RADTEST(1) FreeRADIUS Daemon RADTEST(1) NAME
radtest - send packets to a RADIUS server, show reply SYNOPSIS
radtest [-d raddb_directory] [-t pap/chap/mschap] [-x ] [-4 ] [-6 ] user password radius-server nas-port-number secret [ppphint] [nasname] DESCRIPTION
radtest is a frontend to radclient(1). It generates a list of attribute/value pairs based on the command line arguments, and feeds these into radclient. It's a fast and convenient way to test a radius server. OPTIONS
-d raddb_directory The directory that contains the RADIUS dictionary files. Defaults to /etc/raddb. -t pap/chap/mschap/eap-md5 Choose the authentiction method to use. e.g. "-t pap", "-t chap", "-t mschap", or "-t eap-md5",. Defaults to "pap". Using EAP-MD5 requires that the "radeapclient" program is installed. -x Enables debugging output for the RADIUS client. -4 Use NAS-IP-Address for the NAS address (default) -6 Use NAS-IPv6-Address for the NAS address (default) user Username to send. password Password of the user. radius-server Hostname or IP address of the radius server. Optionally, you may specify a port by appending :port nas-port-number The value of the NAS-Port attribute. Is an integer between 0 and 2^31, and it really doesn't matter what you put here. 10 will do fine. secret The shared secret for this client. ppphint If you put an integer > 0 here, radtest (or actually radclient) will add the attribute Framed-Protocol = PPP to the request packet. nasname If present, this will be resolved to an IP address and added to the request packet as the NAS-IP-Address attribute. If you don't specify it, the local hostname of the system will be used. SEE ALSO

RADCLIENT(1) FreeRADIUS Daemon RADCLIENT(1) NAME
radclient - send packets to a RADIUS server, show reply SYNOPSIS
radclient [-4] [-6] [-d raddb_directory] [-c count] [-f file] [-F] [-h] [-i id] [-n num_requests_per_second] [-p num_requests_in_parallel] [-q] [-r num_retries] [-s] [-S shared_secret_file] [-t timeout] [-v] [-x] 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
-4 Use IPv4 (default) -6 Use IPv6 -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 mul- tiple 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. -F Print the file name, packet number and reply code. -h Print usage help information. -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" SEE ALSO
