sudoreplayplays back or lists the output logs created by
sudo. When replaying,
sudoreplaycan 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
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 terminal and the
-n option is not specified,
sudoreplay will operate interactively. In
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 ‘
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:
sudoreplaywill 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.
sudoreplaywill list available sessions in a format similar to the
sudolog 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:
sudowas run this field will be empty in the log.
sudoruns commands as user root by default.
Predicates may be abbreviated to the shortest unique string.
Predicates may be combined using and,
or and ! operators as well as
)’ 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
sudoreplaywill accurately reproduce the delays between key presses or program output. However, this can be tedious when the session includes long pauses. When the
-moption is specified,
sudoreplaywill 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.
sudoreplaywill ignore the time interval between when the command was suspended and when it was resumed. If the
-Soption is specified,
sudoreplaywill wait instead.
sudoreplayto 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.
sudoreplayversions version number and exit.
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:
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 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
sudoreplayversions 1.8.4 and higher support a flexible debugging framework that is configured via
Debuglines in the sudo.conf(5) file.
For more information on configuring sudo.conf(5), please refer to its manual.
Note that the stdin, stdout
and stderr files will be empty unless
