Pklinux-bigi is a Slackware derived distribution based on glibc 2.2 and Linux 2.4.0-test11. It can run on 386, 486, 586, and Pentium machines with only 4 MB of RAM. Builtin features include IP tunneling, firewalling, encapsulation, QOS(based on ipv4 RSVP), kernel debugging, loopback, network block device, and numerous filesystems (including ntfs and sysV). It contains Apache, proftpd, bind 9.0, syslogd, sendmail, iptables, iproute2, and gated. NAT configuration by iptables is included by default. It is a loopdisk based distribution which can be directly run from DOS, no hdd partitioning needed. This distribution is kept as minimal as possible and it can be useful in places where you want a low end computer to act as a firewall, webserver, mail server, router, or an alternative to zipslack.
Open Distributed Data Acquisition System Linux is a mini distribution of GNU/Linux intended for use on the ODDAS project. It contains a shell and some basic commands plus servers for HTTP, FTP and telnet. It also includes the capability to perform syslog over the network, and contains a very simple mail program which allows alerts to be forwarded across the network. The whole thing squeezes into about 3M of flash on an Intel [3-6]86 processor.
ZipSpeak is a talking mini-distribution of Linux for blind and visually impaired people, based on version 7.0 of the Slackware distribution and version 0.08 of the Speakup screen reader. Like ZipSlack, ZipSpeak is designed to be installed on an existing MS-DOS or Windows system, so that the user can try out a talking Linux system with a minimum of difficulty, and without assistance from someone who can see.
LostNIX is a Linux distribution based on the Slackware core. LostNIX is equipped with lostSEC and LostRES, an ncurses based security and package update utility system that updates from a public base constantly. This provides your system with a revolving security and pre-audited/selected update system. It also provides a built-in code sharing auto-update software called LostOPEN. This enables you to make updates to your system in a testing jail, and enables you to publish your modified code to a community directory for others to use on the fly with LostNIX.
