nnrp.access - access file for on-campus NNTP sites
The file <config$_PATH_NNRPACCESS> (typically /var/news/etc/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
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
## Default is no access.
*:: -no- : -no- :!*
## FOO hosts have no password, can read anything.
## A related workstation can't access FOO newsgroups.
If the file contains passwords, it should not be world-readable.
