RADMIN(8)

NAME
radmin - FreeRADIUS Administration tool

SYNOPSIS
radmin [-d config_directory] [-e command] [-f socket_file] [-i input_file] [-n name] [-o output_file] [-q]

DESCRIPTION
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.

WARNING
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.

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

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

-e command
    Run command and exit.

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

-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.

-o output_file
    Write output to the specified file. If not specified, stdout is used. This also sets "-q".

-q  Quiet mode.

COMMANDS
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
    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 information.

EXAMPLES

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 == 192.0.2.22))'
    A more complex condition that enables debugging output for requests containing User-Name "bob", or requests that originate from source IP address 192.0.2.22.

debug condition
    Disable debug conditionals.
