Free uhub software for linux

uHub is a high performance peer-2-peer hub designed for UNIX-like operating systems. The project is written in C, has a clean design and small memory footprint. It is scalable, and will work for small hubs on embedded hardware, as well as big hubs running on high preformance servers with thousands of users.
uHub uses the ADC protocol (ie. the next generation Direct Connect), and is compatible with DC++, Elise, QuickDC and other ADC clients.
Unlike other peer-2-peer networks, ADC is centralized. Clients connect to a central "hub" to communicate with other clients. It can be compared to super nodes (or ultra nodes) in other networks, except the hubs do not openly communicate between each other. The advantage to such a design is that the hubs are in control on who can access the network.
Main features:
- Easy configuration
- Advanced access control support
- Ban by network address ranges, nick name or CID
- IPv4 and IPv6 support
- Event logging
- Fast with a low memory footprint
- Support for chat only hubs (optional)
- Support for registered users only (optional)
- Runs as an unprivileged daemon (optional)
Enhancements:
- This release fixes several known crashes and cleans up the code quite a bit.
- The event handling has been refactored, a memory handling debug infrastructure is in place, and the log file format has changed slightly.
- The code base is now automatically tested for regressions.
- This release changes the license to the GPLv3.
