A new “ADSL” router in my virtual lab

I keep looking for ways to improve my virtual lab and made it as realistic as possible. Although using Mikrotik routers is enough to build a large infrastructure, it’s not completely accurate with the real world experience – Mikrotik routers always work.

In the real world, we often need to connect a Mikrotik router either directly to other types of devices or even behind an exotic grandma’s home appliance. On the other hand, this is the lab and I don’t need any fancy features in such software. I want to save every megabyte of RAM or disk space on my laptop.

My search was fruitful and I found the perfect candidate – FloppyFW. This is the fully functional Linux-based router/firewall that can fit on a single 1.44” floppy disk.

“Greasy cloth” in the Internet link

A few weeks ago, I had a small project to replace one ancient Cisco router with one new MikroTik RB 2011 device. To make a long story short, I investigated the old Cisco configuration and then configured MikroTik.

After a few hours, I had the phone call. The local admin called to tell me that their Internet was terrible. There shouldn’t be any problem at all, as they are using the fiber optic link. Therefore, I connected remotely to the MikroTik device and checked its configuration.

Managing NIC Team using powershell

In this article, we will cover additional commands that can expand both our experience with PS and the NIC team in a functional way. In previous article, we covered the basic commands for the NIC teaming.

Most readers will be satisfied only with the basic commands. You may execute just two commands to create the team in a minute. Alas, sometimes we need to do more, like to replace the NIC in the team. This article can help you in such situations.

NIC Teaming – the powershell way

Whenever someone asks me to make him a new VM, I never miss an opportunity to make a joke – maybe you want a Server Core version. Some people accept the joke, but most are terrified. Then I need to relax them and tell them that this is just a joke; I know that they want the GUI.

Still, the Core version is not so scary. Neither is power shell. I will show you that in this article.

Configuring NIC Teaming remotely

I discussed, in the previous article, how you could configure the NIC Teaming feature on the local Windows Server 2012 machine with a full GUI shell. I also mentioned that you could do that remotely. Today, I will show you this method.

Although I used another Windows Server 2012 R2 machine for this demonstration, you can use Windows 8.1 (or later) desktop with a RSAT feature. The RSAT add-on is a suite of all the GUI administrative tools used on the server with the GUI.

Windows Server 2012 NIC Teaming

One of the biggest improvements in Windows Server 2012 is a feature of NIC teaming. At first glance, it is not a big deal; NIC teaming exists for years. Yes, there is a teaming feature, but not on all systems. Additionally, we can make such teaming only between NICs of the same brand and often the same model.

With Windows Server 2012 and later, we can make a team of any NICs in the system. Even more, NICs may have different speeds. Also, we can make more than one team in the same server.

Changing IP address using the command line

There is no doubt that all of you, my readers, can set a static IP address on any Windows machine. It’s so easy task. However, I’ve got a trick question – can you quickly change the IP address? What’s more, can you perform this operation on multiple computers in a short time?

Yes, you can do that manually. However, doing this manually we can make a mistake. You can become bored or simply type a wrong number. Great way to make a havoc.
