       radmin - FreeRADIUS Administration tool


       radmin  [-d config_directory] [-D dictionary_directory] [-e command] [-E] [-f socket_file]
       [-h] [-i input_file] [-n name] [-q]


       FreeRADIUS Server administration tool that connects to the control  socket  of  a  running
       server, and gives a command-line interface to it.

       At this time, only a few commands are supported.  Please type "help" at the command prompt
       for detailed information about the supported commands.


       The security protections offered by this command are limited to  the  permissions  on  the
       Unix  domain  socket,  and  the  server configuration.  If someone can connect to the Unix
       domain socket, they have a substantial amount of control over the server.


       The following command-line options are accepted by the program.

       -d config directory
              Defaults to /etc/freeradius/3.0. radmin looks here  for  the  server  configuration
              files to find the "listen" section that defines the control socket filename.

       -D dictionary directory
              Set main dictionary directory. Defaults to /usr/share/freeradius.

       -e command
              Run command and exit.

       -E     Echo commands as they are being executed.

       -f socket_file
              Specify the socket filename directly.  The radiusd.conf file is not read.

       -h     Print usage help information.

       -i input_file
              Reads  input  from the specified file.  If not specified, stdin is used.  This also
              sets "-q".

       -n mname
              Read raddb/name.conf instead of raddb/radiusd.conf.

       -q     Quiet mode.


       The commands implemented by the command-line interface are almost completely controlled by
       the server.  There are a few commands interpreted locally by radmin:

              Reconnect to the server.

       quit   Exit from radmin.

       exit   Exit from radmin.

       The  other  commands  are  implemented  by the server.  Type "help" at the prompt for more


       debug file /var/log/radius/bob.log
              Set debug logs to /var/log/radius/bob.log.  There is very little checking  of  this
              filename.   Rogue  administrators may be able use this command to over-write almost
              any  file  on  the  system.   If  those  administrators  have   write   access   to
              "radius.conf", they can do the same thing without radmin, too.

       debug condition '(User-Name == "bob")'
              Enable  debugging  output  for all requests that match the condition.  Any "unlang"
              condition is valid here.  The condition is parsed  as  a  string,  so  it  must  be
              enclosed  in  single or double quotes.  Strings enclosed in double-quotes must have
              back-slashes and the quotation marks escaped inside of the string.

              Only one debug condition can be active at a time.

       debug condition '((User-Name == "bob") || (Packet-Src-IP-Address =='
              A more complex condition that enables  debugging  output  for  requests  containing
              User-Name "bob", or requests that originate from source IP address

       debug condition
              Disable debug conditionals.
