Count me for another one who is nowhere near "where" he can use

Please, *please*, don't! What is the point of posting links to
screenshots (with the additional hassle for you to create and upload
them and for us to switch media to see them) when (i) it is not
necessary, (ii) being them about some pure text item it would be
easier and more communication-friendly to just paste it here directly?
I suggest you to go to DOS console's properties and enable fast
editing mode. Then dragging the mouse with left button pressed will
select, pressing return copy and right-clicking paste. This makes its
c&p somewhat more starnixish, although I still can't make sense of the
additional key required in the middle. M$teries! Another slight
difference is that it is rectangle basis, which is also annoying
sometimes.
Back to Perl -but not too much, really- your screenshot shows your
attempts to call a script. Note that you can do so with any of the
following:
perl script.pl [arguments]
script.pl [arguments]
In the former the extension need not be .pl and the latter assumes
that .pl has been associated with Perl, which ActivePerl's
installation automatically does - and I'm 99% confident you're using
AP. If you additionally add .pl to the %PATHEXT% env variable (which
AP's installation does *not* do), then you would be able to call the
script without specifying its extension. That is, if you have
script.pl you could also call it like
script [arguments]
Last, and on a very x 10 OT basis (already waiting for Ben to bash
me!) I seem to notice a "spurious" line on the left side of your last
screenshot. This suggests me that you're grabbin the whole screen with
PrtSc and cropping it with some image editing program - one more
reason to be astonished by your byzantine way of proceeding. But you
can just grab the window of a specific app in the first place, by
putting it in foreground and pressing Alt-PrtSc instead.
HTH,
Michele

An entirely different problem. Since the OS cannot do it, the
webserver takes care of doing it. In that case it *does* want the
correct path.

Apache on Windows does not require the correct path in the shebang
line, as long as apache is configured "correctly".
Uncomment the following line in the httpd.conf file and it will use
the registry instead of the shebang line to find Perl.
ScriptInterpreterSource registry
Once that is "activated", you can use the exact same shebang line as
you use on *nix.

In addition to "activating" that line in the conf file, you could also
make a registry entry that assures that Perl will run all .cgi scripts
(without having to have a file type association) and will run in taint
mode.
Create and execute a cgi.reg file with the following:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.cgi]
[HKEY_CLASSES_ROOT\.cgi\Shell]
[HKEY_CLASSES_ROOT\.cgi\Shell\ExecCGI]
[HKEY_CLASSES_ROOT\.cgi\Shell\ExecCGI\Command]
@="C:\\Perl\\bin\\perl.exe -T"

Thank you for the correction. Of course I didn't know and was just
guessing instead.

The characters are separated by nulls. The file is in UTF16LE format;

Thank you Charlton.
No, the one I've seen are not those. For example, I've tried MyBlog from
http://www.fuzzymonkey.net/software/blog/. So, it seems I have to visit
your list.
Do you know about a commented directory on this subject (blog script in
Perl) ? What are the advantages and drawbacks of the 3 (or 4) you
indicate me ?

You might want to try AngerWhale [http://www.angerwhale.org/] for an
interesting approach at blogging software. Jonathan Rockway's site
[http://www.jrocks.us] has some good slides on the software.
And of course you can also try slashcode [http://www.slashcode.com/,
http://sourceforge.net/projects/slashcode/] which as you can probably
guess from the name is the software running slashdot [http://
www.slashdot.org]

I've seen the name you gave me :
- Er : don't know where to find it !
- LiveJournal at http://www.livejournal.com/ : it seems to be a blog
host, not a software to install on your own cgi-bin space.
- MovableType : http://www.movabletype.com/download/personal-use.html :
it's effectively a Perl script using a SQL database, but don't know
really yet why they ask for PHP (they say for "dynamic publishing", but
I've not read the detail at this time).
- Blosxom : http://www.blosxom.com/ : also a Perl script, lightweight
and open-source, and it doesn't need any database server. I don't know
if it accepts image upload ?!
So, I have to look deeper MovableType and Blosxom (and Er maybe), but
here is the list of feature I wish :
- Upload of text and image
- Permalink
- RSS feed
- Archives navigation
- Searching
- List of links toward articles containing the most recent comments
And, without use of any external database could be a plus for my case.

Thank you, Robert. I've added them to my list *TO_TEST*.
So, actually, my list is this one (from Charlton post too) :
- MovableType
- Blosxom
- AngerWhale
- slashcode
At your opinion, what's the easier (about install and configuration) to
build a blog with these features ? :
- Ability to fine tune the theme (at least, colors and fonts)
- Easy web admin board (to post, edit, delete, etc)
- Text posting (and ability to edit it in case of mistake)
- Image uploading (will appear as zoomable thumbnail in post)
- Permalink (to display both one post and its comments in one page)
- RSS feed (to allow syndication)
- Archives navigation (through category or date)
- Searching (word based with eventual OR/AND logic)
- List of links toward articles containing the most recent comments
- Ability to work in an iframe (don't know what it will do about iframe
height ; does it will resize automatically)
- Not any need of external database server (MySQL, etc) ; I hesitate on
this point.
And it would be a plus if :
- Choice of a category
- Comment posting w/o subscription, but saving coordinates in a cookie
- Good comment preview
- Unicode support (to accept chars like 'euro' or capitals w/ accent)
- Plugin oriented (just in case a feature doesn't exist)
- Possibility to bann a user, IP or domain
- Good errors management (I mean toward user wiyh explicit message)
- Sending of every post toward its author (and me through BCC)

I've worked around the problem by switching from XML::LibXML to
XML::SAX::PurePerl as the underlying parser -- now, the string
read in from the configuration file no longer has the UTF8 flag
set, and the problem does not appear.
I still think it's a bug that a string that can successfully opendir()
a directory, combined (including the appropriate separator) with a
file name read in by readdir(), does not result in a string that can
by used to open() or stat() the file. Especially since the path appears
correct when printed as part of an error message, and it's difficult
to diagnose the problem without resorting to something like Devel::Peek.
Thanks for the assistance,
Gary Ansok

What exploits are you referring to and which of those do you believe

So, you want to run a perl script, but you don't want it to run Perl.
That doesn't make any sense.
How is a person that is just viewing your website going to arbitrarily
run Perl? They will only be able to run the cgi scripts that you
allow. So, it sounds like the real vulnerability may be with your
poorly written cgi scripts.

Setting the FTYPE, ASSOC, and PATH ENV are merely conveniences.
Removing them will not fix any real or perceived vulnerabilities.
