[zorp] Zorp GPL-VERSION

[Ivan Lopez]

Hello:
Congratulations for your product.
First: Pardon for my English. I'm a beginner (in English, Zorp and Python)
Second: I`ve intalled zorp 2.0.1 (GPL-VERSION!!!)in my linux box. I want to 
configure zorp as Reverse Proxy (is this posible with this version?). If it 
is, I´m having problems with my installation/configuration.
Below are instances.conf and policy-http.py files:
Instances.conf (grep -v ^.*# /etc/zorp/instances.conf)
--------------
Zhttp --verbose=10  --policy /etc/zorp/policy-http.py

policy-http.py (grep -v ^.*# /etc/zorp/policy-http.py)
--------------


from Zorp.Zorp import *
from Zorp import Zorp
from Zorp.Zone import InetZone
from Zorp.Service import Service
from Zorp.SockAddr import SockAddrInet
from Zorp.Chainer import DirectedChainer
from Zorp import Http
from Zorp.Http import HttpProxy
from Zorp.Listener import Listener

Zorp.firewall_name = 'zorp@bcpc'

InetZone("cpc", "192.168.1.0/24",
	 outbound_services=[],

	 inbound_services=["INhttp"]),

InetZone("local", "127.0.0.0/8",
         inbound_services=["*"],
         outbound_services=[]),

InetZone("internet", "0.0.0.0/0",
         inbound_services=[],
         outbound_services=["INhttp"])


class INhttp(HttpProxy):
    def config(self):
        HttpProxy.config(self)
        self.transparent_mode = 0
def init(Zhttp):

       	Service("INhttp", DirectedChainer(SockAddrInet("192.168.1.100", 
80)),\
                 INhttp)
        Listener(SockAddrInet("aaa.bb.cc.ddd", 80), "INhttp")

When zorp starts I obtain (tail -f syslog):

Feb 18 19:38:48 bcpc Zhttp[31782]: (conntrack/thread): thread exiting;


I don't know why bind() fails  and I don't know why DirectedChainer is not 
in /usr/share/zorp/pylib/Zorp/Chainer.py. Here is the output for (grep 
.*class in this file):

class AbstractChainer:
class ConnectChainer(AbstractChainer):
class FailoverChainer(ConnectChainer):
class SideStackChainer(AbstractChainer):

My environment is:
Debian 3.0.0 r0 (woody)
python 2.1.3-3
python-extclass 1.2-5
Zorp 2.0.0-1
Zorp-modules 2.0.0-1
libzorpll 2.0.18.4-1
libglib2 2.0.6-1

NOTE: When I install zorp I run:
dpkg -i --ignore-depends=libzorpll zorp_2.0-1_i386.deb
because zorp depends from libzorpll and libzorpll depends from zorp. Is this 
cycle OK or I've misintalled zorp?

I can't find the error in my installation/configuration. Can you help me?
Best Regards.
