I used "chown" to pass permissions from root to my deafult user, then restarted the service and now I can make posts. Thank you!

Sometimes this can also be an SELinux issue, if you have that service running. Try "journalctl | grep denied" to see denied resources and consult the SELinux documentation on how to fix that.

Permissions are handled by the operating system and have nothing to do with elog. Make sure you run elog under an account which has write access to the desired directories. Consult Ubuntu documentation how to do that. Sometimes it's helpful to start elog interactively with the -v flag to see some verbose output. Maybe you can spot something there.

Hi all,

I have the same problem on Ubuntu 22.04. I have compiled from the latest tarball and copied all our logbooks from our old Ubuntu 18.04 server to a new Ubuntu 22.04. The logbooks does however not appear when I log in, so I assume ELOG doesn't have read access either?
Any hints on how to set the permissions correctly would be greatly appreciated.

Thanks,
Mikkel

Hello,

I have just installed elog onto an ubuntu focal server using <sudo make install> and I am unable to create new entries.

When I access the log via a windows PC connected to the local network, I can see the demo logbook with the 1 test post, but I cannot create or edit anything.

Attempting to post throws the error:

New entry cannot be written to directory "/usr/local/elog/logbooks/demo/"

Please check that it exists and elogd has write access and disk is not full.

 

 

Please point me in the right direction to correctly set permissions and create aditional log books.

 

Thanks,

Dan

 

 

 

 

  65955   Mon Aug 25 17:23:22 2008 Question Davide Salomonidsalomoni@gmail.comQuestionLinux Grabbing user name from SSL user certificate

With SSL enabled, I'd like to to grab the CN (Common Name) of the user certificate and use that as login authentication method.

I am thinking of the following scenario:

- users with read & write privileges need to have an SSL certificate loaded in their browser. The "Author" field will be pre-set to the CN of the user certificate.

- authorization may be subject to further granularity (e.g. only allow users whose certificate belongs to a certain organization)

- read-only, guest access (without certificate) may or may not be allowed

 

Is there a way to do that?

  Draft   Wed Mar 24 16:11:04 2021  Dominic Schneiderdschneider@mein.gmxQuestionLinux3.1.3-1-1Pre-fill

Hi all together,

I struggle a lot with the following problem:
I try to prefill certain attributes with the value of exactly the same attribute in the last entry made in the same logbook.

I know I have to go with Preset, tried a view hours and searched the forum but i didn't find a thing. Am I overlooking a flag, an option or whatever, or is there just not such a functionality (which I dont believe)?

I thought about:
Preset Test_Attribute = $Test_attribute
Preset Test_Attribute = Re:$Test_attribute
Preset Test_Attribute = $shell(Command to somehow get last entry and this attributes value)
Not succesful though.

I would be very thankful for help, thanks in advance.

Hi Stefan, hi Sebastian,

thank you for your help. Ok I see its not that simple.

Is there maybe a way of executing a Script on submitting, writing the values of the Attributes into an temporary file and loading the values from this file via a preset shell script when opening a NEW entry?

Best wishes & thanks in advance

Sorry Stefan, but it is possible as you have the scripting ability.

The idea is to use "Preset Test_Attribute = $shell(script_to_get_the_last_entry)", where the script asks elog about the details and parses them.
The problem here is, that the elogd already is working to resolve the click on "new entry" request (or similar) and the script can't call elogd until the page is delievered, what is to late.
(If it would, the elogd will hang.)

So the script either has to directly parse all the entry.log files in the logbook folder or you need a second elogd running, which can answer the request from the script.
This second elogd could run on a different port and it doen't need to be public as it only answers internal requests and could use the same config as the "primary" elogd.
My idea for the script uses the python elog module to establish the connection and do the parsing.

I hope this helps as a workaround.
Best wishes,
Sebastian

Thank you very much.

So far I testet all functionalities and scripts to reach my goal. I will post a dummy of the solution later on for future purposes.

Best wishes

That would actually be my recommendation. There is a "execute new" which you can call when submitting a new entry.

  2229   Thu May 17 02:12:52 2007 Question Dennis Seitzdseitz@berkeley.eduQuestionAll Summary view: View only most recent entry for all values of a given attribute?
We are using Elog to track status of hardware assemblies. One attribute we've created is the serial number of an assembly. Other attributes are items like "location" and "status". We have set up these latter attributes with presets to make entry easy and keep entries consistent.

I would like to filter the summary view so it only shows me the most recent entry for every value in the serial number attribute. This would be very useful for quickly viewing the present status and location of every assembly, for example.

I can't find a way to do this in the documentation. Is it possible? If not, may I submit a request for this feature?

I am very impressed with the Elog and it has become an essential part of our record keeping. Thank you for a very useful and well implemented application!

I don't know if that is what you want, but have you tried clicking on the column headings in the summary view to sort the table according to that attribute:



Rather than simply sorting, I would like to actually reduce the number of entries listed to show only the most recent entry for each serial number. In this way, I can see at a glance what the present status of each serial number is. This is similar to Quick Filters but would be a "Most Recent" filter that could be applied conditionally, for example: "Most Recent" -> "By Serial".

Here is the display now:


Here is what I'd like to have the option to view (I used a graphic editor to fake it):


It would also be nice to have the option to then sort the resultant view, for example, to group together all serial numbers that have the same status.

Is this a little clearer? It's just a suggestion - this is not terribly important, but if it were possible I think it would be useful.

Thanks!
