> is there an instruction document how to exacly host the ELOG on a server for example a raspberry pi?

would be same as on any other linux machine, in the nutshell:

- install generic raspbian (R-12 is current version)
- setup the network
- setup apache2 https with automatic https certificate renewal using certbot
- setup apache2 redirect to elogd port 8080
- setup elogd on port localhost:8080

some of this is written up here:
https://daq00.triumf.ca/DaqWiki/index.php/Ubuntu#Install_apache_httpd_proxy_for_midas_and_elog

in theory you can run elogd without apache https proxy, but I find computer security
people are quite happy when I tell them that I run apache https with SSLlabs score "A+".

also I believe elogd does not support automatic https certificate renewal, running
it behind apache https solves that.

another consideration, specifically for RaspberryPi, they use SD flash for storage,
and unlike SATA and NVMe SSDs, SD flash does not have SMART to report flash read,
write and wear-out problems. So you may run into unexpected SD flash failures. We do.

do daily/hourly rsync to backup/archive storage to avoid total data loss if this happens.

also be aware that SD flash is very slow, compared to normal PC SSDs. read speed is not too
bad, but write speed is quite abysmal.

as solution to this, RPi5 can have a PCIe/NVMe dongle, you can try that instead of SD flash.

K.O.

Will elog defer user identification and authorization to the ssl engine of a *local* Apache proxy?  I'd like to try elog in a site that requires the service port positively authenticate and identify users via smartcard certificate ID.  Per SOP they have Apache+mod_ssl setting SSLUserName=SSL_CLIENT_S_DN_CN which sets both the SSL request object's "user" field and the REMOTE_USER environment var relative to the mod_ssl's session's process group leader.  Users auth with Apache's mod_ssl as a single-signon replacement for web apps which have traditional native, internal user accounts/passwords, but those passwords are subsumed by the Apache/smartcard/mod_ssl setup.  The web apps define internal accounts matching the users' cert IDs but do not allow any management of the [unused] passwords.  Can elog do this?

 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

Well, it's definitely not a firewall problem. I tried it on hosts in different networks and of course in the same subnet as 
the elog server. As I wrote I tried it with different browsers on different OS and everywhere I had same issues if I used 
newer browsers. So I guess there are interoperability problems between elog and newer browsers.

And by the way if I change ssl = 1 to ssl = 0 there are no problems with any browsers.

But I want to use the ssl feature because security reasons.

Hope Stefan could locate and fix the problem.

Thx

 I'm having same issue. Kerberos is working on Apache on same ubuntu 12.04 server. I used the USE_KRB5 option for compiling elog.

Does anyone  have an idea to solve that problem? 

Hi, we are using ELOG for keeping track of a server maintainance.  I've
translated some of ELOG's strings.  The file is attached.  There will be
more translations, when I get inspired again ;-)

Thanks to Recai Oktas, who encourage me to complete the Bulgarian
translation for the Debian elog package, the Bulgarian translation is
completed and attached.

Hi Stefan,

Happy New Year!

I ran several searches thru the forum but I could not detect a suitable entry on the following:

Is it possible to hide/un-hide the Commands, like "Edit", "Reply", "Duplicate", from the Menu based upon an Option of an Attribute?

E.g. Attributes = Status, .. | Options Status = Open, Closed

When Status = "Open"; the Menu Commands "Edit", "Reply" and "Duplicate" are available.

When Status = "Closed"; the Menu Commands "Edit", "Reply" and "Duplicate" are hidden/not available.

-or-

Can this only be accomplished using 2 Logbooks (Open / Closed) and move an entry from "Open" to "Closed" where the Logbook "Closed" is not using the Commands  "Edit", "Reply", "Duplicate".

Kind regards,

Barend
