Failover Software

Simple Failover

'Simple Failover' is a new software based failover solution. The concept really is simple; it continuously monitors your servers to find out which are up and which are down, and then it dynamically updates your DNS records accordingly so that your domain name always points to a functional server.

TSIG Key Generator

This tool can generate a TSIG key value (base64) for you very easily. The key value complies with RFC2845. Secret Key Transaction Authentication for DNS (TSIG) is a secure method of authenticating clients making dynamic DNS update requests. The client application and the DNS server share a secret key value which is used to sign (HMAC-MD5) each update request. You can think of the key name as a user ID, and the key value as a password.
