Firewall Rules¶
In order for a LeoFS system to operate correctly, it is necessary to set and check the firewall rules in your environment. LeoFS depends on Erlang/OTP's RPC, which uses specified ports and provides LeoFS' SNMP agent which also uses a port per a LeoFS' component node - LeoStorage, LeoGateway, and LeoManager.
| Subsystem | Direction | Ports | Description |
|---|---|---|---|
| LeoManager (master) | |||
| LeoManager (master) | Incoming | 10010/* | LeoManager console (text) |

How to Change Erlang's Port Range¶
Port range can be specified by setting Erlang's kernel variables inet_dist_listen_min and inet_dist_listen_max. If you need to change those configuration items, you need to enter the Erlang console of a target node.
1 2 3 4 5 6 7 8 | ## Example: ## - This forces Erlang to use only ports 9100--9105 for distributed Erlang traffic. $ bin/leo_storage remote_console ([email protected])1> application:set_env(kernel, inet_dist_listen_min, 9100). ([email protected])2> application:set_env(kernel, inet_dist_listen_max, 9105). ## Press [CTRL+c] to exit the Erlang console |
