.SH DESCRIPTION
\fBradclient\fP is a radius client program. It can send arbitrary radius
packets to a radius server, then shows the reply. It can be used to
test changes you made in the configuration of the radius server,
or it can be used to monitor if a radius server is up.
.PP
\fBradclient\fP reads radius attribute/value pairs from it standard
input, or from a file specified on the command line. It then encodes
these attribute/value pairs using the dictionary, and sends them
to the remote server.
.PP
The \fIUser-Password\fP attribute is automatically encrypted by \fIradclient\fP.

.SH OPTIONS

.IP \-c\ \fIcount\fP
Send each packet \fIcount\fP times.
\fI/etc/raddb\fP.

.IP \-d\ \fIraddb_directory\fP
The directory that contains the RADIUS dictionary files. Defaults to
\fI/etc/raddb\fP.

.IP \-f\ \fIfile\fP
File to read the attribute/value pairs from. If this is not specified,
they are read from stdin.

.IP \-i\ \fIid\fP
Use \fIid\fP as the RADIUS request Id.

.IP \-q
Go to quiet mode, and do not print out anything.

.IP \-r\ \fInum_retries\fP
Try to send each packet \fInum_retries\fP times, before giving up on
it.  The default is 10.

.IP \-s\
Print out some summaries of packets sent and received.

.IP \-S\ \fIshared_secret_file\fP
Rather than reading the shared secret from the command-line (where it
can be seen by others on the local system), read it instead from
\fIshared_secret_file\fP.

.IP \-t\ \fItimeout\fP
Wait \fItimeout\fP seconds before deciding that the NAS has not
responded to a request, and re-sending the packet.  The default
timeout is 3.

.IP \-v
Print out version information.

.IP \-x
Print out extra debugging information.

.IP server[:port]
The hostname or IP address of the remote server. Optionally a UDP port
can be specified. If no UDP port is specified, it is looked up in
\fI/etc/services\fP. The service name looked for is \fBradacct\fP for
accounting packets, and \fBradius\fP for all other requests. If a
service is not found in \fI/etc/services\fP, 1813 and 1812 are used
respectively.

.IP acct\ |\ auth |\ status |\ disconnect
Use \fBauth\fP to send an authentication packet (Access-Request),
\fBacct\fP to send an accounting packet (Accounting-Request),
\fBstatus\fP to send an status packet (Status-Server), or
\fBdisconnect\fP to send a disconnection request. Instead of these
values, you can also use a decimal code here. For example, code 12 is
also \fBStatus-Server\fP.

.IP secret
The shared secret for this client.  It needs to be defined on the
radius server side too, for the IP address you are sending the radius
packets from.

.SH EXAMPLE

A sample session that queries the remote server for \fIStatus-Server\fP
(not all servers support this.  Cistron-radiusd does since version
1.6.5):
.RS
.sp
.nf
.ne 3

$ echo "User-Name = fnord" | radclient 192.168.1.42 12 s3cr3t
Sending request to server 192.168.1.42, port 1812.
radrecv: Packet from host 192.168.1.42 code=2, id=140, length=54
    Reply-Message = "FreeRADIUS up 21 days, 02:05"
