Important! Keep an eye on your management screens folks

Folks, My ZServer just mailed me this: Zope has encountered a problem publishing your object. Cannot locate object at: /search/manage This suggests to me that someone was probling our site to see if they could get into Zope and twiddle some bits. I use ZServer, not full-blown Zope, so I have no manage pages. Check to make sure your Zope servers are suitably passworded or that management screens are disabled! -- Skip Montanaro (skip(a)mojam.com) Support the Mojam.com Affiliates Program: http://www.mojam.com/affl/ (847)971-7098

view DTML source
by Anders Eriksson 27 Nov '00

27 Nov '00

Hello zopistas, On the zope.org there is a 'method' called view_source, which lets you see the DTML source of a page. I 'borrowed' this code, by using view_source on itself and got this:  <pre>  </pre>   I then created a DMTL-document called 'view_source' with this content. But when I run, using http://swescout.myip.org/index_html/view_source it I get this traceback: Traceback (innermost last): File D:\SweScout\lib\python\ZPublisher\Publish.py, line 222, in publish_module File D:\SweScout\lib\python\ZPublisher\Publish.py, line 187, in publish File D:\SweScout\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: index_html) File D:\SweScout\lib\python\ZPublisher\Publish.py, line 171, in publish File D:\SweScout\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: view_source) File D:\SweScout\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: view_source) File D:\SweScout\lib\python\OFS\DTMLDocument.py, line 177, in __call__ (Object: view_source) File D:\SweScout\lib\python\DocumentTemplate\DT_String.py, line 528, in __call__ (Object: view_source) File D:\SweScout\lib\python\OFS\DTMLMethod.py, line 168, in __call__ (Object: standard_html_header) File D:\SweScout\lib\python\DocumentTemplate\DT_String.py, line 528, in __call__ (Object: standard_html_header) AttributeError: __call__ This is my data: Zope version: Zope 2.2.2 (binary release, python 1.5.2, win32-x86) Python version: 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)] System Platform: win32 Anyone that know why I get this error and how I fix it? -- Best regards, Anders mailto:ame@swipnet.se Science is everything we understand well enough to explain to a computer.

Hi. I trie to install Zope-2.2.2 with mod_pcgi2 and the Apache web server. I follow the steps in the README files, but when I trie to access to the URL http://localhost/pcgi I get the following error message: Zope Error Zope has encountered an error while publishing this resource. Resource not found Sorry, the requested Zope resource does not exist. Check the URL and try again. Troubleshooting Suggestions The URL may be incorrect. The parameters passed to this resource may be incorrect. A resource that this resource relies on may be encountering an error.

clean way to change AUTHENTICATED_USER?
by Kyler B. Laird 27 Nov '00

27 Nov '00

My users need to login with a simple alias ("kyler") which could change. As part of the (PH/X.500) login procedure, I want to set AUTHENTICATED_USER to a better ID ("kyler.b.laird.1"). This will allow the users to continue to change aliases at will without necessitating ownership changes in Zope. (I've done this for years under Apache.) I'm using LoginManager and a PH kludge I wrote to do the authentication for now. I realize I will need to continue to use the alias (as supplied by the user) for indexing there in orcer to use the cache. I just want everything else to see the full ID. I don't have a good grasp of The Big Picture yet, so I'm hesitant to jump right in and add a setUserName method. I'm hoping there's a better way. Any suggestions? Thank you. --kyler

Re: [Zope] CURRENT MEMBERSHIP PRODUCT IS COOL -- was: [Zope] LoginManager / Membership / ZODB as UserSource
by Danny William Adair 27 Nov '00

27 Nov '00

Hi Dirk Dirksen ;-) In my implementation I wanted to avoid MySQL and thelike, because they would have only served as "user sources" for the site's membership functionality and that's it (and I wasn't talking about Ks of users...). So I considered this O.D., and tried to get a ZODB based membership up and running. Well, here we are - see below. Unfortunately, I do not have any experience with hooking up MySQL to the current Membership/LM/ZPatterns trio. And now that the membership product has become a ZODB drop-in solution for me, I guess now there's no reason for me to go at that. I'd rather go for new methods to enhance the product's features. (there has been more than one proposal for this on this list) Sorry with that one. Charlie E Wilkinson is probably your man (check the mail archives).

Re: [Zope-dev] Security Permissions
by Danny William Adair 27 Nov '00

27 Nov '00

Hi Andre, I think these rights are the result of a broken GDChart product. Make sure the class registration in the initialization part says permissions = 'Add ZGDCharts' (see how you have all the characters as separate rights...) But as far as I know this has been discovered right after the initial release and solved right away. I guess you should simply remove your current GDChart Directory and reinstall the product after a restart.

Re: [Zope] [ZOPE} why single quote can't store in gadfly database tables
by rlanham＠speakeasy.net 27 Nov '00

>I found that Single quote ( ' ) cannot be stored in gadfly database table. If gadfly is like every other db, it will store ' but you have to escape it first since it is the delimiter for string vals. In access, sqlserver you add a second ' to escape. That should work, or use backslash.

acquisition/acl_users/permissions: is something broken? 2e post on this pb.
by Gilles Lavaux 27 Nov '00

27 Nov '00

Hello, That's the second time I have this problem, I report it again because the answer I got the last time was not 'sure' (see bottom of mail) and I would like to have an 'definitive' explanation from some Zope guru. I hope my explanation will be clear: I have 3 folders for a project called 'sms': /sms/shtml which is accessible by anonymous /sms/shtml/stations which is not accessible by anonymous, only by 'operator' ans stations users /sms/admin which is accessible only by 'operator' user /sms/acl_users contains the 'operator' user with role 'sms_admin' /sms/shtml/stations/acl_users contains several station users (station1, staiton2.etc...) with role 'station' 1)'operator' user has permission to access /shtml/stations. operator authentication is forced by accessing a '/sms/admin/login' method. 2)a method 'check' is inside the '/sms/shtml' folder, this method (also) display the http authenticated user. My problem: I am logged in as 'operator'. Sometime, accessing '/sms/shtml/stations/check' show me: -Logged in as: Anonymous User and has role(s):Anonymous instead of: -Logged in as: operator and has role(s): sms_admin why???????? (this with IE and Netscape) I just have a guess: the 'operator' user is defined in '/sms/acl_users' and my stationx users are defined in '/sms/shtml/stations/acl_users'. So: is it possible that when I do my 'check' as operator, the acquisition go to the acl_users which contains the stationx users and miss the other acl_users folder (which is two levels above) ? Another investigation: I am logged as operator in a new browser and have the problem, I click on a link for a stationx user but cancel the http authentication, then the problem disappear. I am able to use a workarround, but I would like to understand what cause my problem. Is there a way to display which object has triggered the authentication, and which acl_users folder is used?? Help please... Thanks. Gilles Lavaux > > >Last time reply by Dieter Maurer : The security system does not use the full acquisition context but only the containment. This is a security feature to prevent a user with partial management rights in a subfolder to affect permissions for objects outside its area. I think (am not sure!) that in your case, the "protected" context is not used as your objects are in fact outside "protected". Dieter

WebDav-support / Index_html versus index.html
by Pieter Biemond 27 Nov '00

27 Nov '00

Hi, I'm planning to setup a Zope server for our company. We have a lot of people with HTML-knowledge and a lot of people who would like to use Microsoft Frontpage 2000, both from Windows98/NT workstations. The maintenance for them must be as easy as possible. At this moment their using a shared network drive (linux server with apache and samba installed). We're thinking of installing Zope and WebDAV for dynamic content. The main reason for using Zope is to get rid of the HTML-frames we are using now, and to maintain a uniform layout. In future we would like to personalise some pages and to add a webforum (Squishdot). Can anybody answer the following questions: * Has anybody implemented something like this before? Any pittfals I should watch out for? * Why is the default file index_html and not index.html (Windows doesn't want to open files without extensions). * Should I install 2.2.2. now, or are there any WebDav-updates in 2.2.4? * Is it possible to backup all files from Zope easily? (for example use a command-line webdav-client to pull everything out of the Zope database). I would like to have all the files backed up on a regular filesystem, rather than a proprietary database. Thanks, Regards, Pieter Biemond
