NAME

6       domain - nnrpd domain resolver
7

SYNOPSIS

9       domain domainname
10

DESCRIPTION

12       This program can be used in readers.conf to grant access based on the
13       subdomain part of the remote hostname.  In particular, it only returns
14       success if the remote hostname ends in domainname.  (A leading dot on
15       domainname is optional; even without it, the argument must match on
16       dot-separated boundaries).  The "username" returned is whatever initial
17       part of the remote hostname remains after domainname is removed.  It is
18       an error if there is no initial part (that is, if the remote hostname
19       is exactly the specified domainname).
20

EXAMPLE

22       The following readers.conf(5) fragment grants access to hosts with
23       internal domain names:
24
25           auth internal {
26               res: "domain .internal"
27               default-domain: "example.com"
28           }
29
30           access internal {
31               users: "*@example.com"
32               newsgroups: example.*
33           }
34
35       Access is granted to the example.* groups for all connections from
36       hosts that resolve to hostnames ending in ".internal"; a connection
37       from "foo.internal" would match access groups as "foo@example.com".
38

BUGS

40       It seems the code does not confirm that the matching part is actually
41       at the end of the remote hostname (e.g., "domain: example.com" would
42       match the remote host "foo.example.com.org" by ignoring the trailing
43       ".org" part).
44
45       Does this resolver actually provide any useful functionality not
46       available by using wildcards in the readers.conf(5) hosts parameter?
47       If so, the example above should reflect this functionality.
