ELOG Forum

I'm trying to install elog in our webserver and it's becoming a boring task. First of all theres only RPM packages. And we really don't like the Red Hat method, so we use Debian Servers. More package mainteners would be nice.

The software appears to be working correctly, but there are some bugs (or perhaps missing dependencies?); the init script put in /etc/rc.d/init.d is broken under Debian:

First of all because it's in /etc/rc.d.

The second problem is in this line:

# Source function library.

#. /etc/rc.d/init.d/functions

The file doesn't even exists.

The third problem is the echo_success; echo_failure commands that doesn't even exist. As I can see it's definitions are sourced in the functions file that doesn't exist.

After removing this missing commands or files from the init.d; I can call elogd script and start the daemon under root. Appears to be working...

And last but not least; there's a way to standardize the init script to run in other Linux distros, so we can put it to start automatically at boot time?

Many thanks in advance,

Vinícius Ferrão

PS: I'm not asking to support any creepy distros, but to support the .deb package format and system style.

/etc/rc.d/init.d/functions is part of the initscripts.rpm - so only usable on RedHat/CentOS..

Can someone also update https://midas.psi.ch/elog/download.html ? It was last updated in 2001 and the download directory contains a debian package that was last updated 2004. If debian is not supported in a current version that bit should be removed from the page.

Kind regards,
Achim

Can I ask for some clarification; I would like to include code highlighting for some computational students who will be making use of ELOG.

In the example you showed, my understanding is that you included a "Bottom text =... " entry in the forums elog config. This included the bare minimum remote call outlined by the highlightjs site. Can you clarify (as I'm having issues setting it up) should the "Bottom text=..." entry take this as a string, or should it be contained in a seperate html file in the same local directory as the cfg?

Ok. Thanks a lot :)

Stefan Ritt wrote:

In the HTML editor, you can select the code text, then select from the "Styles" drop-down the style "Computer Code", and on the "Normal" drop-down the formatting "Formatted". This puts the code in <pre> and <code> tags, so you don't have to manipulate HTML directly.

Daniel Sajdyk wrote:

Looks like it works :)

Code need to be put in tags:

<pre><code class="sql">...</code></pre>

but it works.

Thank you :D

I did not know about highlight.js . You can put it into any elog page with "Bottom text = ...". I tried it for this forum and put in some C code:

#include <stdio.h>
int main()
{
   // printf() displays the string inside quotation
   printf("C Programming");
   return 0;
}

Seems like this works nicely. Thanks for that hint.

Daniel Sajdyk wrote:

I thought so.

One more question :) I want manually add that parser (https://highlightjs.org), but I'm newby in that and don't know where ....

I know that downloaded hightlight pack I must put into folder scripts, but where to add this line:

<script>hljs.initHighlightingOnLoad();</script>

You can manually highlight code, but there is no automatic language parser.

Is there any way to highlight code (for example php, SQL) in elogs entries?

Thanks for the quicky reply Stefan. Yes, I had inut the same string! My error was not restarting the server; I've done this and code highlighting works fine.

Stefan Ritt wrote:

All I did was this:

Bottom Text = <link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.6.0/styles/default.min.css"><script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/9.6.0/highlight.min.js"></script><script>hljs.initHighlightingOnLoad();</script>

Problem with CRYPT+SSL and elog command line entries

I am in the process of setting up a new ELOG logbook. I checked out rev2280 from svn.savannah.psi.ch. I knew I wanted to encrypt passwords, so when I compiled, I used flags

USE_SSL=1

and

USE_CRYPT=1

I am running Red Hat enterprise linux 3, glibc-devel-2.3.2-95.50, openssl-devel-0.9.7a-33.25

Everything seemed to be working fine--I was able to set up logbooks using both a password file as well as write passwords and make entries to the logs. Then I tried to use the command line 'elog' to make an entry which failed to both logbooks.

/opt/elog/pro/elogd -c /opt/elog/pro/dansce_fancy.cfg -l Demo1 -w <mypassword>

Would change the password in dansce_fancy.cfg and I could make entries through the web interface, but

elog -h acouture -s -p 8081 -w <mypassword> -l Demo1 -a Author="Aaron Couture" -a Type=Routine -m Sampleinfo.txt -x -n 1

failed with

Error: Invalid user name or password

I got the same behaviour when I used a logbook with a user/password pair defined in a password file.

When I looked at the output from running elogd with the -v flag, I could see that everything was being received on the server side, but that the password did not agree with the write password in dansce_fancy.cfg

I then recompiled elog with

USE_SSL=1

USE_CRYPT=

And then the elog command line entries worked, both with write passwords and a password file (after recreating the password file and the write password). Looking at the elog.c source code, it appears that it does not know to use crypt rather then base64_encode when USE_CRYPT is true. elogd.c defined different behaviour if USE_CRYPT is defined.

Thanks,

Aaron Couture

Re: Problem with CRYPT+SSL and elog command line entries

I Aaron Couture wrote:

I have attached a possible patch--basically pirated from elogd.c Because strlcpy needed for the crypt cares about size, do_crypt needed the size, which had not been a concern for base64_encode in elog.c As a result, base64_encode changed slightly as well. I think the implementation places a limit of 32 characters on passwords, which seemed to already be the limit in elogd.c The elog.c limit appeared to be 80 characters. I tested both SSL and SSL+CRYPT for commandline elog entries with both a logbook specific write password as well as username/password combo in a password file.

There was some sloppiness in the original patch--__USE_XOPEN wasn't defined, but worked when elog wasn't compiled alone. Now the appropriate ifndef/define statements are in elog.c
