1
00:00:06,810 --> 00:00:07,643
- Okay.

2
00:00:07,643 --> 00:00:11,890
To examine the contents of an
sshd service or any service,

3
00:00:11,890 --> 00:00:16,350
'sudo systemctl cat' is
the best way to do that.

4
00:00:16,350 --> 00:00:20,520
That will show you the
actual configuration.

5
00:00:20,520 --> 00:00:22,200
And there we go.

6
00:00:22,200 --> 00:00:23,700
We can see the unit section,

7
00:00:23,700 --> 00:00:25,560
the service section, the install section,

8
00:00:25,560 --> 00:00:28,887
including this beautiful
'Restart=on-failure'.

9
00:00:30,090 --> 00:00:32,910
Now we need to make sure
that the SSH service

10
00:00:32,910 --> 00:00:36,210
will automatically be
started after a reboot.

11
00:00:36,210 --> 00:00:39,090
Maybe you just want to
check in the current

12
00:00:39,090 --> 00:00:42,180
status if that is already the case.

13
00:00:42,180 --> 00:00:45,030
And I'm looking for this 'loaded enabled'.

14
00:00:45,030 --> 00:00:49,200
'Enabled' means it's automatically
started after the reboot.

15
00:00:49,200 --> 00:00:50,970
'vendor preset: enabled'

16
00:00:50,970 --> 00:00:51,803
What is that?

17
00:00:51,803 --> 00:00:55,320
Well, that means that this unit by default

18
00:00:55,320 --> 00:00:58,350
after installation will
automatically be enabled.

19
00:00:58,350 --> 00:01:01,020
So, basically you don't
have to do anything to

20
00:01:01,020 --> 00:01:03,060
get that done anymore.

21
00:01:03,060 --> 00:01:04,683
It's an automatic procedure.

22
00:01:05,820 --> 00:01:09,000
Now, in case it's not
automatically started

23
00:01:09,000 --> 00:01:12,960
then you can use 'sudo
systemctl enable sshd'

24
00:01:13,890 --> 00:01:15,240
and that'll enable it.

25
00:01:15,240 --> 00:01:17,460
No action required here.

26
00:01:17,460 --> 00:01:19,560
Then we need to find
out the default target.

27
00:01:19,560 --> 00:01:24,560
So 'sudo systemctl
get-default' will do that.

28
00:01:26,340 --> 00:01:29,580
So 'graphical.target' is default target.

29
00:01:29,580 --> 00:01:32,730
And finally a list of all active units.

30
00:01:32,730 --> 00:01:36,300
Well, that will be 'list-units'.

31
00:01:36,300 --> 00:01:38,580
List units showing you all the units

32
00:01:38,580 --> 00:01:41,850
that are currently loaded
including their status,

33
00:01:41,850 --> 00:01:43,950
which is nice for a quick overview.

34
00:01:43,950 --> 00:01:48,483
As you can see a 152 in total,
that's quite impressive.
