gBootRoot makes the construction and development of distributions fun and simple with its Root Methods (Yard) and user-mode-linux test bed. Finish the product with a Boot Method (2-disk compression supported). Normal (non-root) users can make root filesystems and boot disks. It includes the make_debian script to create a testable user-mode-linux base Debian system, add-ons to enhance methods, and an MTD Emulator useful for running distributions made with the jffs/jffs2 filesystem.
Firewall is a set of scripts (firewall, fwup, and fwdown) that implement an ipchains firewall and various forms of network address and port translation. All you have to do is read the policy file and edit it to reflect your topology and filtering policy. It supports many different types of network topology (single host, traditional forwarding, masquerading, port forwarding, alias port forwarding and NAT), up to 10 untrusted interfaces each with their own policy, and over 50 network applications. It also supports centralised administration of multiple remote firewalls (meta-firewall).
Multicast BOOTP Java server and C/Linux client's goal is to implement the BOOTP/DHCP protocol through multicast rather than broadcast. Sun's Java networking API offers multicast socket communication objects, allowing you to create a platform independent IP interface configuration utility. Eventually, such utilities may become a fully featured multicast DHCP server. Any ideas on how to support existing BOOTP broadcast client requests are welcome. See the Multicast HOWTO at http://www.linuxdoc.org/HOWTO/Multicast- HOWTO.html.
