Disclaimer: This gist is a bit outdated now. The client download page now redirects to a login page that the downloads are guarded behind. You'll want to do a web search for a pulse secure deb file and install that now. Try: http://webdev.web3.technion.ac.il/docs/cis/public/ssl-vpn/ps-pulse-ubuntu-debian.deb. When I installed Pulse Secure 9.1R13, I didn't need to do anything else to get it working.

To install Pulse Secure for Ubuntu 20.04, it is a bit complicated since the support isn't great.

First, we'll want to go through the form at https://www.pulsesecure.net/trynow/client-download/. You'll get an email with download links to the latest versions of pulse secure. Download the Linux

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.
