Vários ips com a mesma porta

Vários ips com a mesma porta

Estou tentando usar vários endereços IP e executar a mesma porta. Isto é para endereços IP multicraft e dedicados.

Eu tenho a configuração das interfaces de rede como:

ifcfg-eno1
ifcfg-eno1:0 
ifcfg-eno1:1
ifcfg-eno1:2
ifcfg-eno1:3

e apenas alterou os endereços IP para 192.xxx.xxx.147,148,149,150.

Quando faço ping, ele retorna ao servidor, mas quando tento usar multicraft, ele não consegue ligar à porta.

Aqui estão as interfaces (apenas o ip mudou por um)

DEVICE="eno1"
ONBOOT=yes
NETBOOT=yes
UUID="14081356-1da3-49ca-a25d-3ed9fe2fcd32"
IPV6INIT=yes
BOOTPROTO=none
TYPE=Ethernet
DNS1=127.0.0.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPADDR=192.xxx.xxx.146
PREFIX=29
GATEWAY=192.xxx.xxx.145
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

O erro:

WARN **** FAILED TO BIND TO PORT!
13.03 01:41:25 [Server] WARN The exception was: java.net.BindException: Address already in use
13.03 01:41:25 [Server] WARN Perhaps a server is already running on that port?

A permissão de várias instâncias de multicraft na mesma máquina, todas usando a mesma porta, você precisará definir um endereço específico a ser usado para cada instância. Se a instância estiver configurada para usar 0.0.0.0 , ela será vinculada a todas as interfaces e qualquer outra instância não será vinculada.

Exemplo de uma instância, um endereço:

## The daemon will listen on the following IP/port.
## 0.0.0.0 to listen on all available interfaces (all IPs). Note that
## you will have to use the "externalIp" setting below if you set this
## to 0.0.0.0 as the control panel needs to know where to connect.
ip = 192.xxx.xxx.147
port = 25465

Note que você precisará alterar o 192.xxx.xxx.147 para um endereço real.
