Hi Al; if I understand your situation correctly you want to access Elog db (logbooks) via another way. There are many ways depending on your knowledge, type of work needed, and ease of use. I have found that accessing whatever I need via Elog gui is satisfactory in many situations-- by simply exporting. THEN take the raw csv/xml  file and manipulte it more easily from there. There are MANY free web sites that will take your data then, and put it in still another format that you choose (usually manipulating the rows/columns to your liking or doing mail-merge type work on your data). BTW WPS (Windows Office clone) is awesome at further 'mail-merg'  techniques. THEN at that point you may have close to what you are trying to accomplish. I've also used PHP alot in this type of situation and have replicated Elog's data format for it's db (logbooks)..; so PHP is great in this maner, although of course it takes time to 'get-it-right' if you are not well versed in it. If you go into detail more of what type of format you want as the finalized product, maybe  more suggestions will be made.

Happy belated New Years everyone,

John

I can imagine some other Elog users have encounterd this too at some point so I'm wondering if there's a utilty or some way anyone knows of that I can use to parse a log file DIRECTLY to view the older data, without using the Elog GUI?

 

Hi John. The problem with using the Find-->Export method is that some of the Attributes for the older data are no longer shown on that screen because the Config file has since changed. That's why I'm contemplating somehow parsing the log files directly instead.

Well, you could put the old options back to the config file, do the export, then remove them again.

But have a look at the Elog database files ZZMMDDa.log in your logbook directory, they are pure ASCII files, which are relatively simple to parse.

Hi,

I had similar needs (access and parse logs ) so I'm  a small library in cpp. Have a look on https://github.com/flagarde/elogpp maybe it could be usefull for you too.

The command "Append on edit = " is getting executed everytime, when a dropdown menu is changed. This happens even at the first creation of an entry, so the append text stucks up multiple times in the text body.

I can confirm the issue also for "prepend on edit".
To be more precise, it gets executed everytime the condition state changes, if placed in the config without condition, or if placed in a condition, everytime the condition gets activated.

I have the same problem -- did you find a solution in using the nginx revese proxy with user login?

It does indeed seem to be a cookie stripping issue.  I just need to figure out how to get Nginx to forward these properly.

Thanks for the help.

Stefan Ritt wrote:

Actually this forum works through an Apache reverse proxy with authentication and it works, so I suspect that the problem has to do with jwilder/nginx-proxy. Since we don't have this here, all I can propose is that you do debugging yourself. Run elogd with the -v flag so that you see all requests coming from the user through the proxy. Compare the requests through Apache and Nginx to see if any argumets are stripped or mangled. Upon successful login, elog sets a cookie with a unique session-ID (the cookie name is "sid") to the browser. If you proxy strips that cookie, you would land on the login page. Maybe look in that direction.

Yes, I tried setting the URL parameter to the url used by the proxy.  It goes to the correct address but that landing is the login page.

Stefan Ritt wrote:

Have you tried the "URL = ..." statement? This determines you elog redirects if you log in. If you reach elog through a proxy, the URL is a different one that if you access it directly. In your case the proxy URL might be necessary.

I've been trying to configured a Synology NAS to run my personal elog with a reverse proxy to the outside world.  The best way seems to be running Elog in a Docker instance and then running a separate connected Docker running a nginx-proxy (in this case jwilder/nginx-proxy). This second container manages the certificates to letsencrypt and mapping URL requests to relevant containers so that connection is secured properly.  

It worked great in the initial test. However, I have an issue with authentication.  When I password protect the elog it goes to a login page.  When I give an correct password it loops back to the login page (incidentally when I give an incorrect password it gives an 'Invalid user name or password!' warning).  So I know that its getting the correct password but there is some issue that is resetting or ignoring the authentication.  I am never able to actually get to the protected content. 

Does anyone have any experience in using Nginx to setup a secure reverse proxy? Any insights into why this would mess with the authentication of elog?

 

Side note: I have tried using Apache to do the same and authentication worked fine.  But the pre-canned jwilder/nginx-proxy docker manages all the certificates automatically and seamlessly and allows me to have multiple services running on the same outward facing port on my router.  There is no equivalent (as far as I know) that uses Apache for proxying with letsencrypt​.

 

 

 

 

 

  69417   Sun Nov 21 23:20:15 2021 Question Harry Martinharrymartin772@gmail.comQuestionLinux3.1.2Body of new messages not getting saved when submitted

I've been using elog for a few years now.  I've had the current setup working for me up until today.  

If I create a new message (entry, whatever they are called), or if I attempt to update an existing message, only the header information is saved.  The body (the part I can see in the editor) does not get saved.

Yesterday, I did do some updates on the server machine.  Among them was an update to apache2, but I am not using apache2 (I can disable apache2, and elogd continues serving elog on client machines).  Also updated were several python3 packages; I ran into a compatibility problem with python3 with a different package, so I wonder if that could have some impact for elog also.  About 50 packages were updated altogether.

Hello Harry,

the elog server (elogd) is a standalone application written in C and contains a full webserver and logfile management system.
There are no other dependencies to apache or python.

You can use a webserver like apache or nginx in combination with elog to act as a proxy,
e.g. to handle the encryption part of the communication between your web browser and the elogd, but you don't need to.

Regarding the first part of your message:
The elog server worked normally; entries (including the text body) got saved correctly until the last update? 
The only thing in your list of updates, I can think of making this problem could be the update of ckeditor as it is the text editor used by elog.
The other packages should not be related to elog... but I am not a package maintainer.
I compiled elog from source and it brings the necessary files with it.

Best wishes,
Sebastian
