sudoreplay [-d directory] [-f filter] [-m max_wait] [-s speed_factor] ID
sudoreplay [-d directory] -l [search expression]
sudoreplay plays back or lists the session 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 be a six character sequence of digits and upper case letters, e.g. 0100A5, which is logged by sudo when a command is run with session logging enabled.
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:
Pause output; press any key to resume.
Reduce the playback speed by one half.
Double the playback speed.
sudoreplay accepts the following command line options:
Use directory to for the session logs instead of the default, /var/log/sudo-io.
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.
Enable "list mode". In this mode, sudoreplay will list available session IDs. 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:
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.
Evaluates to true if the command was run with the specified current working directory.
Evaluates to true if the command was run on or after IFri Jan 6 17:13:44 2012. See "Date and time format" for a description of supported date and time formats.
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.
Evaluates to true if the command was run as the specified runas_user. Note that sudo runs commands as user root by default.
Evaluates to true if the command was run on or prior to IFri Jan 6 17:13:44 2012. See "Date and time format" for a description of supported date and time formats.
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.
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 I, I and ! operators
as well as
')' for grouping (note that parentheses
must generally be escaped from the shell). The I operator is
optional, adjacent predicates have an implied I unless separated
by an I.
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.
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.
The -V (version) option causes sudoreplay to print its version number and exit.
The time and date may be specified multiple ways, common formats include:
24 hour time may be used in place of am/pm.
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.
ISO time format
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:
The current time and date.
Exactly one day from now.
24 hours ago.
2 hours ago.
The first second of the next Friday.
The current time but the first day of the coming week.
The current time but 14 days ago.
10:01 am, September 17, 2009.
10:01 am on the current day.
10:00 am on the current day.
00:00 am, September 17, 2009.
10:01 am, September 17, 2009.
The default I/O log directory.
Example session log info.
Example session standard input log.
Example session standard output log.
Example session standard error log.
Example session tty input file.
Example session tty output file.
Example session timing file.
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
