nnrp.access(5)


NAME

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

DESCRIPTION

   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:
          hosts:perms:username:password:patterns

   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.
          *.foo.com:Read Post:::*
          ##  A related workstation can't access FOO newsgroups.
          lenox.foo.net:RP:martha:hiatt:*,!foo.*

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