Stefan and friends,

without breaching your own security, could it be possible to see what the 
elogd.cfg file looks like, also if others would like to post theirs, this 
would be great in building exmaples etc, obviosly an security related or 
mail server entries hashed out.

I am a tad new at this stuff, but eventually would try my hand at getting 
hold of the source code and compiling on AIX and then intergrating into 
shell and error reporting. - OK .. a bit in the furture anyway, if someone 
has already done this please post.

kind regards Aamir

Dear Friends,

Anyone managed to compile elog on AIX 5.2 or 5.1 ... is there a binary 
anywhere?

new to "C"

kind regards Aamir

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

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

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?

Daniel Sajdyk wrote:

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

Stefan Ritt wrote:

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.

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>

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>
