How to access a server running on a local network - python

I'm running a Django based server on a Mac. When running it using the default "python manage.py runserver" I can access it through a browser using "http://127.0.0.1:8000/".
The thing is I want to access it from other machines on the network. When I go to network settings I can see that the IP is for example 10.0.0.15. In the past I used to be able to run a Django based server using "python manage.py runserver 10.0.0.15:8000" and then access it using that address from any other machine in the local network, including the machine running the server.
Now, when I'm trying to access it using "http://10.0.0.15:8000/" even from a browser on the same machine I can see in the terminal that the server has received a request, but I get a Bad Request (400) response. What am I doing wrong?

I tried running python manage.py runserver 0.0.0.0:8000 as Leonardo Andrade suggested. It still didn't work, but it was the first part of the solution. The problem was that the DEBUG setting was False. In that case Django takes into account the ALLOWED_HOSTS setting.
Possible solutions:
Set DEBUG setting to True. This is a good idea for debugging anyway. ALLOWED_HOSTS setting is not taken into account in that case.
Keep DEBUG setting as False and add to ALLOWED_HOSTS '0.0.0.0' or '*' or your local ip (e.g. '10.0.0.15'). This is only for testing purposes. Make sure you don't allow just any hosts when you run a production server.
Of course, run the server on 0.0.0.0:8000.
A nice solution for accessing the server from other machines when the server runs an OS X is to go to Settings->Sharing on your Mac. There, under Computer Name you can see the name other computers can use to access this computer in a local network (e.g. my-mac.local). You can add that name to ALLOWED_HOSTS and then access the server using it (e.g. http://my-mac.local:8000/).

Try to run python manage.py runserver 0.0.0.0:8000

How do I make Django Website public on my local network?

I am building a website for myself and family in Django and React. Every time I ask them to check my process and get their opinions they get a webpage not found error or this site can't be reached. How do I make is so that anyone on my local network can check my page when its running. This is the default in flask, I don't understand why django runs like this? (safety maybe?) I can't find any good information on how to add an allow all to the ALLOWED_HOSTS section in the settings of the main app.
I also know that you can add IP address, But I'm a noob and I don't follow how to get the ip address of all my families devices without alot of work?? Does anyone have a good solution for this??
Django documentation:
When DEBUG is True and ALLOWED_HOSTS is empty, the host is validated
against ['.localhost', '127.0.0.1', '[::1]'].
If you are in debug mode with an empty list, or in non-debug mode also with an empty list, no one in your LAN network could be accessed to your website.
In this case, because you are in a LAN, you could use:
ALLOWED_HOSTS = ['*']
Then run
python manage.py runserver 0.0.0.0:8000
You don't need to open any ports on your router if you are in LAN, but maybe you need to configure your firewall in your local machine.
Otherwise, a web server like nginx or apache is recommended.
It is very simple
just go to your command line and type ipconfig if its windows and ifconfig if it is linux
Note your ip address on your local network
Write that address in allowed hosts in settings.py
Run command python manage.py runserver :
Take any device connect to your local network and in its browser window type servers ip:port number
For eg 192.168.25.1:8080
If all are on the same network then run
python manage.py runserver 0.0.0.0:8000
ALLOWED_HOSTS = ['*']
But this is not your real problem. You'll most likely need to open ports in the firewall of either your local machine or your router (or both) before other machines on the network will be able to reach yours.

Django tutorial: problems accessing development server

I am going through the Django tutorial and am running into problems when trying to view my webpage. I am at the very beginning of the tutorial when I first run the command python manage.py runserver xxx.xxx.xxx.xxx:8000 (replace the x's with my remote server's IP). When I try to navigate to http://xxx.xxx.xxx.xxx:8000 on my local machine, Chrome gives me the error ERR_CONNECTION_REFUSED. I have also tried running the server on 0.0.0.0:8000 and the same issue persists. The port is definitely open and there are no firewalls blocking it - when I plug in my IP and 8000 into this site it claims it is open: http://ping.eu/port-chk/.
I get no error messages on my console from the Django side of things. What could be causing this error? I really don't know much about servers or ports. Thanks in advance.
I am on a virtual Linux server running CentOS 6.4. My local machine is running Mac OS 10.9.5
EDIT:
When I run netstat --listen, port 8000 doesn't show up in the Local Address column, even though my Django dev server claims to be running. Someone mentioned to me that this means my application is not listening on this port. What does this mean and how do I remedy it?
EDIT:
I can access the page through my phone's internet with no issues. What gives?
If you're running Django inside a VM but accessing it from the host Mac, you'll need to forward the port. See the settings in Virtualbox/VMWare/whatever.
Note however that Django runs perfectly well directly on a Mac, so if you're just learning it may be simpler to just install it there.
Don't issue no IP, runserver will tell you where you can connect to when launching it.
Since you're launching it from your VM, you might supply the IP.
Ensure system level routing is okay.
Add your host local IP to the ALLOWED_HOSTS setting.

Accessing the Django embedded server for development inside PyCharm by other hosts inside my local network?

I'm working with PyCharm and I wonder if there's a way to make the Django embedded server accesible for the other hosts in my local network or I need to deploy my app on a dedicated web server such as Apache?
Now, I'm accessing my Django app like this in the browser:
http://localhost:8000/mypage/
and I want other users inside my local network to type:
http://my_private_ip:8000/mypage/
in their browsers and see the same page.
Just run the server (which is Django's embedded server FWIW, not PyCharm's) under http://my_private_ip:8000:
# ./manage.py help runserver
Usage: manage.py runserver [options] [optional port number, or ipaddr:port]
Starts a lightweight Web server for development.
(...)
# ./manage.py runserver my_private_ip:8000
Assuming a Unix environment.
You need to ensure the server is listening not on the lo interface but on all interfaces (or at least the one used to connect to the LAN).
If you can customize the way PyCharm launches the server, use 0.0.0.0 as the host, as in:
python manage.py runserver 0.0.0.0:8000
Your coworkers can then use your LAN IP address. If you don't know it, use $ ip a.

How can I change this Django Application

I was tasked with making some changes to a Django application. I've never worked with Django and I am having trouble figuring out how to get my changes to compile and be available online.
What I know so far is that the application is currently available online. netstat tells me that httpd is listening on port 80. My change was made in the myapp/views.py file.
I tried to restart httpd using services httpd restart but my changes did not take effect. I've been looking into the issue a bit an I believe that I need to run a command along the lines of:
I tried calling python manage.py runserver MY.IP.AD.DR:8000 and I get:
python manage.py runserver 129.64.101.14:8000
Validating models...
0 errors found
Django version 1.4.1, using settings 'cutsheets.settings'
Development server is running at http://MY.IP.AD.DR:8000/
Quit the server with CONTROL-C.
Nice that no errors are found but when I navigate to http://MY.IP.AD.DR:8000/ I just get a "Unable to connect" message from my browser. I tried with port 81 too and had the same problem.
Without knowing exactly how your application is set up, I can't really say exactly how to solve this problem.
I can tell you that it's quite common to use two web servers with Django - one handles the static content, and reverse proxies everything else to a different port where the Django app is listening. Restarting the normal HTTP daemon therefore wouldn't affect the Django app, so you need to restart the one handling the Django app. Until you restart it, the prior version of the code will be running.
I generally use Nginx as my static server and Gunicorn with the Django app, with Supervisor used to run Gunicorn, and this is a common setup. I recommend you take a look at the config for the main web server to see if it forwards anything to another port. If so, you need to see what server is running on that port and restart it.
Also, is there a Fabric configuration (fabfile.py)? A lot of people use Fabric to automate Django deployments, and if there is one then there may be a command already defined for deploying.

Accessing django project in LAN systems

I used django and developed a site which is working fine, and its about to move to production and ready for deployment in a couple of weeks.
So before moving to production, i want to share the site with some of my employees to check the functionality and something else. Actually their systems are connected in LAN with mine.
So my system IP address is something like 192.168.12.135, when we run run django development server its runs at localhost:8000, i mean with the system IP address and with a port 8000 like 192.168.12.135:8000 right.
So i had shared them the project site link as 192.168.12.135:8000, but when they tried on the systems which are connected in LAN, it is not accessible and displaying an error Server not found.
I tried the above same way because recently i used python web.py framework and developed a minimal site , and when we run the server, it by default runs as localhost:8080 , and when i accessed this link from others system that are connected in LAN with mine as 192.168.12.135:8000 , its working fine and is accessible.
So can anyone please let me know
1. How to access the site on the systems that are connected in LAN before moving to production(in some real servers like apache, nginx etc.,).
2. Basically i am new to web developing and this is my first site developed in python, so
i don't know more about servers and deploying a project. So can anyone please let me know
the detailed information about deploying django on different servers
(First of all i am looking for a solution for 1st problem(Accessing in LAN before moving to
production))
If you run
python manage.py runserver 0.0.0.0:8000
your development server will be available on port 8000 to anyone on your LAN and on localhost as well (and it does not depend on your ip address)
You need to explicitly tell the development server to run on your IP rather than localhost.
Try python manage.py runserver your_ip:port.
Though it'll be accessible if you're running through apache or any other webservers other than the development server.
And to your 1st question, I would advice you to host and use a local apache server rather than using development server. Doing so, you can foresee the issues you'll be facing when moving to production.
And to 2nd, there are plenty of resources available configuring Django with different servers. Hail Google. :)
In your settings.py change ALLOWED_HOSTS to
ALLOWED_HOSTS = ['*']
Run your server by entering the following command
python manage.py runserver 0.0.0.0:8000
In order to access the project from another device enter the IP address of the server followed by the port number, which is 8000 in this example.
On windows I did everything you said but one thing was missing at my end to connect through Wi-Fi..
In settings.py:
ALLOWED_HOST = ['*']
Put Network profil in Private mode:
Windows > Settings > Network & Internet > Wi-Fi > (Click on_your_network) > In Network profil select: Private
Exemple: Run your server on the port 8000:
python manage.py runserver 0.0.0.0:8000
Then to access to the server with your other devices connected to the same network, enter the IPv4's server address with the your port (here 8000)
Exemple, if the IPv4's server address is 192.168.20.26 put the folling text directly in your browser:
192.168.20.26:8000
