NAME

       ident - nnrpd ident resolver

SYNOPSIS

       ident [-p port] [-t]

DESCRIPTION

       This program attempts to resolve usernames for nnrpd by using the ident protocol to query the remote
       host.  It contacts the remote host using either IPv4 or IPv6 depending on which protocol was used for the
       incoming NNTP connection.

OPTIONS

       -p port
           If this option is given, attempt to contact identd on the specified remote port (which can be a
           numeric or symbolic specification).  Non-numeric values will be looked up using getservbyname(3).
           The default value is the result of "getservbyname("ident")" if available, or port 113 otherwise.

       -t  If this option is given, the identity returned will never have a domain part.  That is, if the remote
           server returns a result containing an "@" character, ident truncates the response at the "@".  This
           is useful to allow the default-domain parameter in reaers.conf to override the domain supplied by the
           remote host (particularly if the supplied domain part is an unqualified local machine name rather
           than a full domain name).

EXAMPLE

       The following readers.conf(5) fragment tells nnrpd to trust ident information for hosts on a local
       network, but to replace the domain returned from the ident query:

           auth LAN {
               hosts: "192.168/16"
               res: "ident -t"
               default-domain: "internal.example.com"
           }

           access LAN {
               users: "*@internal.example.com"
               newsgroups: example.*
           }

       Access is granted to the example.* groups for all users on the local network whose machines respond to
       ident queries.
