.IX Title "RADIUS.CONF 5"
.TH RADIUS.CONF 5 "2008-04-06" "INN 2.4.5" "InterNetNews Documentation"
.SH "NAME"
radius.conf \- Configuration for nnrpd RADIUS authenticator
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This describes the format and attributes of the configuration file for the
nnrpd \s-1RADIUS\s0 authenticator.  See \fIradius\fR\|(1) for more information about the
authenticator program.  The default location for this file is
\&\fIradius.conf\fR in \fIpathetc\fR.
.PP
Blank lines and lines beginning with \f(CW\*(C`#\*(C'\fR are ignored, as is anything
after a \f(CW\*(C`#\*(C'\fR on a line.  All other lines should begin with a parameter
name followed by a colon and the value of that key, except that each
section of configuration for a particular server should be enclosed in:
.PP
.Vb 3
\&    server <name> {
\&        # parameters...
\&    }
.Ve
.PP
where <name> is just some convenient label for that server.
.PP
The available parameters are:
.IP "\fIradhost\fR" 4
.IX Item "radhost"
The hostname of the \s-1RADIUS\s0 server to use for authentication.  This
parameter must be set.
.IP "\fIradport\fR" 4
.IX Item "radport"
The port to query on the \s-1RADIUS\s0 server.  Defaults to 1645 if not set.
.IP "\fIlochost\fR" 4
.IX Item "lochost"
The hostname or \s-1IP\s0 address making the request.  The \s-1RADIUS\s0 server expects
an \s-1IP\s0 address; a hostname will be translated into an \s-1IP\s0 address with
\&\fIgethostbyname()\fR.  If not given, this information isn't included in the
request (not all \s-1RADIUS\s0 setups require this information).
.IP "\fIlocport\fR" 4
.IX Item "locport"
The port the client being authenticated is connecting to.  If not given,
defaults to 119.  This doesn't need to be set unless readers are
connecting to a non-standard port.
.IP "\fIsecret\fR" 4
.IX Item "secret"
The shared secret with the \s-1RADIUS\s0 server.  If your secret includes spaces,
tabs, or \f(CW\*(C`#\*(C'\fR, be sure to include it in double quotes.  This parameter
must be set.
.IP "\fIprefix\fR" 4
.IX Item "prefix"
Prepend the value of this parameter to all usernames before passing them
to the \s-1RADIUS\s0 server.  Can be used to prepend something like \f(CW\*(C`news\-\*(C'\fR to
all usernames in order to put news users into a different namespace from
other accounts served by the same server.  If not set, nothing is
prepended.
.IP "\fIsuffix\fR" 4
.IX Item "suffix"
Append the value of this parameter to all usernames before passing them to
the \s-1RADIUS\s0 server.  This is often something like \f(CW\*(C`@example.com\*(C'\fR,
depending on how your \s-1RADIUS\s0 server is set up.  If not set, nothing is
appended.
.IP "\fIignore-source\fR" 4
.IX Item "ignore-source"
Can be set to \f(CW\*(C`true\*(C'\fR or \f(CW\*(C`false\*(C'\fR.  If set to false, the \s-1RADIUS\s0
authenticator will check to ensure that the response it receives is from
the same \s-1IP\s0 address as it sent the request to (for some added security).
If set to true, it will skip this verification check (if your \s-1RADIUS\s0
server has multiple \s-1IP\s0 addresses or if other odd things are going on, it
may be perfectly normal for the response to come from a different \s-1IP\s0
address).
.SH "EXAMPLE"
.IX Header "EXAMPLE"
Here is a configuration for a news server named news.example.com,
authenticating users against radius.example.com and appending
\&\f(CW\*(C`@example.com\*(C'\fR to all client-supplied usernames before passing them to
the \s-1RADIUS\s0 server:
.PP
.Vb 6
\&    server example {
\&        radhost: radius.example.com
\&        lochost: news.example.com
\&        secret: IamARADIUSsecRET
\&        suffix: @example.com
\&    }
.Ve
.PP
The shared secret with the \s-1RADIUS\s0 server is \f(CW\*(C`IamARADIUSsecRET\*(C'\fR.
.SH "HISTORY"
.IX Header "HISTORY"
This documentation was written by Russ Allbery <rra@stanford.edu> based on
the comments in the sample radius.conf file by Yury B. Razbegin.
