       nnrp.access - access file for on-campus NNTP sites


       The  file  /etc/news/nnrp.access specifies the access control for those
       NNTP sites that  are  not  handled  by  the  main  InterNetNews  daemon
       innd(8).  The nnrpd(8) server reads it when first spawned by innd.

       Comments  begin with a number sign (‘‘#’’) and continue through the end
       of the line.  Blank lines and comments are ignored.   All  other  lines
       should consist of five fields separated by colons:

       The  first  field is a wildmat(3)-style pattern specifying the names or
       Internet address of a set of hosts.  Before a  match  is  checked,  the
       client’s  hostname  (or its Internet address if gethostbyaddr(3) fails)
       is converted to lowercase.  Each line is matched in turn, and the  last
       successful match is taken as the correct one.

       The second field is a set of letters specifying the permissions granted
       to the client.  The perms should be chosen from the following set:
              R    The client can retrieve articles
              P    The client can post articles

       The third and fourth fields specify the username and password that  the
       client  must  use  to  authenticate  themselves  before the server will
       accept any  articles.   Note  that  no  authentication  (other  then  a
       matching  entry in this file) is required for newsreading.  If they are
       empty, then no password is required.  Whitespace in these  fields  will
       result  in  the client being unable to properly authenticate themselves
       and may be used to disable access.

       The fifth field is a set of patterns identifying  the  newsgroups  that
       the  client  is allowed to access.  The patterns are interpreted in the
       same manner as the newsfeeds(5) file.   The  default,  however,  denies
       access to all groups.

       The  access  file is normally used to provide host-level access control
       for reading and posting articles.  There are times, however, when  this
       is not sufficient and user-level access control is needed.  Whenever an
       NNTP ‘‘authinfo’’ command is used, the nnrpd server re-reads this  file
       and  looks  for  a  matching  username  and  password.   If  the  local
       newsreaders are modified to send the  ‘‘authinfo’’  command,  then  all
       host  entries  can have no access and specific users can be granted the
       appropriate read and post access.

       For example:
              ##  host:perm:user:pass:groups
              ## Default is no access.
              *::  -no-  :  -no-  :!*
              ##  FOO hosts have no password, can read anything.
              * Post:::*
              ##  A related workstation can’t access FOO newsgroups.

       If the file contains passwords, it should not be world-readable.
