Hi,
I was wondering if anybody else seen this problem and maybe has a solution. I use Elog version 2.7.5 rev. 2172 that I compiled from the tar.gz package on a Ubuntu PC. It is very strange that everything works fine except I can not view / download PDF attachments specifically. I can view / download images and I can download all sorts of file formats: xls, doc, ppt, etc. Viewing in the same window / tab or in a different one does not work. Saving the attachment produces a file empty file with the correct name! This is so strange, for example following a link from an image or any other attachment type works but if that link is a PDF file I get an empty page! When uploading a PDF file there a thumbnails that are generated, I do view the thumbnail but not the PDF itself! I didn't even managed to start a download on PDF attachment.
Any help would be appreciated!

This sounds to me like you have a problem on your browser. I know that Acrobat Reader sometimes causes problems. The current version always crashes my broswer, so I cannot display PDFs inline, I rather have to same them, and the open them for display. Maybe you have a simlar problem. Since you see the PDF thumbnails, I believe that the PDF operations indise ELOG are ok. Can you view PDFs from other websites? Have you tried another browser? Maybe on another computer?

Hi,
Thanks for the reply. I just checked the access from two other computers and indeed it works. I tried to see what is the problem with my browser, I use Firefox 3.0.6 and tried to get a PDF from the web. So I do have the same problem with other sites for viewing a PDF, I mean when I click on a PDF link I get a white page and the browser does not invoke any plug-in or Acrobat Reader. But the major difference with Elog is that with other sites I can always right click on the link and do "Save as" and it starts the download and I get a valid file. With elog it does start the download but I get an empty file. Actually I checked inside and it is not really empty, it is a text file, here I attached an example (the content of the file when I tried to download a PDF from the Elog server):

The file you downloaded is actually the login screen of elog! So probably your login token expired between the display of the web page showing the attachemnt link and the attachment download, or you turned cookies off. So when you try to download the attachment, your user credentials are not passed as cookies together with that request and elog barks at you requiring a new login.

Hi,
OK but the box at login is checked to keep the login / password for 31 days and the cookies are enabled for sure. Now another user pointed out that it can not see pictures including the little icons when using Safari. I never used Safari but I got it just to see what is going on. So it took me some time but I think I have an idea now after comparing the source of a post that I read with Firefox to the one I get with Safari. Essentially the Firefox has the Javascript functions and class definitions before the HTML page starts. Very weird! Took me some time because when you view the source they both showed almost the same content (there are a few differences in <head>) ! But when I tried to save as HTML it showed this difference. Also I must mention that the problem for viewing the pdf attachments only happens with Firefox on Windows, I tried from a Linux PC and it works fine, now on Linux PC I have an older version of Firefox so maybe this has to do with Firefox version not OS. For this problem with the pictures and icons, if is not the Javascript related problem I am really totally last, how can one browser get the picture but not the other browser with the same content in the <body>!?! |

Hi Stefan,
I added a new logbook for test and posted a message with three attachments: picture file, PDF file and excel file. Could you log in and look if I did something obviously stupid? The link is:

User name: testUser
Password: go
I have this specific problem with the PDF attachments and I can not see any picture or the icons with Safari. Thanks a lot! |
Elog command line problem, posted by Razvan Gornea on Tue May 28 09:16:18 2013
|
I'm trying to use the command line to post automatically entries from a web based calendar. I run elogd behind SSL with user/pass configuration. I created an account for the calendar and used the following command line.
[gornea@lheppc63 ~]
$ elog -v -s -a Subject=Test -a Type=Notice -a Category=Planning -h svn.lhep.unibe.ch -p 443 -l "LHEP EXO General" -u calendar ******** "SORRY for SPAMMING! Testing automated posts from command line"
It seems like all parameters are OK but for some reason the connection gets closed. Anybody has an idea why? The SSL certificate is not valid and on the web page users have first to accept it. Can this explain the problem? Is there a flag for elog command line to instruct it to ignore SSL warnings? Thanks a lot!

Reverse sort, threaded display fails when there is only 1 entry in logbook, posted by Ravi Pappu on Sun Jul 14 15:15:19 2002
|
This is not a serious bug...but when the global settings are as follows
[global]
Display mode = threaded
Reverse sort = 1
all logbooks with only a single entry produce the wrong URL on
clicking "last 10"
The URL produced is http://localhost:8080/LogbookName/0
instead of http://localhost:8080/LogbookName/1

User/Admin privlege question, posted by Ralph Kuehn on Thu May 20 00:55:51 2004

Hello,
For some reason if I define a "login user" that is allowed the configure
option he is also allowed to change the configuration file. According to the
documentation it seems like this should NOT be the case. Any ideas as to
what the problem might be?
Thanks in advance for any help/advice.

Re: Only show log entries for logged-in user, posted by Ralph Kuehn on Wed Jun 30 14:59:06 2004

One way would be to create a seperate logbook for each student including the
teacher. It should then be fairly simple to set up the permissions however you
would like. For a large class it might be a bit cumbersome to set it up this way.

User groups, posted by Ralph Biggins on Sat Nov 5 15:21:44 2022

Is it possible to have within elog (defined in password file?) a user group so that only those members of a group have certain elements visible? |
