Listen for all incoming traffic on port

With python, I have compiled the following script:

from socket import *

socket = socket(AF_INET, SOCK_DGRAM)
socket.bind(("127.0.0.1", 80))
while True:
    data, addr = socket.recvfrom(1024)
    print addr[1]

It is supposed to receive all incoming traffic from port 80. However, if I load a webpage, it does not lot anything. Is there a problem with my script?

There seem to be some misconceptions here, and wanted to make clear for future visitors. When you visit a website you don't send packets out of port 80, you send packets from a random port to the port 80 of a different machine. In this case you are expecting to have packets on your port 80 when you are visiting website: this can't happen. This would only apply if you are hosting a website or listening on that port.

If you truly want to listen to all incoming traffic on all interfaces, perhaps try to bind to 0.0.0.0 instead of 127.0.0.1?

And as just stated, your socket pairing is a bit odd. This should get you started:

from socket import *

s = socket(AF_INET, SOCK_STREAM)
s.bind(('0.0.0.0', 80))
s.listen(1)
while True:
    print s.accept()[1]
