Why some processes are listening only on tcp6

[bagafoot]

Hello all, I’m trying to set up monitoring tools for postgres but agents that installed listenin only on tcp6 and monitoring tools cannot connect over tcp6. node_exporter and postgres_exporter processes.

AF_INET6 is actually both bound on IPv6 and IPv4.

Those services are listening on all IP address, IPv4 and IPv6.
