I'm have an issue with running the built in Python server that comes with 3.1, this may or may not be an issue with Python, in fact it probably isn't.
I start my server in the correct directory with "python -m http.server 8000" as the documentation suggests (http://docs.python.org/release/3.1.3/library/http.server.html).
When I navigate to that port on my local network with another computer using the url 192.168.2.104:8000 (my local ip and the port) my page loads. When I use my global IP, however, it stops working. Port 8000 is forwarded correctly. I used www.yougetsignal.com to verify that port 8000 was open using my global IP. Why in the world would Chrome be saying "Oops! Google Chrome could not connect to [REDACTED]:8000" then? Other server applications (such as my Minecraft server) work just fine. Is there something I'm missing? Furthermore, why would yougetsignal connect to my port but not Chrome?
With most routers ports are only mapped when someone connects from the outside (internet/WAN). You're testing it from your LAN so basically you're connecting to your router when you use your public IP. Ask a friend to test, i.e. from an outside connection.

I'm trying out the command python http.server from the command line, and am trying to access the server. I can access easily from localhost, but whenever I try to use a remote connection, I am unable to connect.
I've tried different ports, and it doesn't look like my firewall is blocking any connections.
From the command line, I run
python3 -m http.server 8000
which returns
Serving HTTP on 0.0.0.0 port 8000 ...
However, I can only connect to the server from localhost.
sudo iptables -S
returns the following:
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
I expect to be able to connect from a remote host with the url http://10.247.30.125:8000 (my ip address), but I am unable to do so. The same url works fine on localhost.
I figured out what was going on. Did some reading about IP and NAT, and noticed that any ip address beginning with a 10 is reserved for private ip addresses. So, trying to connect to 10.247.30.125:8000 from anywhere other than my own network (so while not connected to my wifi) doesn't work. To be able to connect from an external network, I would need to set up port forwarding (like Reedinationer suggested), and I would need to use my router's public IP address rather than my computer's private IP address. I would set up a port forward from my router to direct external traffic to my computer, which would allow me to connect to my personal computer from an external network.
Thanks to everyone who responded!
port is missing from the url try this url it should work "http://10.247.30.125:8000"
Lately I've been playing with Python to discover its potential and I've just stumbled upon SimpleHTTPServer.
I'm on Windows 10.
I run:
python -m SimpleHTTPServer
the output is:
Serving HTTP on 0.0.0.0 port 8000 ...
I've opened the browser both on smartphone and tablet, but none of them can connect to the server when I type "http://127.0.0.1:8000".
(Translating from italian, maybe is not the exact translation)
iPad: "Safari can't open the page because the server has stopped responding"
Android: "WebPage does not respond. the webpage may be temporarily not available or it could have been moved to another address"
Why does it not work? How do I fix this?
Maybe your firewall is blocking access to python based server
Try this:
Open windows firewall
click on "allow an app or feature..." on the left side of the opened window
search for python in the list and check both the boxes private and public
It should work now
127.0.0.1 is always the IP address of the local system (its associated hostname is "localhost"). In other words, if you type 127.0.0.1:8000 on your tablet or Android device, the browser on that device will try to connect to a server running on the same device, listening on port 8000. You'll need to find out the IP address of the computer you're running Python on, and type that instead. You can use the ifconfig command on Unix, or ipconfig on Windows.
I am SSHing to a server, where Flask is set up. When I execute the flask application, the terminal says Running on http://0.0.0.0:80/, as is written in the file.
Is there any way to view this site on my local machine? Going to the domain above on my local machine just gives a Site Not Found error.
Do I need to just change the IP, or is this not possible?
In the Internet Protocol Version 4, the address 0.0.0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target...
In the context of servers, 0.0.0.0 means "all IPv4 addresses on the local machine"
-- Wikipedia: 0.0.0.0
Key words being "on the local machine". Which means http://0.0.0.0:80/ is not the actual address of the server, just the address it is "listening on".
You need to use the public IP address of the server that you are accessing. If you SSH'd into this machine, you should be able to use the same IP address or hostname to access the now running webserver.
I have an apache server setup on a Pi, and i'm trying to learn Flask. I set it up so that The 'view' from the index '/' returns "hello world". then i ran my main program. nothing happens from the browser on the PC i'm SSH'ing from,I just get an error saying , but when i used the Pi directly and went to http:localhost:5000/ i got a response.I read about setting Host to '0.0.0.0' but that didnt help. how can i get my Flask to accept all connections? does it make a difference that I have an 'index.html' in '/'?
you need to configure your firewall on your server/workstation to allow connections on port 5000. setting the ip to 0.0.0.0 allows connections to your machine but only if you have the port open. also, you will need to connect via the ip of your machine and not localhost since localhost will only work from the machine where the server is running.
I try to setup a simple webinterface with cherrypy & python.
The page is visible over localhost:8080. If I try a different computer on the same LAN and try to connect with it via 192.168.1.100:8080 it doesn't work however. Do I need to open some ports? I thought this would not be needed with linux.
OS: Ubuntu on both systems
Tried Browsers Chrome & midori
Make sure to bind your server to 0.0.0.0:8080 instead of localhost:8080.
localhost always resolves to the loopback interface, which is only reachable from the same host.
0.0.0.0 on the other hand means "all interfaces" (also known as INADDR_ANY).
For details read up about INADDR_LOOPBACK and INADDR_ANY in the ip(7) manpage.
