       ident - nnrpd ident resolver


       ident [-p port] [-t]


       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.


       -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).


       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: ""

           access LAN {
               users: "*"
               newsgroups: example.*

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