Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Trying to connect to my PSQL database on my CentOS VM from my Mac using pgAdmin3. Getting the following error:

Access to database denied
The server doesn't grant access to the database: the server reports 
FATAL: no pg_hba.conf entry for host "172.16.30.1", user "gpadmin", database "postgres", SSL off 

The VM's IP address is 172.16.30.139 and hence I'm using it as a host. I have added the following into my pg_hba.conf file:

local all     gpadmin     ident
#host all     gpadmin     127.0.0.1/28      trust
#host all     gpadmin     192.168.249.131/32    trust
local gpperfmon   gpmon                             md5
host     all     all     192.168.2.109   md5

Where 192.168.2.109 is my Macs internal IP address.

Any help would be appreciated.

Edit:

I also ran a tcpdump and then tried connecting and see the following logs (but I don't know how to read them):

192.168.2.109 may be your mac's address on your internal network, but 172.16.30.1 is the mac's address on the virtual network that it uses to communicate with the VM, and that's the address you need to configure in pg_hba.conf.

@mlevit This is exactly right (in fact if you run ifconfig on your Mac you will even see a (virtual) interface with the IP 172.16.30.1, which is created by your VM software...). –  voretaq7 Aug 1 '12 at 15:34
