RADZAP(1)


NAME

  radzap - remove rogue entries from the active sessions database


SYNOPSIS

  radzap [-d raddb_directory] [-N nas_ip_address] [-P nas_port] [-u user] [-U
  user] 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 1.0.3, 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.

  -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).

  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.
