After installing postgres and pgAdmin 4 on Ubuntu 22.04 I want to setup a server listening on localhost.
The pg service is running
but when trying to create a new server I get the following error
I think the terminal error points to the same problem
I think the server is running locally but what am I missing / how can I accept the missing socket connections?
Could you check if the listen_addresses in the postgresql.conf accepts connections from localhost or set it to '*', if no special restriction required

I am trying to setup the basic hello world example.
I am using a t2.micro instance with Ubuntu 14.04 LTS and I have the github code for the example on my local machine.
The url I am using is:
https://localhost:8443/index.html?ws_uri=wss://ec2INSTANCE:8888&ice_servers=[{"urls":"stun:stun.l.google.com"}]#
I do not have the stun or turn configured on the server, but it should be ok since I am passing the stun server to use in the url.
Any advice on this?
I just checked my console and I see this, even though port 8888 is open in AWS Security group that this instance is in
VM8812:35 WebSocket connection to 'wss://ec2Instance:8888/' failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED
I was able to get past the issues that I was seeing
Follow basic instructions on a fresh EC2 (Ubuntu 14.04 LTS), using http://doc-kurento.readthedocs.io/en/stable/installation_guide.html
Add a STUN server in conf
Using stun:173.194.66.127:19302
Tested with http://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/
Secure WS to use WSS, which is required due to HTTPS requirement since Chrome 47, using http://doc-kurento.readthedocs.io/en/stable/mastering/securing-kurento-applications.html#configure-javascript-applications-to-use-https
Uncomment secure section of /etc/kurento/kurento.conf.js
Create the self signed certificate, and placed in /etc/kurento
Go to https://ec2InstanceUrl:8433/kurento and accept insecure connection
Go to example https://ec2InstanceUrl:8443
You must verify that your STUN server is working by seeing something similar to the below image, with the srflx under Component Type.
I am facing some problem while starting sql in xampp. here is the screenshotenter image description here
Your SQL is attempting to use port 3306, which is already in use as stated in the error. Go into
Config > Service and Port Settings > Change 3306 to any other unused ports
Restart the service and see if it works.
I am using Jenkins and currently Jenkins is running fine in the background; however, when i am trying to access Jenkins using browser the homepage of Jenkins is not accessible. When I access it I get "Error reading from remote server ( 502 )". Has anyone encountered such an issue? What could be the workaround?
Try to remove proxy: export http_proxy="" && curl http://servername:portnumber/destinationpath/
or use https instead of http or vice-versa ( check which port is your jenkins running on )
Is it running on apache/nginx/whatever? Restart that. Restart Jenkins once more. Check the server configuration regarding those.
Did restart of iptables post which I have seen the issue to be resolved.
service iptables restart
Hi im trying to run tomcat over the terminal in mac, so i type ./startup.sh to execute the script.The terminal then gives me the following:
Using CATALINA_BASE: /Users/kimmy/Documents/Apache/tomcats/apache-tomcat-7.0.35
Using CATALINA_HOME: /Users/kimmy/Documents/Apache/tomcats/apache-tomcat-7.0.35
Using CATALINA_TMPDIR: /Users/kimmy/Documents/Apache/tomcats/apache-tomcat-7.0.35/temp
Using JRE_HOME: /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
Using CLASSPATH: /Users/kimmy/Documents/Apache/tomcats/apache-tomcat-7.0.35/bin/bootstrap.jar:/Users/kimmy/Documents/Apache/tomcats/apache-tomcat-7.0.35/bin/tomcat-juli.jar
When i try to visit the local host to check if the tomcat server is running the browser says can not connect to server.
Does anyone know what the problem is?
Thanks
tomcat server by default runs on port no 9999 on mac.
To know the port no on which tomcat is running, check the terminal after server is on. check the line "server started on......"
using this port no you can request by following
http://localhost:9999
this will open server page.
Hope this helps.
Have a VPS and access to WHM as cpanel.But how can i access the php.ini and also connect using SSH.With SSH getting error
Failed to connect to server:
Network error: Connection refused.
If there is a proxy that is blocking it?
This question is probably better asked at serverfault. Having said that, by default in common Linux distributions (Ubuntu, for example), SSHD is not running by default.
Verify that you are running an SSH server, and if you are still having issues, this is better taken somewhere more relevant.
