Hi there,

I have a connection problem with an actual elog installation. Many Browsers like as Chrome, Firefox and IE don't connect to the elog server with ssl = 1 in elogd.cfg.

I tested with Firefox 3.6 and IE 7 installations and there are no problems.

I guess it's a bug. Does someone have a suggestion to solve that problem?

Thx. Olaf

Hi!

This just started happening here also. Some users can't get on to a SSL=1 config'd elog using either IE or firefox 10 (win7 or linux) or chrome. SAFARI works. Occurs in 2.8.0 and a newly built (even after

ssl yum updates) 2.9.0 version on SL5.5 system. Seems to accept self signed cert then nothing.. (connection reset message). Tried an stunnel from one port to port running elog

with SSL=0. Same behavior. Doesn't work on some browsers. Any clues?

Thanks,

-John

Hi everyone,

it appears that many people have this problem. I believe this is simply a problem of your firewall settings. There are two simple checks you can do to test if I'm right or wrong:

Run your logbook on the standard port 443 and retry. If the special port has been opened on the firewall, it has been likely only opened for specific clients like firefox 3.6, IE 7, etc. If you use a different client (FF 10, IE 9) the port can be blocked.
Or just run the browser that does not work on the ELOG server. If it works to access ELOG via localhost, then you know for sure that it is the firewall.

I've actually tested it here at my institute: I've downloaded firefox 10 and could access ELOG on port 443 but couldn't access it on port 444, unless I've started FF10 on the ELOG host.

To John, Olaf and Christian: If you need to be able to use a special port and a certain set of browsers then just contact your computing division or whoever maintains your firewalls.

I hope this settles the matter.

Cheers

Andreas

Hi,

Thanks for the reply.

The elog server is running SL5.5 (updates applied). As you suggested, I ran firefox 3.6.26 on the elog server via https://localhost:port and it worked fine. Downloaded firefox 10.0.1 and retried

on elog server and get error again: The connection was Reset; The connection to the server was reset while the page was loading.

Hi,

One of our sys admins discovered that Firefox 10 appeared to send parts of the initial GET in two parts. As if there was a flush() after the "G" and this caused elog problems. By making the change in

the patch below, the read loop is re-entered again after the 2nd part of the GET comes in. Firefox 10.0.1 then works with ELOG with SSL. Stefan... perhaps you can take a look to see if there is a

better way to accomplish this?

One side effect with it done this way is that if you start a connection (ie, telnet localhost port) and type a single character, the elog will block further connections until the telnet is terminated.

Thank you,

-John Doroshenko

Yes, there is a new feature called record splitting which causes the browser to send the "G" of the "GET ..." in a dedicated TCP package. This started in FF10, Chrome 17, and it will come in others as well. It only affects direct SSL connections (SSL=1). I fixed the bug in SVN revision #2435. Please update also MXML to revision #73. Let's hope that surprises like that will not happen too often.

Thank you Stefan! I put up your new svn revision and we're back in business. Seems to be working perfectly.

And thank you again for your efforts with regards to ELOG. It is an incredibly handy tool.

Thanks,

Hi Scott,

yes, every user can export entries using the "find" command.

Just select the export format in the first line

Export to: CSV ("," separated) CSV (";" separated) XML Raw

I often use the XML Format, but CSV is fine if you just want to import the entries to some spreadsheet program.

I was shocked to find out that this feature has not yet made it into the documentation?!? But it is that simple to use that there is not much to document.

There is even an "Import" command, to reimport entries from a file. But this is tricky to use: if you have fields of type date or datetime, then you have to convert those fields in the proper format.

I tried EXPORTING logbooks as .csv but have not been fully successful. Elog seems to only export the data entered for various fields with the exception of the text field.

Here is an example export from my logbook (used to track simulator problems), I would like to also export the TEXT field so it can be used by my managers in excel...but as you can see there is no entry for "TEXT" fields...

Thanks in advance!

Yes, you're right: the text field is only exported in XML and Raw mode.

It is questionable how EXCEL should cope with HTML or ELCode output from the text fields.

But I admit that this would be a useful feature for logbooks that only use plain text entries. And it is simple to implement.

I've attached a patch to elogd.c from elog-2.9.2-2081 that adds a third CVS mode 'CSV (";" separated) + Text'.

(This string has not yet been added to the localization.)

As far as I've tested it works fine to import the text to OpenOffice and EXCEL, even with multiple text lines and HTML code in the text.

Of course the spreadsheet programs just display the HTML source.

Stefan, do you think this should be added to the official branch?
