I'm running a postgres server in a windows 10 virtual machine on my pop-os laptop. I'm trying to connect to it from my host OS (linux). In virtual box I created a port forwarding rule :
I also changed the listening port in the postgres configuration to equal '*'.
The error message I get trying to connect is this:
postgres#pop-os:/home/peyton$ psql -p 5432
psql: error: could not connect to server: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I don't understand this very well so I could really use some help.
Thanks.
The problem is:
psql -p 5432
is saying connect to local socket on Linux machine. Per the error message:
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
You need to do something like:
psql -p 5432 -h 127.0.0.1

I am trying to connect to my local postgres database from PGadmin in container, but it is through following error:
Unable to connect to Server: connection to server at "localhost" (127.0.0.1), port 5432 failed. connection refused is the server running on that host and accepting TCP/IP connections?
configurations i am trying for creating server are as follows:
hostname/address = localhost
port = 5432
username = postgres
my OS configurations
OS = Linux- Ubuntu
Version = 18.04
PS: there are some existing questions regarding this on Stackoverflow, but no solution helped me.
While it runs locally, the docker container is like a different machine. You need to put the IP address of the local host machine instead of localhost.
i have installed Postgresql and struggling to configure it, tried reinstalling but still facing issue, i removed all the files and then installed postgre 9.6 version, but getting below issues.
9.6 main 5432 down postgres /var/lib/postgresql/9.6/main /var/log/postgresql/postgresql-9.6-main.log
When i try to run postgre by using sudo -u postgres psql it gives below output
psql: could not connect to server: No such file or directory

i have tried from other questions as well but can't fix the problem.
Very likely your PostgreSQL client is configured with a different socket directory (/var/run/postgresql) than your server. Check the unix_socket_directories configuration parameter in postgresql.conf.
Chances are that the server is listening on the default dirextory /tmp. Try
psql -h /tmp ...
Of course it could also be that the server is listening on a different port, e.g. 5555 (configuration parameter port). Then run
psql -p 5555 ...
I'm trying to run the odoo docker container and linking it with my local (not container) postgresql.
I tried this command (as suggest here).
docker container run -p 8089:8069 -e HOST=127.0.0.1 -e USER=tux -e PASSWORD=tux --name odoo -t odoo
Ran it and got these errors :
Database connection failure: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Cannot assign requested address
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
I tried to open up the port 5432 with ufw but got the same erros. I also tried to change 127.0.0.1 to 0.0.0.0 but nothing.
Could you help me?
ps : the USER and PASSWORD are corrects, I use them when I run odoo instance in my local.
you might need to add the host network with a flag --network=host
WARNING: Published ports are discarded when using host network mode
that just means you cannot change the port bindings. thats as secure as your machine is.
I have an Ubuntu 14.04 Linux server with MongoDB 3.2.4 running at Digital Ocean as a droplet (one-click Apps).
Pinging the server works (droplet is distroyed after posting this):
ping 198.199.125.101
I created database test and user:
db.createUser({"user": "test", "pwd": "test", "roles": ["dbOwner"]})
In mongod.conf I changed bindIp: 0.0.0.0 and restarted mongoDB
I disabled the firewall and reboot the server. Just for test, just to prove iptables is not the issue (don't do this on a regular server):
sudo ufw disable
The problem is I can't get remote access to the mongo Database
mongo 198.199.125.101:27021/test -u "test" -p "test"
Error message (connection refused):
MongoDB shell version: 3.2.0

exception: connect failed
First run netstat on the mongo machine to verify that the port 27021 is open. netstat -anp should do it.
Then do "telnet 127.0.0.1 27021" to make sure it is open.
Once you are sure the port is open, then use telnet 198.199.125.101 27021 to verify you can connect to the mongo machine on port 27021. If you can, then it has something to do with your app. If not then something is blocking the connection. Some firewall or something. Are you on aws?
As per netstat, can you try mongo 198.199.125.101:27017/test -u "test" -p "test"
getting an error while connecting remotely and the error says something like
could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host x and accepting TCP/IP connections on port 5432?
please help me out
Open your terminal and write
service postgresql status
If it says it is not running than write
service postgresql start
If the service is already running then check the listening port of your postgresql service via
netstat -an | grep postgresql
and the result will show the port it is listening.And then you can connect your database with the command
psql -h localhost -p port_you_found -U postgres
