radzap - remove rogue entries from the active sessions database
radzap [-d raddb_directory] [-h] [-N
nas_ip_address] [-P nas_port] [-u user]
[-U user] [-x] server[:port] secret
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.
- -d raddb_directory
- The directory that contains the RADIUS configuration files. radzap
reads radiusd.conf to determine the location of the radutmp
- 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 insensitive).
- -U user
- Zap the entries which match the given username (case sensitive).
- Enable debugging output.
- 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
- 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
