00:00:06,630 --> 00:00:11,100
- All right, let me use
sudo visudo on Ubuntu,

2
00:00:11,100 --> 00:00:14,550
and you will notice that
Ubuntu is not using vi

3
00:00:14,550 --> 00:00:15,870
as the default editor.

4
00:00:15,870 --> 00:00:18,120
Does that matter? Not at all.

5
00:00:18,120 --> 00:00:20,370
It works in nano as well,

6
00:00:20,370 --> 00:00:24,840
and the line that we
need to edit is defaults,

7
00:00:24,840 --> 00:00:27,567
followed by timestamp_type is global,

8
00:00:32,850 --> 00:00:36,753
and timestamp,

9
00:00:40,680 --> 00:00:44,970
timeout is 240.

10
00:00:44,970 --> 00:00:45,810
That's all.

11
00:00:45,810 --> 00:00:48,120
So in nano, we use Control + X and yes,

12
00:00:48,120 --> 00:00:50,940
we wanna save the buffer, and there we go.

13
00:00:50,940 --> 00:00:51,960
That's all.

14
00:00:51,960 --> 00:00:56,960
So from this moment on, sudo
ls/root, the regular test.

15
00:00:59,370 --> 00:01:01,350
It is going to create my credentials.

16
00:01:01,350 --> 00:01:04,350
It will catch these
credentials for four hours.

17
00:01:04,350 --> 00:01:05,610
So that means I will need

18
00:01:05,610 --> 00:01:07,863
to enter my password again tomorrow.
