Cloudflare Tunnel Client
Cloudflare Tunnel Client
Contains the command-line client for Cloudflare Tunnel, a tunneling daemon that proxies traffic from the Cloudflare network to your origins. This daemon sits between Cloudflare network and your origin (e.g. a webserver). Cloudflare attracts client requests and sends them to you via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible. Extensive documentation can be found in the Cloudflare Tunnel section of the Cloudflare Docs. All usages related with proxying to your origins are available under cloudflared tunnel help. You can also use cloudflared to access Tunnel origins (that are protected with cloudflared tunnel) for TCP traffic at Layer 4 (i.e., not HTTP/web socket), which is relevant for use cases such as SSH, RDP, etc. Such usages are available under cloudflared access help. -

UFTP
Encrypted UDP based FTP with multicast
UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers. -

OpenFortiVPN
Client for PPP+TLS VPN tunnel services
openfortivpn is a command-line SSL VPN client for connecting to Fortinet FortiGate gateways without relying on proprietary GUIs. It negotiates the SSL/TLS tunnel, authenticates with credentials (and commonly with two-factor methods), then brings up a secure point-to-point interface and installs routes and DNS settings. The tool aims to be minimal and dependable: a single binary with an INI-style config file, systemd compatibility, and clear runtime diagnostics. It handles details like MTU tuning, split tunneling via pushed routes, and reconnect logic to keep the session stable. Because it works with the standard tun interface, it integrates smoothly with common Linux networking stacks and pairs well with desktop frontends such as NetworkManager plugins. For admins and developers, it’s a scriptable, cross-platform-friendly alternative that makes FortiGate access reliable on servers and developer workstations alike. -

Scrcpy GUI
A simple & beautiful GUI application for scrcpy
Scrcpy was created by the team behind the popular Android emulator Genymotion, but it is not an Android emulator itself, it displays and controls Android devices connected via USB or TCP/IP, it does not require any root access. It works with GNU/Linux, Windows, and MacOS. Scrcpy works by running a server on your Android device, and the desktop application communicates using USB (or using ADB tunneling wireless). The server streams the H.264 video of the device screen. The client decodes the video frames and displays them. The client captures input (keyboard and mouse) events, sends them to the server, and the server injects them into the device. If you want to see your Android screen interact with the app or content on your desktop, record your phone screen or perform other basic tasks, then Scrcpy is a good choice. In short, Scrcpy is an excellent way to easily view your Android screen on your computer and interact with it in real time. -
