Trying to connect to my django website (from the browser) that's stored on the GCP virtual machine.
Everything works fine if I'm accessing it internally using internal IP or localhost.
However, I can't access website with external IP.
No logs in django that would say someone trying to access if I'm trying with external IP.
I have http, https traffic enabled on instance.
Firewall rule to allow port 80:
Here is Test-Net results.
Searched the web for answers but nothing looks wrong in my settings..
Any ideas would be appreciated.
UPDATE:
Do not create or change egress rules unless you know exactly what they do. They are not necessary for ingress rules (VPC Firewalls automatically allow return traffic):
I've changed all firewall rules back how they were so now only port 80 is allowed.
You have an ingress rule for the target http-server. Is that target flag set on the VM instance?
What is the output from sudo lsof -i -P -n | grep LISTEN? Your Django server must be listening on 0.0.0.0.0 instead of localhost.
I have 0.0.0.0 with port 80 at django terminal.
I use windows 2016 server so don't know the powershell function that would display what you asked for.
Here is netstat listening ports for django.

I've been working on a website for the past month, and now its time for me to host the django website onto a private server. Is there a detailed method on how I'm supposed to host the website onto a specific IP address assigned to my system?
This is my first time dealing with hosting a server and i dont know much about it.
Also, once i host it, How do i change the link from being the IP address to an actual link like "12345678.com" or something like that?
(The website should be hosted in such a way that only the people who are in the same network/lan connection should have access to the website.)
I have wamp on the system and the system has a Windows Server OS (if this info helps)
you can run your codes with manage command like this
python manage.py runserver 0.0.0.0:8000
but its strongly recommended to run your code with a web server like nginx or apache read this tutorial to run your site on a linux server
https://www.digitalocean.com/community/tutorials/how-to-set-up-uwsgi-and-nginx-to-serve-python-apps-on-ubuntu-14-04
on windows you can use IIS but its not recommended. its performance is not good
to use 1234567890.com instead of using server ip address you must setup a DNS server on your local network. in linux you can use bind and windows server have its own DNS server. but in your DHCP configuration you must set this DNS server as clients DNS.
I am working on a Django project where I am trying to use Jquery, I used a command-:
python -m HTTP.server on my Windows PowerShell, server is started but when I trying to use the address http://0.0.0.0:8000 in my browser it is showing an error as follow-
This site can’t be reached
The webpage at http://0.0.0.0:8000/ might be temporarily down or it may have moved permanently to a new web address.
ERR_ADDRESS_INVALID
my firewall is allowing access.
please help.
0.0.0.0 is not a real address; it's a special value that means "listen on every IPv4 network you can listen on".
To connect, you have to specify one of those addresses.
If your browser is on the same machine as the server, you want to use the localhost address, like either of the following:
http://localhost:8000
http://127.0.0.1:8000
That 127.0.0.1 is a real address, but it's a special one meaning "the same machine I'm on, without going through the network" (and localhost is a special name for that address).
If your server is on a different machine from the browser, you have to use an IP address or name that actually maps to the server. For example, if you started the server by doing ssh 192.168.1.100 and then running it in the shell there, you'll connect like this:
http://192.168.1.100:8000
Closing the django server (ctrl + c on termial) and then restarting my computer worked for me
I'm trying to connect to my website from another node on another network. If the nodes are in the same network, i can connect to the website without a problem.
I've forwarded port for ssh and Django (8000), I also have apache ready on port 9080.
ssh and apache ports work fine when connecting to them from external ip address, Django does not for some reason.
First, i tried to run the server on port 8000:
python manage.py runserver 0.0.0.0:8000
This works completely fine when connecting from the node that is in the same network as the server, but for some reason, whenever i try to access it from external ip address, the connection is refused.
To make sure it was Django, I also tried running the server on the same port as Apache (9080), although, i didn't expect "errorless" response, since i knew that port was occupied. But there was no change at all, I was still getting the same Apache page that i would get before.
I also tried allowing port 8000 on firewall:
sudo ufw allow 8000/tcp
But pretty sure this is not the problem, since this Debian came without any firewall.
I also tried to empty ALLOWED_HOSTS in settings, but there was no progression.
It seems like Django has no effect for external connections, what could be the reason?
I also struggle to understand the purpose of other http web server platforms in this case (e.g Apache, Nginx), Isn't Django creating a webserver itself along with its custom wsgi?
Firewall is not the problem, neither is the web server, then may the problem be caused by the Django itself? Maybe it is outer firewall?
It is not clear how you are configuring Apache to forward requests to Django, it seems like you are treating those as two independent components. If you want to use a web server in front of Django (recommended for production envs), you need to configure both Apache and Django.
Then, as you are running django in dev mode (python manage.py runserver 0.0.0.0:8000), you should reach Django in http://server_ip:8000 regardless of Apache, perhaps there is another firewall blocking the connection. Use tracert / traceroute to find out where the connection is blocked.
FInally, for production environments, it is recommended to use a web server in front of Django to increase security and performance. See the docs for further information.
My guess is that you have another firewall blocking the port. You opened the local firewall using ufw, but there may be an outer firewall.
python manage.py runserver 0.0.0.0:8000 starts correctly? If so, keep an eye in the log.
Inside the server, do a request wget http://localhost:8000. The request should be logged
If you can reach Apache in port 9080 from outside the server, you can:
Use nmap to find the opened / closed / filtered ports in the server to find if there is another firewall inbetween.
Configure Apache to forward requests to Django, although this does not solve the problem
In your question you say that you have forwarded port for ssh and Django. What exactly is this? Are you sure that you have not misconfigured your ssh server to listen in port 8000?
I currently have a Linux Debian VM set up through Google Cloud Platform. I have docker installed and would like to start running application containers within it.
I'm following the documentation under Docker's website Found Here under
"Running a web application in Docker" I download the image and run it with no issue. I then run $sudo docker ps and get the port which is 0.0.0.0:32768->5000/tcp
I then try to browse to the website at http://"MyExternalVMIP":32768 but the applications doesn't come up. Am I missing something?
First, test to see if your service works at all. To do this, from the VM itself, run:
wget http://localhost:32768
or
curl http://localhost:32768
If that works, that means the service is operating properly, so let's move further with the debugging.
There may be two firewalls that are blocking external access to your docker process:
the VM's OS firewall
Google Compute Engine firewall
You can see if you're affected by the first issue by accessing the URL from the VM itself and from another VM on the same GCE network (use the VM name in the URL, not the external IP):
wget http://[vm-name]:32768
To fix the first issue, you would have to either open up the single port (recommended):
iptables -I INPUT -p tcp -s 0.0.0.0/0 --dport 32768 -j ACCEPT
or disable firewall entirely, e.g., by stopping iptables (not recommended).
If, after fixing this, you can access the URL from another host on the same GCE network, but still can't access it from outside of Google Compute Engine, you're affected by the second issue. To fix it, you will need to open the port in the GCE firewall; this can also be done via the web UI in the Developers Console.
Create an entry in your local ssh config file as below with specific local forward port. In my case its an example of yarn's IP, which I want to access in browser.
Host hadoop
HostName <External-IP>
User <Local-machine-username>
IdentityFile ~/.ssh/<private-key-for-above-user>
LocalForward 8089 <Internal-IP>:8088
I work on a project in which I need a python web server. This project is hosted on Amazon EC2 (ubuntu).
I have made two unsuccessful attempts so far:
run python -m SimpleHTTPServer 8080. It works if I launch a browser on the EC2 instance and head to localhost:8080 or <ec2-public-IP>:8080. However I can't access the server from a browser on a remote machine (using <ec2-public-IP>:8080).
create a python class which allows me to specify both the IP address and port to serve files. Same problem as 1.
There are several questions on SO concerning Python web server on EC2, but none seems to answer my question: what should I do in order to access the python web server remotely ?
One more point: I don't want to use a Python web framework (Django or anything else): I'll use the web server to build a kind of REST API, not for serving HTML content.
you should open the 8080 port and ip limitation in security croups, such as:
All TCP TCP 0 - 65535 0.0.0.0/0
the last item means this server will accept every request from any ip and port, you also
You passble need to IAM in AWS.
Aws set security permission that need to open up port so you only localhost links your webservice
aws link
