       hosts.nntp, hosts.nntp.nolimit - list of hosts that feed NNTP news


       The  file  /etc/news/hosts.nntp  is  read by innd(8) to get the list of
       hosts that feed the local site Usenet news  using  the  NNTP  protocol.
       The  server  reads  this  file  at  start-up  or  when  directed  to by
       ctlinnd(8).  When a host connects to the NNTP port  of  the  system  on
       which  innd  is  running,  the  server  will do a check to see if their
       Internet address is the same as one of the hosts named  in  this  file.
       If  the  host  is  not  mentioned,  then innd will spawn an nnrpd(8) to
       process the connection, with the accepted connection on standard  input
       and standard output.

       Comments  begin with a number sign (‘‘#’’) and continue through the end
       of the line.  Blank lines and comments also ignored.  All  other  lines
       should consist of two or three fields separated by a colon.

       The  first  field  should  be either an Internet address in dotted-quad
       format or an address that can be  parsed  by  gethostbyname(3).   If  a
       host’s  entry  has multiple addresses, all of them will be added to the
       access list.  The second field, which may be blank, is the password the
       foreign  host  is  required  to  use  when first connecting.  The third
       field, which may be omitted, is a list of newsgroups to which the  host
       may  send articles.  This list is parsed as a newsfeeds(5) subscription
       list; groups not in the list are ignored. Posts crossposted  in  groups
       matched by a @group.* entry are dropped.

       For example:
              ##  FOO has a password, UUNET and VIX dont.
              ##  UUNET cannot post to local groups.
              ##  Example is not part of Usenet II.
              ##  These are comment lines.

       The  first  field  may be suffixed by ‘‘/s’’ to indicate that streaming
       commands are specifically permitted to be used by this host. By default
       streaming  commands  are  available  to  all  hosts.  If  any  entry in
       hosts.nntp has a ‘‘/s’’ suffix, then only those hosts with  the  ‘‘/s’’
       suffix will be permitted to use streaming commands.

       For  example,  with  the  following  hosts.nntp  file,  only  the  host is allowed to use the streaming commands.
              ## As above, but

       The first field may be suffixed by  ‘‘/a’’  to  indicate  that  the  IP
       address  of  the  feeding  hosts allowed by this entry should always be
       included in the Path line of articles, or by ‘‘/t’’  to  indicate  that
       the  address  should  not be included, or ‘‘/a’’ followed by a pathhost
       value to indicate that the IP address should be included  if  the  most
       recent  Path  entry does not match the pathhost specified after ‘‘/a’’.
       The default is to log the address in articles whose  most  recent  Path
       entry is not the same as the hostname in the hosts.nntp entry.

       Since innd is usually started at system boot time, the local nameserver
       may not be fully operational when innd parses this file.   As  a  work-
       around,  a ctlinnd ‘‘reload’’ command can be performed after a delay of
       an hour or so.  It is also possible to provide both a host’s  name  and
       its dotted-quad address in the file.

       If  the  file contains passwords, it should not be world-readable.  The
       file /etc/news/hosts.nntp.nolimit, if it exists is  read  whenever  the
       ‘‘hosts.nntp’’ file is read.  It has the same format, although only the
       first field is used.  Any host mentioned in this file is not subject to
       the  incoming  connections limit specified by innd’s ‘‘-i’’ flag.  This
       can be used to allow local hosts or time-sensitive  peers,  to  connect
       regardless of the local conditions.
