CentOS 7.0 - man page for radzap (centos section 1)

RADZAP(1)					  FreeRadius Daemon					    RADZAP(1)

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. Com- mands 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 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.
