RADZAP(1) FreeRadius Daemon RADZAP(1)NAMEradzap - remove rogue entries from the active sessions database
SYNOPSISradzap [-d raddb_directory] [-h] [-N nas_ip_address] [-P nas_port] [-u
user] [-U user] [-x] server[:port] secret
DESCRIPTION
The FreeRadius server can be configured to maintain an active session
database in a file called radutmp. Commands like radwho(1) use this
database. Sometimes that database can get out of sync, and then it
might contain rogue entries. radzap can clean up this database.
As of FreeRADIUS 1.1.0, radzap is a simple shell-script wrapper around
radwho(1) and radclient(1).
The sessions are "zapped" by sending an Accounting-Request packet which
contains the information necessary for the server to delete the session
record. radzap sends a packet to the server, rather than writing to
radutmp directly, because session records may also be maintained in
SQL.
OPTIONS-d raddb_directory
The directory that contains the RADIUS configuration files.
radzap reads radiusd.conf to determine the location of the
radutmp file.
-h Print usage help information.
-N nas_ip_address
Zap the entries which match the given NAS IP address.
-P nas_port
Zap the entries which match the given NAS port.
-u user
Zap the entries which match the given username (case insensi‐
tive).
-U user
Zap the entries which match the given username (case sensitive).
-x Enable debugging output.
server[:port]
The hostname or IP address of the remote server. Optionally a
UDP port can be specified. If no UDP port is specified, it is
looked up in /etc/services. The service name looked for is
radacct for accounting packets, and radius for all other
requests. If a service is not found in /etc/services, 1813 and
1812 are used respectively.
secret The shared secret for this client. It needs to be defined on
the radius server side too, for the IP address you are sending
the radius packets from.
