How to block domains that match a keyword?
I want to know, for internet access, if there is an easy way to filter domain names, on your Linux box, that match certain key(s) without using squid. For example, if you want to block example.com you add the following lines in your /etc/hosts file:
Code:
0.0.0.0  www.example.com
0.0.0.0  example.com
::0      www.example.com
::0      example.com

this will only block the domain example.com. However,
Code:
0.0.0.0  *ample*
0.0.0.0  *ample*
::0      *ample*
::0      *ample*

won't work. I am basically trying to block all domains which contain specific keywords which I provide. Is there a way to get this keyword-match domain filtering work without using squid? Thanks.

defaults

DEFAULTS(1)						       GNUstep System Manual						       DEFAULTS(1)

NAME

       defaults - read or modify GNUstep user defaults

SYNOPSIS

       defaults [ action ]

DESCRIPTION

       The 'defaults' command lets you to read and modify a user's defaults.

       This program replaces the old NeXTstep style dread, dwrite, and dremove programs.

       If  you have access to another user's defaults database, you may include '-u username' before any other options to use that user's database
       rather than your own.

       defaults read [ domain [ key] ]

	      read the named default from the specified domain.  If no 'key' is given - read all defaults from the  domain.   If  no  'domain'	is
	      given  - read all defaults from all domains.  A domain is either an application name, or "NSGlobalDomain", for system level defauts.
	      (Running programs can access two other domains, "NSArgumentDomain", for command line arguments,  "NSRegistrationDomain",	a  second-
	      chance domain in which "defaults for defaults" can be registered, and possibly domains for specific locales.)

       defaults readkey key

	      read the named default from all domains.

       defaults write domain key value

	      write 'value' as default 'key' in the specified domain.  'value' must be a property list in single quotes.

       defaults write domain dictionary

	      write 'dictionary' as a replacement for the specified domain.  'dictionary' must be a property list in single quotes.

       defaults write

	      reads standard input for defaults in the format produced by 'defaults read' and writes them to the database.

       defaults delete [ domain [ key] ]

	      remove the specified default(s) from the domain.	If no 'key' is given - delete the entire domain.

       defaults delete

	      read standard input for a series of lines containing pairs of domains and keys for defaults to be deleted.

       defaults domains

	      lists the domains in the database (one per line)

       defaults find word

	      searches	domain	names,	default  names, and default value strings for those equal to the specified word and lists them on standard
	      output.

       defaults plist

	      output some information about property lists

       defaults help

	      list options for the defaults command.

FILES

       ~/GNUstep/Defaults/.GNUstepDefaults
	      holds defaults for a user

BUGS

       None known.

DIAGNOSTICS

       Hopefully self-explanatory.

HISTORY

       The 'defaults' command appeared in OpenStep and combined  the  capabilities  of	the  earlier  NeXTstep	commands  'dread',  'dwrite',  and
       'dremove'.
       The GNUstep version was written in 1998.

       This manual page first appeared in gnustep-base 1.9.2 (March 2004).

       defaults was written by Richard Frith-Macdonald <rfm@gnu.org>
