The LEAF (Linux Embedded Appliance Framework) Project is a secure, feature-rich, customizable embedded Linux network appliance for use in a variety of network topologies. Although it can be used in other ways, it is primarily used as an Internet gateway, router, firewall, and wireless access point. It began as a fork from the Linux Router Project (LRP) "linux-on-a-floppy" distribution. Most users of this distribution are primarily interested in router and firewall functions, particularly as combined with the convenience of major featuress of general Linux distributions such as shells, packet filtering, SSH servers, DNS servicess, file servers, webmin and the like. LEAF is a common choice when commercial NAT routers are insufficiently flexible or secure, or are unattractively nonconforming to open source philosophy.

Characteristics

LEAF is capable of running a powerful NAT firewall with several ancillary servicess on computer hardware generally considered obsolete, such as 486 workstations with no hard disk.

LEAF is intended to work well with read-only storage media, such as write-protected floppy drives or optical discs. Distribution sizes range from a single floppy disk to several hundred megabytes.

LEAF distributions typically include software designed to be economical in executable size, such as uClibc, BusyBox, Dropbear, and Shorewall.

LEAF's origins lie in Debian Sarge, though many boot processes and daemon control mechanisms have been modified heavily.
