SUDOREPLAY(8)						       MAINTENANCE COMMANDS						     SUDOREPLAY(8)

NAME

       sudoreplay - replay sudo session logs

SYNOPSIS

       sudoreplay [-h] [-d directory] [-f filter] [-m max_wait] [-s speed_factor] ID

       sudoreplay [-h] [-d directory] -l [search expression]

DESCRIPTION

       sudoreplay plays back or lists the output logs created by sudo.	When replaying, sudoreplay can play the session back in real-time, or the
       playback speed may be adjusted (faster or slower) based on the command line options.

       The ID should either be a six character sequence of digits and upper case letters, e.g. 0100A5, or a pattern matching the iolog_file option
       in the sudoers file.  When a command is run via sudo with log_output enabled in the sudoers file, a TSID=ID string is logged via syslog or
       to the sudo log file.  The ID may also be determined using sudoreplay's list mode.

       In list mode, sudoreplay can be used to find the ID of a session based on a number of criteria such as the user, tty or command run.

       In replay mode, if the standard output has not been redirected, sudoreplay will act on the following keys:

       ' ' (space)
	       Pause output; press any key to resume.

       '<'     Reduce the playback speed by one half.

       '>'     Double the playback speed.

OPTIONS

       sudoreplay accepts the following command line options:

       -d directory
		   Use directory to for the session logs instead of the default, /var/log/sudo-io.

       -f filter   By default, sudoreplay will play back the command's standard output, standard error and tty output.	The -f option can be used
		   to select which of these to output.	The filter argument is a comma-separated list, consisting of one or more of following:
		   stdout, stderr, and ttyout.

       -h	   The -h (help) option causes sudoreplay to print a short help message to the standard output and exit.

       -l [search expression]
		   Enable "list mode".	In this mode, sudoreplay will list available sessions in a format similar to the sudo log file format,
		   sorted by file name (or sequence number).  If a search expression is specified, it will be used to restrict the IDs that are
		   displayed.  An expression is composed of the following predicates:

		   command command pattern
			   Evaluates to true if the command run matches command pattern.  On systems with POSIX regular expression support, the
			   pattern may be an extended regular expression.  On systems without POSIX regular expression support, a simple substring
			   match is performed instead.

		   cwd directory
			   Evaluates to true if the command was run with the specified current working directory.

		   fromdate date
			   Evaluates to true if the command was run on or after date.  See "Date and time format" for a description of supported
			   date and time formats.

		   group runas_group
			   Evaluates to true if the command was run with the specified runas_group.  Note that unless a runas_group was explicitly
			   specified when sudo was run this field will be empty in the log.

		   runas runas_user
			   Evaluates to true if the command was run as the specified runas_user.  Note that sudo runs commands as user root by
			   default.

		   todate date
			   Evaluates to true if the command was run on or prior to date.  See "Date and time format" for a description of
			   supported date and time formats.

		   tty tty Evaluates to true if the command was run on the specified terminal device.  The tty should be specified without the
			   /dev/ prefix, e.g.  tty01 instead of /dev/tty01.

		   user user name
			   Evaluates to true if the ID matches a command run by user name.

		   Predicates may be abbreviated to the shortest unique string (currently all predicates may be shortened to a single character).

		   Predicates may be combined using and, or and ! operators as well as '(' and ')' for grouping (note that parentheses must
		   generally be escaped from the shell).  The and operator is optional, adjacent predicates have an implied and unless separated
		   by an or.

       -m max_wait Specify an upper bound on how long to wait between key presses or output data.  By default, sudo_replay will accurately
		   reproduce the delays between key presses or program output.	However, this can be tedious when the session includes long
		   pauses.  When the -m option is specified, sudoreplay will limit these pauses to at most max_wait seconds.  The value may be
		   specified as a floating point number, .e.g. 2.5.

       -s speed_factor
		   This option causes sudoreplay to adjust the number of seconds it will wait between key presses or program output.  This can be
		   used to slow down or speed up the display.  For example, a speed_factor of 2 would make the output twice as fast whereas a
		   speed_factor of <.5> would make the output twice as slow.

       -V	   The -V (version) option causes sudoreplay to print its version number and exit.

   Date and time format
       The time and date may be specified multiple ways, common formats include:

       HH:MM:SS am MM/DD/CCYY timezone
	       24 hour time may be used in place of am/pm.

       HH:MM:SS am Month, Day Year timezone
	       24 hour time may be used in place of am/pm, and month and day names may be abbreviated.	Note that month and day of the week names
	       must be specified in English.

       CCYY-MM-DD HH:MM:SS
	       ISO time format

       DD Month CCYY HH:MM:SS
	       The month name may be abbreviated.

       Either time or date may be omitted, the am/pm and timezone are optional.  If no date is specified, the current day is assumed; if no time
       is specified, the first second of the specified date is used.  The less significant parts of both time and date may also be omitted, in
       which case zero is assumed.  For example, the following are all valid:

       The following are all valid time and date specifications:

       now     The current time and date.

       tomorrow
	       Exactly one day from now.

       yesterday
	       24 hours ago.

       2 hours ago
	       2 hours ago.

       next Friday
	       The first second of the next Friday.

       this week
	       The current time but the first day of the coming week.

       a fortnight ago
	       The current time but 14 days ago.

       10:01 am 9/17/2009
	       10:01 am, September 17, 2009.

       10:01 am
	       10:01 am on the current day.

       10      10:00 am on the current day.

       9/17/2009
	       00:00 am, September 17, 2009.
