Lab 2, part 2: Hardware Configuration This lesson focuses on how to examine the hardware configuration which allows someone to see how much memory is there, the processing abilities and identifies the machine's manufacturer (among other things). Participants learn step by step instructions in synchronizing servers, which is necessary for trouble shooting.
Video Transcription
00:04
All right, so we're connected to our host.
00:06
We're gonna start out by having a little look at the hardware configuration.
00:11
You want to see what kind of hardware you're running on,
00:14
which have a processors. How many processors? How much memory you have
00:20
will inspect other areas of the hardware configuration a little bit later.
00:24
But for now, we'll start with these.
00:27
So we go to our configuration tab.
00:30
Notice that I had the host selected.
00:33
If I select of'em, I could go to various tabs there. But in this case, it's the host.
00:39
The tabs will change between V, EMS and hosts
00:42
because they have different
00:44
configuration features.
00:46
So to the configuration tab,
00:49
I can start off with clicking the health status link.
00:56
So it says here what type of mother board my servers has
01:00
The X 50 an extreme
01:03
shows me that I have several processors and a lot of software components installed.
01:12
I can also look at my processors
01:15
and see that this is an Intel I seven
01:19
model 9 20 at 2.677 gigahertz,
01:25
it actually has two sockets.
01:26
I'm not sure that showing one,
01:30
but I get eight logical processors
01:33
and then this. This lets me divide this
01:37
processing capability among various virtual machines that you build
01:41
within that
01:42
within that host.
01:45
It identifies the manufacturer of the model, the BIOS version and such.
01:53
Okay, so now I will start with configuring D. N s
01:57
still in our configuration tab.
02:00
This time we're going to click a link in the software section.
02:04
We're looking for Dennis and routing.
02:15
You'll notice there is the host name here.
02:17
I'm on a local domain. This host has not been joined to a domain yet.
02:23
And Dean s server method is such a static, which basically means that you're using a host file.
02:30
What we want to do is designate a name server so that this host can communicate with other
02:38
hosts on the same sub net or through gateways to other networks.
02:44
So we'll go over to the properties link
02:51
and here we can see that we have our host named Designated were on the local domain.
02:57
There's no d n, a server address specified.
03:02
So what we want to do is join
03:07
domain that's already configured.
03:09
This one is called VM wear dot local.
03:16
We also need to configure the D. N s server.
03:21
And as I showed you earlier, the
03:23
Windows 2012 server that I built
03:25
at address 0.1 10 is providing all the service is for my virtual infrastructure,
03:35
which can also do is configure an alternate Deanna server.
03:38
In this case,
03:39
um, if you wanted to use one on the Internet, you could use time dot windows dot com.
03:46
And this is useful
03:49
to configure
03:50
so that you can get access to Internet related
03:54
sites for downloading updates to update manager and other
03:58
settings like this.
04:01
Make sure you do this securely, that we'll talk about that in a different section.
04:09
You'll notice on the routing tab that my default gateway is set to
04:13
the typical standard of using Got one,
04:21
and I can go ahead and click. Okay,
04:26
now my domain is half of humor, not local.
04:29
It shows my primary and secondary Dina servers,
04:32
and I have a default gateway, which is also required by use of the VM Colonel Port.
04:40
The next thing that will do is configure network time protocol.
04:46
This is an important step, and I always advise
04:49
administrators never to skip it.
04:54
You want your all of your machines in your network to have the same time reference.
04:59
Very important. Certain applications may break if the time difference between
05:03
a client server, for instance, is too great.
05:08
Perhaps even as few as a few minutes
05:11
might make a difference to break something.
05:15
It's also important for other reasons. You want to make sure that all of your servers are synchronized the team to the same time source, so that
05:23
if you have to do any trouble shooting or, ah, forensic investigation,
05:29
you know that all of your time stamps on log events will be
05:32
more or less synchronized.
05:36
Okay, so
05:39
we'll go in under the software section again
05:42
and click on time configuration.
05:48
The system has a time that it that it got when it was built, the host.
05:53
So if the clock was correct on that motherboard, it might be correct. Here is Well,
05:59
in this case, we're not running the NTP client yet, so it shows a status of stop.
06:03
I can go over to the properties link.
06:11
You'll notice here
06:13
that I can manually set the time and date.
06:15
Maybe you don't have an NTP server.
06:18
It's not something you're planning for your infrastructure. So
06:23
this is an option
06:25
it's better to use on T p.
06:27
Of course, as I mentioned already,
06:30
in any case, we're configuring into peace, and now we have to enable the client by clicking this box.
06:36
Standard NTP port is UDP 1 23
06:40
that should be allowed
06:42
within your typical network.
06:45
Whether or not
06:46
all individual servers can use that port three year perimeter firewalls another. Another question.
06:55
But for our purposes, the the anti P server is on the network that we're on with the host
07:03
now you need to go to the options button.
07:11
Here. We have options for how the anti P service
07:14
will be run
07:16
by default. It's set to start and stop manually,
07:21
which, of course,
07:23
might be useful if you're doing testing.
07:26
Once it's configured correctly, however, you probably want to start and stop with the host.
07:31
This last option
07:34
gives you 1/3 choice for
07:38
starting the anti P service as soon as possible. When the system is booting,
07:46
I will go to the
07:47
and TP settings.
07:51
You'll see that we need to configure an anti P server,
07:56
so I click add and get my pop up
07:59
and my address for the crux 2012 servers 1 2190 to 1 68
08:05
1 68 1
08:07
turn.
08:09
I can also add a secondary
08:15
server, but in this case I don't need one.
08:22
Well, let's go ahead and do it just in case. We want to make sure we can get an Internet time source. This is the I P for
08:31
time dot windows dot com.
08:39
Because you've added new servers, we need to restart the service,
08:41
so make sure you click that box.
08:48
I won't click. Okay,
08:52
okay, again and we'll see. The service is now running,
08:54
It's synchronized. It's time,
08:58
and I can see my primary
09:01
in secondary servers.
09:07
Next task is to configure. Directory service is
09:11
so now under the software section. Again,
09:15
we'll go down to authentication service is,
09:20
and you'll notice that my authentication at this point is local.
09:24
Which means unless the account exists
09:28
in the FC password and that's the shadow file
09:31
as a local council type account
09:33
or an account you could use with an SS H server,
09:39
there are no other authentication options,
09:41
so we want to configure at our active directory.
09:45
Since that's running on the
09:46
the two top 2012 server of'em that I showed you earlier,
09:52
So we'll click on properties
09:54
by default. It's such a local authentication will set that to actor directory
10:00
and the domain name
10:01
as the EM wear got local.
10:07
Now we can click the joint domain button.
10:11
And this is where the
10:13
administrator
10:13
password for the domain controller is required.
10:33
Okay, so I've typed that in. I've been authenticated.
10:37
No, I can click. Okay,
10:39
You'll notice my director Service's is now through active directory,
10:43
and I've joined the domain.
10:50
All right, so that concludes. Lab number two.
10:52
Uh,
10:52
don't forget to do lab number three where we work with virtual machines.
