LEAF : Oxygen

Oxygen was designed to be used not only as a firewall, but also as a network debugging tool or a system rescue disk. It includes several powerful tools that are not found in other releases such as apkg and auto-loading of packages. Glibc is updated to version 2.1.3 and Oxygen supports loading extra packages from an IDE drive, a cdrom, a remote server, and additional data floppies. There are several preconfigured add-on floppies for general setups such as a firewall, network utilities, rescue disk, ie... and you can make your own custom add-on disk as well. Oxygen has been hardened for security, but does not offer built-in firewall capabilities with the bootdisk. You will need to add a firewall package, or use the firewall add-on disk for this capability.
