Introduction

ZServerSSL adds to Zope's ZServer the following:

• HTTPS server
• WebDAV-source-over-HTTPS server

With the HTTPS server, ZServerSSL also provides WebDAV-over-HTTPS and XMLRPC-over-HTTPS access to Zope.

These instructions apply to both Un*x and Windows installations of Zope 2.6.1. To avoid cluttering the presentation, Windows pathnames are shown in Un*x fashion.

Preparation

1. Download M2Crypto 0.11, contained in the file m2crypto-0.11.zip.
2. Unpack m2crypto-0.11.zip. This will create a directory m2crypto-0.11. Henceforth, we refer to this directory as $M2.
3. Install M2Crypto per the instructions in $M2/INSTALL.

The ZServerSSL distribution is in $M2/demo/Zope. We shall refer to this directory as $ZSSL.

Installation

Below, we refer to your Zope top-level directory as $ZOPE.

1. Copy $ZSSL/z2s.py into $ZOPE.

2. Depending on your operating system, modify $ZOPE/start or $ZOPE/start.bat to invoke $ZOPE/z2s.py, instead of $ZOPE/z2.py. The files $ZSSL/starts and $ZSSL/starts.bat serve as examples.

3. Copy $ZSSL/dh1024.pem into $ZOPE. This file contains Diffie-Hellman parameters for use by the SSL protocol.

4. Copy $ZSSL/randpool.dat into $ZOPE. This file contains seed material for the OpenSSL PRNG. Alternatively, create $ZOPE/randpool.dat thusly:

   $ dd if=/dev/urandom of=randpool.dat bs=1024 count=1
   

5. Copy $ZSSL/ca.pem to $ZOPE. This file contains an example Certification Authority (CA) certificate. For information on operating your own CA, see http://www.post1.com/home/ngps/m2/howto.ca.html or one of numerous similar documents available on the web.

6. Copy $ZSSL/server.pem to $ZOPE. This file contains an RSA key pair and its X.509v3 certificate issued by the above CA. You may also create your own key/certificate bundle.

7. Copy $ZSSL/ZServer/HTTPS_Server.py to $ZOPE/ZServer.

8. Copy $ZSSL/ZServer/__init__.py to $ZOPE/ZServer. This overwrites the existing $ZOPE/ZServer/__init__.py. Alternatively, apply the following patch to $ZOPE/ZServer/__init__.py:

9. Copy $ZSSL/ZServer/medusa/https_server.py to $ZOPE/ZServer/medusa.

10. Stop Zope, if it is running.

11. Start Zope with ZServerSSL thusly:

    ./starts -X -f 9021 -w 9080 -W 9081 -y 9443 -Y 9444
    

    This starts the following:

    • an FTP server on port 9021
    • a HTTP server on port 9080
    • a WebDAV-source server on port 9081
    • a HTTPS server on port 9443
    • a WebDAV-source-over-HTTPS server on port 9444

Testing

Below, we assume your Zope server is running on localhost.
