we know about certificates, thank you 
The point is that it stops AFTER the point at which I tell the browser to accept the self-signed certificates. I now even got a CACert and the problem remains: FF works, Chrome and IE don't: https://phd-bkp-gw2.ethz.ch:8080/admin/

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. [...]

[...]

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,

Excuse me, but I beg to differ. I'm running ELOG V2.9.0-2425 on my production server, therefore I thought that you're maybe right that the latest SVN snapshot has a problem.

I've downloaded it just now from SVN (it is V2.9.0- 2427), compiled it on SL 5.7, installed it and I can easily access it with IE8, Safari, konquerer and firefox.

 well maybe SL 5.7 is the explanation - it's old as the hills. Maybe newer versions of libssl or whatever make a difference? I might also try on a recent Fedora, let's see..

 

 update: clean install on F16, plain vanilla, same problem: TCP connection broken

See https://midas.psi.ch/elogs/Forum/67184 to fix that problem. It is likely not a problem of ELOG, but of your firewall settings.

see #67184, I'm pretty positive it isn't.

 Hi,

I have the same problem. with SSL = 1 in elog.cfg I am not able to connect using firefox 10 or chrome. However, using Internet explorer 6.0 it works fine.

Everything it has been checked in a local machine with windows 7 with and without firewall. 

Use port 443, works fine with all browser.

Thank you so much!

Finally I was able to reproduce the problem. I don't know why FF10 worked locally on the ELOG host last weekend, maybe I shouldn't have worked on it during a night shift. I can now confirm that ELOG has problems with firefox 10.0.1.

For those who need a quick workaround: you can set-up apache to access elog via a reverse proxy (like I do and like Stefan does for the ELOG forum does). That 'll work fine with new browsers like FF10.0.1 (at least for apache 2.2) ;-)

Some guidance how to set it up can be found here: https://midas.psi.ch/elogs/Contributions/11

A shorter (but may be incomplete) summary:

  • add in httpd.conf
    • Listen 443
      LoadModule proxy_module modules/mod_proxy.so
    • ServerName <fully-qualified-host-name>
    •  
  • add in ssl.conf
    • <VirtualHost _default_:443>

ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel warn
SSLEngine on
SSLProxyEngine on
ProxyPreserveHost On
<Location />
    ProxyPass         https://<fully-qualified-host-name>:444/
    ProxyPassReverse  https://<fully-qualified-host-name>:444/
    SSLRequireSSL
</Location>
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW
SSLProxyCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLCertificateFile "<cert-file>"
SSLCertificateKeyFile "<cert-key-file>"
</VirtualHost> 

  • And in the ELOG configuration [global] section
    •  port = 444
    • URL = https://<fully-qualified-host-name>                 

Cheers

Andreas

 With Chrome 17 there is the same problem. 

Is not possible a quick workaround for windows 7 users that we do not use apache server?

Thank you so much!!

I answer myself... Modify the value of width=100% in the class .listtitle2 in the .css file.

Hi all

I am trying to send email via Gmail smtp with no success. Elog uses port 25 which is not allowed. I need to use 587 or 465 ports to send mail. How can I change the port?

Have a good year all!
