NAME
audispd.conf - the audit event dispatcher configuration file DESCRIPTION
audispd.conf is the file that controls the configuration of the audit event dispatcher. The options that are available are as follows: q_depth This is a numeric value that tells how big to make the internal queue of the audit event dispatcher. A bigger queue lets it handle a flood of events better, but could hold events that are not processed when the daemon is terminated. If you get messages in syslog about events getting dropped, increase this value. The default value is 80. overflow_action This option determines how the daemon should react to overflowing its internal queue. When this happens, it means that more events are being received than it can get rid of. This error means that it is going to lose the current event its trying to dispatch. It has the following choices: ignore, syslog, suspend, single, and halt. If set to ignore, the audisp daemon does nothing. syslog means that it will issue a warning to syslog. suspend will cause the audisp daemon to stop processing events. The daemon will still be alive. The single option will cause the audisp daemon to put the computer system in single user mode. halt option will cause the audisp daemon to shutdown the computer system. priority_boost This is a non-negative number that tells the audit event dispatcher how much of a priority boost it should take. This boost is in addition to the boost provided from the audit daemon. The default is 4. No change is 0. max_restarts This is a non-negative number that tells the audit event dispatcher how many times it can try to restart a crashed plugin. The default is 10. name_format This option controls how computer node names are inserted into the audit event stream. It has the following choices: none, hostname, fqd, numeric, and user. None means that no computer name is inserted into the audit event. hostname is the name returned by the gethostname syscall. The fqd means that it takes the hostname and resolves it with dns for a fully qualified domain name of that machine. Numeric is similar to fqd except it resolves the IP address of the machine. User is an admin defined string from the name option. The default value is none. name This is the admin defined string that identifies the machine if user is given as the name_format option. SEE ALSO

NAME
audispd - an event multiplexor SYNOPSIS
audispd DESCRIPTION
audispd is an audit event multiplexor. It has to be started by the audit daemon in order to get events. It takes audit events and distrib- utes them to child programs that want to analyze events in realtime. When the audit daemon recieves a SIGTERM or SIGHUP, it passes that signal to the dispatcher, too. The dispatcher in turn passes those signals to its child processes. The child programs install a configuration file in a plugins directory, /etc/audisp/plugins.d. Filenames are not allowed to have more than one '.' in the name or it will be treated as a backup copy and skipped. Options are given one per line with an equal sign between the key- word and its value. The available options are as follows: active The options for this are yes or no. direction The option is dictated by the plugin. In or out are the only choices. You cannot make a plugin operate in a way it wasn't designed just by changing this option.This option is to give a clue to the event dispatcher about which direction events flow. NOTE: inbound events are not supported yet. path This is the absolute path to the plugin executable. In the case of internal plugins, it would be the name of the plugin. type This tells the dispatcher how the plugin wants to be run. Choices are builtin and always. Builtin should always be given for plug- ins that are internal to the audit event dispatcher. These are af_unix and syslog. The option always should be given for most if not all plugins. The default setting is always. args This allows you to pass arguments to the child program. Generally plugins do not take arguments and have their own config file that instructs them how they should be configured. At the moment, there is a limit of 2 args. format The valid options for this are binary and string. Binary passes the data exactly as the audit event dispatcher gets it from the audit daemon. The string option tells the dispatcher to completely change the event into a string suitable for parsing with the audit parsing library. The default value is string. FILES
