SUDOREPLAY(8)             BSD System Manager's Manual            SUDOREPLAY(8)

NAME
     sudoreplay -- replay sudo session logs

SYNOPSIS
     sudoreplay [-hnR] [-d dir] [-f filter] [-m num] [-s num] ID

     sudoreplay [-h] [-d dir] -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 input and output are connected to a ter-
     minal and the -n option is not specified, sudoreplay will operate inter-
     actively.  In interactive mode, sudoreplay will attempt to adjust the
     terminal size to match that of the session and write directly to the ter-
     minal (not all terminals support this).  Additionally, it will poll the
     keyboard and act on the following keys:

     `\n' or `\r'  Skip to the next replay event; useful for long pauses.

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

     `<'           Reduce the playback speed by one half.

     `>'           Double the playback speed.

     The session can be interrupted via control-C.  When the session has fin-
     ished, the terminal is restored to its original size if it was changed
     during playback.

     The options are as follows:

     -d dir, --directory=dir
                 Store session logs in dir instead of the default,
                 /var/log/sudo-io.

     -f filter, --filter=filter
                 Select which I/O type(s) to display.  By default, sudoreplay
                 will display the command's standard output, standard error
                 and tty output.  The filter argument is a comma-separated
                 list, consisting of one or more of following: stdin, stdout,
                 stderr, ttyin, and ttyout.

     -h, --help  Display a short help message to the standard output and exit.

     -l, --list [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 pattern
                         Evaluates to true if the command run matches the
                         POSIX extended regular expression pattern.

                 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 spec-
                         ified 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 name
                         Evaluates to true if the command was run on the spec-
                         ified terminal device.  The tty name should be speci-
                         fied 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.

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

     -m, --max-wait max_wait
                 Specify an upper bound on how long to wait between key
                 presses or output data.  By default, sudoreplay will accu-
                 rately 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 sec-
                 onds.  The value may be specified as a floating point number,
                 e.g. 2.5.

     -n, --non-interactive
                 Do not prompt for user input or attempt to resize the termi-
                 nal.  The session is written to the standard output, not
                 directly to the user's terminal.

     -R, --no-resize
                 Do not attempt to resize the terminal to match the terminal
                 size of the session.

     -s, --speed 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, --version
                 Print the sudoreplay versions 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 speci-
     fied, the first second of the specified date is used.  The less signifi-
     cant parts of both time and date may also be omitted, in which case zero
     is assumed.

     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 Friday in the next (upcoming) week.  Not
             to be confused with ``this Friday'' which would match the Friday
             of the current week.

     last week
             The current time but 7 days ago.  This is equivalent to ``a week
             ago''.

     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.

     10:01 am Sep 17, 2009
             10:01 am, September 17, 2009.

     Note that relative time specifications do not always work as expected.
     For example, the ``next'' qualifier is intended to be used in conjunction
     with a day such as ``next Monday''.  When used with units of weeks,
     months, years, etc the result will be one more than expected.  For exam-
     ple, ``next week'' will result in a time exactly two weeks from now,
     which is probably not what was intended.  This will be addressed in a
     future version of sudoreplay.
