NAME

SYNOPSIS

   semanage
   {import,export,login,user,port,interface,module,node,fcontext,boolean,permissive,dontaudit}
                   ...  positional arguments:

   import Output local customizations

   export Output local customizations

   login  Manage  login  mappings between linux users and SELinux confined
   users

   user Manage SELinux confined users (Roles and  levels  for  an  SELinux
   user)

   port Manage network port type definitions

   interface Manage network interface type definitions

   module Manage SELinux policy modules

   node Manage network node type definitions

   fcontext Manage file context mapping definitions

   boolean Manage booleans to selectively enable functionality

   permissive Manage process type enforcement mode

   dontaudit Disable/Enable dontaudit rules in policy

DESCRIPTION

   semanage  is  used  to  configure  certain  elements  of SELinux policy
   without requiring modification to or recompilation from policy sources.
   This  includes  the  mapping  from  Linux  usernames  to  SELinux  user
   identities (which controls the initial  security  context  assigned  to
   Linux  users  when  they login and bounds their authorized role set) as
   well as security context mappings for various kinds of objects, such as
   network  ports,  interfaces,  and  nodes  (hosts)  as  well as the file
   context mapping. See the EXAMPLES section below for  some  examples  of
   common  usage.   Note  that  the  semanage login command deals with the
   mapping from Linux usernames (logins) to SELinux user identities, while
   the  semanage  user  command  deals  with the mapping from SELinux user
   identities to authorized role sets.  In most  cases,  only  the  former
   mapping  needs  to  be  adjusted  by  the  administrator; the latter is
   principally defined by the base policy and  usually  does  not  require
   modification.

Opportunity


Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.



Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.



Free Books


The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.



Education


Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
