I have PostgreSQL running on Ubuntu Server and I want to make remote connection with PostgreSQL running on port 5432.
I've checked if I can ping the public IP of ubuntu server from my machine and that works fine.
Next I've changed two files on ubuntu server first I've changed postgresql.conf which looks as below
#------------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#------------------------------------------------------------------------------
# - Connection Settings -
listen_addresses = '*' # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost'; use '*' for all
# (change requires restart)
port = 5432 # (change requires restart)
Next I've added two lines in pg_hba.conf as below
host all all 0.0.0.0/0 trust
host all all ::/0 trust
Finally I checked if firewall is running by running sudo ufw verbose which outputted inactive.
As per my understanding I've allowed PostgreSQL to accept remote connection and firewall is also not present hence nothing is blocking. Still I get the following error.
psycopg2.OperationalError: connection to server at "XXX.XXX.XXX.XXX", port 5432 failed: Connection timed out (0x0000274C/10060)
Is the server running on that host and accepting TCP/IP connections?
How can I fix this error?
Edit
Although I can ping and ssh to the Ubuntu server using public IP but can not telnet.
I checked if port 5432 is open using this link but it turned out to be closed.
i'm facing the following problem.
I've got a PostgreSQL database on a remote server. In order to access it, i need to pass through a SSH Tunnel.
So, the steps of my test are:
create the tunneling
Connect to the db
perform query / queries
I'm able to create the tunnel by using SSHLibrary, and it works:
SSHLibrary.Open Connection 10.xxx.xxx.xx
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel 9191 ${IP_DATABASE} 22
So i go on by using DatabaseLibrary to perform the connection (and i've checked all the fields are right):
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} ${IP_DATABASE} ${PORT_DB}
but i get the following error:
OperationalError: could not connect to server: Connection timed out (0x0000274C/10060)
Is the server running on host "10.xxx.xxx.xx" and accepting
TCP/IP connections on port 5432?
How can i solve it? I think i need to specify in some way that the database connection must be done by using the tunnel but i don't know how to do it.
Here's the complete test code:
*** Settings ***
Library DatabaseLibrary
Library SSHLibrary
*** Variables ***
${IP_DATABASE} 10.xxx.xxx.xx
${PORT_DB} 5432
${DB_NAME} MyNameDB
${SCHEMA_DATABASE} MySchemaDB
${USER_DB} MyUserDB
${PASSWORD_DB} MyPasswordDB
*** Keywords ***
*** Test Cases ***
Connect To DB Via SSH
SSHLibrary.Open Connection 10.xxx.xxx.xx
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel 9191 ${IP_DATABASE} 22
Sleep 2s
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} ${IP_DATABASE} ${PORT_DB}
I would like to do it by using RF, Anyone can help?
Thank's a lot
Ssh tunnels should work in a way that that you establish SSH connection to another host and expose a PORT in localhost that will then tunnel a traffic from that port in localhost to a IP/PORT in the end point of the tunnel ..
So, lets say you have a host at 192.168.100.10 where your robotframework is running and it needs to connect to a database in 192.168.50.100:
If the postgres is accessible via ssh directly:
Connect To DB Via SSH
${IP_DATABASE}= 192.168.50.100
${DB_PORT}= 5432
SSHLibrary.Open Connection ${IP_DATABASE}
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel ${DB_PORT} ${IP_DATABASE} ${DB_PORT}
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} 127.0.0.1 ${PORT_DB}
Now, if you have to use ssh jump host, eg, connect to a ssh server that will then connect to another server where postgres is running, all you need to do is change the tunnel ip address where the traffic will be forward to:
Connect To DB Via SSH
${IP_DATABASE}= 192.168.50.100
${IP_SSH_JUMPHOST}= 192.168.50.1
${DB_PORT}= 5432
SSHLibrary.Open Connection ${IP_JUMPHOST}
SSHLibrary.Login MySSH_User MySSH_Password delay=1
SSHLibrary.Create Local SSH Tunnel ${DB_PORT} ${IP_DATABASE} ${DB_PORT}
DatabaseLibrary.Connect To Database psycopg2 ${DB_NAME} ${USER_DB} ${PASSWORD_DB} 127.0.0.1 ${PORT_DB}
I have wireguard setup on a machine (call it MachineA, with the IP 10.42.0.19). I have my laptop configured with the IP 10.42.0.15, call it LaptopB. I am able to SSH into MachineA from the LaptopB when I connect both peers using ssh root#MachineA. Then, if I wait a while, I can no longer SSH into the MachineA from LaptopB. For example, the same command ssh root#MachineA just hangs.
Using -vvvv shows me this:
$ ssh -vvvv root#10.42.0.19
OpenSSH_8.3p1 Ubuntu-1ubuntu0.1, OpenSSL 1.1.1f 31 Mar 2020
debug1: Reading configuration data /home/xrd/.ssh/config
...
debug2: ssh_connect_direct
debug1: Connecting to 10.42.0.19 [10.42.0.19] port 22.
And, it never connects.
There is a simple fix: from inside the machine, ping any other Wireguard machine on the network. MachineA is a DigitalOcean droplet. If I use the web console to login, and then ping any other peer on the network (say 10.42.0.4), then immediately after the ping starts, the SSH connection completes.
How do I troubleshoot this?
I have not restarted wireguard on either LaptopB nor MachineA. Both appear to be connected.
In my wg0.conf on both ends they are more or less like this:
[Interface]
Address = 10.42.0.19/24
PrivateKey = DontYouWishYouHadThis
DNS = 10.42.0.1,8.8.8.8
[Peer]
PublicKey = SomePublicKeyIsHere
AllowedIPs = 10.42.0.0/24
Endpoint = 33.33.33.33.:51280
Ok, here's the issue: I want to upload a DB I've got locally and I'm using in localhost, but, when I use:
PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U root app_db > app_db.dump
I always get:
pg_dump: [archiver (db)] connection to database "app_db" failed: could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" and accepting
TCP/IP connections on port 5432?
I think the problem is that I'm writing localhost instead of my heroku app address, can anyone tell me how can I get the correct address?
You need to have postgresql installed and running
I have a website deployed on Apache2. The Apache2 server is setup on a VM.
When I try to access the site using a browser from a remote machine (my laptop), I get a connection timed out error.
When I try to access something deployed on Tomcat on the same VM it works fine. But Apache gives a problem.
Please let me know what I am missing.
Thanks.
1) check that the httpd process is running
ps -ef | grep httpd |grep -v grep
2) make sure you are broadcasting on port 80
netstat -atn |grep :80
3) verify in your conf (/etc/httpd/conf.d/*.conf) file that you are binding Apache to port 80
<virtualhost *:80>
or
<virtualhost xxx.xxx.xxx.xxx:80>
Your Tomcat process may be bound to port 80 and the socket is not available.
on centos run this commands:
iptables -I INPUT 4 -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
/etc/init.d/iptables save
