NAME domain - nnrpd domain resolver

SYNOPSIS domain domainname

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

EXAMPLE The following readers.conf(5) fragment grants access to hosts with internal domain names:

auth internal { res: "domain .internal" default-domain: "" }

access internal { users: "*" newsgroups: example.* }

Access is granted to the example.* groups for all connections from hosts that resolve to hostnames ending in ".internal"; a connection from "foo.internal" would match access groups as "".

BUGS It seems the code does not confirm that the matching part is actually at the end of the remote hostname (e.g., "domain:" would match the remote host "" by ignoring the trailing ".org" part).

Does this resolver actually provide any useful functionality not avail- able by using wildcards in the readers.conf(5) hosts parameter? If so, the example above should reflect this functionality.
