[pgpool-general: 5745] FATAL: failed to create INET domain socket DETAIL: getaddrinfo() failed: Name or service not known

[Giancarlo Celli]

Hello everyone,
I have 2 streaming replication servers on which I've installed pgpool-II.
Postgresql in running on port 5433 and pgpool on port 5432.

Servers are connected by a cross cable to the eno2 interface, but eno1
is a public interface.

The configuration is as follows:
Server1: eno1: x.y.z.11 eno2: 192.168.0.11 Server2: eno1: x.y.z.12 eno2:
192.168.0.12 Virtual IP: x.y.z.10

(x.y.z. is just for example)
I'm sending my pgpool.conf in attachment.

pgpool does not start and in pgpool.log I can see the following output:
