We can obtain the wi-fi, SSID and passwords used in our Windows operating system in two ways.

First one is GUI (graphical user interface) and the other is via Command Prompt. We will demonstrate using both methods.

The first one with GUI; I will show the operations on Windows 10, the appearance may differ in other versions.

First, click the Network icon in the lower right corner of the system or click Network and Sharing Center from the Control Panel.

What it Romon? Understanding Romon Mikrotik

Romon stands for Router Management Overlay Network which is a new feature from version RouterOS Mikrotik at 6.28. Romon this feature may be unfamiliar to you because it is only available in RouterOS and WinBox new version. Well, to find out more about what it Romon Mikrotik, let’s discuss in this article.

Understanding Romon

What it Romon? Romon (Router Management Overlay Network) is a proprietary protocol Mikrotik (protocol is only supported on Mikrotik), which can make a connection layer2 safe (secure) to the device either through connections MikroTik “Physical” (Ethernet) or Layer 2 Tunnel. In addition, Romon also has the following features:

Login to Mysql with an authorized user.

> mysql -u root -p

If more than one database exists, it can be listed with the following command.

> show databeses;

Then the database where the user is located is selected.

> use “database_name”;

The following command also lists the tables in the database.

> show tables;

You can list the fields in the table with the following command.

> describe “tables_name”;

You can use the following command to see all the data in the table.

Perform an upgrade or update to the latest version RouterOS version is to note the Mikrotik. With the upgrade version of RouterOS then Mikrotik you will get new features as well. For example for the Mikrotik RouterOS version 5.2 and have not installed the user manager it should be upgraded to the latest version (eg 5:24) first can let the user Install package manager from the download page Mikrotik.

Okay, this time Mikrotiknetworking will discuss how to upgrade the version Mikrotik RouterOS with a contrived example RB751U-2HnD of RouterOS RouterOS 5.2 to 5:24. Actually, there is a newer version that is RouterOS 6.0RC12 but since version 6 is not yet final version so the safe use version 5:24 was yes;)

It should be protected from attacks such as IP Flooding or DDOS, which in fact is the worst of the types of attacks and still has no complete solution to prevent over the world. In this case, servers on the network must hide the outside world. Hiding ICMP packets will be a starting point for this, which should already be hidden for critical servers.

This configuration can be done through firewalls above, but the method we will talk about here is to show that this process can be done in the Linux kernel module, there are many parameters like this in Linux kernel modules and these parameters are examined separately for each process and these parameters are examined individually. It must be configured. The kernel parameter for this change is the module “net.ipv4.icmp_echo_ignore_all. Now we should take a look at how to do these operations, but let’s take a look at what the default parameter of this variable is and see if it is “0”.
