TCP and UDP port scanning with Nmap to discover open services and identify AnyDesk

Here I am running two Nmap commands in my terminal to gather more detailed information about the target machine:

sudo nmap -sV -sC 10.48.129.195

• sudo: Runs the command with administrator (root) privileges.
• nmap: Network mapper tool used for network discovery and security auditing.
• sV: Enables version detection to identify which applications and versions are running on open ports (revealing OpenSSH 7.6p1 and an AnyDesk client on port 7070).
• sC: Runs the default NSE (Nmap Scripting Engine) scripts to gather additional information, such as SSH host keys and SSL certificates.
• 10.48.129.195: The target IP address of the lab machine.

From this, I found that port 22 is open for OpenSSH (version 7.6p1) and port 7070 is running an AnyDesk client

sudo nmap -v -sV -p 50001-50003 10.48.129.195

• sudo: Runs the command with root privileges.
• nmap: The Network Mapper tool.
• v: Increases verbosity, showing more detailed scan progress in the terminal.
• sV: Enables version detection for the specified ports.
• p 50001-50003: Limits the scan to ports 50001–50003 to check for active services such as AnyDesk.
• 10.48.129.195: The target IP address being scanned.

I scanned ports 50001 to 50003. This important range is needed to talk to the service we found earlier.
