No, you can only edit this on the file level.

As always, Andreas has clever ideas. Never thought about this possibility.

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​.

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.

That's how it is implemented. If you use

Max email attachment size = 1000000

then attachments below 1 MB are sent as attachments, and if the attachment is above 1 MB, then only a link to the attachment in the elog is sent.

Wouldn't it make sense for ELog (by default) to still notify, but not send the attachments by e-mail if the size limit is reached?

Hi Jacky,
if I read the source code correctly then the maximum size of a base64 encoded email is hard coded to be 10 MB in elogd.h (recompile after changing it):
#define MAX_CONTENT_LENGTH 10*1024*1024
But I think that an 2.2 MB image should easily fit into that.

Hi,

I am doing an inline image that is about 2.2 MB.  When I do a submit, I got the following message:

Error sending Email via <i>"<email server>"</i>: Entry size too large for email notification.

May I know what is the limit of the entry size and how do I change it?  Thank you.

Jacky

This warning is triggered by the use of the sprintf() funciton, which can write beyond the boundary of the destination string. I replaced it by snprintf(), which should make the compiler happy. Code is committed. Unfortuantely I have no FC27 here, so if there is still some waring with the current code, please post the full warning list here.

Have you selected "HTML" encoding (below the main message box). The HTML editor is not activated if you have "plain" text encoding. Did you try the default elogd.cfg file? If you modified the config file and did a mistake there, the program can for example not properly find all directories. Also makse sure you did a full install with "make install", not just update the executable.

Hello everybody,

we had to setup a new server for our elog some time ago because the old one crashed. We are now running version ELOG V3.1.1-0767eb0.

In the previous installation we had these nice buttons for file upload, time stamp and equation editor, which are also available here in the online version.

I already found that in the installation directory ("/usr/local/elog/") there exists a directory "scripts" containing a file "ckeditor-config.js", which also contains the lines:
"config.extraPlugins = 'timestamp,dndfiles,eqneditor,fileupload';" and "{ name: 'insert', items: [ 'Image', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak', 'FileUpload', 'Timestamp', 'EqnEditor' ] },"

These plugins seem to be available in the subdirectory "scripts/ckeditor/plugins/". But why are they not loaded? Is it just a version issue? Or something else?

It would be nice to get a hint.

Best regards,

Roland
