icon5.gif   Restrict edit time = 0 behavior intended?, posted by Chris Körner on Mon Nov 15 11:35:55 2021 

Hi,

I have set the options "Restrict edit time = 24" and "Admin restrict edit time = 0" in [global]. This way can only edit entries for 24 hours while the admin can forever. I now want a single logbook where all users have unlimited time to edit entries. However, setting "Restrict edit time = 0" in this specific logbook behaves differently to the admin setting as it simply sets the time to 0. Is this behavior intended or a bug? I guess a workaround is to specify the edit limitation not in global but in all logbooks seperately.

Actually this is related to post 68993 from Sebastian Schenk in Jul 2019. Are there any new workarounds I may have missed?

Hi Chris,

my old entry was related to the admin options of edit time.
The option "Admin restrict edit time" was implemented later, see ab8b98c

As a workaround you should be able to give "Restrict edit time" a ridiculous high number in the specific logbook, which should overwrite the global.
In the documentation is no rule specified for diabling global settings for specific logbooks, as far as i know.

Best wishes,
Sebastian

Hi Sebastian,

thanks for the reply. It is just a bit confusing that these similar settings behave so differently. For me it is no big deal to set the time for every logbook independently instead of [global], but it leaves more room for configuration errors.

Best,
Chris

icon3.gif   Shared logbook and elog.cfg file across multiple installations, posted by Anthony on Mon Nov 15 15:41:04 2021 

Hi,

I'm wondering if it's possible to have a shared logbook and elog.cfg between multiple instances of elog.  Ideally, I'd like to have my logbooks folder and elog.cfg hosted on a nextcloud instance while running the elog service locally.  I've tried this using symlinks and shortcuts on windows with no luck.  I was able to install elog into my mounted nextcloud folder, but this isn't ideal as I would like this to work from multiple computers.

Any ideas or thoughts on how I can do this (if I can actually do this)?

    icon2.gif   Re: Shared logbook and elog.cfg file across multiple installations, posted by Sebastian Schenk on Mon Nov 15 17:40:08 2021 

Hi Anthony,

the elog has a mirroring function, which synchornizes config and logs between multiple instances.
See the bottom section of https://elog.psi.ch/elog/config.html

Best wishes,
Sebastian

Thank you Sebastian!

I admittidely haven't looked through the page in a while, so I completely missed this feature.  This should solve the problem, although in a slightly different implementation than what I was trying for.

icon5.gif   results of security scan, posted by David Stops on Mon Nov 1 12:52:23 2021 

Recently central IT scanned our elog server and reported the following "vulnerabilities"

  • 42873 (1) - SSL Medium Strength Cipher Suites Supported (SWEET32)
  • 51192 (1) - SSL Certificate Cannot Be Trusted
  • 65821 (1) - SSL RC4 Cipher Suites Supported (Bar Mitzvah)
  • 85582 (1) - Web Application Potentially Vulnerable to Clickjacking

Is there any easy way of preventing these

The elgod.c progarm itself is rather weak in SSL, since I just don't have time to catch up with the latest SSL enhancements. The safest you can do is to put an industry-strenth web server like Apache in front of elogd and let that server handle the SSL layer.

icon5.gif   While mirroring, data fields not preserved, posted by Rob Calkins on Tue Oct 26 01:21:01 2021 

While running two e-log books that were mirrored, I ended up with the situation of two entries with the same number/id.  The mirroring did what it said it would, increment the local logbook entry and grab the entry from the remote logbook. However, when it did, it did not preserve the fields in the log book that are specified in the config file such as "Author", "Priority", "Subject" ect.  I ended up with a very minimal log:

icon5.gif   Too many open files - issue?, posted by Rob Calkins on Fri Oct 15 23:57:38 2021 

Has anyone had issues with having too many files open? I'll setup my server and let it go but after a while, I end up with a lot of "cannot create socket: Too many open files" errors being reported.  I have a sync to another e-log going which I suspect is part of the cause since that e-log server hasn't had this issue. I suspect that there are files being opened, going into some return loop code and then never getting closed. I'm not a C programmer but I see lines like :

fh = open(tmp_filename, O_RDONLY);
      if (fh > 0) {
         read(fh, result, size - 1);
         close(fh);
      }

      /* remove temporary file */
      remove(tmp_filename);

This looks like it opens the file but unless the remove function closes the file, it will remain open even through the file has been deleted. Maybe this isn't the correct behaviour of 'remove' and I am mistaken?

There are also parts like :

 fh = open(textfile, O_RDONLY | O_BINARY);
      if (fh < 0) {
         printf("Message file \"%s\" does not exist.\n", textfile);
         return 1;
      }

      size = (INT) lseek(fh, 0, SEEK_END);
      lseek(fh, 0, SEEK_SET);

      if (size > (INT) (sizeof(text) - 1)) {
         printf("Message file \"%s\" is too long (%zd bytes max).\n", textfile, sizeof(text));
         return 1;
      }

This looks like for the second error, it will complain that the file is too long, return an error message but not close the file and would leave it open. Is this a reasonable avenue to pursue or am I mis-reading the code?   Thanks.

    icon2.gif   Re: Too many open files - issue?, posted by Stefan Ritt on Mon Oct 25 13:34:06 2021 

The code segements you show are from the command line tool elog.c, not the server elogd.c. The tool is called to submit a new message from the command line. Even if there would be a file not properly closed, it will be closed by the operating system once the program finishes. So no problem of too many open files there.

icon5.gif   Display last page by default, posted by Yoshio Imai on Fri Oct 28 12:15:33 2005 
Hi again!
I have one question concerning the logbook configuration. Normally, clicking on "List" takes me to the first page of the list view. Is it possible to configure the logbook so that "List" takes me to the last page instead?

Thanks for the quick reply. Unfortunately, this is not exactly what we need. We would like to see the entries in normal order, but the last of the pages as "start page". Is it possible to configure this?

Start page = 0?cmd=last

Well, I guess this is not what you want either, correct? You would like to see the listing page with ~20 entries. The first one you can access easily via "<logbook>/page1", but the number of the last page varies over time. I would have to add a new functionality like "<lobook>/page_last", which automatically gets converted into the correct page number. I will put this on my wishlist.

For the moment, I could satisfy the users by setting the start page to the "All" view, but if it can be implemented in a future version, this would come very handy.

What about

Start page = last10

This shows always the last 10 entries. If you want to see more, you can click on the new menu entry "Last 20 entries" etc.

In principle this would be a good starting point, however, we would like to use the "Previous" and "Next" page selectors to browse (and these don't appear when using the "lastNN" statement for the start page).

Ok, I implemented the last page display per default in revision 1538. If "reverse sort = 0" the last page is shown and if "reverse sort = 1" the first page is shown by default. This way one always sees the page with the latest entries. I hope this accomodates everybody. If not, please complain and I could make it a switch (yet another option Crying ).

I have installed the new version, and it works just fine. It is also MUCH faster than my intermediate solution.
