Re: [Zope] Problem with ZSQLMethods/MySQL after update

2005-07-01 Thread Ragnar Beer
Thanks a lot for your help, Dieter, Greg, and Andy!

Dieter, you were absolutely right about the broken instances. All I had to
do was delete ZSQLMethods from my Products folder and restart Zope.
Everything was all right after that.

Andy and Greg, so far I did not have any problems using mysqlpython 1.2.0
with ZMySQLDA 2.0.8. But since Andy is the expert I now installed 2.0.9b3
and am happy with it.

:-) Cheers and thanks again,

Ragnar

[Zope] Problem with ZSQLMethods/MySQL after update

2005-06-27 Thread Ragnar Beer
Hi everybody!

After upgrading Zope from version 2.6.4 to 2.8.0 and mysqlpython from 0.9.2 to
1.2.0 I cannot add or edit ZSQLMethods anymore, although there is an open
(MySQL)db-Connection that works just fine with the same ZSQLMethods that cannot
be edited or with external methods. The error I'm getting is: 

There are no SQL database connections. You need to add a Zope SQL database
connection before you can edit a Zope SQL Method.

This happens only when using my old zope instance (which I need to) but not
when using a freshly created zope instance.

Is this a known problem? I couldn't find anything in my zope mailing list
archive.

Cheers, 

Ragnar

Re: [Zope] Zope on OpenBSD 2.8 problem solved

2001-01-31 Thread Ragnar Beer

Start Zope, and you will find that it works fine now. Zope also works fine
in the CURRENT tree of OpenBSD, so presumably it will work out-of-the-box on
OpenBSD 2.9. This is the safest way of getting it to work at the moment.

Did you understand form Jason Ish's message that it should be working 
with -current or did you compile and test it yourself? I compiled 
-current last week and it didn't work and there have been no changes 
to the source since then.

2001-01-31 Thread Ragnar Beer

What's the go4 book?

Ragnar

yes I have the go4 book and I fully agree that one or other of the above
patterns would be feasible. The problem is that the base medusa comes
from Sam Rushing and Zope makes use of it. I guess since I already patch
the Zope code I could just extend the patch, but the best solution would
come from having two main players agree on such stuff.

I just took his word for it:

  - python on this system uses /usr/lib/libc_r.so.3.3

  hmm, freaky.. works fine on my -current system.. I remember it being a
  bitch with Zope 2.2.4. well, the management interface works just fine

So if it doesn't work, somebody should notify the OpenBSD people. I
assume other Python applications than Zope have problems with this?

[Zope] Buffer overflow in MySQL 3.23.31

2001-01-23 Thread Ragnar Beer

Howdy!

Just for us MySQL users I'm forwarding this from bugtraq.

Ragnar

Hi,

all versions of MySQL  3.23.31 have a buffer-overflow which crashs the
server and which seems to be exploitable (ie. 4141414 in eip)

Problem :
An attacker could gain mysqld privileges (gaining access to all the
databases)

Requirements :
You need a valid login/password to exploit this

Solution :
Upgrade to 3.23.31

Proof-of-concept code :
None

Credits :

[Zope] Zope and Linux flavors

2001-01-16 Thread Ragnar Beer

Howdy Zopistas!

These days I came to the conclusion that I might need to investigate 
a bit on Linux as an alternative base for running Zope. So far I've 
been using OpenBSD which is a real timesaver when it comes to setting 
up a secure server which is my first priority over anything else.

What I'd like to know is:

Which Linux distributions are you using for running Zope and how easy 
it was for you to maximize security of your server?

Re: [Zope] OpenBSD 2.8 woes

2001-01-15 Thread Ragnar Beer

Seems you already found out what's wrong. Why didn't you post 
anything on the OBSD misc list so that they can fix it?

Ragnar


Hello Jan:

I don't really know what else I could do. Right now it looks
pretty much as if I'm going to switch to FreeBSD, my second
favourite :-| Has anyone got Zope 2.2.5 running under OpenBSD 
2.8??? If so, I'd
be really curious what steps you followed to get it to work.-

You will have to use FreeBSD or use OpenBSD 2.7.

2.8 will not work because there is a bug in the threading library 
included with OpenBSD 2.8. Zope triggers it when you call the 
management screen.

However, in the Zope code for the management screens there are 
"thread-safe" calls used which are not, as far as I know, used 
elsewhere in Zope. Maybe there is a bug in that code?

But for now I believe the bug to be in OpenBSD 2.8. I have not found 
anything to suggest that it has been fixed or looked at. None of the 
patches released so far for 2.8 mention it.

I went through this in early December.

Re: [Zope] OpenBSD 2.8 woes

2001-01-15 Thread Ragnar Beer

Whereas I couldn't reproduce the error in a prior thread this time I 
can. On my OBSD 2.8 machine running python 1.52 -with-thread CPU load 
goes up to 99% when I try to access the management screens. There was 
a discussion on the OBSD ports list to create a 1.52 port. Did you 
check whether there is and whether that's solving the problem?

Ragnar

Hello,


   Could anybody enlighten me??? I don't know Python (yet), so the
   tracebacks are not too informative for me ...

  Are you using Python 2.0?  It's not yet compatible with Zope, though
  efforts are being made. Just enter "python" to find out.


No, I'm not. At first I tried to take the version that comes
shipped as a package with OpenBSD 2.8, which is 1.6 with tk and
threads compiled in (at least that's what the package name
suggests).
When that didn't work, I pkg_deleted the package and then
downloaded the 1.52 as noted in the Zope specs, compiled and
installed it - it seemed to run, but Zope cr***ed out with a
python.core after trying to access the management screen. The
machine itself definitely is okay, techwise. The python
compilation and installation didn't show any errors. The OpenBSD
installation is totally virgin otherwise.

I don't really know what else I could do. Right now it looks
pretty much as if I'm going to switch to FreeBSD, my second
favourite :-|

RE: [Zope] Caching/http-acceleration and proxying Zope-served content

2001-01-09 Thread Ragnar Beer

I started using mod_proxy, because I needed the configuration options 
(redirection etc.) and squid wouldn't cache ssl stuff. It's running 
very well since about six months now.

The downside is that it's really badly documented. BTW there is a new 
book by Ralf Engelschall that you can download for free from 
http://www.apacheref.com that also covers mod_proxy. Not in detail 
though. He calls mod_proxy apache's stepchild.

Concerning numbers I gave some in my caching with mod_proxy howto 
(http://www.zope.org/Members/rbeer/caching).

Ragnar

Hmm.  That's been my thought on squid as well, given its ground-up design
for caching in the first place.  My worry, though, is that with squid I lose
support for virtual hosts on seperate boxes, because I need to support Zope,
static content, and some legacy stuff running ColdFusion on an NT box.  My
impression is that Squid's http accelerator mode (inverse transparent proxy,
or whatever you want to call it) is somewhat of an afterthought compared to
the standard proxy use case.  If it supports the ability to direct traffic
based upon the virtual host address, then squid works - if not, I think I
have to go the Apache route... I also wonder just how good Apache's
mod_proxy caching is?  Any thoughts?

  I have a question, for anyone experienced in working with Zope and caching
  proxies:

  I'm setting up a load-balanced server farm that has nodes that will run
  Apache and proxy (via mod_proxy) to ZEO clients running ZServer.  This
farm
  is routed (both ways) through a layer 4 load-balancing appliance, and all
  these boxes (both nodes and the balancer) are sitting inside a DMZ with
  private IP addresses.  The public world will access these servers via a
  firewall box running transparent proxy (actually, I guess, similar to
  squid's http_accel mode; the semantics here are a bit tricky, as it's more
  of a inverse trans-proxy).  Between Apache and Zope, there would be
several
  virtual hosts, and I'd be using the SiteAccess product.  It gets a bit
  tricky in that I need to access several different virtual hosts inside the
  DMZ (one for the ZEO farm, and another for a dedicated CGI-based ad server
  on another box) via the proxy.  A more detailed (ascii art) diagram of
what
  I am trying to do, is at http://209.132.8.98/server_ascii_art.txt

  My question is this: does anybody have any thoughts on the merits of Squid
  (http accelerator mode) versus Apache/mod_proxy in terms of caching,
virtual
  hosts, and the like when working with Zope sites?  Any big pitfalls to
this
  kind of setup with Zope sites?

I would prefer Squid since its only purpose in life is caching.  It
follows the "do one thing and do it well" mantra.

But whatever your choice, I hope you make use of the new CacheManagement
feature in Zope 2.3.  It is designed to make things like this
straightforward and easy.  There's a recent news announcement that links
to everything you need--including complete help docs!

[Zope] Re: running zope with OpenBSD 2.8 i386

2000-12-17 Thread Ragnar Beer

I still got it under construction. Zope shouldn't work with Python 
1.6 so I removed the package and downloaded the python 1.5.2 sources 
you ./configure --with-thread to have threads enabled and that's it. 
Runs beautifully but I didn't have time to install Zope so far. It's 
running very well under OBSD 2.7 but that version has a python 1.5.2 
package.

hi ..

I want to switch my webserver from linux 2.2.15 to OpenBSD 2.8. On the
linux machine I am running the zope webserver.
I tried to let it run with my OpenBSD home-installation, but it doesn't
work. It compiles slightly and starts up. When I connect to it it asks
me for the superuser account. Then I try to login but I get a lot of
error messages (python related, so maybe the port "python-1.6-threads"
is buggy?).

My question is: Did someone of you got zope running with obsd 2.8? The
documentation of zope says it runs in any case with 2.7 and python 1.6
...

(I tried the above on 2 machines, both obsd 2.8, both the same errors)


thanks for reading ...

2000-12-13 Thread Ragnar Beer

Howdy Zopistas!

Has anyone installed a Squishdot site with access restrictions? I've 
got the problem that as soon as I take away the "view" and "access 
contents information" permission from the anonymous user in my 
Squishdot site I cannot use the search interface anymore but only get 
KeyErrors (icon or thread_path depending on which permission I take 
away). I'm using Squishdot 0.7.2 and Zope 2.2.2.

Any help appreciated!

Ragnar

[Zope] Indirect addressing

2000-12-07 Thread Ragnar Beer

Howdy Zopistas!

I have a directory structure like this:

+ myfolder
index_html
my_external_method
dtml_method_1
dtml_method_2
...

In index_html I want to include either dtml_method_1 or 
dtml_method_2, ... (one method for every week of year). 
my_external_method tells me which dtml_method to include.
This would logically be handled with "dtml-var dtml-var 
my_external_method" in index_html but this doesn't work.

How could I get this working? Any ideas?

Re: [Zope] [ot] python book

2000-12-05 Thread Ragnar Beer

I read Learning Python and still love it and would highly recommend 
it. The book is very good! Apart from that I'm using the Python 
Essential Reference more often nowadays. It's handier than a printout 
of the lib.pdf but actually you don't really need if if you are comfy 
with the pdf stuff.

What I'm still missing is something like the perl cookbook but for Python :(

Ragnar

Hi,

I'm going through the tutorials available on Python.org but can anyone
recommend a good book?

I've always been impressed by O'Reilly's books and I see that there are
a number of them available:

- Python Programming on Win32
- Learning Python
- Programming Python

Which one of the above (or indeed, any others) would be best for me?
Me? I've got some C experience and will be using Python with Zope to
create a portal,  some simple apps.

Any advice would be greatly appreciated.

- Best regards,
Lee

[Zope] login dialog text

2000-11-30 Thread Ragnar Beer

Hi Zopistas!

When users connect to a restricted area a dialog box pops up that 
looks more or less like this:


Enter user name for Zope at myhost:
 User: _
Password: _


Where and how can I change the content of the first line so that it 
would e.g. read "Enter user name for funky stuff at myhost"?

you can put the following in your start script somewhere before the exec

[Zope] ZMySQL and MySQLdb Versions

2000-10-20 Thread Ragnar Beer

Howdy!

When I go to the download section on zope.org looking for a way to 
connect Zope and MySQL I can find the following:

- Zope MySQL Database Adapter, 2000/07/20 by mordred (ZMySQLDA-1.2.0.tar.gz)
- ZMySQLDA, 2000/07/20 by MikeP (ZMySQLDA-1.1.3-nonbin.tar.gz)
- An Interface for MySQL, 2000/07/20 by adustman (MySQLdb-0.1.2.tar.gz)

Now how should anybody new to Zope know what to use? Especially when 
ZMySQLDA goes up to at least version 2.0.0 (I tried to look it up but 
couldn't connect to starship.python.net) and MySQLdb at least to 
version 0.2.1. I'm still using ZMySQLDA 1.1.3 with MySQLdb 0.1.3 
which can't be found in the download section.

Confusing, isn't it? What could we possibly do about it?

Re: [Zope] IIS and Zope share same problem :-S

2000-10-20 Thread Ragnar Beer

As I already suggested ages ;) ago (and still didn't put into 
practice) it would here again be best to deny everything that isn't 
explicitly allowed (e.g. allow whatever ends with _html or .html and 
deny everything else) but then I would have to go over the whole 
website and make bazillions of changes ...

I fixed the problem temporarily by adding some 
"FilesMatch/LocationMatch + deny from all" in my httpd.conf. But what 
else do I have to deny apart from objectIds?

Yes, that old chestnut again. If it's considered a serious security flaw

solve it.

...and yes, there are discussions about this on Zope-dev right now,

[Zope] acl_users mystery

2000-09-06 Thread Ragnar Beer

Howdy!

I had a strange problem today: I added a Role "User" in the root's 
security tab and gave it a couple of permissions. But further down 
the tree in /de/support where in the acl_users folder I added a user 
with the role 'User' the permissions where not acquired (until set 
manually in the /de/support security tab I couldn't log in) although 
'Acquire permission settings' was turned on all the way down the 
tree. Very mysterious. Did I misunderstand the whole idea or is there 
something wrong? (Zope 2.1.6)

[Zope] Caching How-To (was Cache concerns (was zope/proxy_passconfiguration problem)configuration problem)

2000-08-04 Thread Ragnar Beer

During the last couple of days I could finally figure out how to set

going without my laptop so I won't answer any emails for the next two

Ragnar,

Caching is a subject I'm not all that familiar with but one I need to learn
really fast.  My site is about to go live, and I have a monster of a query
that will bring my system to its knees if 100 students run it at a time.  So
I'm sending this off to the Zope mailing list wondering if anyone can give
us some caching/performance tips.

Ragnar,

If you're referring to my ZServer+Apache+SSL HOWTO, this would be a
problem.
Going in through https will only give you access to the 'ssl' directory.
The quick  dirty solution (while retaining the ability to distinguish
between http and https) is to reverse the setup, i.e. place the https
SiteRoot in the main folder and create a separate folder called, say,
'http', which holds the http SiteRoot.  This solution will kill two birds
with one stone: it will grant access to the entire site via https while
restricting http users to an empty subdirectory.

Hope this helps,
T.J.

Re: [Zope] tree plus/minus url

2000-08-03 Thread Ragnar Beer

I found quite an easy solution for Zope 2.1.6:

In lib/python/TreeDisplay/TreeTag.py you have to replace the "old 
code" with the "new code". (Blame me - I forgot to make a copy 
beforehands which keeps me from using diff.)

The idea is to "export" the piece of code that puts together the url 
to treeData['tree-item-clickurl'] so that you can access it with 
dtml-var tree-item-clickurl within your tree-tag. I haven't checked 
this for unwanted side effects. Perhaps someone more familiar with 
the zope code could do that? For me it works fine!

[Zope] automatic link adjustment

2000-07-10 Thread Ragnar Beer

Howdy Zopistas out there!

I just ran into some kind of administrative problem: my students are 
not so willing anymore when it comes to changing links for the third 
revision of our website. There are about 200 links to change manually 
and they have my full sympathy. Apart from that this process is quite 
error-prone and always needs a lot of testing.

Is it possible to have automatic link adjustment in Zope if you 
change an objects name? I mean like in Dreamweaver or whatever 
website management programm so that it would ask whether to adjust 
the referring links if you change a page's name?

I know we could do the management partly with Dreamweaver and put the 
files via ftp but whatever sends cleartext passwords is not an 
option. So ftp is out.

Any other way?

[Zope] too many open files

2000-07-04 Thread Ragnar Beer

Help!

Zope 2.1.6 refuses to work in the middle of an external method on my 
i386 running under OpenBSD 2.7. Is says:

OSError
[Errno 24] Too many open files: '[EMAIL PROTECTED]'


I've never ever seen this problem before and this external method 
used to work well until some minutes ago. Now the error keeps 
reappearing even after rebooting and also other external methods that 
used to run well now deliver the same message.

Does anybody have suggestions how to diagnose/cure this problem?

Re: [Zope] Zope on OpenBSD

2000-06-16 Thread Ragnar Beer

Don't use the version from the ports tree.

That's absolutely right. Use the package instead! You can simply ftp 
the python-1.5.2 package from ftp.openbsd.org or one of its mirrors. 
This way it took me about 5 minutes to get Zope running from source 
under OpenBSD 2.6 on an i386. No need to build Python yourself:)

--Ragnar


Build and install Python yourself -- the ports tree that comes with the
OpenBSD 2.6 disk builds an older version of Python.

Then download, build and install your own copy of Zope from the source
version.

It's actually VERY EASY to build and install Zope from the source, I
recommend that everybody learn that method.

Re: [Zope] security issues

2000-06-04 Thread Ragnar Beer

   I will soon have a Zope-site ready to go online. How can I make shure
   that I did everything (concerning Zope) to stop intruders? Where can
   I find information about protecting a Zope-site? Has anyone had
   security problems so far?

Easiest (most brutal?) fix I've found - hide Zope behind an Apache,
and prohibit access to any URLs of the form .*/manage.*

This is what I'm doing at the moment (more or less) but your question 
made me think. Actually this is an example of "allow anything that 
isn't explicitly denied" which is not a very good policy if you want 
security. I remember (but - darn - can't remember where I have it) a 
posting that said that anyone can easily see the names of all objects 
in a folder which is nice intelligence gathering.
I guess it would be much better (and even more brutal;) to deny 
everything that isn't allowed explicitly. I'll try that later. I 
think I'll have to allow .*_html and .*_img for the http protocol 
plus all the .*/manage.* stuff for https and perhaps also make some 
(not so secure) restrictions based on ip adresses.
