Una cosa que mai sabre si és bona o dolenta en linux, és la
multitud de distribucions que hi arriben ha haber. Doncs bé en Xavier
Caballé al seu blog m’ha portat a descobrir-ne una altre: LEAF (Linux Embedded
Appliance Firewall). Una micro-distribució que cap en un disquet i que
suporta un munt de funcionalitats:
Advanced routing capabilities, IPV6 compatibility, security, simplicity, and
flexibility. The basic LBU system includes DHCP, DNS caching, and SSH services,
among other things.
The core of LBU, besides the Linux kernel itself, is the Shorewall firewall
system, from Tom Eastep. Shorewall is a highly evolved application that reads
easily edited (and well commented) configuration files to control the Linux
kernel’s Netfilter packet filtering system, and can therefore provide advanced
routing functions, including stateful packet filtering.
A la web del software hi ha moltíssima informació,
documentació i d’altres del projecte. Però si com jo sou una mica
mandrosos useu el resum que n’han fet al Tom’s Hadware: Linux Embedded Appliance Firewall (Bering-uClibc).
