PyStun
======
A Python STUN client for getting NAT type and external IP
This is a fork of pystun originally created by gaohawk (http://code.google.com/p/pystun/)
PyStun follows RFC 3489: http://www.ietf.org/rfc/rfc3489.txt
A server following STUN-bis hasn't been found on internet so RFC3489 is the
only implementation.
Installation
------------
To install the latest version::
$ pip install pystun
or download/clone the source and install manually using::
$ cd /path/to/pystun/src
$ python setup.py install
If you're hacking on pystun you should use the 'develop' command instead::
$ python setup.py develop
This will make a link to the sources inside your site-packages directory so
that any changes are immediately available for testing.
Usage
-----
From command line::
$ pystun
NAT Type: Full Cone
External IP: <your-ip-here>
External Port: 54320
Pass --help for more options::
% pystun --help
usage: pystun [-h] [-d] [-H STUN_HOST] [-P STUN_PORT] [-i SOURCE_IP]
[-p SOURCE_PORT] [--version]
optional arguments:
-h, --help show this help message and exit
-d, --debug Enable debug logging (default: False)
-H STUN_HOST, --host STUN_HOST
STUN host to use (default: None)
-P STUN_PORT, --host-port STUN_PORT
STUN host port to use (default: 3478)
-i SOURCE_IP, --interface SOURCE_IP
network interface for client (default: 0.0.0.0)
-p SOURCE_PORT, --port SOURCE_PORT
port to listen on for client (default: 54320)
--version show program's version number and exit
From Python::
import stun
nat_type, external_ip, external_port = stun.get_ip_info()
This will rotate through an internal list of STUN servers until a response is
found. If no response is found you will get "Blocked" as the *nat_type* and
**None** for *external_ip* and *external_port*.
If you prefer to use a specific STUN server::
nat_type, external_ip, external_port = stun.get_ip_info(stun_host='stun.ekiga.net')
If you prefer to use a specific STUN server port::
nat_type, external_ip, external_port = stun.get_ip_info(stun_port=3478)
You may also specify the client interface and port that is used although this
is not needed::
sip = "0.0.0.0" # interface to listen on (all)
port = 54320 # port to listen on
nat_type, external_ip, external_port = stun.get_ip_info(sip, port)
