JaCL Linux (Just a Command Line Linux) is a live CD distribution (a Knoppix remaster) of the Linux operating system. JaCL Linux is designed to be run as a command line driven server or utility system.
Most major command line applications or server software available in a standard Linux distribution are available in JaCL Linux. Most X11 server software and applications have been intentionally removed from the distribution in order to streamline the
distribution for use as a server or utility system.
Examples of server or utility uses for JaCL include: web server, ftp server, DNS server, SMB server, rsync server, syslog server, local disk mirroring utility, remote rsync disk mirroring utility or hardware diagnostics utility.
The removal of the X server and X applications streamlines the distribution, reduces maintenance, and may reduce the risk of vulnerabilities.
Additionally other applications have been intentionally removed or omitted from the distribution, including applications which may pose a security risk if the server is user level compromised (i.e. network scanning utilities and packet sniffing tools).
The result is a full command line live CD distribution which is about half the size of a full Knoppix CD distribution.
Here are some key features of "JaCL Linux":
· an easily upgradable system
· a password protected system by default
· security warning banners (a requirement in some work environments)
· a security hardened base system
· an easy mechanism for systems administrators to automatically configure the system at bootup
· most server and utility applications included (the fact that Knoppix
