NAME

     sudoreplay — replay sudo session logs

SYNOPSIS

     sudoreplay [-FhnRS] [-d dir] [-f filter] [-m num] [-s num] ID[@offset]

     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 path name.  The ID may include an optional @offset suffix which may be used to
     start replaying at a specific time offset.  The @offset is specified as a number in seconds
     since the start of the session with an optional decimal fraction.

     Path names may be relative to the I/O log directory /var/log/sudo-io (unless overridden by
     the -d option) or fully qualified, beginning with a ‘/’ character.  When a command is run
     via sudo with log_output enabled in the sudoers file, a “TSID=ID” string is logged via
     syslog(3) 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 terminal and the -n
     option is not specified, sudoreplay will operate interactively.  In interactive mode,
     sudoreplay will attempt to adjust the terminal size to match that of the session and write
     directly to the terminal (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 finished, 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.

     -F, --follow
             Enable “follow mode”.  When replaying a session, sudoreplay will ignore end-of-file
             and keep replaying until the log is complete.  This can be used to replay a session
             that is still in progress, similar to “tail -f”.  An I/O log file is considered to
             be complete when the write bits have been cleared on the session's timing file.
             Versions of sudo prior to 1.9.1 do not clear the write bits upon completion.

     -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).  Any control characters present in the log data are formatted in octal with
             a leading ‘#’ character.  For example, a horizontal tab is displayed as ‘#011’ and
             an embedded carriage return is displayed as ‘#015’.  Space characters in the command
             name and arguments are also formatted in octal.

             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.
                     Unless a runas_group was explicitly specified when sudo was run this field
                     will be empty in the log.

             host hostname
                     Evaluates to true if the command was run on the specified hostname.

             runas runas_user
                     Evaluates to true if the command was run as the specified runas_user.  By
                     default, sudo runs commands as the root user.

             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 specified terminal device.
                     The tty name 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.

             Predicates may be combined using and, or, and ! operators as well as ‘(’ and ‘)’
             grouping (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 max_wait
             Specify an upper bound on how long to wait between key presses or output data.  By
             default, sudoreplay 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.
             A max_wait of zero or less will eliminate the pauses entirely.

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

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

     -S, --suspend-wait
             Wait while the command was suspended.  By default, sudoreplay will ignore the time
             interval between when the command was suspended and when it was resumed.  If the -S
             option is specified, sudoreplay will wait instead.

     -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.  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.

     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.

     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
     example, “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.

   Debugging sudoreplay
     sudoreplay versions 1.8.4 and higher support a flexible debugging framework that is
     configured via Debug lines in the sudo.conf(5) file.
