RADCLIENT(1)                                  FreeRADIUS Daemon                                 RADCLIENT(1)



NAME
       radclient - send packets to a RADIUS server, show reply

SYNOPSIS
       radclient  [-d  raddb_directory]  [-c  count]  [-f  file]  [-i  id]  [-n num_requests_per_second] [-p
       num_requests_in_parallel] [-r num_retries] [-s] [-S shared_secret_file] [-t  timeout]  [-qvx]  server
       {acct|auth|status|disconnect} secret

DESCRIPTION
       radclient  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.

       radclient  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.

       The  User-Password and CHAP-Password attributes are automatically encrypted before the packet is sent
       to the server.


OPTIONS
       -c count
              Send each packet count times.

       -d raddb_directory
              The directory that contains the RADIUS dictionary files. Defaults to /etc/raddb.

       -f file
              File to read the attribute/value pairs from. If this is not  specified,  they  are  read  from
              stdin.   This  option can be specified multiple times, in which case packets are sent in order
              by file, and within each file, by first packet to last packet.  A blank line separates logical
              packets within a file.

       -i id  Use id as the RADIUS request Id.

       -n num_requests_per_second
              Send  num_requests_per_second,  evenly spaced over time.  By default, the requests are sent as
              fast as possible.  This option allows you to slow down  the  rate  at  which  radclient  sends
              requests.

       -p num_requests_in_parallel
              Send  num_requests_in_parallel, without waiting for a response for each one.  By default, rad-client radclient
              client sends the first request it has read, waits for the response, and once the  response  is
              received,  sends the second request in its list.  This option allows you to send many requests
              at simultaneously.  Once num_requests_in_parallel are sent, radclient waits  for  all  of  the
              responses to arrive (or for the requests to time out), before sending any more packets.

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

       -r num_retries
              Try to send each packet num_retries times, before giving up on it.  The default is 10.

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

       -S shared_secret_file
              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 shared_secret_file.

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

       -v     Print out version information.

       -x     Print out debugging information.

       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  /etc/services.  The  service  name  looked  for  is
              radacct  for  accounting packets, and radius for all other requests. If a service is not found
              in /etc/services, 1813 and 1812 are used respectively.


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


       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.


EXAMPLE
       A sample session that queries the remote server for Status-Server (not all servers support this,  but
       FreeRADIUS has configurable support for it).

              $ 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"
