Can anyone help me with installing SSL for Zope on Mandrake? I am having trouble installing M2Crypto acording to the instructions at: http://mars.post1.com/home/ngps/m2/INSTALL.html Fails to build during this part of the install: unzip m2crypto-0.11.zip cd m2crypto-0.11 python setup.py build error message is: gcc -g -O2 -Wall -Wstrict-prototypes -fPIC -I/root/m2crypto-0.11/SWIG -I/usr/include -I/usr/local/include/python2.1 -c SWIG/_m2crypto.c -o build/temp.linux-i686-2.1/_m2crypto.o -DTHREADING SWIG/_m2crypto.c:677:25: openssl/err.h: No such file or directory SWIG/_m2crypto.c:678:26: openssl/rand.h: No such file or directory SWIG/_m2crypto.c:742:28: openssl/crypto.h: No such file or directory SWIG/_m2crypto.c:745: `CRYPTO_NUM_LOCKS' undeclared here (not in a function) SWIG/_m2crypto.c:746: `CRYPTO_NUM_LOCKS' undeclared here (not in a function) SWIG/_m2crypto.c: In function `threading_locking_callback': SWIG/_m2crypto.c:751: `CRYPTO_LOCK' undeclared (first use in this function) S

RemoteUserFolder and local user attributes
by Brendan O'Connor 04 Aug '03

04 Aug '03

Hello all - I'm using the RemoteUserFolder product in an intranet portal that I've built for my company. So far the feedback has been overwhelmingly positive, with everyone starting to see the light. So far, authentication in my prototype site has been done within Zope. My IT dept supports an authentication mechanism that is done through apache allowing users to login using either their Unix or Windows passwords. It has been expressed to me as a requirement that I be able to use that information for logging users into the portal automatically. This problem would seem to be solved via the RemoteUserFolder since the authentication mechanism they use generates a REMOTE_USER field in the header. Unfortunately, the REMOTE_USER field is stuffed with a unique ID number (the employee ID number) rather than the more user friendly username. It's simple for me to get a mapping from employee ID number to username, but it is very expensive in terms of time. My initial implementation (which is a modification of RemoteUserFolder) just queries a database whenever a user needs to be authenticated to access an object. Naturally, this is very slow. Slow enough, in fact, to drive the load on the web server (normally 0.10-0.50) well over 2 whenever more than 1 person is accessing the portal. So, enough with my longwinded problem description ... I have considered the following solution (and would gladly entertain others, hint hint ..) When a new user is encountered, do the database lookup as part of the auto-add feature of RemoteUserFolder. Store the username as the user name and store the ID number as an attribute. That way, when a user needs to be authenticated, I can just match the ID number with the name within Zope and never have to go back to the database again. Seems reasonable ... only problem is that I can't figure out how to store the ID number as an attribute of the user. Any comments are welcome! Thanks in advance ... Regards, Brendan

Decisions, decisions! Which Python for Zope 2.6.2b5
by Dennis Allison 03 Aug '03

03 Aug '03

The installation notes still say Python 2.1.3. Rumor has it that you can run under Python 2.2 but it's not recommended. In fact, the docs say explicitly not to use it. I have been using Python 2.3 through the beta period and like it--the new language features have quickly become part of my programming lexicon. Zope 2.7 is not ready for prime time use on a production site. As I remember, it will require Python 2.3. I'm setting up a production site where stability and performance are important. Whould I use Python 2.1.3 or Python 2.3? I am planning to use Zope 2.6.2b5. We've been doing our development against 2.6.2b3 and have found it to be stable.

Newbie VHM/Siteroot question
by Vasu Muppalla 03 Aug '03

03 Aug '03

I am using zope standalone and have the SSL modules installed. Now I want to rewrite all management requests to the https ( runnin on port 8443). For this purpose, assume the URL has the string 'manage' in it. I tried using siteaccess, the following script as access rule. <dtml-let stack="_.string.find( URL, 'manage')"> <dtml-if expr="stack > 0"> <dtml-call "REQUEST.set('SiteRootPATH', 'https://localhost:8443/')"> <dtml-call "REQUEST['TraversalRequestNameStack'].append('manage')"> <dtml-else> <dtml-call "REQUEST.set('SiteRootPATH', URL)"> </dtml-if> </dtml-let> I get an error that resource is not found, blah blah. Resource is http: GET. With a string 'localhost' instead of 'manage' and SiterootPath = '/', the URL rewriting works. The error happens because of manage - dunno why. Is it possible to do it using only VHM and no siteroot ? TIA, Vasu

Zope threads on Slackware
by Heimo Laukkanen 03 Aug '03

03 Aug '03

Hi all, urgent need for help on Zope threads on Slackware linux. I'm not familiar with slackware and the sysadmin is not familiar with Python, but the situation is that somehow Zope does not run more than one thread on the system. Python is compiled with threads - and there seemed to be no errors on that. Zope is configured to start 4 threads. It looks like Zope tries to start the threads, but these threads die very fast ( in microseconds or so ). Any help on debugging would be appreciated. -huima

Exception Handling Email
by Kevin Gill 02 Aug '03

02 Aug '03

On my web-site, when an exception occurs, I email the http request and the exception traceback to myself. A few times when I have done something really stupid, I have created an even which results in a large number of exceptions. In the last week I have got nearly 1000 exception reports. I am planning to do something which suppresses duplicate reports or at least would suppress them for an hour or so. Has this been done already and is there a recipe somewhere? Thanks Kevin Gill

Automatic authenticating users in Zope behind IIS
by Carsten Gehling 02 Aug '03

02 Aug '03

I am going to use Zope to form an intranet for a TV station. The situation is, that all users (using Windows 2000 workstation and Internet Explorer 5.5) are logging on to an Active Directory Server. The intranet is to be implemented with Zope running behind IIS 5.0 (or the newer one if it can solve the problem). IIS and IE has a special function: If the directory security is set to ONLY "NT Challenge/response" AND the intranet URL is set in IE to the security level "Local Intranet", the user need not make a separate authentication to enter the intranet. Instead IE sends to IIS the user details previously entered when loggin onto the Active Directory Server. IIS then validates the user against the same AD (and also checks with user permissions on the directory/website). If the user is authenticated and have permissions to execute scripts, the script in question is called with an extra server variable called "LOGON_USER". This work with both ASP and eg. PHP. I would like this to work with Zope as well, so that Zope does not display an authentication dialog box. I see two ways to do this, however I do not know if it would work, or even how: 1) Zope is run behind IIS with PCGI. All users with access to the intranet must be added to the permissions for the intranet's root rolder. Zope user folders are made with the special LDAPUserFolder 2) Zope is run as a standalone server. Zope must simulate IIS's challenge/response system. Zope user folders are made with the special LDAPUserFolder Have anyone tried this before? I'm still at the level of getting PCGI to work properly. ;-) Any help is much appreciated. - Carsten

When Inheritance ISN'T Such A Good Idea...
by beno 02 Aug '03

02 Aug '03

Hi; Search engines don't like Web sites with deep directory structures. I use such structure to develop my Web sites to take advantage of inheritance. I keep all my Python scripts in a separate directory as well as the basic content of each page. This, of course, makes things neat and tidy in my Zope. So I don't want to simply throw everything in the root dir! Is there a way to call scripts and Template Pages from other pages such that it renders as a simple URL without deep directories (e.g., http://mysite.com/main.html ) or frames? TIA, beno

I am trying to check to see if Zope 2.6.2b4 is actually gzipping content before sending it and every tool I use says it is not:. http://leknor.com/code/gziped.php http://www.desilva.biz/gzip-test.php Neither seem to show the site (or any Zope site) as Gzipped. Just me or... BZ
