See

 A little more information here

We are running elog on an Ubuntu server

Elog was working fine, then, on a windows 7 machine, MS12-006 was installed, rebooted, and could no longer connect to the elog web page.

Discovered that in Internet Explorer 8, by unchecking the use TLS 1.0 in options advanced tab, and making sure that SSL 3.0, TLS 1.1, TLS 1.2 were checked, that the page once again worked.  I'm guessing the elog does not support SSL 3.0, otherwise, I assume I would have to uncheck that as well.  Things do appear to still work on XP, thus far, only Windows 7 appears to break.  While we have a work around, ideally we would like to see a bug fix so that (for legacy reasons), elog will still work with TLS 1.0 on Windows 7.

 

 Also, strangely, I am able to use the elog forum page https://midas.psi.ch/elogs/Forum while TLS 1.0 is checked.  I notice the version number is 2.9.0-2425, while we are using 2.9.0-2396, so wondering if this is fixed in this newer version.

The forum does not use TLS, but has Apache in front of it which works as a proxy. So TLS is actually handled by Apache, which might have a newer implementation of TLS. The ELOG version number certainly does not make a difference, I did not touch the SSL functionality in a while. But when you compile ELOG on your Ubunto server, you can maybe play with different versions of OpenSSL and see if that changes anything?

Hi there, I just compiled and installed elog on a machine running the newest Ubuntu server. Everything went fine - no problems. Running elog on it's own (no apache).  I moved over a bunch of logbooks from an older elog, which seemed to work. Now, elog seems to crash when people are uploading files. Here is a snip from my syslog, and you can see each time it crashes with "error 4."

I run elog as:

Usr = elog

Grp = elog

/usr/local/sbin/elog -p 8080 -c /usr/local/elog/elogd_exo.cfg -D

where elogd_exo is my config file. Nothing special in my config file.

 Another funny problem. When I'm uploading a file, the syslog says this:

Nothing odd in the logbooks, no real activity happening at the time of any crash. Crashes after any amount of time from 1 hour to 24 hours, with littleAny clues?

Ups. This bug must have lingered there since the beginning of time. Funny that nobody noticed in the last ten years or so. I have fixed it in the current git revision.

Thanks for the speedy fix.

FYI, our other Elog instances which are running ealrier versions do not exhibit this problem, as I confirmed that entering null ID/password returns "Invalid Username or password" as expected. This may be why it wasn't mentioned by anyone else before. Maybe something got inadvertently dropped in the newer version.

We also meet this issue occasionally, so how can we get rid of this?

No, We are using the released version 3.1.2

How to use the current git revision or is it a long time to wait for the next release?
