RustDesk - remote access to another computer's desktop from anywhere in the world, will allow you to control it as if you were sitting right in front of it. This is a direct analog of such programs as TeamViewer, AnyDesk and Splashtop.

This is a powerful and flexible remote control tool that combines simplicity, security and customization.

The main advantage is the ability to deploy your own remote access server for secure and reliable remote desktop connection due to the lack of connection to third-party servers.

Main functions and purpose:

ZenMap (NMap) is a deep network or host scanner for determining the state of scanned objects (ports and corresponding services).

Additional features: OS detection, "invisible" scanning, dynamic delay calculation and packet retransmission, parallel scanning, detection of inactive hosts, scanning using false hosts, detection of the presence of packet filters, direct RPC scanning, scanning using IP fragmentation, etc.
