.TH RADZAP 1 "8 April 2005" "" "FreeRadius Daemon" .SH NAME radzap - remove rogue entries from the active sessions database .SH SYNOPSIS .B radzap .RB [ \-d .IR raddb_directory ] .RB [ \-N .IR nas_ip_address ] .RB [ \-P .IR nas_port ] .RB [ \-u .IR user ] .RB [ \-U .IR user ] \fIserver[:port] secret\fP .SH DESCRIPTION The FreeRadius server can be configured to maintain an active session database in a file called \fIradutmp\fP. Commands like \fBradwho\fP(1) use this database. Sometimes that database can get out of sync, and then it might contain rogue entries. \fBradzap\fP can clean up this database. As of FreeRADIUS 1.1.0, \fBradzap\fP is a simple shell-script wrapper around \fBradwho\fP(1) and \fBradclient\fP(1). The sessions are "zapped" by sending an Accounting-Request packet which contains the information necessary for the server to delete the session record. \fBradzap\fP sends a packet to the server, rather than writing to \fIradutmp\fP directly, because session records may also be maintained in SQL. .SH OPTIONS .IP \-d\ \fIraddb_directory\fP The directory that contains the RADIUS configuration files. \fBradzap\fP reads \fIradiusd.conf\fP to determine the location of the \fIradutmp\fP file. .IP \-N\ \fInas_ip_address\fP Zap the entries which match the given NAS IP address. .IP \-P\ \fInas_port\fP Zap the entries which match the given NAS port. .IP \-u\ \fIuser\fP Zap the entries which match the given username (case insensitive). .IP \-U\ \fIuser\fP Zap the entries which match the given username (case sensitive). .IP 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 \fI/etc/services\fP. The service name looked for is \fBradacct\fP for accounting packets, and \fBradius\fP for all other requests. If a service is not found in \fI/etc/services\fP, 1813 and 1812 are used respectively. .IP 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. .SH SEE ALSO radwho(1), radclient(1), radiusd(8), radiusd.conf(5). .SH AUTHOR Alan DeKok <aland@ox.org>
