psql remote database access

Im sure this has been addressed somewhere, but I wasn’t able to locate any
answers.

I have a postgres database running on a different host and I need to access
it remotely from another box.

Boxes are CentOS 6, and I opened the firewall port 5432 on the database
server host.

Also, on the database server host, I made the following entries to
/var/lib/pgsql/9.6/data/pg_hba.conf.

local all all md5

host all all 127.0.0.1/32 md5

host all all 10.42.42.16/24 md5

When I try to use psql to attach to the remote database, I get the
following error:

[root(at)host1 ~]# psql -h host2 -p 5432 -U postgres

psql: FATAL: no pg_hba.conf entry for host "10.0.0.254", user "postgres",
database "postgres", SSL off
