So, I found this cool chat some days ago ;
https://github.com/AndrewBelt/hack.chat
I managed to install it and everything is working.
The server is at 127.0.0.1:6060 and the client ( running through http-server is at 0.0.0.0:8080.
So I ran it and locally, it works.
So I was wondering what about making this chat public all over Internet using my public IP ?
Go to config.js
Change host to my public IP xx.xxx.xx.x
Then I tried to launch the server using node server.js and here the problem start !
root#user:~/hack.chat# npm start
hack.chat#1.0.0 start /root/hack.chat
node server.js
Started server on 88.169.22.4:6060

I searched what this problem could be, I saw some people sayin' that some process are launched on the same port but when I do a fuser 6060/tcp or fuser 8080/tcp, it show me that no process are currently running on these ports.
--
EDIT: With what I found on the web, this error is from the config.json file. I can't provide my remote address as server but don't know how to fix it
Thanks in advance.
The IP address 0.0.0.0 means that the port will be bound to accept connections from any source address. In other words, the configuration by default allows hack.chat to be used from any IP address. If http-server (or any other static file HTTP server) is also bound to 0.0.0.0, then both the static files and the WebSocket connection will be available to the public.
Problem solved !
The problem was that I didn't opened the 6060 port..
I'm really stupid lol
For the future ones who got the same problem just do this :
Redirection from port 80 to port 8080
Open the port 6060
Set the http-server and the server with IP : 0.0.0.0
And everything should works.
Thanks for the ones who helped me <3

The one thing different was that I saw that for some reason the mongodb service tried and failed a new deploy so I ran one manually.
I also noticed that the IP addressit tries to connect is mongodb's cluster IP but the Node IP of the current running pod is different.
Can someone help me figure out what triggered the connection to break?
Thanks
From within a given Project scope, requests directed toward a hostname of "mongodb" should be routed to the Kubernetes Service named "mongodb" (when available).
To debug this connectivity issue:
Try opening a live terminal within your front-end container using the OpenShift web console. The front-end container must be within the same Project scope as the database service
Type env to list environment variables available to the front-end. If this container was started after the creation of the "mongodb" service, configuration strings should be visible the environment
Run curl $MONGODB_SERVICE_HOST:$MONGODB_SERVICE_PORT from the live terminal to verify the availability of the mongodb service
I have been trying to install jshint through npm that is required for SublimeLinter-jshint.

I have tried this so far:
disabling AVG antivirus
disabling windows Firewall
checking if port 443 is in use by another service using netstat -aon : findstr:443. (nothing is listening in on that port)
tried different versions of nodejs v.5.6.0, v.4.3.0, v.0.1.24
tried multiple internet connections, also tried internet connection with no router
tried "npm cache clean"
tried "npm config set registry https://registry.npmjs.org/" and also "npm config set registry http://registry.npmjs.org/"
I have tried installing a different package (bower) which was successful.
I am not running through a proxy
I am not really sure what to do from here to make this work. Any suggestions would be greatly appreciated. I have attached a link to the debug log below:
https://github.com/npm/npm/files/133529/npm-debug.txt
In case anyone is experiencing a similar issue, I was able to resolve this issue by reinstalling the driver for my network adapter.
So I've deployed my express/mongodb app via git to my Azure Web App, and when I open the app's link it keeps loading and shows a black page, my routes doesn't work, but the static files load just fine.
So I went to see the log, and I got this.

So the issues appears to be in mongodb's connection command, which I currently have it as
mongoose.connect('mongodb://127.0.0.1:3000/myapp');
I've tried changing to localhost instead of 127.0.0.1, and tried a different port, all resulted the same error.
After some googling/stackoverflowing, it appears that there's a 'lock file' in mongodb that I need to remove, then repair/restart the mongodb service.
The problem is that I can't find this file using Azure Console (which is Windows based), and I couldn't run any mongo or mongod command (it is not recognized as an internal or external command).
So what can I do to get my app to work on Azure?
As I know, there are not any databases supplied directly on Azure WebApps. So the issue was caused by no mongodb instance on the address localhost or 127.0.0.1 of your webapp, not the MongoDB connection string incorrect.
You can try to create an instance of MongoDB on Azure, and copy the connection string to change the code mongoose.connect('<the remote connection string>').
As reference, you can refer to the doc Announcing New MongoDB Instances on Microsoft Azure to know MongoDB on Azure and how to get started.
I don`t think there is local mongoDB in Azure App Service environment, try to change to connect to a remote database (e.g host your mongoDB on an Azure Virtual Machine) should fix your issue.
You can follow this post to:
create a mongoDB instance on mongolab(which is supervised by Azure)
setup your nodejs env variable in your Azure web app setting
reference the env variable in your nodejs code to connect to your mongoDB

********** Update *********
This had to do with me changing my ports to those of my ipaddress in config.js so I can test on mobile and table. Any idea how I can do this without changing the ports everytime I reboot the computer so that they are always set to my ipaddress for testing?
**********Original Question ****
I am getting a strange error when starting npm to run my ghost blog. It has happened before and I went back to a previous commit on github. It seems like everytime I get it working through a different method and then stop working and close terminal. Then when I restart its another issues?? Maybe github is causing it. Any help would be great. Tried everything I know how to do.
here is the error message:

You are already using the Ghost port for something else.
Most probably ghost exited the wrong way, or you are using forever/pm2 and the process hasn't closed properly. try killing any 'forever/pm2' instances, then reboot your machine. Worked for me.
To understand what happens, I suggest you try the following to see which process uses the ghost port, then kill the process. http://www.cyberciti.biz/faq/what-process-has-open-linux-port/
And also, you're a bit off-topic, this should be moved to SuperUser.
I am trying to set up a node js based application in one of our lab servers where connectivity to internet is achieved via a proxy. The box is running Ubuntu 13.10. I have configured the network proxy and I am able to connect to internet through Firefox. For apt-get, I have configured the proxy in /etc/apt/apt.conf. This is also working.
After installing node js, when I try to do npm install -g <package> it's giving me errors. I have configured the proxy for npm too. My .npmrc looks like this: (my proxy does not require userid/password).
registry = http://registry.npmjs.org/
proxy = http://<domain>:8080/
https-proxy = http://<domain>:8080
I have tried various options found in forums, but none seems to work for me. (Like setting strict-ssl to false, using --without-ssl --insecure option etc.)
This is the error I am getting currently:
npm http GET http://registry.npmjs.org/express

Any idea, what's going wrong here? I'm stuck with this darn thing for the day ;-(
Thanks!
I haven't been able to get a resolution for this issue, but found a work around - I bundled the packages I require on my laptop and then resorted to offline installation on the lab box. Here is how to do that:
Take for example, mongodb node module. I have it installed on my laptop where I do the development. If you open the package.json file for mongodb module, the dependencies are listed with corresponding version numbers. Mine looks like this:
"dependencies": {
"bson": "0.2.5",
"kerberos": "0.0.3"
},
Update the package.json file to include "bundledDependencies". (the position shouldn't really matter, just that it should be at the same level, as a sibling of "dependencies" in the JSON tree). This is what you need to add:
"bundledDependencies": [
"bson",
"kerberos"
],
Now, while you are within your package's directory (where the package.json file is present), run the command npm pack. That will create a tgz file for you. In my case it created mongodb-1.3.23.tgz. Just copy this file to the box where you want to install it and run npm install ./mongodb-1.3.23.tgz. That should get you through. Since all dependencies are now bundled within this .tgz file, npm won't try to connect to internet for installing any of them.
However, I would still like to know what's going wrong with my internet based installation. That's still a mystery!
