Ubuntu Manpage: sudoreplay — replay sudo session logs

Provided by: sudo-ldap_1.8.21p2-3ubuntu1.6_amd64

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 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.

-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. 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 specified 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 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
(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_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.

-n, --non-interactive
Do not prompt for user input or attempt to resize the terminal. 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 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.

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.

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.

For more information on configuring sudo.conf(5), please refer to its manual.
