radmin - FreeRADIUS Administration tool
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
This tool is experimental and should not be used in production
environments. 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 its configuration.
Please exercise caution when using this command!
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".
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.
Exit from radmin.
Exit from radmin.
The other commands are implemented by the server. Type "help" at the
prompt for more information.
- 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
- debug condition
Disable debug conditionals.
