Re: [Zope-dev] OpenSSH configuration between ZEO clients storage server
Eric Roby wrote: Anyone had any experience trying to secure the transactions between ZEO clients and a storage server??? Our shop is already using OpenSSH, I have read some introductory information about OpenSSH. It is just not clear to me the level of effort required to implement this or if implemented, will the additional overhead further exasperate the potential for unresolved conflict errors??? Any thoughts... Let's say you have a host called zeoclient and zeostorage. On zeostorage, start a ZEO server listening to some port, say 9673, making sure that it listens only on the *local* interface, usually 127.0.0.1. An example: python lib/python/ZEO/start.py -p 9673 -h 127.0.0.1 \ -S 1=/stores/fs:Storage Then on zeoclient you set up a tunnel: ssh -f -N -L 9673:zeostorage:9673 zeostorage Then your Zope install on zeoclient should use port 9673 on 127.0.0.1 to connect to the storage. In fact, the only piece of code that should know about the hostname zeostorage is the command to set up the SSH tunnel. There are some disadvantages: anybody who has an account on either zeoclient or zeostorage has full read/write access to the database. To avoid that, you'd need to use Unix domain sockets and come up with a way to forward one securely. Also, ssh is not 100% stable as a tunnel; I've seen ssh stop just because a forwarded connection disconnected unexpectedly. You might need to watch the ssh process and restart it if it dies. For zope.org there is a private subnet. The boxes each have two network cards AFAIK. All ZEO communication takes place on the private subnet. A VPN would also work, but you'd still have the local access issue.

[Zope-dev] FW: [Zope] Attaching multiple file to mime
I just tested dtml-boundary in the loop below and it fails.
Is this feature or bug?
Should dtml-boundary be altered to be a block-tag?

I dont see why nMIME is necessary?
I consider this a bug, unless someone can point out otherwise.
It should work the way below or Zope should be modified to work this way or
add an /dtml-boundary
dtml-in objectValues('File')
dtml-boundary type_expr=content_type disposition=attachment
encode=base64
filename_expr=_['sequence-item'].getId()
dtml-var sequence-item
/dtml-in
/dtml-mime
/dtml-sendmail

Subject: [Zope] Attaching multiple file to mime
hi to all,
some weeks ago Chris Bruce and me asked:
has anybody got any working example of how to send all of the files
in a folder as attachments using sendmail and mime?
This will not work with the original MIMETools. So I created a
new Product:
N(ew)MIMETools!
http://www.zope.org/Members/mjablonski/NMIMETools
With the NMIME-Product installed you can send all files of a folder for
example like this:
dtml-sendmail smtphost=127.0.0.1
To: [EMAIL PROTECTED]
From: [EMAIL PROTECTED]
Subject: NMIME-Example with multiple attachments
dtml-nmime type=text/plain encode=7bit
Just a demonstration how to send multiple attachments with
the NMIMETOOLS.
dtml-in objectValues('File')dtml-nboundary type_expr=content_type
disposition=attachment encode=base64
filename_expr=_['sequence-item'].getId()dtml-var
sequence-item/dtml-nboundary/dtml-in/dtml-nmime
/dtml-sendmail
Please note: the NMIMETools have the same arguments as the
original MIMETools.
The only difference: dtml-nboundary-tag is now a real-block-tag (with an
open close-statement) which allows iterating!
Maybe someone will find this helpful for his work. Bug reports
and comments
are welcome...
greetings, maik.

Re: [Zope-dev] Re: more on the segfault saga
Hello segfaulters and others interested in Zope instability issues! Our demi-god Matt Kromer from ZopeCorp has come up with a possible way to corner the instability issue AND give you a stable, cycle-garbage collecting Zope. Since the problem seems, so far, to be caused by the Python Restricted Compiler (which is used in everything from dtml expressions to python scripts to other stuff) not completing fully collectable objects before the Python cycle garbage collector finds them, the solution is to lock out the gc while creating these objects. The only easy way to do this currently is to disable the automatic gc and run manual garbage collections only when we're pretty sure no one else is running, and at the same time not letting anyone else run when we're running the gc. While I can't speak for Matt but since this is a fairly urgent matter, I believe he agrees that those experiencing segfaults are encouraged to replace Zope/ZServer/PubCore/ZServerPublisher.py with the attached file, which should work on 2.4.x and 2.5.x series Zopes, and report your instability results. This is the same file that can be found at: http://zope.org/Members/matt/ZServerPublisher.py with the difference that my version has some lines removed that are only interesting for those that applied Matt's cprof patches mentioned earlier on this list (which, I bet, means only me :-). The file is small enough so that you can manually look and see that I've installed no trojans in it :-) but those of a paranoid nature are encouraged to download Matt's version and remove the two lines that mention 'cprof'. We're close guys, very close. Cheers, Leo PS: standard disclaimers: I don't speak for anyone else but me and I won't be held responsible for anything you do to your site based on the aforementioned intructions.

[Zope-dev] Call Profiler strangeness - lots of ZODB transactions
I'm investigating why our product ZODB is growing when it shouldn't. I've found that the undo log has entries in it every five minutes saying Installed product CallProfiler by Zope. More infrequently (not regularly) we also have Installed product ZOracleDA by Zope. The Call Profiler was designed specifically not to hit the ZODB - it's in-memory only with. Our setup consists of seven ZEO clients talking to the one ZEO server - the one that's getting all these hits in the ZODB. Does anyone else see this happening? Anyone have any ideas why we're seeing this behaviour?
