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.
You can create a key value using four different methods:
Random 128 bit value, random 256 bit value, random 512 bit value or from pass-phrase (MD5-hash).
The key value generation functionality of TSIG Key Generator is already built into Simple DNS Plus and Simple Failover from JH Software.
This tool can adjust 3 'hidden' registry settings of Internet Explorer to control caching of DNS records, server connection timeout, and caching of server information.
It can be useful to change these settings to very low values, especially when testing web-servers with quickly changing DNS records / IP addresses. For example in DNS Round Robin or Simple Failover setups.
- DNS Cache Timeout
- Keep Alive Timeout
- Server Info Timeout
