  • Also, review other sharing options such as Remote Management and disable if not required.

These steps prevent remote users from connecting via SSH or VNC, which macOS uses for remote control.

Disabling Remote Access Services on Linux

Linux systems may have services like SSH or VNC enabled that allow remote connections. To restrict remote access:

  • Identify active services with commands such as `systemctl status ssh` or `systemctl status vncserver`.
  • To disable SSH, run: `sudo systemctl disable ssh` and `sudo systemctl stop ssh`.
  • For VNC, find the specific service name (e.g., `[email protected]`) and disable it similarly.
  • Use firewall tools like `ufw` or `firewalld` to block incoming connections on ports like 22 (SSH) and 5900 (VNC).

Example firewall commands using UFW:

“`bash
sudo ufw deny 22
sudo ufw deny 5900
sudo ufw reload
“`

Ensuring these services are disabled or properly secured is critical to stopping remote access on Linux machines.
