00:00:00,000 --> 00:00:05,006
(upbeat music)

2
00:00:05,006 --> 00:00:07,003
- [Instructor] Let's use some of these

3
00:00:07,003 --> 00:00:10,007
Linux kernel commands.

4
00:00:10,007 --> 00:00:14,002
All right, can you figure out how many loadable modules

5
00:00:14,002 --> 00:00:18,004
are currently dynamically loaded into your system?

6
00:00:18,004 --> 00:00:21,008
That should be way less than the number that are installed.

7
00:00:21,008 --> 00:00:25,008
Can you determine which was the first module loaded?

8
00:00:25,008 --> 00:00:30,003
What about is the msdos module loaded?

9
00:00:30,003 --> 00:00:32,008
If it's not loaded, load it.

10
00:00:32,008 --> 00:00:36,005
If you loaded it, is the use count zero?

11
00:00:36,005 --> 00:00:39,003
If you loaded it and the use count is zero,

12
00:00:39,003 --> 00:00:40,006
then remove the module.

13
00:00:40,006 --> 00:00:42,008
That should be safe.

14
00:00:42,008 --> 00:00:45,005
And then according to the module info

15
00:00:45,005 --> 00:00:48,008
for the sunrpc module,

16
00:00:48,008 --> 00:00:54,005
what are reported for the license, the version magic,

17
00:00:54,005 --> 00:00:57,003
and the number of module parameters?

18
00:00:57,003 --> 00:00:58,000
Give it a go.
