NAME
sudoreplay - replay sudo session logs
SYNOPSIS
sudoreplay [-FhnRS] [-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, a pattern matching the iolog_file option in
the sudoers file, or a path name. Path names may be relative to the
iolog_dir option in the sudoers file (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 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. Note that 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). 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.
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. 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. 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. 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(4) file.
