Install and configure RDP server on Linux...

To install freerdp on Debian, Kali Linux, Linux Mint, Ubuntu and derivatives, run the command:

$ sudo apt install freerdp2-shadow-x11 winpr-utils

To install freerdp on Arch Linux and derivatives, run the command:

$ sudo pacman -S freerdp

To start the RDP server without authentication at all, use the -auth option. Warning: if authentication is disabled, anyone can connect. Only use this option for testing.

$ freerdp-shadow-cli -auth

To start RDP server with authentication:

• First calculate the hash for password

$ winpr-hash -u myusername -p mypassword

Output:
a991ae45aa987a1a48c8bdc1209ff0e7

• Next, create SAM (example: my-sam) file and add this text

dirn:::a991ae45aa987a1a48c8bdc1209ff0e7:::

• Now start RDP server

$ freerdp-shadow-cli /sam-file:my-sam /sec:nla

• Connect from Windows
