I have a setting which makes ELOG a perfect solution, but there's a situation that I'm struggling to get my head around. We have 3 separate laboratories, each one containing a number of temperature chambers, which run almost constantly over a number of shifts. Each temperature chamber has it's own logbook (laptop). So far, pretty simple.
My dilemma is, our network goes down for maintenance/updates (more often than I'd like), but our operation cannot afford to stop during network interruptions.
With that said, I thought about whether I could run a "local" logbook on each laptop/chamber, and somehow mirror the local logbook to the main ELOG server.
Perhaps I'm over-thinking this...do you have any recommendations?

Sure that's easy. Install elog on each laptop separately, so they run without network. Then, set up a central elog server, and use "mirroring" as explained in the documentation at https://elog.psi.ch/elog/config.html#mirroring

So when ever the entwork comes back, you execute a manual mirror operation, and your new entries will be pushed to the central elog server.

Best,
Stefan

Thanks Stephan! I guess I was making it harder than it is.  I'm still a little fuzzy -- in this instance, am I correct in saying that each laptop would be considered a "master", and the remote (network) server considered the "slave"?  Also, I'm not sure quite sure -- which server should be assigned responsibility for performing periodic synchronization between the laptop and the central elog server?

Thanks again for all you do -- Happy Holidays!

Frank

I would call the laptops the "master" being responsible for pushing data to the central server which you can call "slave"

Stefan

Thank you again -- very much appreciated!

I've got things working - sort of.  Ran into one strange problem that has me scratching my head.  I have two different laptops, each running a local instance of their own logbook.  Both are functional, but for some strange reason, one looks great, and the other is missing its graphic format.  I've attached a screen capture of that logbook, and a copy of the config file.  Do you see something that I've done wrong?

Thanks,

Frank

Sorry -- dumb mistake.  I moved the "theme" files to the resource folder.  Works like a champ...life is good!

When there are attachments in an entry, logbook is adding additional "MIME-Version" header to e-mail messages.

Spam filter in our university system is mostly giving warnings:

• X-Amavis-Alert: BAD HEADER SECTION, Duplicate header field: "MIME-Version"

But sometimes it is not redirecting further the message.

• Remote Server returned '< #5.6.0 smtp; 554 5.6.0 Bounce, id=27666-07 - BAD HEADER>'

In code I noticed there is always "MIME-Version" header added to the message and additionaly it is added again when a file is attached. I think it is not neccessary to add again this header.

I just checked the current installatin, and just found one MIME-Version in the header, even with attachments:

MIME-Version: 1.0
--------------717E3059287C82F12BC14941
Content-Type: multipart/related;
  boundary="------------4543EB0E5AAC14B461D70512"

No idea where your second header comes from, but sometimes I have seen some SPAM filters adding things to headers.

Hello,

Is it possible to remove the "active" checkbox a user sees when they click on "config"?  Alternatively, is it possible to have a new user arrive directly at the logbook they chose, rather than starting out at the config screen?

We are running elog-3.1.1 on SL6 with webserver authentication.  For the most part this works great, but somehow a few users become inactive after they login for the first time.  They claim they didn't un-check "active," but I can't think of any other way this would happen.

Many thanks,
Devin

Hi,
  I reopen this old thread since I'm having a similar problem.

I'm running ELOG V3.1.1-0767eb0 on ubuntu with webserver authentication, and I'd like to remove 'active' checkbox as well.

The problem that we found is that if any user click on the [Set None] button at the bottom of the Config page in order to unsubscribe from all mail notification, *all* the checkbox are toggled, not only those for the email notification. And this includes 
also the "active user" as well.
Moreover, if an user click directly on the "active user" checkbox, a warning dialog box appears, asking for confirmation, but this is not the case is [Set none] is pressed: so, in that case, a user deactivate itself without warning.

Looking at the web page as well as at the code, I did not find a possibility, but maybe someone knows better.

Thanks in advance,
  Stefano

I can confirm that this bug is present even in this forum and in my current version (ELOG V3.1.3-aded4ae).
And I am positive that this is a bug: it was certainly not the intended behaviour.

Hi,
  a possible solution is to change the current SetAll() and SetNone() javascript functions to something like:


  <!--
function SetNone()
{
  for(var i=0,els=document.querySelectorAll('[name^="sub_lb"]'); i<els.length; i++)
  {
    els[i].checked = false;
  }
}
function SetAll()
{
  for(var i=0,els=document.querySelectorAll('[name^="sub_lb"]'); i<els.length; i++)
  {
    els[i].checked = true;
  }
}
//-->

It works on Chromium 58.x and Firefox 53.x, I don't know about other browsers.

The javascript snippet is generated in function elogd.c: void show_config_page(LOGBOOK * lbs) (line 13960-984 on my version of the source code).

Best,
  Stefano

Hi,
  sorry to bother again on this issue, but it is causing me some trouble, as many of my users are using the "SetNone" button in their config page, and doing so they deactivate their account, which I have to 
re-activate manually.

The warning about "Are you sure you want to deactivate your own account ..." is actually triggered only when someone toggle the "active" radio button, but not when the "SetNone" function is used. In that 
case no warning is present, and the user just deactivate his/her account. I'm sure that this is not the intended behavior.

I attach a modified version of elogd.c (based on git c1866af75bb2fe62aa868c4cf562f43a08e4b499 ) with the modified javascript I proposed earlier in this thread.

best,
  Stefano

Thanks for the fix, I merged it into the current development branch.

Stefan

I changed the code ot include the CSS file directly in the email body. So no need any more for external CSS files. I dropped the "Email CSS URL" option as well.

Dear ELOG experts,

the ELOG server on our lab crashes  continuosly, when we add a new entry or even if we click the arrows to navigate between entries. Following the FAQ on the website, I have used gdb and found the following error:

xmalloc: not enough memory

[Inferior 1 (process 23271) exited with code 01]

It should be then some allocation issue when we try to access to the entries, but I could not figure the nature of the issue. I was, however, able to reproduce it with a fresh ELOG installation and the same configuration file (ELOG cloned from git and installed today)

Could you please give me any suggestion? I attach here the configuration file we use.

Best regards,

Antonio Iuliano

I tried to reproduce the problem but could not. The config file uses "emtpy.html", "filtermenutext.html" and so on which I don't have. Same with eventlocation.

Rather than sending me all the files, can you strip down your elogd.cfg to a minimal version where you still see the problem. Then give me all information to reproduce it. You also have to tell me when the error occurs, like when you submit a new entry, scan through entries etc.

Stefan

Hi,

When i set Language = French in global config it works in french until i logout, after i can't login anymore, even if i enter my user and password i always stay at the login window, the only way to login again is to edit the Elogd.cfg file in Elog directory, remove the Language = french and save then i can login in and work normally in english version.

Thanks.

I just tried myself with the current version 3.1.4 and it worked for me flawlessly. Maybe you want to upgrade.

Stefan

I Stefan, i got the problem again with the french version, i realised that if i open it with Chrome or Edge it's not working but with Internet Explorer it works envery times. Is there a way i can use it with Chrome?

Thanks!

Have you tried to delete all cookies in Chrome?

Stefan

I've deleted the cookies and it works.

Thanks!

Hi,

We've made changes in our network and now we have to use port 587 instead of port 25, how can i edit that parameter?

Thanks

This is nicely explained in the documentation: https://elog.psi.ch/elog/config.html#global

I believe Yanick means the SMTP port, not the port under which elogd is listening. The SMPT port is hard wired to 25, because port 587 was not yet defiend when I wrote that code. I can make this a variable, but only if it works. So Yanick can you test if port 587 accepts normal SMTP commands? We don't have such a new server at our lab and I cannot test it. Under Windows you can open a command prompt and telnet to the mail server:

telnet <server> 587
HELO test
MAIL FROM: test

your server should then reply with "220 ..." and "250 ..." messages. Once this works, I will implement the variable SMTP port.

Stefan

I Stefan, it works with the 587 port.

Ok, so I added the option 

STMP port = xxx

where you can specify 587 to override the default port 25. I committed the changes to bitbucket. Can you compile from sources, or do I have to dig out my dusty Windows PC?

Stefan

Good! 

so, i've tried to compile but iwonder if i does it correctly,

look at the error i got:

Thanks again!

I put a new executable for you under https://elog.psi.ch/elog/download/windows/

It's named elog314-2.exe

Best,
Stefan

Hello, 

now we kwow it's working are you gonne send us a version with the SMTP port editable?

Thanks!
