I am moving from a Hyper-V host to a VMware host and created a new elog server. I installed the elog software and did an rsync to get the .cfg file and logbooks to the new server.

rsync -av root@old.elog.server:/usr/local/elog /usr/local/
 

On the new server all of the 2020 entries are missing and there does not appear to be a 2020 logbook on either server but I can still access the 2020 entries on the old server. Where might they be and how do I get them over to the new server.

Old server says version is ELOG V3.1.4-unknown and new server says version is ELOG V3.1.4-966e3dd

Bothe servers a fully updated CentOS 7.

Hi

Tested this using the 2.6.1 version which comes packed with ubuntu-dapper and a 2.7.5 version I've compiled from source.

If I compile the 2.7.5 version from source and start it using

sudo /usr/local/sbin/elogd -c /usr/local/elog/elogd.cfg

config snippets below

---------------------------------

/usr/local/elog/elogd.cfg:

[global]
port = 8080
;url = http://solsikker.dmi.dk/elog/

[demo]
Theme = default
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject
Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other
Options Category = General, Hardware, Software, Network, Other
Extendable Options = Category
Required Attributes = Author, Type
Page Title = ELOG - $subject
Reverse sort = 1
Quick filter = Date, Type
------------------------------------

The icons show up !!

If I go through an apache proxy (config snippets below)

----------------------------------------

/usr/local/elog/elogd.cfg:

[global]
port = 8080
url = http://solsikker.dmi.dk/elog/

[demo]
Theme = default
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject
Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other
Options Category = General, Hardware, Software, Network, Other
Extendable Options = Category
Required Attributes = Author, Type
Page Title = ELOG - $subject
Reverse sort = 1
Quick filter = Date, Type

From apache conf

ProxyPass /elog/ http://solsikker.dmi.dk:8080/
ProxyPassReverse /elog/ http://solsikker.dmi.dk:8080/
<Proxy *>
        Order deny,allow
        allow from all
</Proxy>
-------------------------------------

The icons are missing !!!

The icons a showing up when using apache and the 2.6.1 elog version.

Hello, dear ELOG's gurus.
Please help me to understand a problem with mirroring function.
It appears in ELOG V3.1.4-a04faf9f - the last official Windows release, as well as previous 3.1.3 Windows release, which I have checked for comparison.

When I'm using a manual configuration with "mirror server, cron, user" options for one (master) of two servers, it operates well, except the situation, when a new entry is submitted at the second (slave) server.
For example, for a new entry with a real ID#2 at Slave its logfile gives "NEW entry #0", so logfile of the master server gives "MIRROR: Error receiving message: Received wrong entry id "0"".
After that Master deletes this entry at Slave "MIRROR delete remote entry #2".

In case of mirror functions in both .cfg files (Master to Slave, Slave to Master) both servers hung on after the first mirror process.

Now let's imagine, what I want to do. 
Master, as a main-operation global log, is off-operation, Slave automatically becomes a reserv-operation local log with full information from Master due to previous periodic mirroring.
Users work with Slave, submit new entries - all with #0 ID.
After repairing Master starts active mirroring and just deletes all new entries from Slave.

It seems, that the problem is not with mirroring, but with a new entry ID, as was mentioned in https://elog.psi.ch/elogs/Forum/68850
Were these ID#0/mirror problems resolved somehow or may be it is not a problem, but simply my errors in ELOG configuration?
Is there a chance to get an up-to-date Windows-release with working both-sides mirror function and all other addings after V3.1.4-a04faf9f ?

Best regards,
Sergei

We have a number of temperature chambers – each has its own laptop running a local ELOG server, with unique logbook for each.  Using the mirror feature, these individual logbooks periodically synchronize to a single remote desktop server, which has a copy of each of the logbooks.  All of that works great, as long as each of the ELOG servers are storing the logbook(s) to their respective local hard drive.

I wanted the remote server to store its copy of the logbooks on the network file server.  I changed the global options of the elogd.cfg file, adding the following:

               Logbook dir = S:\SHARED\LOGBOOKS

That change worked fine on the remote desktop server – new logbook entries were now being stored on the network file server.

Unfortunately, I lost the ability to sync from the individual logbooks to the remote desktop server.  During synchronization, I now get the following error message: “Error sending local entry: Error transmitting message". 

Has anyone run into this? Does this make sense? Am I missing something? Is there a workaround? Is there a wrong time to drink beer?

Thanks,

Frank

Ich möchte meine "lokale" ELOG Installation mit einem Server in der Firma synchronisieren.

Dazu habe ich in der entfernten Firewall ein Portmapping auf den ELOG Server in der Firma eingerichtet.

Wenn ich von meiner "lokalen" Maschine im Browser  http://meinedomain.dyndns.xx:PORT aufrufe, kann ich auf den ELOG Server zugreifen.

Ich habe in meiner "lokalen" Installation in der Section [global] den Mirror-Server = http://meinedomain.dyndns.xx:PORT angeben.

Beim Synchornisieren bekomme ich jedoch den Hinweis "Fehler beim Zugriff auf entfertes Logbuch".......

In the emails generated by anyone making an entry in this log book, every apostrophe is followed by a semi-colon.  So the text "I don't think..."  appears in the email as "I don';t think...", and possibly that comment will appear in the email as "I don';;t think...." - not sure on the last bit.  It has been around in the past few versions of elog, but don't recall precisely when this started occurring.  It was fine back in February, with v2.9.2 (presumably) running.

Hi,

sorry for bugging you with this, but I could not find any information for making migration of elog system from one server to another.
The migration should be done from one server version (CentOS 6.10 to CentOS 7.6). Also we are talking about migration from one subdomain to another. Example subdomain1.example.com to subdomain2.example.com. Old elog application version is 3.1.2 and I would like to migrate to the latest version 3.1.4 

Is the migration from one system to another possible?  What are the prerequisites for migration?
Are there any instructions how to do it?

Thank you in advance and have yourself a lovely day,
Warmest regards
 

Hallo and thanks for a great program.

At my work we have previously been using another program (Rednotebook) for our lab journals, but now we wish to migrate to elog because it is more configurable and because it runs in a browser.

We would off course like to move all of our old log entries with us. Luckily Rednotebook uses a standard module (YAML) for data storage, so I can easily access the data (e.g. with python) and I have already done do, and I have exchanged the native markup with html.

Now I would prefer it if I can make the elog data files directly, in stead of using the elog command, because that makes it possible and easy to revert the change, and also to not have to handle escaping html string before feeding them to elog on the commandline. I have actually already written the program that produces the elog data files, but now I have a few questions:

1) Is there an overall way of validating the datafiles, to make sure elog doesn't choke on them at some point in the future when I try to open one of the old entries. Along the same lines, does elog parse all the files when the demon is started, so if it starts then I'm ok?

2) What exactly are the requirements for the HTML content

2a) Will any valid html do, or are there some speciel requirements (e.g. like &nbsp; at blank lines)

2b) Does it require a particular version of html, because then I could at least validate it against that doctype beforehand

3) Is there a log from elog where I can see if it encounters something it doesn't like?

I hope the you can answer some of my questions.

Regards Kenneth
