radmin can help, e.g.

# radmin -d /path/to/raddb
radmin> debug file debugout
radmin> show debug file
/var/log/freeradius/debugout
radmin> debug condition 'Calling-Station-Id == "aa-bb-cc-dd-ee-ff"'
(do test from client aa-bb-cc-dd-ee-ff)
radmin> debug condition
(tail -f & wait for file to finish being written to)
radmin> debug file
radmin> exit

then the debugout file should contain only debug output from when
the condition was true on the incoming request.

To get the server config, just run radiusd -X on the running
server. It will dump out the startup logging, then refuse to run
any further because there is already another radiusd listening on
the udp ports.

To use radmin you need to have enabled the control-socket virtual
server, and set "mode = rw".
