1
00:00:00,440 --> 00:00:08,560
Now let us see the demo of how to verify that apache web server lab setup connectivity is there or not.

2
00:00:08,780 --> 00:00:13,100
So we will go to our c10 and c20 system.

3
00:00:13,340 --> 00:00:21,830
And we are going to run Ping command from C10 and C20, and then we are going to connect by using the browser's

4
00:00:21,830 --> 00:00:24,340
different browser from C10 and C20.

5
00:00:24,800 --> 00:00:28,180
So let us go to our first C10 system.

6
00:00:29,240 --> 00:00:37,040
So we will first run the ping command -c2 172.24.0.1.

7
00:00:38,480 --> 00:00:39,980
So ping is working.

8
00:00:40,640 --> 00:00:41,480
No issue.

9
00:00:41,900 --> 00:00:44,600
Then we will go to C20 system.

10
00:00:44,600 --> 00:00:53,000
We will check that ping connectivity is there or not -c2 that mean to send two packets to which system.

11
00:00:53,000 --> 00:00:54,310
To our master system.

12
00:00:56,330 --> 00:01:03,620
Again connectivity is there and let us go to the c10 system and check the different browsers.

13
00:01:04,250 --> 00:01:06,170
First of all, elinks browser.

14
00:01:06,470 --> 00:01:13,730
We are going to say dump http 172.24.

15
00:01:14,130 --> 00:01:15,050
0.1.

16
00:01:16,940 --> 00:01:24,770
it is saying connection refused, we can use that lynx browser also.

17
00:01:24,970 --> 00:01:27,170
This is one of the oldest browser.

18
00:01:28,120 --> 00:01:31,520
Again, it is saying that cannot connect to the remote host.

19
00:01:32,200 --> 00:01:37,610
Then what is the another browser that we have got, your curl browser is there.

20
00:01:38,770 --> 00:01:40,540
So we are going to say curl.

21
00:01:42,220 --> 00:01:50,610
It is saying that that connection refuse it is not necessary, that you have to specify that the

22
00:01:50,620 --> 00:01:57,550
dump option so you can run the browser in this way also.

23
00:01:59,860 --> 00:02:02,200
So, again, it is a saying connection refused.

24
00:02:02,230 --> 00:02:12,250
We will say, OK, with the kill, we are going to say quit, same way that lynx you can use without

25
00:02:13,750 --> 00:02:14,860
that dump option.

26
00:02:15,880 --> 00:02:23,420
So here again, it is going to say that connection refused, unable to connect.

27
00:02:24,580 --> 00:02:31,780
So we will now go to the C20 system and again run those elinks.

28
00:02:32,500 --> 00:02:33,410
--dump.

29
00:02:34,660 --> 00:02:40,370
So http://172.24.

30
00:02:40,780 --> 00:02:41,840
0.1

31
00:02:42,340 --> 00:02:43,750
So we are going to run this.

32
00:02:44,380 --> 00:02:45,670
what it is showing again.

33
00:02:45,670 --> 00:02:48,130
It is showing that connection refused.

34
00:02:48,640 --> 00:02:58,860
And then what we are going to do, we will be using that lynx browser lynx.

35
00:03:00,070 --> 00:03:05,920
It is also showing refused connection or unable to connect to the remote host.

36
00:03:06,460 --> 00:03:09,220
And then we are going to use the curl option.

37
00:03:11,840 --> 00:03:18,710
So that means in our case, ping is working, that means system, they are able to communicate, but

38
00:03:18,710 --> 00:03:29,390
our browser, they are getting the connection refused message and that is why, because we have not

39
00:03:30,470 --> 00:03:33,480
yet started the Apache Web server on master system.

40
00:03:33,920 --> 00:03:40,140
So now next few videos, we will see how to configure our Apache Web server.

41
00:03:40,400 --> 00:03:43,970
So these lab set videos are optional.

42
00:03:44,240 --> 00:03:51,080
If you know how to already have got a apache server, straightway you want to start configuring

43
00:03:51,080 --> 00:03:54,870
that, then you can skip these lab setup videos.

44
00:03:55,190 --> 00:03:56,510
So these are optional.
