Change the Remote Desktop Connection port on Windows Server

This manual apply to Windows Server 2012, 2008 R2, 2008, 2003


The latest attacks of ransomware viruses exploit poorly protected Remote Desktop access to connect to Windows servers, then crack weak passwords and encrypt sensitive data. Hundreds of hackers continously scan the Internet to find poorly protected servers. Once you install Windows Server, it gets to the scope of hackers rather quickly - in a couple of weeks of so.


Of course, the first countermeasure to avoid accidental hacker attack is to use secure password. Never use simple or easily guessed passwords, use at least 20 character passwords with different letter casing, numbers, special symbols.


One additional countermeasure to fight automated hacker attacks is to move RDP port from default 3389 to different number, which is known only to you. This will get your server off automated port scann alorithms used by hackers and viruses. 


As we said before, default Windows servers' Remote Desktop is listening on TCP port 3389. You can change the port to different number in range 1024-65535. 

Do not use lower port number since it is reserved by system. 


IMPORTANT: Make sure that remote access to your server through the new port is authorized in your Windows firewall before executing the next steps.

How to unzip file on Ubuntu Linux

When downloading files from Internet you will often get an archive. The purpose of archive among many is to reduce download size, reduce number of files being downloaded to just one, provide basic integrity check on the subject files and sometimes provide additional security with the use of passwords. There are many archive types most commonly used of them are .zip, .rar. .7z, .tar.gz. Today we are going to speak about .zip archives. On Windows there exist GUI archivers like WinRAR or WinZip which are able to deal with most of the common archive types.

But what can you do whent you just downloaded zip file on Ubuntu Linux and have just a console? This can happen when you have installed Ubuntu Server or working from a Terminal Program.
