  68629   Sat Jun 10 07:05:24 2017 Question Erkcan Ozcanerkcan@gmail.comBug reportLinuxV3.1.3-aded4aeServer dropping SSL connection while uploading large files

Hi,

I am having trouble with uploading large (>0.5MB) files to elog. We click on upload and in a couple of seconds, the webbrowser complains that the server has dropped the connection.

Following the suggestions I found on these forums (https://midas.psi.ch/elogs/Forum/66753), I increased the timeout.tv_sec to 30 in three locations in elogd.c, but this did not help.

The problem is present in my old elog installation (from ~2 years ago), as well as the latest git snapshot from bitbucket that I cloned on June 10, 2017.

PS: Upload seems to work for non-secure configuration. It still takes a while to load, but it completes. However we prefer to use secure connections ( SSL = 1 ).
PS: Using nmap I looked at the latency to the relevant port, it can be as high as 0.5sec, but most often it is shorter.

Cheers,
e.

Hi Erkcan,

I observed similar behaviours when attempting to do SSL uploads and mirroring over a WAN (see some of my recent posts).  Having not received any responses/help, and no time to try debugging the source myself, I've changed the way I use ELOG such that my attachment uploads are always local (on my Mac laptop, where I do most of my ELOGging) and I have switched off the mirroring, choosing instead to do my own rsync backup to a central linux server on which I have running a read-only ELOG executable.  This configuration is both relatively secure and stable, and it matches my use case well.  More generally, however, it is unfortunate that this SSL and mirroring functionality isn't truly there for all users, even though the documentation touts it to be so.

Best regards,

Andreas W.

One possibility is to run elog in non-SSL mode and put an Apache server in front of it. The Apache server can then do the SSL communication, and forward all requests to elog in plain text (non-SSL). This has been proven to work with large attachments, actually that's the way I use it.

I didn't find time to debug the SSL problem. If anybody is interested in doing so, the relevant code is in function server_loop() around line 30015 (SSL_read()).

Greetings,

Hi Stefan,

since recently (a few weeks) ELOG confuses the language translations.
Individual language strings are translated into garbage; most other strings are fine.
Currently I see the string "please select" translated into "ressed" (see attached picture), instead of what's written correctly in the language file "bitte auswählen".
But with every restart the corrupted strings vary: other strings are affected and other garbage strings are shown - some of them unreadable binary code (see Attachment 2).
I have the same version running in English: I see no problems there.
Kind regards

Andreas
