DESCRIPTION

12     sudoreplay plays back or lists the output logs created by sudo.  When
13     replaying, sudoreplay can play the session back in real-time, or the
14     playback speed may be adjusted (faster or slower) based on the command
15     line options.
16
17     The ID should either be a six character sequence of digits and upper case
18     letters, e.g. 0100A5, or a pattern matching the iolog_file option in the
19     sudoers file.  When a command is run via sudo with log_output enabled in
20     the sudoers file, a TSID=ID string is logged via syslog or to the sudo
21     log file.  The ID may also be determined using sudoreplay's list mode.
22
23     In list mode, sudoreplay can be used to find the ID of a session based on
24     a number of criteria such as the user, tty or command run.
25
26     In replay mode, if the standard input and output are connected to a ter‐
27     minal and the -n option is not specified, sudoreplay will operate inter‐
28     actively.  In interactive mode, sudoreplay will attempt to adjust the
29     terminal size to match that of the session and write directly to the ter‐
30     minal (not all terminals support this).  Additionally, it will poll the
31     keyboard and act on the following keys:
32
33     ‘\n’ or ‘\r’  Skip to the next replay event; useful for long pauses.
34
35     ‘ ’ (space)   Pause output; press any key to resume.
36
37     ‘<’           Reduce the playback speed by one half.
38
39     ‘>’           Double the playback speed.
40
41     The session can be interrupted via control-C.  When the session has fin‐
42     ished, the terminal is restored to its original size if it was changed
43     during playback.
44
45     The options are as follows:
46
47     -d dir, --directory=dir
48                 Store session logs in dir instead of the default,
49                 /var/log/sudo-io.
50
51     -f filter, --filter=filter
52                 Select which I/O type(s) to display.  By default, sudoreplay
53                 will display the command's standard output, standard error
54                 and tty output.  The filter argument is a comma-separated
55                 list, consisting of one or more of following: stdin, stdout,
56                 stderr, ttyin, and ttyout.
57
58     -h, --help  Display a short help message to the standard output and exit.
59
60     -l, --list [search expression]
61                 Enable “list mode”.  In this mode, sudoreplay will list
62                 available sessions in a format similar to the sudo log file
63                 format, sorted by file name (or sequence number).  If a
64                 search expression is specified, it will be used to restrict
65                 the IDs that are displayed.  An expression is composed of the
66                 following predicates:
67
68                 command pattern
69                         Evaluates to true if the command run matches the
70                         POSIX extended regular expression pattern.
71
72                 cwd directory
73                         Evaluates to true if the command was run with the
74                         specified current working directory.
75
76                 fromdate date
77                         Evaluates to true if the command was run on or after
78                         date.  See Date and time format for a description of
79                         supported date and time formats.
80
81                 group runas_group
82                         Evaluates to true if the command was run with the
83                         specified runas_group.  Note that unless a
84                         runas_group was explicitly specified when sudo was
85                         run this field will be empty in the log.
86
87                 runas runas_user
88                         Evaluates to true if the command was run as the spec‐
89                         ified runas_user.  Note that sudo runs commands as
90                         user root by default.
91
92                 todate date
93                         Evaluates to true if the command was run on or prior
94                         to date.  See Date and time format for a description
95                         of supported date and time formats.
96
97                 tty tty name
98                         Evaluates to true if the command was run on the spec‐
99                         ified terminal device.  The tty name should be speci‐
100                         fied without the /dev/ prefix, e.g. tty01 instead of
101                         /dev/tty01.
102
103                 user user name
104                         Evaluates to true if the ID matches a command run by
105                         user name.
106
107                 Predicates may be abbreviated to the shortest unique string.
108
109                 Predicates may be combined using and, or and ! operators as
110                 well as ‘(’ and ‘)’ grouping (note that parentheses must gen‐
111                 erally be escaped from the shell).  The and operator is
112                 optional, adjacent predicates have an implied and unless sep‐
113                 arated by an or.
114
115     -m, --max-wait max_wait
116                 Specify an upper bound on how long to wait between key
117                 presses or output data.  By default, sudoreplay will accu‐
118                 rately reproduce the delays between key presses or program
119                 output.  However, this can be tedious when the session
120                 includes long pauses.  When the -m option is specified,
121                 sudoreplay will limit these pauses to at most max_wait sec‐
122                 onds.  The value may be specified as a floating point number,
123                 e.g. 2.5.  A max_wait of zero or less will eliminate the
124                 pauses entirely.
125
126     -n, --non-interactive
127                 Do not prompt for user input or attempt to re-size the termi‐
128                 nal.  The session is written to the standard output, not
129                 directly to the user's terminal.
130
131     -R, --no-resize
132                 Do not attempt to re-size the terminal to match the terminal
133                 size of the session.
134
135     -s, --speed speed_factor
136                 This option causes sudoreplay to adjust the number of seconds
137                 it will wait between key presses or program output.  This can
138                 be used to slow down or speed up the display.  For example, a
139                 speed_factor of 2 would make the output twice as fast whereas
140                 a speed_factor of .5 would make the output twice as slow.
141
142     -V, --version
143                 Print the sudoreplay versions version number and exit.
144
145   Date and time format
146     The time and date may be specified multiple ways, common formats include:
147
148     HH:MM:SS am MM/DD/CCYY timezone
149             24 hour time may be used in place of am/pm.
150
151     HH:MM:SS am Month, Day Year timezone
152             24 hour time may be used in place of am/pm, and month and day
153             names may be abbreviated.  Note that month and day of the week
154             names must be specified in English.
155
156     CCYY-MM-DD HH:MM:SS
157             ISO time format
158
159     DD Month CCYY HH:MM:SS
160             The month name may be abbreviated.
161
162     Either time or date may be omitted, the am/pm and timezone are optional.
163     If no date is specified, the current day is assumed; if no time is speci‐
164     fied, the first second of the specified date is used.  The less signifi‐
165     cant parts of both time and date may also be omitted, in which case zero
166     is assumed.
167
168     The following are all valid time and date specifications:
169
170     now     The current time and date.
171
172     tomorrow
173             Exactly one day from now.
174
175     yesterday
176             24 hours ago.
177
178     2 hours ago
179             2 hours ago.
180
181     next Friday
182             The first second of the Friday in the next (upcoming) week.  Not
183             to be confused with “this Friday” which would match the Friday of
184             the current week.
185
186     last week
187             The current time but 7 days ago.  This is equivalent to “a week
188             ago”.
189
190     a fortnight ago
191             The current time but 14 days ago.
192
193     10:01 am 9/17/2009
194             10:01 am, September 17, 2009.
195
196     10:01 am
197             10:01 am on the current day.
198
199     10      10:00 am on the current day.
200
201     9/17/2009
202             00:00 am, September 17, 2009.
203
204     10:01 am Sep 17, 2009
205             10:01 am, September 17, 2009.
206
207     Note that relative time specifications do not always work as expected.
208     For example, the “next” qualifier is intended to be used in conjunction
209     with a day such as “next Monday”.  When used with units of weeks, months,
210     years, etc the result will be one more than expected.  For example, “next
211     week” will result in a time exactly two weeks from now, which is probably
212     not what was intended.  This will be addressed in a future version of
213     sudoreplay.
214
215   Debugging sudoreplay
216     sudoreplay versions 1.8.4 and higher support a flexible debugging frame‐
217     work that is configured via Debug lines in the sudo.conf(5) file.
