Telstra Gateway Pro Netgear v7610 - javascript issue with Dynamic DNS service

Hi there,

 

I have enabled the Dynamic DNS Service and entered the dyndns.org credentials. When I intended to apply the change I got the pop-up error message "invalid host name" despite the hostname being perfectly valid "xxxx.dyndns.biz".

 

After checking in the javascript file "ddns.js", I found out that when validating the hostname the function check_input_value is called and this function doesn't accept a dot in the string of valid characters.

 

function check_input_value(input_str)
{
var valid="0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ%_-";
for (var i=0; i < input_str.length; i++) 
{
if (valid.indexOf(input_str.charAt(i)) < 0) 
{
return false;
}
}
}

 

In this context of DynDNS.org, the hostname will definitely contain at least one dot. The username & password is not enough to determine the DynDNS hostname for DynDNS.org

 

Please advise on how to configure DynDNS with this issue?

 

Cheers

Nico
