SYNOPSIS

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

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 == 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 == 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.
