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)
LeoManager (master) Incoming 10020/* LeoManager console (json)
LeoManager (master) Incoming 4369/* Erlang Port Mapper
LeoManager (master) Incoming 4020/* SNMP Listen Port
LeoManager (master) Outgoing */4369 Erlang Port Mapper
LeoManager (slave)
LeoManager (slave) Incoming 10011/* LeoManager console (text)
LeoManager (slave) Incoming 10021/* LeoManager console (json)
LeoManager (slave) Incoming 4369/* Erlang Port Mapper
LeoManager (slave) Incoming 4021/* SNMP Listen Port
LeoManager (slave) Outgoing */4369 Erlang Port Mapper
LeoStorage

LeoStorage Incoming 4010/* SNMP Listen Port
LeoStorage Outgoing */4369 Erlang Port Mapper
LeoGateway

LeoGateway Incoming 4000/* SNMP Listen Port
LeoGateway Outgoing */4369 Erlang Port Mapper

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.

## Example:
##   - This forces Erlang to use only ports 9100--9105 for distributed Erlang traffic.
$ bin/leo_storage remote_console

([email protected]127.0.0.1)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
