If your OpenSSL ore kerberos header files are not in /usr/include, you may need to supply the -I flag to let the setup script know where to look. The same goes for the libraries of course, use the -L flag. Note that build won't accept these flags, so you have t o run first build_ext and then build! Example:

  • python setup.py build_ext -I/usr/kerberos/include (or wherever your header files are) python setup.py build python setup.py install
  • Install Pycrypto. (python setup.py install)

  • Verify that all the package are installed correctly by importing pyOpenSSL-0.7, twisted, Crypto from a python shell and we are ready to go.

Simple HTTP Proxy Server (proxy.py)

from twisted.web import proxy, http
from twisted.internet import reactor
from twisted.python import log
import sys
log.startLogging(sys.stdout)
 
class ProxyFactory(http.HTTPFactory):
    def __init__(self):
        http.HTTPFactory.__init__(self)
        self.protocol = proxy.Proxy
 
reactor.listenTCP(8080, ProxyFactory())
reactor.run()
  • Execute the above Twisted python example script (python proxy.py) You may see a Deprecation Warning that you can ignore for this example.

[jacob@tux]$ python proxy.py
/usr/lib/python2.3/site-packages/twisted/web/proxy.py:22: DeprecationWarning: twisted.protocols.http has moved to twisted.web.http. See http://twistedmatrix.com/projects/web.
  from twisted.protocols import http

  • Connect your internet browser to the proxy server you just created (localhost:8080) and you have written a simple proxy server using Python and Twisted.
