If you enter your password on the Ubuntu screen and you are likely to fall back to the password screen, your configuration file is damaged. This will be the first and fastest way to reset the config file, but as I always say, resetting without backup can hurt you as much as it can hurt your head.

On the basis of the process, simply follow these steps in order:

• CTRL + ALT + F2                 (my preference is to use F1 if you want F2)
  

Log in to the drop-down terminal screen. Next step

How to prevent a client from changing manual control eg 8.8.8.8? This question is in the previous article that is: Easy Way to Block Adult Sites with DNS in Mikrotik. Well in this article I will try to answer it and provide a solution to prevent clients to change DNS manually using Mikrotik.

Actually, it is more appropriate if we call “Forced” Client using Mikrotik DNS. Because anyone can just change the DNS settings on their PC respectively. Well, the thing we will do is to force the client to use our DNS even though the DNS on his PC has been changed eg to 8.8.8.8. How to do? Check out the following tutorial:

Introduction

This month we continue looking at Quality of Service (QoS) in Cisco devices.

This article looks at

• Traffic Shaping
• Policy Routing
• QoS Policy Propagation via BGP (QPPB)

Traffic Shaping

About Traffic Shaping

Traffic Shaping comes in two forms: Generic Traffic Shaping and Frame Relay Traffic Shaping.

Traffic Shaping allows you to control how fast packets are sent out an interface, any interface. You might want to do this to avoid congestion either locally or elsewhere in your network, for example if you have a network with different access rates or if you are restricting some traffic to a fraction of the available bandwidth. For example, if one end of the link in a Frame Relay network is 256 Kbps and the other end of the link is only 128 Kbps, sending packets at 256 Kbps at the very least causes congestion. Somewhere.

The moment you get into the hands of Mikrotik RouterOS is the default setting. Every time you boot is initialized and any supported hardware is immediately ready for use. In the default setting, all devices are prohibited. Primitive This must be done via the command line. To that can be accessed via the serial interface or directly via the console (monitor + keyboard). The command line enables complete administration RouterOS. The controls are very intuitive (not to deny his resemblance to the console of Cisco) and are equipped with a rich Help, which can be recalled at any time by typing a question mark “?”. Nevertheless, we assume that Most novice users will be more graphical interface WinBox. To use it, You must set the IP address and enable network interface (interface), through which the RouterOS connecting. For these purposes, RouterOS has a simple wizard that run after logged out of the system.

When you see an fcs error it is almost always the cabling on the radio at the other end of the link from where you see the FCS errors.

You can change cables over and over again on the side where the FCS occur and have minimal results.

It can be a bad cable from media converter to Mikrotik, bad media converter, the problem with fiber optic cable between 2 media converters, port on neighbor device and of course port on Mikrotik.
