Get a DDNS up and running with DuckDNS - Step by Step

Understanding DDNS

In summary, DDNS stands for Dynamic DNS. DDNS updates a DNS name in real-time to point to a changing IP address. This is useful for devices without a static IP. For example, companies like Google use static IPs and IP ranges, which are more expensive than ephemeral IPs and IP ranges. DDNS provides a cost-effective alternative, linking a hostname to a dynamic IP address.

How Does DDNS Work?

To use DDNS, you need an account with a DDNS provider. While some services are paid, they are still cheaper than static public IPs from ISPs. A script or service on your device updates the DDNS server with your current IP at regular intervals to maintain the link between your hostname and IP address. Luckily for us, DuckDNS is free for everybody and relays on donations to keep their services running.

Updating a HP(E) server from iLO 3 version 1.55 to version 1.94

This short document explain how to resolve the issues arising when trying to update an old (Gen7) HP(E) server to the most recent iLO 3 (HPE Integrated Lights-Out) version, which solves a great number of security and usability issues.

Issues

Can't connect to iLO with a modern browser, for lack of supported TLS protocol version
- solved by using FirefoxPortable version 31
- and in the Firefox31 portable configuration, in the about:config settings, set security.tls.version.min (the minimum acceptable version of the TLS protocol) to 0 in order to be able to negociate down to TLS 1.0 (even if iLO 3 can do 1.1). Keep in mind your browser is now (even more) vulnerable to a host of attacks, do not connect to any potentially hostile host with it.
alternatively sabotage your regular Firefox securit
