Entering the network adapter configuration.

Recently my server connection started to show flaws. As a result, there was a change in the IP address. This resulted in limited access to the network. For that reason, I started trying to solve the problem. Consequently, I wanted to go in and check the network properties. But when trying to modify the properties of the adapter, the following error message jumped.

After several minutes of research, I was able to find the solution. In the first place, click on Network and Sharing Center.

A section of the Control Panel will be immediately displayed. Please click on Change Adapter Settings.

From there it is possible to access the properties of the adapter. And as a consequence, carry out the management tasks. However, the ideal is to open this option directly using the first step mentioned.

How to change network adapter properties in Windows Server 2019/2016

To enable this control definitively, we will use the Windows Server policy editor. With this in mind, press the Win+Q combination and type in the following:

gpedit.msc

Once there, please follow the next path: Computer Configuration>Windows Settings>Security Settings>Security Options. Now, please scroll down to get the so-called policy: User Cccount Control: Admin Approval Mode for Built-In Administrator Account. Then double-click on it to edit it.

As you can see, the policy is disabled. Consequently, you only have to enable it.

Then, you just have to restart the server to set the changes. After that, you can access the properties of the adapter directly.

Ultimately we have been able to resolve the error I cannot change network adapter options in Windows Server 2019/2016. This speeds up the management of the server. Please note that it should be as smooth and stable as possible. All right, that’s it for now. See you later!

How to assign a static IP address on Windows 10 or Windows Server.

By default, operating systems assign the private IP address dynamically. That is, assigned by DHCP. The main reason for this is that everything is more automatic for connecting devices. Also, there is no need to configure anything and it saves time. On the other hand, this configuration can cause problems in some scenarios. For example, in a Server environment, a dynamic IP address is not recommended. Since it changes periodically, then it can affect the connectivity between the client computers and the server. Well, let’s look at the procedure for setting a static IP address. In the first place, it is necessary to follow the following path:

• Control Panel

• Network and Internet

• Network and Sharing Center

Once there, please click on Change adapter settings

All available network adapters will be displayed immediately. Please select the currently connected adapter and double-click on it. This will take you to the status. Finally, click on the Properties.

Modifying the IPV4 values.

Now it is necessary to configure the values of Internet Protocol Version 4. With this in mind, select the value and then click on Properties.

As you can see, the values corresponding to the IP address and the DNS server are obtained automatically.

Now it is time to modify these values according to the user’s taste. If you have trouble choosing the static IP address, I recommend using the one currently used. With this intention, from a Command Prompt run the command ipconfig. Once there, you can copy the corresponding values:

Then, just add those values to the corresponding table. As far as the DNS is concerned, please add the corresponding value to the Default gateway. Press OK to continue.

And this is all! In this simple way, we have seen how to set a static IP address in Windows 10/Server. From now on, you can play with this value within the network. Before I say goodbye, I invite you to see our post about resetting the user password in Windows Server. Bye!

Additionally, it can be used for troubleshooting to test connectivity and determine response time. However, most administrator users consider the ICMP protocol to be potentially unsafe and prefer to block these calls. For this reason, the Windows 10 firewall by default has a security policy of blocking such requests. This is easy to check, trying to ping our computer from a remote machine, we’ll see the following message:

However, it is not advisable to completely block these calls. Therefore, here I show you how to enable and disable ping in Windows 10.

Enable ping in windows 10. Command line mode.

The first thing we need to do is to open a Command Prompt as administrators. Once there, we have to create a rule for IPv4 addressing and another for IPv6. All right, to create the first rule you just have to type the following command in the console:

netsh advFirewall Firewall add rule name="OSRadar Rule PING IPv4" protocol=icmpv4:8,any dir=in action=allow 

If everything was done correctly, the CMD should look like this:

Next, we will create the rule for IPv6 addressing:

netsh advFirewall Firewall add rule name="OSRadar Rule PING IPv6" protocol=icmpv6:8,any dir=in action=allow 

We have correctly applied the rules for the ping command. We can check that it works, pinging from a remote computer:

To disable the exception for IPv4 addresses, just type the following commanding in the CMD:

netsh advFirewall Firewall add rule name="OSRadar Rule PING IPv4" protocol=icmpv4:8,any dir=in action=block 

In the case of IPv6 addressing, the command to write will be the following:

netsh advFirewall Firewall add rule name="OSRadar Rule IPv6" protocol=icmpv6:8,any dir=in action=block 

Please note that you can choose the name you want for the rules. If you want to see every rule in the system in detail, just write the following in the terminal:

 netsh advFirewall Firewall show rule name=all 

Enable ping in windows 10. Graphic mode.

It is also possible to create specific rules to enable and disable ping by entering the Windows 10 Firewall Advanced Security Configuration. With this intention, just type Firewall on the search bar:

Immediately the Firewall options will be displayed. As we did before, we have to create a rule for IPv4 and another for IPv6.

So first, select the Inbound Rules option in the left column and right-click the mouse to create a New Rule:

A rule creation wizard will start. Please select Custom in the rule type and press Next to continue.

On the next screen select All programs and press Next to continue.

In the protocol type, select ICMPv4 and then click on customize.

In the pop-up screen activate the Specific ICMP types box and navigate until you activate the Echo Request option. Press accept to apply the changes.

Next, we can define which specific IP addresses this rule will apply, on the contrary, we will allow the requests of all the addresses. Once the selection is made, press next to continue.

Now select Allow the connection and press Next to continue

In the following screen, we have to select when the new rule will be applied. Please check the 3 available options and press next to continue.

Finally, we only have to assign a name to the rule and press Finish to close the wizard.

Finally, we can see the rule created correctly. To create the exception for IPv6 addressing, we have to repeat the same process but in the protocol and ports window, we have to select ICMPv6.

To disable any of the created rules, just right-click on it and choose Disable Rule.

Conclusion

Finally, we have seen how to enable and disable ping in Windows 10. This will allow us to manage and administer our connections using this command. Finally, we have seen how to enable and disable ping in Windows 10. This will allow us to manage and administer our connections using this command. Consequently, we will be able to monitor the levels of security and data protection on our computers. This is all for now, before saying goodbye I invite you to review our tutorial on bash in Windows 10

An Internet Protocol address (IP address) is a unique identifier assigned to each device connected to a computer network that uses the Internet Protocol for communication. The IP address space is managed globally by the Internet Assigned Numbers Authority (IANA).

Their are two versions of IP address, IP Version 4 (IPv4) it uses just 32 bits and IP Version 6 (IPv6) uses 128 bits.

What is Gateway?

A gateway is the network node using the internet protocol suite that serves as the forwarding host to other networks. It allows one computer to send information to a computer in another network or the internet.

In this article you will learn that how to see server IP address and its default gateway.

How to find IP Address in Linux?

Find Private IP address:

Use one of following commands to check your machine Private IP address.

ip a

OR

ifconfig

So, In result you will get your private IP address. examples are in above images. But what if you want want to see your Public IP address

Find Public IP Address:

So, If you want want to see your Public IP address use following command.

curl ifconfig.me

How to Find Gateway in Linux?

Above you have read about Gateway address, now we will discuss that how we can see our server’s gateway.
to do so, simple run one of following commands and you will get result on your screen.

IP means “Internet Protocol“. An IP address is a number (or set of numbers) that logically and hierarchically identifies a network interface (communication/connection element) of a device (computer, tablet, laptop, smartphone) that uses the IP protocol. Every web page you visit, any computer you work from or even mobile phones and tablets, has one of these addresses when you access the internet.

According to the form and scope of IP addresses, they can be classified into Public and private; static and dynamic; Type A, B or C. Despite all of them, I will focus on dynamic and static IP.

Dynamic IP Address and Static IP Address

In short, a dynamic IP address is one that is obtained via a DHCP server. Among its main advantages are:

• Reduces the amount of assigned IP inactive.
• It provides more security because your IP can change constantly.
• IP addresses are assigned by a server.

Otherwise, static IP addresses are assigned manually by a user and will not change until the user assigns another. Nonetheless, a router can also assign this type of address through the device’s MAC address. Its main advantage is that it is easier to deploy network services. However, it is a slightly less secure method as the IP address will never change.

How to do it in CentOS 7

First, you must know what address and what the network interface is called. To do this, open a terminal and run as root user:

:~# yum install net-tools

Then, verify the name of the network interface:

:~# ip addr show

In this case, the interface name is enp0s3. In this section, you can also see the IP address of the computer.

Now you need to edit the interface configuration file.

:~# nano /etc/sysconfig/network-scripts/ifcfg-enp0s3

This is the contents of the file in my case.

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=195e564e-ecc4-477f-89ae-7158db8562fe
DEVICE=enp0s3
ONBOOT=yes
ZONE=public

Of all this, you only have to modify BOOTPROTO to static and add the following:

IPADDR=YOUR_IP
PREFIX=24
GATEWAY=YOUR_GATEWAY
DNS1=DNS_IP
DNS2=DNS_IP

These are the parameters that you must place in your case that require. For example, the IP can be the one you want, and the gateway depends on your network. DNS values are optional.

Finally, restart the network service.

:~# systemctl restart network

Then, verify the IP address.

:~# ip addr show

And that’s it.

As you could see, it’s easy to make the change to the static IP address in CentOS 7. Remember that the configuration parameters are changeable and you must have them for your connection to be correct.
