There are similar questions but nothing worked for me. I have already added this line to my pg_hba.conf:
host all all all trust
And this one to my postgresql.conf:
listen_addresses = '*'
My networking settings in the Vagrantfile are:
config.vm.network "private_network", ip: "10.0.0.0"
config.vm.network :forwarded_port, guest: 3000, host: 3000, auto_correct: true
When I try to connect from the host, I get:
$ psql -h 10.0.0.0 -U <username> -d <database>
psql: could not connect to server: Permission denied
Is the server running on host "10.0.0.0" and accepting
TCP/IP connections on port 5432?
The same command from the guest works with no problems. What am I missing??
[UPDATE]
I changed the private network ip to "192.168.1.77" (got it from a working example) and it worked. Still don't know why 10.0.0.0 wasn't good though, since it is in the reserved private address space, so I'll leave the question unanswered.
You need to forward the postgres port, you're only forwarding 3000, not 5432.
I believe the reason you could not connect is that technically 10.0.0.0 is the network address of the range 10.0.0.0/8 (and 10.255.255.255 is the broadcast address and should also not work). The first address of each range is the network address and is not allowed to be a routable host (similarly 192.168.0.0 should fail in the same way since it's a 16-bit block).
In addition to forwarding port 5432 to another port on my host machine in my Vagrantfile, I added the following to my pg_hba.conf file in my vagrant machine, restarted postgresql, and it finally allowed me to connect from the host:
host all all 0.0.0.0/0 md5
I found the suggestion here: https://github.com/laravel/framework/issues/11339

I am unable to connect to postgres database through remote host using psycopg2 and getting the error like
Error:
File "/usr/lib64/python2.7/site-packages/psycopg2/__init__.py", line 126, in connect
conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: could not connect to server: Connection timed out
Is the server running on host "192.x.x.x" and accepting
TCP/IP connections on port 5432?
Note: I have made following changes
1.updated the pg_hba config file
host all all 0.0.0.1/32 trust
2.updated the postgresql file
listen_addresses = '*'
3.changed the firewall rule to allow connection from port 5432
What else I have to do to make it work?
For others that might encounter the same issue, here are some things you can try.
Make sure the service is listening on the needed interfaces
sudo ss -lntp | grep 5432
If you see something like 127.0.0.1:5432 or ::1:5432 this means localhost.
Tweak postgresql.conf:
listen_addresses='192.168.1.2, 127.0.0.1'
You can also use '*' which means any interface but depending on your network configuration it might be dangerous.
Make sure the listen_addresses line isn't commented (as was the case above) and restart the service after making changes.
Check your firewall configuration
After making sure the service is listening on the correct interface make sure your firewall(s), if any, permit the client to connect to the service (this can mean your local firewall, a network device sitting between the client and the service).
Check pg_hba.conf
This file controls PostgreSQL's host-based authentication mechanism:
# TYPE DATABASE USER ADDRESS METHOD
host all all 192.168.1.3/32 md5
The line above allows all users to connect from 192.168.1.3 if they provide the required password; if you want to allow a whole subnet you can use something like 192.168.1.0/24.
If you suspect an issue with psycopg2 or Python you can test the connectivity using PostgreSQL's client: psql:
psql -U postgres -h 192.168.1.2 db_name
I'm having issues connecting to my PostgreSQL database from an online source.
PostgreSQL seems to be setup up fine it is running on it's default port 5432 and the postgresql.conf has the following line
listen_addresses = '*'
And the pg_hba.conf has the following
host dbname usname all md5
I can connect to the PostgreSQL database from a different machine using the following credentials in pgadmin
Name local
Host 192.xx.xx.xx
Port 5432
Maintenance DB dbname
Username usname
Password psword
Using these I can connect perfectly it seems to work fine.
Then I forwarded the port 192.xx.xx.xx:5432 on the ADSL router and checked it using the public IP address 197.xx.xx.xx (visible to the internet IP)
http://www.canyouseeme.org/
Where I can see the port was forwarded ok.
However when I try to connect using
Name online
Host 197.xx.xx.xx
Port 5432
Maintenance DB dbname
Username usname
Password psword
I get the server doesn't listen error message
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "197.xx.xx.xx" and accepting TCP/IP connections on port 5432?
Why is this? Do I need to add an extra step to making it accept connections through port forwarding?
I am trying to connect to Postgresql using the PGAdmin III client in Windows 8.1. Postgresql is installed in a local copy of Vagrant (Ubuntu 14.04) on my Windows machine. It's up and running on Vagrant:
LISTENING
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 814/postgres
VERIFIED USER/PASS/LOCAL CONNECTION
I can access Postgresql locally in Vagrant via SSH in Windows:
vagrant#precise32:/etc/postgresql/9.1/main$ psql -h localhost testdb myuser
Password for user myuser:
psql (9.1.15)
SSL connection (<removed)
Type "help" for help.
testdb=> \quit
PG_HBA.CONF
I added this to my pg_hba.conf file:
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all <my IP> md5
VAGRANT CONFIG
My Vagrant config is set to port forward to 5432:
# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing "localhost:8080" will access port 80 on the guest machine.
config.vm.network "forwarded_port", guest: 5432, host: 15432
POSTGRESQL.CONF
And my postgresql.conf file is set to listen on all IP's:
#listen_addresses = '*' # what IP address(es) to listen on;
PGADMIN ERROR
So, what am I missing here when I try to connect as a guest via PGAdmin to the host and I get the following message, which indicates it sees it but something is not letting me through?:
An error has occurred:
Error connecting to the server: server closed the connection unexpectedly
This probably means the server terminated abnormally before or while processing the request.
PGADMIN CONNECTION INFO
Host: localhost
Port: 15432
Service: <blank>
Maintenance DB: postgres
Username: Myuser (verified)
Password: ****** (verified)

In your Vagrant config add a IP (if not set) eg:
config.vm.network :forwarded_port, host: 15432, guest: 5432
config.vm.network :private_network, ip: "192.168.111.222"
Now from PGAdmin in Windows connect to host 192.168.111.222, port 5432.
Worked for me although I'm not know why.. :P
I dont know what you mean with in pg_hba.conf but in vagrant enviroment you should use ip like 10.0.2.2/24 instead your machine network address.
I had the same problem in linux, and i think in windows this can happen too. In my postgresql.conf the port variable was defined in two places. First with 5432 value, and second with 5435 value.
Running telnet vm_ip 5435, i was able to connect to the server running in the vm.
In my case my vm was running with public_network option, so i have a external ip. In this case, you don't need to forward a port, once you will access the vm,for example, with 192.168.60.15:5435 address.
Please read before replying it as duplicate (as it perhaps can happen). I am running my postmaster (postgres) server. See below for 'sudo netstat -anp|grep 5432' output?
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 29606/postmaster
unix 2 [ ACC ] STREAM LISTENING 1650581 29606/postmaster /var/run/postgresql/.s.PGSQL.5432
unix 2 [ ACC ] STREAM LISTENING 1650582 29606/postmaster /tmp/.s.PGSQL.5432
I am able to connect from localhost using
psql -h localhost (OR 127.0.0.1) -d <DB> -U user -W
But when I try to connect from other hosts using tcp, by specifying
psql -h ip_add_postmaster -d <DB> -U user -W
It throws:
psql: could not connect to server: Connection refused
Is the server running on host XXXXXX and accepting TCP/IP connections on port 5432?
What's wrong here?
pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# "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
In postgresql.conf,
listen_addresses = 'localhost, 127.0.0.1, ip_add_postmaster'
Note: ip_add_postmaster is same as my Elastic IP and not public DNS. If this information
matters.
What am I doing wrong here? Machine is hosted on Amazon EC2 and have open the port 5432.
As your netstat output indicates, it's listening at 127.0.0.1:5432 which is localhost. That is only connectable from localhost ;)
Set listen_addresses='*' in your config and it will work.
[edit]
Other things to check:
is the amazon firewall blocking anything?
is iptables blocking anything?
But first make sure the listening address is correct, your netstat output shows that it won't work like this.
listen_addresses='localhost, private_ip' fixed the issue. I was not able to start postmaster server on elastic IPs. Once postgres server started o localhost and private IPs, I was able to connect.
One other issue I have found was if you end up with two Postgres installations, the second one can choose non-default port (in my case it was 5433 i/o 5432). So checking the port in postgresql.conf might be a good idea.
I ran into this issue and tried all sorts of fixes I found across SO, and want to add a simple solution that worked for me after realizing it had to do with permissions in my case.
Simply, if you're running a psql server on Windows, you are initially restricted to the default postgres superuser for logging in, launching the server, and so on.
So, first try running from the command line:
psql -U postgres -h localhost -p 5432
and enter your password at the prompt. If you've managed to login and the server is up, then it was a permissions issues. From here, you can create a role for yourself that has login privileges to whatever database you are trying to run.
If the error persists, then consider checking postgresql.conf as mentioned above, to make sure default IP is set to * or localhost, and the port set to 5432 or whatever port you want as default.
I also ran into the same issue. On debugging, it was nothing related to the port, but due to some missing directories in the Postgres folder.
While updating Mac OS (from 10.13.1 -> 10.13.13), some folders in the directory /usr/local/var/postgres/ gets deleted. The fix was the adding the missing directories:
mkdir /usr/local/var/postgres/pg_tblspc
mkdir /usr/local/var/postgres/pg_twophase
mkdir /usr/local/var/postgres/pg_stat
mkdir /usr/local/var/postgres/pg_stat_tmp
mkdir /usr/local/var/postgres/pg_replslot
mkdir /usr/local/var/postgres/pg_snapshots
mkdir /usr/local/var/postgres/pg_logical/{snapshots,mappings}
I have a VM set up with Vagrant that has Postgres running on it (on port 5432), forwarded to port 8280 on the host machine.
I have set the password for the default user and I can connect locally just fine.
I have been trying to set up access from the host machine over port 8280, and I have been unable to get it working with 'MD5' as the trust method.
I have set up postgresql.conf to listen on all addresses:
# postgresql.conf
listen_addresses = '*'
and I have configured pg_hab.conf as follows:
# pg_hab.conf
#TYPE DATABASE USER CIDR-ADDRESS METHOD
host all all 0.0.0.0/0 md5
With all of these settings, if I run the following command from my host machine:
psql --host=127.0.0.1 --port=8280 --username=postgres -d mydb -c '\l'
I am prompted for the password, and then I get:
psql: FATAL: password authentication failed for user "postgres"
If I then change the METHOD from 'md5' to 'trust' I'm not asked for a password and I can connect as expected. My question is - why can't I connect using 'md5', which is what I want to be able to do? I know that the password I am entering is correct (I have changed it), but for some reason it isn't working.
I had the same exact problem. The issue was on the host side, basically the firewall was blocking the port I was using. So this is what I did (I am using OSX Mavericks)
Open the port (Host)
sudo ipfw add 7000 allow tcp from any to any dst-port 7001
Modify Vagrantfile in order to allow portforwarding
config.vm.network "forwarded_port", guest: 5432, host: 7001
Edit postgresql.conf (Guest)
listen_addresses = '*'
Edit pg_hba.conf (you might want to tune this better)
host all all 0.0.0.0/0 md5
Now, from the host connect normally using the port (in my case 7001) and 'localhost' as host address
You need to set a password for the postgres user. It does not have one by default, so you cannot connect.
ALTER USER postgres PASSWORD 'somepassword';
Your local connections probably work because they're using unix sockets with peer authentication, not TCP/IP. If you use:
psql -h 127.0.0.1 -U postgres postgres
on the VM, you'll probably find that that fails too, because you're actually testing TCP/IP based connections now.
