1
00:00:00,810 --> 00:00:08,850
Let us verify whether our system C20 is according to what we have discussed, so we will go into C20

2
00:00:08,850 --> 00:00:09,370
system.

3
00:00:10,200 --> 00:00:12,120
So this is c20 system.

4
00:00:12,130 --> 00:00:16,210
First we are going to check the hostname, whether it is okay or not.

5
00:00:16,500 --> 00:00:21,690
So it is saying c20.example.com then with dnsdomainname.

6
00:00:21,690 --> 00:00:26,190
command, we can check our domainname is also okay.

7
00:00:26,310 --> 00:00:27,230
example.com.

8
00:00:27,600 --> 00:00:30,210
Then we will check the settings in host files.

9
00:00:33,060 --> 00:00:39,500
So it is showing the 172.24.0.20 c20.example.com c20.

10
00:00:40,110 --> 00:00:48,000
Then we will check the sestatus, whether it is disable or not it is disabled in which file we made

11
00:00:48,000 --> 00:00:48,660
the changes.

12
00:00:49,020 --> 00:00:53,490
So let us show whether that is proper or not.

13
00:00:54,450 --> 00:01:01,320
So this is the file regarding selinux settings, by default it is showing now we have changed the

14
00:01:01,320 --> 00:01:08,100
setting to selinux disabled that is why our status is selinux disabled.

15
00:01:08,820 --> 00:01:11,370
Then we can check the iptables.

16
00:01:14,920 --> 00:01:23,660
List, it is showing that, by default now it is accepting every traffic, then we can check the.

17
00:01:27,100 --> 00:01:36,660
ip address, it is showing the IP addresses 172.24.0.20 and we can verify the packages rpm

18
00:01:36,660 --> 00:01:43,790
query elinks is there or not, your lynx is there or not.

19
00:01:45,700 --> 00:01:47,980
This is also browser, your Curl is there.

20
00:01:47,980 --> 00:01:56,140
curl git packages and your wget that mean.

21
00:01:56,330 --> 00:01:59,140
You can verify this also.

22
00:01:59,890 --> 00:02:01,510
And let me show you the file.

23
00:02:01,510 --> 00:02:15,310
Also we had we've made the changes /sysconfig/network-scripts/ifcfg-ens33

24
00:02:16,870 --> 00:02:23,880
So here the bootprotocol is static and IP addresses 172.24.0.20 and netmask

25
00:02:23,890 --> 00:02:28,870
this and we can check the adapter settings also.

26
00:02:29,440 --> 00:02:30,670
So settings.

27
00:02:32,650 --> 00:02:33,590
Oh, here it is.

28
00:02:33,900 --> 00:02:43,180
Bridge, that mean from NAT we have changed to the bridge so all the settings are according to what we

29
00:02:43,180 --> 00:02:49,090
have discussed, that means our all three systems are ready now what we have to do.

30
00:02:49,450 --> 00:02:57,310
We have to just check the connectivity between them, whether we are able to ping those systems or

31
00:02:57,310 --> 00:02:57,700
not.
