I started an amazon ec2 instance, and installed postgresql 9.1 over it. I then went to the
Security Group: quicklaunch-1(there was one more
default` which i did not change) and opened the 5432 TCP Port, the table looks like this:
(Service) Source Action
22 0.0.0.0/0 Delete
5432 0.0.0.0/32 Delete
5433 0.0.0.0/32 Delete
6432 0.0.0.0/32 Delete
I have created a database and user .
My /etc/postgresql/9.1/main/pg_hba.conf
looks like this:
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
host all all 0.0.0.0/0 md5
host db_name user_name 0.0.0.0/0 md5
# "local" is for Unix domain socket connections only
local all all peer
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
host replication postgres 127.0.0.1/32 md5
host replication postgres ::1/128 md5
and /etc/postgresql/9.1/main/postgresql.conf looks like this:
# - Connection Settings -
listen_addresses = '*'
#listen_addresses = 'localhost' # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost', '*' = all
# (change requires restart)
port = 5432 # (change requires restart)
I then try to connect on to the remote machine as follows:
psql -h ec2-xxx-xx-xxx-xxx.compute-1.amazonaws.com -d <database_name> -U <username>
where ec2-xxx-xx-xxx-xxx.compute-1.amazonaws.com is my Public DNS.
The above command does not result in any connection, how can i connect?

In this table:
the CIDRs look like you're not allowing any IP in. Shouldn't they be
0.0.0.0/0
instead, like what you have for port 22 (ssh)?
