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

       The  file /var/spool/news/data/nnrp.access specifies the access control
       for those NNTP sites that are not handled by the main InterNetNews dae‐
       mon 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	match‐
       ing  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 newsread‐
       ers are modified to  send  the  ``authinfo''  command,  then  all  host
       entries can have no access and specific users can be granted the appro‐
       priate 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.
	      *.foo.com:Read Post:::*
	      ##  A related workstation can't access FOO newsgroups.

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