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.
