Managing Accessibility of the Node Ports

Previous pageReturn to chapter overviewNext page

Almost all node ports are closed by default for security reasons.

 

Several console command are intended to manage accessibility of the ports

when necessary:

 

kdctl allowed-ports list — to get all opened ports;

kdctl allowed-ports open <port_number> [<protocol>] — to open a port having the specified number;

kdctl allowed-ports close <port_number> [<protocol>] — to close a port having the specified number.

 

Semantics of their parameters is following:

 

port_number — port number, required;

protocol — protocol (TCP/UDP), optional, default value is TCP.
