"hostapd_cli deauthenticate <addr>" command can be used to do this
through the control interface. In addition, there is now support for
Disconnect-Request (RFC 5176 - Dynamic Authorization Extensions to
RADIUS) in hostapd, so this can also be initiated by the RADIUS server.
For example, radclient from FreeRADIUS can be used for this:
(echo Calling-Station-Id=<STA MAC address>
echo Event-Timestamp=`date +%s`
echo Message-Authenticator=00) |
radclient -x <NAS/AP IP addr> disconnect secret
This goes bit further than just forcing reauthentication, i.e., the
station is first disconnected. If you want to trigger reauthentication
without disconnection, CoA-Request with small Session-Timeout value
could be added for such operation (hostapd does not yet support
