Aha, that's interesting too! I'll have to look more carefully through the documentation... :)

You guys know that there is the possibility to execute an arbitrary script on each submission of a new messge? Just use "Execute new = <script>". In the script you have access to all parameters of the message. That's maybe simple than to watch the file set.

I just noticed that there are multiple messages per file, so I have to adapt the parser. I'll update this thread when I'm done!

Yeah, I suppose something like that would be both faster and more efficient than polling ELOG itself. Fortunately the ELOG disk format looks easily parsed.

Thanks for the pointer!

I recommend monitoring directly on the server. Here is an example of a very simply Python script (https://github.com/tamasgal/elog-slack) which monitors the files very efficiently and immediately pushes notifications to Slack (slack.com). Just look at the code, it's pretty straight forward and very easy to adapt it to other (web) services.

Btw. here is an ELOG entry of it https://midas.psi.ch/elogs/Forum/68224

Hi again!

I've another need that you probably already thought of :)

I'd like to be able to efficiently monitor a logbook for changes (new or edited posts) somehow. The most reasonable way I've found so far is to periodically poll a search that looks for posts after the time of the last poll. But that might note be very efficient, especially if the polling period gets short (or number of clients grows).

Is there some other feature that could be used for this? I was thinking maybe the ETag or Last-Modified HTTP header field could be used to show changes to a logbook by just reading the headers, but it would also require HEAD request support which does not seem to be there.

Cheers,

Johan

 

 

 

 

 

  73   Mon Jul 15 14:09:30 2002 Warning Joeri Mastopjoeri.mastop@knmi.nlBug report  Port specification with -p fails under RedHat Linux (2.0.4-1)
Hello,

I noticed a strange behaviour with Elog 2.0.4 (i386 RPM) in Linux (RH 7.2). 
I started Elog out-of-the-box with portnumber 888 ('sbin/elogd -p 888').

It runs just fine, but appears to listen to port 8080, the default! It 
looks like the -p option on the command-line is ignored.

Anyone seen similar problems? 

Joeri

> Anyone seen similar problems? 
Probably not if you read the config file, 'cause I didn't. Shame on me...

But what this shows (Stefan: correct me if I'm wrong) is that if you set 
the port number in the [global] section of the config file, the command-line
option '-p' is ignored. FYI...

I am having the same experience with ELOG 2.0.5 and Solaris 8. Any work 
around woud be appreciated.
  65726   Thu Feb 7 14:22:57 2008 Warning Jochen Krempelkrempel (at) ill.frBug reportAll2.7.2-2Absolut links for images in FCK Editor

We use ELOG inside a local network, but we want to allow access also from outside the firewall.

The suggested solution from Elog Admin Guide worked fine until version ELOG V2.6.5-1844 (essentially without FCK Editor):

ssh -L 1234:your.server.name:8080 your.firewall.name
firefox
http://localhost:1234/

Howerver, since the update to ELOG V2.7.1-2002 the FCK Editor uses absolute links to insert images.

An image uploaded from the local network will have an address like:

http://your.server.name:8080/logbookname/080207_101110/Picture.jpg

while the same image uploaded through the firewall tunnel will have a link like:

http://localhost:1234/logbookname/080207_101110/Picture.jpg

Obviously images uploaded from outside are not visible from inside and vice versa.

Is it possible to convince FCK Editor to use relative links?

PS
ELOG is great!!

I fixed this in SVN revision #2038.

Thank you for the quick support!

  65850   Wed Apr 23 18:59:30 2008 Idea Jochen Krempelkrempel(at)ill.frRequestAll2.7.3LaTeX support

I would appreciate if elog could provide a simple support for mathematical expressions.

A solution similar to wikimedia should be easy to implement and would help a lot.
http://www.mediawiki.org/wiki/Manual:Running_MediaWiki_on_Windows#Alternative_Solution

The idea is to parse the elog entry for a tag (e.g.  <math></math>), extract the code, wrap it into a latex file, and pass this to latex, GhostScript, and ImageMagic. (The latter are already used by Elog, therefore the changes should not be too big.) The resulting image file would then be referenced by the  elog html code.

Of course, the FCKeditor would not support LaTeX. However, the majority of elog-useres should be scientists and rather familiar with LaTeX. Therefore it should be fine if the original LaTeX code is saved (e.g. in the ALT-tag of the image) and the replacement "code to image" is undone for editing.

Kind regards,
Jochen

Hi Stefan - Do you know is Kerberos is available (compiled) on the Windows installer?

Kerberos support is not compiled into the binary RPM. You have to comile from sources to get that. The reason is that there are different Kerberos libraries around, and different people need different ones.
