools page.
The .tel domain names certainly provide a good way of indexing business information, I am still learning.
A lot of .tel domains have been bought but are still not active. Check the telnic.org website
