Freeradius
Table of contents
If you want to see a detailed log of what freeradius is doing, you have to run it with the -X flag.
You can either manually run it from the command line, or you can tell systemd to run it with this option by editing the file located at /etc/default/freeradius
cat /etc/default/freeradius
# Options passed to the FreeRADIUS deamon.
#
FREERADIUS_OPTIONS="-X"
# If FreeRADIUS is being used on a SysVinit system
# and FREERADIUS_OPTIONS has not been set and the
# following location exists, then it will be used
# for the config directory rather than the default.
#
# This option has no effect when systemd is in
# use, or if FREERADIUS_OPTIONS is set above.
#
FREERADIUS_CONF_LOCAL="/usr/local/etc/freeradius"
You can then follow the logs by running
journalctl -f --unit=freeradius
