NAME

       radzap - remove rogue entries from the active sessions database

SYNOPSIS

       radzap [-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 main-
       tained 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 insensitive).

       -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.
