 | Andreas Warburton | awarburt@physics.mcgill.ca | Bug report | Linux | V3.1.3-aded4ae | Re: Server dropping SSL connection while uploading large files | 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.

Hi,
Could someone at least suggest how I could debug this problem myself? If I know where to start, perhaps I can fix it myself and contribute to the software.

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.

| Stefan Ritt | stefan.ritt@psi.ch | Bug report | Linux | V3.1.3-aded4ae | Re: Server dropping SSL connection while uploading large files | 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()).

 | Andreas Luedeke | andreas.luedeke@psi.ch | Request | All | V3.1.3-aded4ae | CSS reference in Email for private logbooks | We operate ELOG in an intranet. Many logbooks do send out emails; several use HTML content formatting.
If I watch HTML formatted emails from the intranet, then everything is fine.
If I try to read them from home, my email client hangs when it tries to read the CSS file from out intranet (URL: https://elog-gfa.psi.ch/SLS/elog.css).
Is there a way to set a URL for the email CSS?
Then I could simply copy the CSS file to the internet accessible location and the emails would be properly formatted in the intranet and from home.
I've tried to use "Use Email URL = ", but it turned out that this will change all base URL's in the email BUT the one in the CSS :-(
So I would need a config "Email CSS URL = " to set this.
Here is a patch that does what I want, but it might have some side-effects I'm not yet aware of:
7636,7643c7636,7638
< if (absolute_link) {
< if (lbs != NULL && getcfg(lbs->name, "Email CSS URL", str, sizeof(str)))
< strlcpy(css_base, str, sizeof(css_base));
< else if (lbs == NULL && getcfg("global", "Email CSS URL", str, sizeof(str)))
< strlcpy(css_base, str, sizeof(css_base));
< if (css_base[0] == 0)
< compose_base_url(lbs, css_base, sizeof(css_base), FALSE);
< } else
---
> if (absolute_link)
> compose_base_url(lbs, css_base, sizeof(css_base), FALSE);
> else

| Stefan Ritt | stefan.ritt@psi.ch | Request | All | V3.1.3-aded4ae | Re: CSS reference in Email for private logbooks | I changed the code ot include the CSS file directly in the email body. So no need any more for external CSS files. I dropped the "Email CSS URL" option as well.

| Devrim Esenturk | devrim.esenturk@gmail.com | Bug report | Linux | V3.1.3-7933898 | How many "Extendable options" can I add? | Hi
I am trying to add "Extendable options" for some attribute as below example. However button to add new item for list appears only for the first "Extendable options", if disable the first with (;), button appears for the second. It means elog add new item button only the first line "Extendable options" not for other?
Is this a limitation or bug or am I doing something wrong?
Options Require = N/A, Camera{1}, Lens{2}, Other{3}
{1} MOptions Require Model= XNB-6001, PNM-7000VD, PNM-9000VQ, PNM-9320VQ
{2} MOptions Require Lens = SLA-T2480, SLA-T2480V, SLA-T4680, SLA-T4680V, SLA-T1080F, SLA-2M2400P, SLA-2M2800P, SLA-2M3600P, SLA-2M6000P, SLA-2M1200P, SLA-5M3700P, SLA-5M4600P, SLA-5M7000P, SLA-2M2400Q, SLA-2M2800Q, SLA-2M3600Q, SLA-2M6000Q, SLA-5M3700Q, SLA-5M4600Q, SLA-5M7000Q, SLA-2M2400D, SLA-2M2800D, SLA-2M3600D, SLA-2M6000D

Your suggestion worked as it must be. I didn't see "Extendable options = <list>" on guide :/
I guess I need rest a little bit... :(
Thank you
Have a great weekend
