As of May 2011, we switched to Github to make collaborative development seamless. If you want to grab the latest Netkit source code, set up a basic git install (quick instructions are provided here) and follow these instructions, inevitably preceded by a due disclaimer:
git clone git://github.com/maxonthegit/netkit-core.git git clone git://github.com/maxonthegit/netkit-uml-kernel.git git clone git://github.com/maxonthegit/netkit-uml-filesystem.git
cd netkit-core && git pull && cd .. cd netkit-uml-kernel && git pull && cd .. cd netkit-uml-filesystem && git pull && cd ..This procedure grants read-only access to the development repository. If you are interested in actively participating in the development of Netkit, please access the Developers page instead.
