NAME

       ausearch - a tool to query audit daemon logs

SYNOPSIS

       ausearch [options]

DESCRIPTION

       ausearch  is  a  tool  that  can  query the audit daemon logs based for
       events based on different search criteria.  The  ausearch  utility  can
       also  take  input  from stdin as long as the input is the raw log data.
       Each commandline option given forms an "and"  statement.  For  example,
       searching  with  -m  and  -ui  means  return  events that have both the
       requested type and match the user id given.  An  exception  is  the  -n
       option;  multiple  nodes  are allowed in a search which will return any
       matching node.

       It should also be noted that each syscall  excursion  from  user  space
       into  the  kernel  and  back  into  user space has one event ID that is
       unique. Any auditable event that is triggered during  this  trip  share
       this ID so that they may be correlated.

       Different  parts  of  the  kernel  may  add  supplemental  records. For
       example, an audit event on the  syscall  "open"  will  also  cause  the
       kernel  to  emit a PATH record with the file name. The ausearch utility
       will present all records that make up one event  together.  This  could
       mean  that  even  though  you search for a specific kind of record, the
       resulting events may contain SYSCALL records.

       Also be aware that not all record types have the requested information.
       For example, a PATH record does not have a hostname or a loginuid.

OPTIONS

       -a, --event audit-event-id
              Search for an event based on the given event ID. Messages always
              start with something like msg=audit(1116360555.329:2401771). The
              event  ID is the number after the ':'. All audit events that are
              recorded from one application's  syscall  have  the  same  audit
              event  ID.  A  second  syscall made by the same application will
              have a different event ID. This way they are unique.

       -c, --comm comm-name
              Search for an event based on the given comm name. The comm  name
              is the executable's name from the task structure.

       -e, --exit exit-code-or-errno
              Search  for  an  event  based  on the given syscall exit code or
              errno.

       -f, --file file-name
              Search for an event based on the given filename.

       -ga, --gid-all all-group-id
              Search for an event with either effective group ID or  group  ID
              matching the given group ID.

       -ge, --gid-effective effective-group-id
              Search  for  an event with the given effective group ID or group
              name.

       -gi, --gid group-id
              Search for an event with the given group ID or group name.

       -h, --help
              Help

       -hn, --host host-name
              Search for an event with the given host name. The  hostname  can
              be  either  a  hostname, fully qualified domain name, or numeric
              network address. No attempt is made to resolve numeric addresses
              to domain names or aliases.

       -i, --interpret
              Interpret  numeric  entities  into  text.  For  example,  uid is
              converted to account name. The  conversion  is  done  using  the
              current  resources of the machine where the search is being run.
              If you have  renamed  the  accounts,  or  don't  have  the  same
              accounts on your machine, you could get misleading results.

       -if, --input file-name
              Use  the given file instead of the logs. This is to aid analysis
              where the logs have been moved to another machine or  only  part
              of a log was saved.

       --input-logs
              Use  the  log  file  location  from  auditd.conf  as  input  for
              searching. This is needed if you are using ausearch from a  cron
              job.

       --just-one
              Stop  after  emitting  the  first  event that matches the search
              criteria.

       -k, --key key-string
              Search for an event based on the given key string.

       -l, --line-buffered
              Flush output on every line. Most useful when stdout is connected
              to   a   pipe  and  the  default  block  buffering  strategy  is
              undesirable. May impose a performance penalty.

       -m, --message message-type | comma-sep-message-type-list
              Search for an event matching the given  message  type.  You  may
              also  enter a comma separated list of message types. There is an
              ALL message type that doesn't  exist  in  the  actual  logs.  It
              allows  you to get all messages in the system. The list of valid
              messages types is  long.  The  program  will  display  the  list
              whenever  no  message  type  is  passed with this parameter. The
              message type can be either text or numeric. If you enter a list,
              there can be only commas and no spaces separating the list.

       -n, --node node-name
              Search  for  events  originating from node name string. Multiple
              nodes are allowed, and if any nodes match, the event is matched.

       -o, --object SE-Linux-context-string
              Search for event with tcontext (object) matching the string.

       -p, --pid process-id
              Search for an event matching the given process ID.

       -pp, --ppid parent-process-id
              Search for an event matching the given parent process ID.

       -r, --raw
              Output is completely unformatted. This is useful for  extracting
              records that can still be interpretted by audit tools.

       -sc, --syscall syscall-name-or-value
              Search  for  an event matching the given syscall. You may either
              give the numeric syscall value or the syscall name. If you  give
              the  syscall name, it will use the syscall table for the machine
              that you are using.

       -se, --context SE-Linux-context-string
              Search for event with either scontext/subject or tcontext/object
              matching the string.

       --session Login-Session-ID
              Search  for  events  matching  the  given Login Session ID. This
              process attribute is set when a user logs in  and  can  tie  any
              process to a particular user login.

       -su, --subject SE-Linux-context-string
              Search for event with scontext (subject) matching the string.

       -sv, --success success-value
              Search  for  an  event  matching  the given success value. Legal
              values are yes and no.

       -te, --end [end-date] [end-time]
              Search for events with time stamps equal to or before the  given
              end  time. The format of end time depends on your locale. If the
              date is omitted, today is assumed. If the time is  omitted,  now
              is  assumed.  Use  24  hour  clock  time rather than AM or PM to
              specify time. An example date using  the  en_US.utf8  locale  is
              09/03/2009.  An  example  of  time  is 18:00:00. The date format
              accepted is influenced by the LC_TIME environmental variab le.

              You may also  use  the  word:  now,  recent,  today,  yesterday,
              this-week, week-ago, this-month, this-year. Today means starting
              now. Recent is 10 minutes  ago.  Yesterday  is  1  second  after
              midnight  the  previous  day.  This-week means starting 1 second
              after midnight on day 0 of the week determined  by  your  locale
              (see localtime). This-month means 1 second after midnight on day
              1 of the month. This-year means the 1 second after  midnight  on
              the first day of the first month.

       -ts, --start [start-date] [start-time]
              Search  for  events with time stamps equal to or after the given
              end time. The format of end time depends on your locale. If  the
              date  is  omitted,  today  is  assumed.  If the time is omitted,
              midnight is assumed. Use 24 hour clock time rather than AM or PM
              to  specify time. An example date using the en_US.utf8 locale is
              09/03/2009. An example of time  is  18:00:00.  The  date  format
              accepted is influenced by the LC_TIME environmental variable.

              You  may  also  use  the  word:  now,  recent, today, yesterday,
              this-week, this-month, this-year.  Today  means  starting  at  1
              second  after midnight. Recent is 10 minutes ago. Yesterday is 1
              second after midnight the previous day. This-week means starting
              1  second after midnight on day 0 of the week determined by your
              locale (see localtime). This-month means 1 second after midnight
              on  day  1  of  the  month.  This-year  means the 1 second after
              midnight on the first day of the first month.

       -tm, --terminal terminal
              Search for an event matching  the  given  terminal  value.  Some
              daemons  such  as  cron  and  atd  use  the  daemon name for the
              terminal.

       -ua, --uid-all all-user-id
              Search for an event with either user ID, effective user  ID,  or
              login user ID (auid) matching the given user ID.

       -ue, --uid-effective effective-user-id
              Search for an event with the given effective user ID.

       -ui, --uid user-id
              Search for an event with the given user ID.

       -ul, --loginuid login-id
              Search  for  an  event  with  the given login user ID. All entry
              point programs that are pamified  need  to  be  configured  with
              pam_loginuid  required for the session for searching on loginuid
              (auid) to be accurate.

       -v, --version
              Print the version and exit

       -w, --word
              String based matches must match the whole word. This category of
              matches  include:  filename,  hostname,  terminal,  and SE Linux
              context.

       -x, --executable executable
              Search for an event matching the given executable name.
