Upgrading my virtual host

I’m using Toshiba Portege R830 for all tasks, including my virtual lab. This is the older model with Intel Core i5-2520M CPU. Although sometimes limited and slower, this laptop has enough power for my needs.

Here’s my story how I upgraded and empowered it to be still very usable. Let’s begin! Continue reading


Compress and change the format of your virtual disk

I explained in these articles how you could either compress or convert your virtual disk. In this article, I will show you the mighty trick to use the CloneVDI tool to perform both tasks at once.

Even better, I left original screenshots with my mistake. I will highlight that wrong step I done, so you can do everything correct from the first try.

Defragmenting virtual disk

In my previous posts, I explained how to perform the disk clean-up process, wipe free space, change the virtual disk format, replace virtual disks for any VM or compress this virtual disk. In most cases, this will result in the smaller virtual disk.

Occasionally, we will perform all those procedures without a satisfactory result. In such case, we can try one more trick – to defragment VM’s hard disk. We can do that from inside VM, as VM treats it virtual disk as regular hard disk. Continue reading

Moving Mikrotik Dude to the new location

I’m using Mikrotik Dude 4.0 beta3 for Windows over the past 6-7 years. This is the latest version that could be used as the NMS server on Windows. The newer version 6.x is designed to be used as the server only on the selected Mikrotik RouterOS platforms with the Windows client.

Here’s my story how I moved the installation of Mikrotik Dude from the original location (C:\Program Files (x86)\Dude) into the new folder.

Protect your MikroTik router against Linux kernel bugs

MikroTik just announced updated information that the latest RouterOS version 6.45.1 will protect any router against multiple Linux kernel security vulnerabilities. Any earlier MikrotTik RouterOS version is vulnerable.

Oh, don’t forget. Your Linux servers are vulnerable as well, if their kernels are older and unpatched. Continue reading

Reading free disk space in Mikrotik Dude

As I already mentioned in this post, we can read a lot of information about any Windows machine. The basis is the Host Resources MIB, defined in RFC 2790. Even better, we can filter this MIB in the Dude’s SNMP Walk tool.

In this article, I will focus only on the storage subsystem and particularly the C: drive. The same principle could be used for any other drive in the system (D:-Z:), RAM or virtual memory.

Let’s begin! Continue reading
