Well you can do almost everything; it's a powerful full feature server with:
DNS, DHCP, File, Print and FAX Server, iptables firewall, mail server with spam filter and antivirus scanner, and all the benefits of a powerful Slackware Server and a torrent station at the same time for simple users that want to download torrents safely and secure.
a. I like it and I find it the best Linux distro for me ;-)
b. Because for Servers you want simplicity and stability, and I didn't find anything other more stable and secure than Slackware...
To boot into Live mode any Pentium class processor 500MHz or AMD K2 and above will do, as for the RAM you will need at least 128MB (256MB recommended).
Booting in a slow computer with 128MB might output error with clamav-milter (needs to increase the time for loading), after you install it on disk there will be no such problem.
Donít forget that itís a server , put a decent machine on it.
SMS.Native.CD is NOT a LiveCD but a native installation of S*M*S like any other distro (Slackware). It uses classic Slackware's installer, and the advantage is that is having a lot of add-on packages to choose during the installation, such as kde add-on, Layer7 pathed kernel and iptables and many more.
If you are not familiar with other linux-live-scripts based Live CDs or Slax, .xzm is module format a.k.a add-on packages. xzm replace .mo extension from 5 series linux-live-scripts.
To use them just add them in your modules folder of SMS liveCD and rebuild the iso. If you installed your SMS on disk Live or Native you can use 'xzm2dir' command to install the add-on package to your system. example. " xzm2dir package.lzm / ".
It depends on what you want to do... Basic setups are already being done, so in many cases you don't have to do anything at all. On other cases for instance if you want to use HylaFAX server you need to add a modem on it. Default setup is under ttyS0 (Comm 1) and you need to run "faxaddmodem" to setup modem and phone details.
HylaFAX server needs a modem. Default setup is under ttyS0 (Serial Prot - Comm 1) if you plug an external modem it's ready, but you still need to setup your phone details... If you want to send and receive faxes then you will need two modems. If you don't want to use the server just disable it.
Superb Mini Server doesn't have X window server to be light and small... There is a light X window with KDE add-on for users that want it for Download... To install KDE just install the add-on package provided in the download area.
