icon8.gif   System Error / Hangs with ELPG and threaded Msg's under Win 2k3 Server, posted by Ulrich Trüssel on Sat Feb 28 16:46:41 2004 Replay_Error_ELOG_auf_Wind_2k3_Server.jpg
Since I'n not a programmer I's like to be very carefulls with bug  
reports, but after testing for a while, I belive this my be a bug or  
something else:  
  
I have 2 systems running ELOG 2.5.1:   
1. uSE Linux 8.2, KDE 3.2 = NO problems at all! ELOG work's in every  
function quiet well!  
2. The Internet Server (of my friend): Windows 2003 Server, All MS paches  
installed, Running IIS 6.0 Port 80) and ELOG 2.5.1 (Port 8080) under  
FireDeamon 1.6GA (actual release) as a Service (Deamon).   
  
Problem under Win 2k3:  
This works very well, even with several users on the system and on ELOG  
as long as there is not msg. threaded! Is a Msg. Treaded ELOG produces  
the msg. showen in the attached Jepg-file below on Win 2k3.  
The problem occurs as soon as Elog would change to the threaded display 
or by clicking "Repaly" in the menu. Rights etc. are aleady checked on 
the file system and are looking well. Everithing will work well as 
nothing is thraded or testing locally under Linunx. 
 
Does anybody  
have an idea??? It my by a bog on Elog as well as from Microsoft or a  
problem produced by a dummy user (me...!). Since Linux don't have the  
problem and the same cfg-file and log-files are working well if I don't  
use mode=threaded as well as Display mode = threaded I believe it my be a  
realchance not to be the personal factor of the dummy user...   
  
ThankX for every hint!  
  
  
icon5.gif   Syntax for conditional list display, posted by Terry L on Tue Sep 15 18:04:35 2015 

Good Morning,

I would like to limit the ability to edit certain attributes in an ELOG logbook, depending on the user who is logged in.  I.e. if "guest" or a standard "login user" is logged in, I only want to allow the user to edit "attribute1" & "attribute2" of say, 5 attributes.  However, if an Admin user or specific user, say "Terry" or "Bob" is logged in, I want to allow ALL 5 attributes to be editable.  To expand on this, I may want to even limit the visibility of the attributes as well.

I've read though "Condition Attributes" section of the help page, but it is not clear to me how/if I can do this?  Is that section even relevant to what I want to accomplish?

Can anyone provide some guidance?

Thank you for your time & help!

Sincerely,

Terry

icon4.gif   Synchronizing mirror causes corruption of logbook entries with multiple logbooks defined?, posted by Glenn Horton-Smith on Fri Aug 27 23:11:45 2010 

We have been experiencing corruption of logbook entries by elogd mirror synchronization. Has anyone else encountered this? Is there a known cause and/or workaround for it?

Details

We have two elog servers set up with identical elogd.cfg and password files, except that one server has "Mirror server" pointing to the other host. There are three logbooks defined.  (Their names are DoubleChooz, BigBrotherTable, and FlushingTable.)  When the mirror synchronization happens, whether by "Mirror cron" or by an administrator hitting the "Synchronize all logbooks" link, it often happens that entries requiring synchronization are corrupted on both servers (not just the one to which the entry was copied). This is particularly likely to happen if entries have been made on both servers since the previous sync.

Looking at the logbook files themselves, we see that the corrupted entries will have attributes from the wrong logbooks. E.g., we'll see an empty "Barometer: " line in a DoubleChooz logbook file, where "Barometer" is an attribute that is only in the FlushingTable logbook, or we will see there are unexpected DoubleChooz logbook attributes in the FlushingTable files.

Strangely, the entries will not be identical on the two machines after syncing, and they stay non-identical on further syncs.

Most disturbingly, data is lost from entries that were perfectly valid before the sync, on both servers.

This was happening with elogd 2.7.8, and continued to happen after upgrading to 2.8.0. Both servers are running Linux. One is a 32-bit machine and another 64-bit, in case that might matter (but read on).

I made copies of both servers' files and ran two elogd servers on my Mac on different ports, compiled from a fresh checkout of 2.8.0, and the same behavior was observed as I repeatedly made test entries and synchronized.  This suggests it isn't specific to Linux architecture, 64-bit or otherwise.

 

icon5.gif   Synchronization using https, posted by Alexandre Lindote on Thu Jan 18 16:29:43 2007 
Hi,

I have an elog server running on a linux desktop machine inside our institutional firewall. It can be accessed from inside the firewall directly using http, but users from outside have to use https, with apache (and its ssl module) controlling the access.
I also set up another server on my laptop, just for backup purposes, and synchronized it inside the firewall (using a direct http connection). No problems there!
Now we want to have several servers set up (in different institutions), and have them synchronized automatically. For this I installed elog on a mac server (in another institution, so outside our firewall), also accessible only through https (again using apache).
I configured all the required mirror settings, but always get an error: "Remote server is not an ELOG server".
I've tried changing the status of the 2 machines (server-client), but get the same error...
I also tried different approaches for the Mirror server parameter, like
https://the.remote.server
https://the.remote.server:443
http://the.remote.server:443
but no luck...

Running elog with the -D flag off issued this message:

The servers have user level passwords, and I'm mirroring with Mirror user parameter set to the administrator...
Any ideas?

Thanks in advance

icon8.gif   Synchronization Problems, posted by Nicole Ackerman on Wed Sep 5 01:09:00 2007 
I'm currently running elog 2.6.5 on my (feisty ubuntu) laptop and desktop. I set up mirroring between the two which usually works, but occasionally I get an error (when sending from laptop to desktop) :

"Enty too long to display. Please increase TEXT_SIZE and recompile elogd."

When this happens my entry is shortened to 3 characters. This is frustrating as I have lost many important entries. I'm unsure why this is happening - they aren't the longest entries in my logbook (one was a one line linux command) and there doesn't seem to be anything "special" about the ones that do and do not sync. The last time I tried to sync I got this error on 3 entries and they appear to be corrupted - when I try to access them elogd stops responding.

On a presumably related note, every time I try to send an entry from my laptop to my desktop I get "Error sending local entry: Error transmitting message", though the entry has appeared to sync properly. I don't think I have ever had a problem transmitting from my desktop to my laptop.

Currently the only mirroring option I have added to my config file in on my laptop which is the IP of my desktop as the Mirror server.

I'm unsure what else I could post to help troubleshoot this problem - is it just something I've done wrong or that could be fixed with a reinstall?

Thanks!

icon5.gif   Synchronising between physically separate networks, posted by Dougie Mooney on Thu Jul 10 12:06:31 2008 

Hi there. Just started recently set up the application and think its very usable and easily configured - great stuff

I'm looking to roll it out to the masses but have a slight logistical problem in that we work on 2 separate networks - NET1 with connection to the internet, and NET2 physically isolated from NET1 and the internet.

It would be desirable to allow users to add/update/delete logs from both NET1 and NET2 with periodic synchronisation.

I believe the mirroring facility is what should be used, and think the following setup and synchronisation steps may be workable:

Setup:

  • elog installed on node of NET1
  • elog installed on 2 nodes of NET2
  • elog server running on NET1 and node1 of NET2 both using a common elogd.cfg

Performing Synchronisation:

  1. Stop the server on NET1
  2. copy logbook directories from NET1 to node2 of NET2
  3. start server on node2 of NET2 using the -M option
  4. once above complete, copy logbook directories from node 2 NET2 to NET1
  5. Start the server on NET1

Am I on the right track?

Would very much appreciate your comments and advice on the above.

Cheers Dougie

icon5.gif   Supress Email to Author of a message?, posted by Mike on Fri May 22 00:22:07 2009 

I couldn't find an obvious solution to the problem. I'd like to suppress email

notification to the author of a message. I've had some people complaining

that when they use elog they don't want to get an email about what they wrote

since they wrote it.


Is it possible?

 

Regards,

Mike

icon5.gif   Supress Email on Reply, posted by mike cianci on Wed Sep 9 08:16:22 2009 

The way I have ELOG configured it sends an email to supervisors based on which "Department " (attribute) was selected. Problem is that when the supervisor replies the department

is still selected and it sends a second email to the supervisor. Is there any way to supress the emails (automatically) on "Reply"?
