Postgresql via virtual machine

it's been a while since the last time i played with Postgresql, i've recently installed Postgresql on my vmware ubuntu instance.

if you want to connect to your postgresql server via Host, you have to change network configuration from NAT to Bridged, that way your instance could handle connection as its were a standalone machine on the local network.
after that, you have to set postgresql.conf, change "listen_addresses" option (mine was '*').

$ nmap 192.168.1.79

Nmap scan report for 192.168.1.79
Host is up (0.0012s latency).
Not shown: 997 closed ports
PORT     STATE SERVICE
21/tcp   open  ftp
22/tcp   open  ssh
5432/tcp open  postgresql

and then you have to change <b>pg_hba.conf</b>, add the IP address that you want add as a 'client' that will connect to this server, for example:

host    all     all     192.168.1.67/24     trust

and you're done. now you can connect using whatever available pg client.

$ psql -U postgres -h 192.168.1.79 -d postgres
psql (9.0.5, server 9.1.3)
WARNING: psql version 9.0, server version 9.1.
     Some psql features might not work.

Type "help" for help.

postgres=# 

PS:
if you got this error

psql: FATAL:  Peer authentication failed for user "postgres"

edit pg_hba.conf change this line :

local   all             all             Peer

to

local   all             all             trust
