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 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’ ’ (space)<’>’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-f
filter,
--filter=filtersudoreplay 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-l,
--list [search
expression]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:
sudo was run this field will be empty in the
log.sudo runs 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 ‘(’ and
‘)’ 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 max_waitsudoreplay 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-R,
--no-resize-S,
--suspend-waitsudoreplay 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_factorsudoreplay 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,
--versionsudoreplay versions version number and
exit.The time and date may be specified multiple ways, common formats include:
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
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.
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
sudo was used as part of a pipeline for a particular
command.
List sessions run by user millert:
# sudoreplay -l user millert
List sessions run by user bob with a command containing the string vi:
# sudoreplay -l user bob command vi
List sessions run by user jeff that match a regular expression:
# sudoreplay -l user jeff command '/bin/[a-z]*sh'
List sessions run by jeff or bob on the console:
# sudoreplay -l ( user jeff or user bob ) tty console
