Auxiliary Desktop	(a cheap Athlon) acting as a secondary Workstation
System	-------
Distro	Slackware Linux 10.1 (as it is, full install)
Kernel	2.4.26 generic for all 486 and above
Sound	Oss SB Pci128 (es1371)
Terminal	(a cheap & old Pentium) as a Dumb Or X Terminal
System	-------
Distro	Slackware Linux 9.0 (as it is, minimal install)
Kernel	2.4.22 generic for all 486 and above
Main Server	(a cheap Celeron) providing file, ftp and web services
System	-------
Distro	Slackware Linux 9.1 (as it is, full install)
	No mouse, no monitor, no soundcard
	Just a keyboard, for the bios not to give "hairy" messages.
	I wish I had no graphics card either, but I do not know how the bios and the precompiled linux kernel would respond to that.
Platform	-------
Services	telnet, ssh, nfs, smb, web, ftp. Soon to get nis and sql working
	Main Server shares also the /home to the domain, so any user can login via any computer.
	Main Server shares also documents folders (public private and restricted) for guest MSWindows notebooks.
	When I start the nis service, this project will be completed, since user authentication will be centralized
Others	Any guest can hook [his her] Wintel or Mac laptop in my network.
	Then, network shares can be seen, and the Internet is shared by default.
	If the portable system has an X Server, remote Linux graphics applications can also run.
