什么是端口 6000?
Port 6000 is the base port for X11 (X Window System), the display server protocol used in Unix/Linux graphical environments. X11 display :0 uses port 6000, with subsequent displays using 6001, 6002, etc. Exposing X11 ports over a network without strong authentication (xhost) is a severe security risk allowing screen capture and input injection.
