We obtained a certificate from let's encrypt in order to replace the self signed certificate provided with elog. We copied the new certificates replacing the older server.crt

The problem is that when restarted elog raises an error related to the fact it is looking for server.crt and it doesn't find it anymore.

I searched in elog config file in order to find a way to indicate the new certificate but I didn't find how to manage this issue.

Any suggestion?

Hi Giuseppe,

The new certificate files should be copy under ssl folder (/usr/local/elog/ssl or /usr/share/elog/ssl by example, closed to templates and script directories) in place of the embedded (autosigned) certificate files enclosed with ELOG source.

It seems that there is no parameter to set a custom path.

SSL = <0 | 1>
Turn on Secure Socket Layer transport. If SSL is on, one can connect via https://... to the elogd daemon. If the URL = directive is used, make sure to use https://... instead of http://... there. The ELOG distribution contains a simple self-signed certificate in the ssl subdirectory. One can replace this certificate and key with a real ceritficate to avoid browser pop-up windows warning about the self-signed certificate. The default for this option is 0.

Hi Laurent,

thanks very much! Probably I've copied the certificate in the wrong directory. I'll try ASAP

Hi I'm here again,

According to my conf file I run elog under a specified user and group different from root. So I copied the .pem file I obtained from certbot in /etc/ssl as well as /urs/local/elog/ssl and ssl folder in the user directory (I will call it <user-dir>) but when I launch elog I receive the error that cannot initialize SSL because the old self signed certificate server.crt in <user-dir>/ssl is not found.

I wonder where in elog.cfg or elsewhere is written that <user-dir>/ssl/server.crt must be usedand how to fix it

Thanks

I do run elog under:

But that does not change the location of my certificates: they are in "/usr/local/elog/ssl".
My guess: you just copied the .pem file to the /ssl directory, but did not rename it to server.crt?
And of course you need to overwrite server.key as well.

Kind Regards
Andreas

Hi,

Is there a way to export the ELOG entries into a file like an Excel sheet or something.  I see import but not export.

Appreciate your help.

Thanks.

Illam

Find -> Export to...

Thanks Stefan for your help.  It works but the only issue is, the screenshots that were included in the body of the entries are not usable.  Not sure if there is any workarounds for that.

Hi,

I've just installed the news 3.1.5 version and I have 2 problems.
I don't know if it works with older versions because I started with latest.

- When using "select" menu then "edit" for multiple entries, the text is replaced with "- keep original text here -" instead of keeping the original values. Really annoying...

Another problem too, if I want to edit after, I have the error message "only author - keep original text here - can edit" although the author column is OK..
It looks like this problem is global and not only on text column.

- Version number is indicated "ELOG V3.1.4" instead of V3.1.5.

My config file :

I'm using Apache as reverse proxy with SSL and transparent Kerberos authentication (Microsoft Active Directory).
URL via Apache is https://elog.xxxxxx.xxx (no subdirectory).

Thanks for your help.

I checked and found that the bug which removed the main text was there since the beginning, but it's only triggered if you switch elog to French, it doesn't happen in the English version. I changed a bit the text processing so now it should work also in the French version.

I also changed the version number which is shown at the bottom to 3.1.5.

Stefan

Thanks for your prompt help.
It looks good for text but I still have problem with "select" function (even in English).

If I use "select" menu :
- When multiple values are selected it indicates "only user - keep original values - can edit" (freshly created).




- When a single value is selected, it indicates "only user XXX can edit" where XXX is my truncated name (the first 4 letters).



After editing in with admin account the author is now my truncated name :



If I want to edit a single entry (without select menu) it works perfectly.

Thanks.
 

If it works with a simple edit, then why don't you use that one to edit individual values. I checked and version 3.1.4 had already the same problem, so it was not newly introduced. I would have to invest a couple of hours to fix this issue correcly, which I simply don't have right now.

Thanks !

Sometime I need to edit multiple values to add a new choice.
By exemple, if I add a new column "status" (open, closed...) , it's mandatory to use select menu to add the new value to existent entries.

With a lot of lines it's not possible to edit one by one.

Hello,

I  tried to install Elog 3.1.4 from rpm on Oracle Linux 9 with command:

sudo dnf localinstall elog-3.1.4-3.el7.x86_64.rpm

But I got error:

Last metadata expiration check: 0:08:06 ago on Thu 02 Feb 2023 10:35:13 CET.
Error:
 Problem: conflicting requests
  - nothing provides libssl.so.10()(64bit) needed by elog-3.1.4-3.el7.x86_64
  - nothing provides libssl.so.10(libssl.so.10)(64bit) needed by elog-3.1.4-3.el7.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Using dnf I installed libssl.so.11 (cannot find version 10) and it doesn't help. So my question is: can I use one of proposes by dnf solution as:

1. --skip-broken
2. --nobest

Does Elog will work stabilityy after that?

Best Regards

Hi Daniel,

The RPM has been build for EL7 so SSL share libs should be different with the one provided by EL9. :-)

Try to rebuild from tarball source with enclosed buildrpm script (or with elog srpms if you find any : rpm -i elog*.src.rpm && vim ~/rpmbuild/SPEC/elog.spec # update build options as SSL/LDAP/PAM... && rpmbuild -bb ~/rpmbuild/SPEC/elog.spec ).

Gûd luck

I wanted to change some CKeditor settings so tried modifying elog/scripts/ckeditor to no avail.

I wiped elog/scripts/ and dropped a fresh download of CKeditor4, with only the basic extensions. But when I open the elog it still shows the full toolbar, with elog default style and with all extensions operational.

If I leave elog/scripts empty, I get "CKeditor NOT detected" when starting elogd and the HTML option is empty and shows nothing, all as expected.

Does anyone understand this? Is there some CKeditor configuration file elog is defering to that I've overlooked? I have tried system wide seaches just in case.

elogd checks for the "scripts/ckeditor/ckeditor.js" file to detect the presence of CKeditor.

So it was just a clearing cache issue. elogd was telling the browser to use/not use CKeditor based on the aformentioned, and browser was then using the cached version. Fixed now.

And FYI for anyone who reads this when trying to modify CKeditor themselves, it seems elog needs the iFrame Editing Area plugin included.

It means that you could replace the currently distributed CKeditor with a fresh vanilla installation of CKeditor? 

Yes replacing the CKeditor folder with a vanila download works without issue, provided you clean the cache.
For what I originally wanted to do (modifiying the toolbar) I could have just run elog/scripts/ckeditor/samples/toolbarconfigurator/index.html and edited the config file, but a clean cache is needed (on Chrome, Firefox and Edge).

I downloaded the last elog-3.1.5-1.tar.gz to install elog.

All *.cxx files are missing.

Hello,

I noticed the wikipedia article of the ELOG got deleted in November 2021.
With the reason: "Poorly sourced article, and I was not able to find good sources myself."

I could access the old article through web.archive.org, but for the project it would be good, if the article got revived.

I agree. I ahead ;-) I think it is not a good idea if the ELOG author pushes on that, but better someone else.

Best,
Stefan

It looks to me like only an author of an article can contradict a deletion. I did not find a single method to even comment on the deletion.
I am not an Wikipedia expert, can anyone suggest on how to push for the article to be restored? Or do we just write it again, until people stop deleting it?

I have requested an undeletion of the article. The article was deleted  "PROD", which means that someone tagged it. And if noone removes the tag, it could be deleted.

I could revive the article. So in the future, One should have an eye on it and maybe update the current version of the software.

If there iy an paper on the elog, maybe it could be cited for more creditability.

It was now moved to the Draft space (which I did not even now existed so far): https://en.wikipedia.org/wiki/Draft:ELOG

I added some more references, that's about all I can do. Not sure if that is enough.

Stefan

If I understand it correctly I think it has to be submitted for review with the blue button on that page, just not sure if that should come from your side or someone else

It appears to me that this is a really stupid problem: the article provides many links to sources, but they are just links, not "references". That does not count, since links could be something else than references.

I'll try to edit it and transform the list of external links into references to verify the text. Lets hope that this will suffice.

Okay: found three articles about applications of ELOG and put them under references. I took the liberty to submit the draft: it shows that they expect some month delay for a review. I have no idea if that was what they want, but it is worth a try.

I am rather with John on this.

I deliberately stopped contributing to Wikipedia years ago after I added an observation to an entry.  That is, a piece of what could be called original research.  It was shot down in flames for being precisely that: original research.    From what I read in the Draft:Elog and the Talk section,  I think that the same issue in some guise or other will come up.  All of us use and love Elog - I think I use it for all of the listed purposes - but apart from being in the Debian distro (which I did not know about) there is very little published primary sources.  Mind you, the quality of publications as primary sources can be questioned, I can bore on with several examples.  

Has anyone ever published a paper citing their filing cabinet organisation?  Elog's obviously different, but has the same problem when it comes to citations.  It is a utility, a very useful one, but the sort of utility that might just make an aside in a paper these days.  If we were in the 1980s and (hypothetically) Elog was available and as functional, that would probably make it the subject in computer research papers and magazines.

After fiddling around I managed to get ELOG working behind the load balancer HAProxy by stacking ELOG together with an Apache reverse proxy in a Docker stack. I am currently pretty convinced that something with the HTTP communication is somehow faulty in ELOG and Apache is more forgiving than HAProxy, since the configuration is the same as without Apache. So putting ELOG behind an Apache and then Apache behind the HAProxy is working.

For the sake of completeness, here is the HAProxy configuration:

backend be_elog.km3net.de
    mode http
    server-template km3net-elog- 1 km3net-elog_apache:80 check resolvers docker init-addr libc,none

Is this command line interface even able to communicate through a(n Apache) reverse proxy or does it need to communicate with elogd directly?
