ZServer comes up fine, but IExplorer produces the intriguing error message when I try to connect: "Internet Explorer cannot open the Internet site http://localhost:9673/Main An Internal error occurred in the Windows Internet Extensions" I was puzzled by the fact that telnetting to port 9673 and doing a "GET /Main" or "GET /Main HTTP/1.1" produced the desired output, and after some further probing I've disabled "chunked encoding" as suggested in 'http_server.py'. Line 55: used_chunked = 0 (instead of 1) That seems to do the trick, everything works. ZServer currently seems to produce no stdout logging for HTTP, only for FTP connections. Is there a way to enable this? -- andre ---------------------------------------------- Andre Posumentov andre(a)babbage.co.uk ----------------------------------------------

- Suggestions for Zope 1.9.0
by Jose.Lacal＠icn.siemens.com 27 Jan '99

27 Jan '99

Disclaimer: I do not speak for my employer. They do not even support Linux. Not yet. Table of Contents. 1.- Overall impression. 2.- Positioning. 3.- Workspace improvements. 4.- Good to have. - - - - - 1.- Overall impression. a.) Awesome product! I am a Linux newbie, and the product is really nice. b.) The ocumentation (installation and initial configuration) *needs* to be improved from just a set of dysfunctional README.txt and WEBSERVER.txt files scattered all over the place. c.) For those interested, I have compiled a step-by-step set of instructions for installing Zope on a Linux box, along with the PyGreSQLDA. The file is available in PDF format. The document is still in draft form, but it's usable. - - - - - 2.- Positioning. a.) Zope's website states that: "Zope is a free, open source web application platform used for building high-performance, dynamic web sites." That definition, IMHO, is not even close to what Zope is. Plus, it is a very dry, unattractive Marketing one-liner. No offense intended, but it certainly looks like a site by nerds and for nerds. b.) It took me a week of playing with Zope (installed under both NT Server 4.0 and Red Hat Linux 5.2) and reading the manuals before I started to understand the magnitude of Zope's power. And I am still not done exploring its features. This is not a good thing for potential new users who are not hard-core techies. c.) I would suggest positioning Zope as a web-based, FrontPage-like web development environment that does NOT require the user / creator to have any software locally on his PC. Using Zope, anybody with access to a PC and the network (Intra / Internet) can publish their own website by using Zope's formatting / structural capabilities. "You focus on the art and the content, and Zope will handle all the nitty-gritty for you." Or something like that. Sell the sizzle, not the steak. People will not likely buy Zope because it's OpenSource, or because it's written in Python. Corporations will buy Zope because it allows non-programmer users to get their job done faster, cheaper, and with less hand-holding from the corporation's MIS / IT crowd. d.) Furthermore, Zope allows for the creation of web-enabled, database-driven applications from a web browser. That is, no more grudgery writing ODBC stuff and such. This product could find a serious following among the corporate crowd: techies define the ODBC links to the corporate databases, and then Joe Schmuck writes his / her own web-based queries to the databases using Zope, and then publishes the results to the corporate Intranet. e.) Yes, I _know_ most of the issues above are already discussed in Zope's website. If only after you go over the Zope Features, Questions and Answers, Zope Components, Zope Zen Revealed, and Testimonials sections. What I am saying is summarizing all of those benefits in one paragraph, maximum. f.) Web presence providers should love this product for their users. Using Zope to design and maintain a website is much better than using FrontPage and then dealing with the broken links and upload hassles! With Zope the user can backtrack when he deletes some portion of his site. With FrontPage, what's gone is gone. g.) I know, you guys tremble at the mention of comparing Zope with FrontPage. But, hey, in Marketing you need to consider the issue of educating your prospective customers. Instead of wasting time and resources educating the marketplace on what an "open source web application platform" is, why not piggyback on the widely known concept of what FrontPage is? The Bill has already spent millions of bucks promoting what a FrontPage-like app us supposed to do. So, let's take that and build a Zope definition on top of the pre-existing, widely-known FrontPage definition. h.) Buried on page 24 of the Principia manager's Guide we find the following text, which I suggest should be on Zope's main page: "Netscape Publishing Traditional websites often have multiple HTML files that use several different graphics files. For those based on the Netscape web browser version 3 or later, there exists a capability to publish a website from the content manager ’s desktop machine to the production website. This is advantageous for several reasons. First, since Netscape is the most common medium for browsing, content managers have standardized on Netscape for authoring. Next, the target market for Netscape’s authoring environment is the novice, thanks to its graphical presentation of web editing. Finally, Netscape conveniently lets you publish an entire directory of files, rather than one at a time. Since Principia also targets the content manager, it would make sense to let the content manager manage his content using Netscape authoring tools. This section describes how to use Netscape publishing with Principia." - - - - - 3.- Workspace improvements. a.) Add the size and date of last update for each file listed. b.) When in the "View" tab, there are no tabs on top. The user needs to hit the Back arrow. This is consufing and inconsistent with the rest of the tabs' functionality. - - - - - 4.- Good to have. a.) A full, Python-based HTML editor to create/edit HTML files via Zope. I think there are some options out there already. It's just a matter of integrating the code into Zope. One of those options is HTMLgen. Currently found at http://starship.skyport.net/lib.html this library of classes mirrors the HTML 3.2 markup elements. - - - - - That's all, folks.

- Unable to publish from Netscape Communicator 4.5

27 Jan '99

Background: - Running Zope 1.9.0 on a Red Hat Linux 5.2 server. - Using built-in web server (still unable to get Apache + Zope working on neither NT Server nor Linux). - Client PC runs Windoze 95. >From the client PC I try to publish to http://135.1.34.197:9673/Plutonia/News/ with User name: News_Admin Password: <verified> There is both a /Plutonia/News directory and an Admin user defined as News_Admin (according to the instructions on the Principia Manager's Guide. So, when I try to publish the file I get the following error message from Netscape: exceptions:AttributeError - Netscape Error uploading files The server responded: Sorry, an error occurred.

- ZServer
by Michel Pelletier 27 Jan '99

27 Jan '99

I noticed that when you FTP into ZServer it doesn't matter what userid or password you use, it allways says 'Login Successful'. Of course, your not authorized to see anything but your still logged in and there is still an open Medusa channel. Couldn't this be a hole into a possible Denial of Service attack? Michel

- ZServer reactions?
by Amos Latteier 27 Jan '99

27 Jan '99

Hello: I haven't heard any reactions so far to the new ZServer alpha release which includes FTP. I suppose that this is because it's so good that there are no bugs to report ;-) Seriously, I would love to hear from those who have taken the time to try it out. Did it work for you? Do you like the new FTP capabilities? Let us know. I'm very excited by the new server architecture, and want to know from you all what you think of it. Thanks! -Amos P.S. FYI, the next release of ZServer probably won't be out for a little bit, so now's a great time to make feature requests and submit bugs. The main new features of the next release will probably be major bug fixage, PCGI support, and possibly architecture and interface reorganizations.
