From Knoppix Live-USB to Old-school CLI Debian Linux.

Alright. Here we go... The other day, I was referred to this neat little command-line Unix simulator called Cygwin. To put it lightly, I fell in love. I found Knoppix, and from what I can tell, it's a viable OS once I strip off the KDE desktop environment to make it 'old-school'. I'm...

nscd.conf

nscd.conf(5)							File Formats Manual						      nscd.conf(5)

NAME

       /etc/nscd.conf - name service cache daemon configuration file

DESCRIPTION

       The file /etc/nscd.conf is read from nscd(8) at startup. Each line specifies either an attribute and a value, or an attribute, service, and
       a value. Fields are separated either by SPACE or TAB characters. A `#' (number sign) indicates the beginning of a comment; following  char-
       acters, up to the end of the line, are not interpreted by nscd.

       Valid services are passwd, group, or hosts.

       logfile debug-file-name
	      Specifies name of the file to which debug info should be written.

       debug-level value
	      Sets the desired debug level.

       threads number
	      This is the number of threads that are started to wait for requests. At least five threads will always be created.

       server-user user
	      If  this option is set, nscd will run as this user and not as root.  If a separate cache for every user is used (-S parameter), this
	      option is ignored.

       enable-cache service <yes|no>
	      Enables or disables the specified service cache.

       positive-time-to-live service value
	      Sets the TTL (time-to-live) for positive entries (successful queries) in the specified cache for	service.   Value  is  in  seconds.
	      Larger values increase cache hit rates and reduce mean response times, but increase problems with cache coherence.

       negative-time-to-live service value
	      Sets  the  TTL  (time-to-live) for negative entries (unsuccessful queries) in the specified cache for service.  Value is in seconds.
	      Can result in significant performance improvements if there are several files owned by uids (user IDs) not in system databases  (for
	      example untarring the linux kernel sources as root); should be kept small to reduce cache coherency problems.

       suggested-size service value
	      This is the internal hash table size, value should remain a prime number for optimum efficiency.

       check-files service <yes|no>
	      Enables  or  disables  checking  the file belonging to the specified service for changes. The files are /etc/passwd, /etc/group, and
	      /etc/hosts.
