This alpha build is intended for developers, integrators and curious users. Typical uses for this alpha build: final integration testing for third party developers; testing new hardware and drivers with the Linux 2.6.18 kernel; getting a sneak preview of the upcoming 4.2 release. This is alpha software, so quite a few software modules are still incomplete or not well tested. The most important known issues are: Webconfig template graphics and icons are incomplete; graphical console tool does not display on the screen properly....

Dual DHCP DNS Server is a combined DHCP/DNS server for small LANs.
Dynamic DHCP allocates/renews host addresses, while the caching DNS server first tries resolving from DHCP-allotted names, then from cache, and only then forwarding to external DNS servers.
Dual DHCP DNS Server supports an optional static DHCP mode and static IPs, automatic dynamic DNS updates from DHCP, and the ability to co-exist with other DHCP servers.
It is self-configuring and doesnt require the creation of zone files, and uses little memory and CPU.
Enhancements:
- This release fixes zone replication bugs.
