radmin(8) FreeRADIUS Server Administration Tool 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 com-
mands.
WARNING
This tool is experimental and should not be used in production environ-
ments. Changes may be made at any time to the commands accepted by the
server, and/or to the resulting output.
The security protections offered by this command are pretty minimal.
If someone has permission to connect to the server, they can do almost
anything, from stopping the server, to changing it's configuration.
Please exercise caution when using this command!
OPTIONS
The following command-line options are accepted by the program.
-d config directory
Defaults to /etc/raddb. radmin looks here for the server config-
uration files to find the "listen" section that defines the con-
trol 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 com-
pletely 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 condi-
tion. 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.
