.\" way too many mistakes in technical documents.

ident \- nnrpd ident resolver
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBident\fR [\fB\-p\fR \fIport\fR] [\fB\-t\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This program attempts to resolve usernames for \fBnnrpd\fR 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 \s-1NNTP\s0 connection.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-p\fR \fIport\fR" 4
.IX Item "-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 \fBgetservbyname\fR\|(3).  The
default value is the result of \f(CW\*(C`getservbyname("ident")\*(C'\fR if available,
or port 113 otherwise.
.IP "\fB\-t\fR" 4
.IX Item "-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 \f(CW\*(C`@\*(C'\fR
character, \fBident\fR truncates the response at the \f(CW\*(C`@\*(C'\fR.  This is useful
to allow the \fIdefault-domain\fR parameter in \fIreaders.conf\fR 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).
.SH "EXAMPLE"
.IX Header "EXAMPLE"
The following \fBreaders.conf\fR\|(5) fragment tells \fBnnrpd\fR to trust ident
information for hosts on a local network, but to replace the domain
returned from the ident query:
.PP
.Vb 5
\&    auth LAN {
\&        hosts: "192.168/16"
\&        res: "ident \-t"
\&        default\-domain: "internal.example.com"
\&    }
\&
\&    access LAN {
\&        users: "*@internal.example.com"
\&        newsgroups: example.*
\&    }
.Ve
.PP
Access is granted to the example.* groups for all users on the local
network whose machines respond to ident queries.
