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|auto} 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
              Try to send num_requests_per_second, evenly spaced.  This option allows you to slow
              down the rate at which radclient sends requests.  When not using -n, the default is
              to send packets as quickly as possible, with no inter-packet delays.

              Due to limitations in radclient, this option does not accurately send the requested
              number of packets per second.

       -p num_requests_in_parallel
              Send num_requests_in_parallel, without waiting for a response  for  each  one.   By
              default, radclient 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.

              This option permits you to discover the maximum load accepted by a RADIUS server.

       -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-sending 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.

              The RADIUS attributes read by radclient can contain the special  attribute  Packet-
              Dst-IP-Address.  If this attribute exists, then that IP address is where the packet
              is sent, and the server specified on the command-line is ignored.

              If the RADIUS attribute list always contains the  Packet-Dst-IP-Address  attribute,
              then the server parameter can be given as -.

              The  RADIUS  attributes read by radclient can contain the special attribute Packet-
              Dst-Port.  If this attribute exists, then that UDP port  is  where  the  packet  is
              sent, and the :port specified on the command-line is ignored.

       acct | auth | status | disconnect | auto
              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.

              The RADIUS attributes read by radclient can contain the special  attribute  Packet-
              Type.   If  this  attribute  exists, then that type of packet is sent, and the type
              specified on the command-line is ignored.

              If the RADIUS attribute list always contains the Packet-Type  attribute,  then  the
              type parameter can be given as auto.

       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 "Message-Authenticator = 0x00" | radclient 192.168.1.42 status 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"
