HOSTS.NNTP(5)

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

DESCRIPTION
The file /usr/lib/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 hosts 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 post articles. This list is parsed as a newsfeeds(5) subscription list; groups not in the list are ignored.

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.

For example:
    ##  FOO has a password, UUNET doesn't.
    ##  UUNET cannot post to local group.s
    ##  These are comment lines.
    news.foo.com:magic
    uunet.uu.net::!foo.*

If the file contains passwords, it should not be world-readable. The file /usr/lib/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 ``-c'' flag. This can be used to allow local hosts or time-sensitive peers, to connect regardless of the local conditions.
