Sorry that I was mis-interpreting your question
Unfortunately I don't know what's wrong with your set-up. I can confirm that I cannot access your logbook with "konquerer", but can access it with "firefox". The "konquerer" (on Scientific Linux 5.7) just gets timed out.
But I can access other SSL/https ELOGs with the konquerer. The problem only occurs with your logbook!
Therefore I would think it is a particular problem of your installation. I have three ideas how to isolate the problem:
  • first, I would try to change to the standard port 443. Just in case it is related to some firewall, etc. problem.
  • second, I would try another operating system than Ubuntu Lucid. It should work of course with Ubuntu, but if it still doesn't work with the other operating system then many things are already ruled out.
  • third, I would try to set-up an apache webserver in front of ELOG. We have it here just for safety reasons. ELOG runs then on some special port and apache connects to it with a reverse proxy.
The latter is a little bit of work (about a day) if you never set-up apache before. Therefore I would try the other two, first.
Good luck!

thanks for the fast resonse.
1) port 433 done. No change
2) compiled elog 2.9.0 on Squeeze and only reused the config file. No change: https://daduke.org:8443/
3) we can do that (and we will) no problem, but I'd like to get it working w/o apache nonetheless
speaking of reverse proxy: we'd like to hook elog to our LDAP server. As there's no LDAP binding built in, is there any way to use apache LDAP auth and then bind to that one?[...]

Okay, I did run out of ideas. I've never tested Chrome, but IE 8 and konquerer works fine here with SSL for our logbooks, but not for your logbook.

Regarding LDAP: you'll either need to convince Stefan Ritt or do it yourself ;-) Stefan did last year a kerberos binding for me: I was lucky that many other people had already asked for the same thing before me.

ok thanks, I'll check the LDAP thing.

And just for the record: I have to conclude a clean install of elog 2.9.0 SSL does not work for half of the browsers out there on Debian Squeeze or Ubuntu Lucid right now. You might want to look into that.

 

thanks,

-Christian

If you want to use https you should know what a certificate is.
Certificates are used to encript the data, but at the same time they are used to identify the host.
ELOG is delivered with a self generated certificate.
This can be used to encript the data, but no certification authority knows this certificate, so nobody can guaratee that you are connected to the right host.
Most browsers will warn you, that nobody did and if you don't care you need to change the security settings of you browser to accept the connection anyway.

  67164   Wed Jan 25 10:07:16 2012 Warning Christian Herzogherzog@phys.ethz.chBug reportLinux2.9.0problems with https in Chrome and IE

 Hi,

 

we're evaluating elog right now at the Physics Department of ETH Zurich and I'm trying to come up with a good config. One of the first steps of course was to enable SSL/https. With http, all tested browsers work fine, but with https at least Google Chrome 16 and IE 9 do not get past the "unknown certificate" warning and I see "TCP connection broken" errors in the log file. Firefox however works fine. Same behavior on Linux, Mac and Windows (given the browser in question is available). elog server is running on Lucid.

Any idea?

 

thanks,

-Christian

After patching a windows 7 computer with MS12-006, can no longer connect to elog, get page cannot be displayed

See

http://support.microsoft.com/kb/2643584

 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?
