The cpuser_port_authority Script پرینت این مقاله
Overview:
The cpuser_port_authority script assigns one or more 5-digit port numbers for a user’s exclusive use. These five-digit port numbers use the range of 10000 to 65535. They exclude any ephemeral ports and passive ports.
Important:

rootuser access to use this script. - You must use
iptablesto enforce port ownership. If you usefirewalld, the system does not currently enforce port ownership.
