Filter Menu text = scripts/calendar_filter/calendar_filter.html

The original theme is from Francois Cukier but I have change a some color 
and font.

Francois Cukier  said : "Uncompress "Bubble.zip" in your Elog default 
folder if you want to replace the original elog theme. Otherwise, if you 
decompress it in another folder, you will need to modify your elogd.cfg 
file as described at this adress: http://midas.psi.ch/elog/config.html"

Do it at the same ;o)

I want to thanks Francois Cukier and Stephan Ritt for their works, so 
THANKS a lot !

I wait your comments :o).


-UPDATE------------------------------------------------------------------------
2005/08/1 : Alexander Sheremet correct CSS bug thanks to it, archive re-uploaded

The following script creates a thumbnail for image/ps/pdf files.  
it can be used with "Execute edit" and "Execute new" configuration commands  
in order to get resized thumbs of attachments.  
  
It uses file(1), convert(1) for images, gs(1) is also required for ps and pdf.  
  
You have to start elogd with the "-x" option to enable execution and put  
something similar to the following in you configuration elog file:  
  
Execute new = /path/to/make_thumbs -s 650 -q 95 $attachments  
Execute edit = /path/to/make_thumbs -s 100 $attachments  
  
make_thumbs have to be executable by the user running elogd, of course.  
 
 
ChangeLog: 
* version 0.2.0 Fixes a BUG in PDF creation 

Everything in this guide was done on a full install of Fedora Core 3 running
Apache 2.0. If you are using an older version of Apache some of this may not
work, so I recommend upgrading. Also, on different Linux distributions, some
of the paths may be different.


The goal here is to get Elog set up under Secure Socket Layers, so that
communication both ways is encrypted.  This will cover any password
transactions so nothing gets sent over the web in the clear.

The previous method of securing the Elog, which involved using stunnel, is
out of date. A better way to go is to use the Elog in conjunction with
Apache. The Apache method leverages all the research and development that's
gone into providing secure sockets for Apache, and removes the need for any
serious reinventing of the wheel.


We begin with a web server running on port 80 and an Elog server running on
port 8080.


Making Certificates:
It's necessary to generate some secure certificates to be issued to anyone
who attempts to access the securesite.
A guide to making the certificates can be found at:

http://slacksite.com/apache/certificate.html

So, following the steps in the article:
   openssl genrsa -des3 -rand file1:file2:file3:file4:file5 -out\
   server.key 1024 
where the \ is merely an indicator that the command wouldn't fit on a line
here.  The fileN references are sources of random information to help the
random number seed be more random.  I merely used some personal text files
that were zipped up, as suggested in the page.

   openssl rsa -in server.key -out server.pem

Removes the RSA encryption from the key, to make it easier for the Apache
server to deal with it.

   openssl req -new -key server.key -out server.csr

Starts a line of questioning about us as a certificate issuing entity.
Answer with reasonable values.

  openssl x509 -req -days 60 -in server.csr -signkey server.key -  
  out\ 
  server.crt

After this move the server.pem, server.crt, and server.csr to the
appropriate directories under /etc/httpd/conf/ .  The extensions explain
which directory to put them in, with the exception that server.pem ended up
in etc/httpd/conf/ssl.key/ .


In the elogd.cfg file, change the port to 8079, and set the URL to
"https://your.host.name/" .  Restarting the Elog daemon now leaves us with
Elog listening to port 8079 instead of port 8080.


The rest of the story is in the "elogredirect.conf" file attached to this
post, but here are the highlights.

Create a virtual host dealing with SSL that listens to port 443 (the ssl
port), and acts as a proxy for port 8079 (where Elog is listening).  This
allows Apache to act as an SSL handler for Elog by handing off any access at
https://your.host.name/ to the Elog server.  The firewall then can keep out
any direct attempts to access port 8079, so that the only thing that can
reach the Elog server is stuff talking to 8079 on the local side of the
firewall (which pretty much means just the Apache proxy).  I recommend
Firestarter for the firewall config by the way, it's a real lifesaver.

http://firestarter.sourceforge.net/

This covers the SSL portion of the story, and by doing the redirection
inside the port 443 virtual host, instead of from the port 80 webpage as
before, you can avoid any path overlap.

As was the case for us, you may have links in older Elog posts, e-mails, or
web pages that point to specific Elog posts. If you have been using Elog for
some time and never bothered with the SSL stuff, the links most likely look
something like
http://your.host.name:8080/yourlogbook/postnumber. 

To cover legacy support for calls on port 8080, you can  create another
virtual host listening to port 8080.  This host's job is to take any
incoming URL calls on "http://your.host.name:8080/a_directory" and
translate them into calls on "https://your.host.name/the_same_directory" .
This means that any attempt to contact the Elog on port 8080 will get
answered by an Apache virtual host that redirects the client through the
Apache SSL virtual host described above. See the conf file for the details.

So in the end, the firewall is set to only allow through ports 80, 443, and
8080.  Port 80 handles the normal webpage access stuff.  Port 443
exclusively handles the SSL port for the Elog daemon, and port 8080
exclusively handles the redirect for the legacy Elog calls.

Implementation of this setup on another system should be pretty
straightforward.  Apache's config file is at /etc/httpd/conf/httpd.conf ,
and it also loads any *.conf files in /etc/httpd/conf.d/ .  So its a pretty
simple case of just dropping elogredirect.conf into /etc/httpd/conf.d/ and
restarting the Apache server.  Of course the necessary changes to elogd.cfg
have to be made and that server restarted as well.  The firewall, too, needs
to be setup to secure the whole deal. Note that the elogredirect.conf file
needs to be edited for your specific setup (changing the instances of 
"your.host.name" to whatever your server is, and also putting in the
administrator e-mail address where it is noted).


This work was done by Jonathan Hanson and Damon Nettles in the Gravity Lab
at Louisiana State University. You can see our Elog at
https://sam.phys.lsu.edu/elog .

If you have any questions or comments send them to
nettles@phgrav.phys.lsu.edu .

Takes one or more files from the command line that contain MIME
messages, and explodes their contents out into /tmp.  The parts
are sent to elog as attachments.

The elogd.init script that ships in the elog distribution is Linux centric.
 This script is written to work in a generic Unix environment under 'sh' -
no frills!

I have created a javascript to be used as a browser link that allows a one
step cut and paste from a web browser into a elog logbook. 

The intended application is allow a user to do a text selection in a web
browser, then click on a bookmark that automagically pastes the selected
text, the current browser page url, and the current browser page title into
a pre-defined elog logbook.   I do some research where I would like to save
some text from a webpage, but also have a record of where the webpage came
from.  However, you should find that you can extend this script in a varity
of ways for your own application.  

The script is a simple one: it uses javascript in a saved bookmark to get
your selected text, title, and url, and then creates a new browser window
with a elog form, and print the document variables into the form, and then
submits the form to elog.   The key advantage to this approach is that you
can use the "post" command, rather than "get", to submit to the text section
of an elog logbook.  The only way I found now to submit to elog via a
bookmark is using the "get" command, and it doesn't allow entry of the
"text" field, only attribute fields.    

The second major advantage to using POST is that you can submit a much 
large quanity of information ; However, some checking on this leads me to 
believe that the limit is browser and server depended, so YMMV.  However, a 
great discussion on the limits of browsers can be found here: 
http://www.squarefree.com/bookmarklets/browsers.html .

One of the major limits is that IE6.0 browsers have a maxium of 508 bytes
per bookmark - This book runs over 800 bytes, so I suspect tha IE6+ will 
not allow it. I tested the link with Mozilla and Firebird 0.7.

This script will need to edited for you to use with your elog logbook.
The script should be fairly self-explainitory, if you are used to html 
forms and have some exposure to javascript.

You will need to modifiy the following fields:

1) in form action = http://<your_domain.com>/elog/<logbook>/?cmd=New
   
   change the link to point to your specific logbook to be used for entry.

2) the attribute fields need match up with the ones in your logbook.

   The ones listed in the template are Author, Email, Title, and URL.

   If you have fixed fields (like Author and Email), then you can
   predefine these fields as shown.  

   I have the page title used as the entry for Title, and the page url is
   use as the URL attribute.

   Finally, I have the text selection used as the entry for the Text field.

   You can add additional fields by creating a new <input ...>  segment
   in the script.  For those more clever than me, you can concatinate the
   title, url and selection to paste into the Text area as well.  

3) once you have a edited version of the script (make sure you keep it as a
single line), you can then create a new bookmark in your browser, and then
paste the script into the properties->location field (for Mozilla/Firebird)
or the properites->url field (IE). Give it a good name like "post to elog"

4) once saved, you can then go a web page, select some text, and then go to
your bookmarks and click on the bookmark. It should then create a new
window in elog with a completed logbook entry.


some notes:

1) again, this may not work on IE6+ browsers due to M$ limitations.

2) You may have to be logged in already to elog for this work - I have not
tested the interaction using a password protected elog

3) You can only post to a single elog logbook - You'll need to have 
multiple bookmarks for multiple logbooks.

Note added by Stefan Ritt:

I zipped the attached JavaScript, since our email router does not allow .js 
file name extensions.

For all you guys (and girls;-) who want to add skins to ELOG, it is 
important to know what will be affected if you change a style.
So I made a cross reference of styles vs. html pages.

In the attached ZIP file you will find:
--> "ELOG CSS xref.xls" (Microsoft Excel spreadsheet)
--> "ELOG CSS xref.pdf" (PDF file for those who do not have Excel)
--> A directory containing the html pages I documented and the ELOG 
stylesheet (.css-file) that you need when you want to see the html files. 
Images are not included: they are not needed for this purpose.

I know that not all pages are documented, but Stefan told me that there is 
no complete list of all pages because they are generated. So I documented 
only the pages I need at this moment.

Please feel free to mail me when you have comments, corrections or 
additions.
