This script has to be run as user 'www-data' or as 'root'!
sudo -u www-data nc-who monitor
/usr/local/bin/nc-who: line 60: /tmp/ebtb-logfiles/nc-who.log.lock: Permission denied
When I run as www-data, as suggested above, I get:
/usr/local/bin/nc-who: line 60: /tmp/ebtb-logfiles/nc-who.log.lock: Permission denied
.. loading modules - nc/nextcloud/dev/fd/61: line 67: /usr/local/include/ebtb/prod/fp: Permission denied
When I finally run as root, I get:
.. loading modules - nc/nextcloudPHP Warning: include(/config.php): Failed to open stream: No such file or directory in Standard input code on line 5
PHP Warning: include(): Failed opening '/config.php' for inclusion (include_path='.:/usr/share/php') in Standard input code on line 5

thank you for your feedback and sorry for the late response. You didn’t respond in the thread belonging to this script, so I wasn’t notified right away.
The error message actually indicates that the config directory was not passed on correctly.
The only explanation I can think of is that it has something to do with the rights problems you described.
Yes, it’s true, the script should actually be run completely as root the first time so that the path to the nextcloud installation can be written into the script. That is logged here:
I assume that’s where it went wrong.
Could you please check this output:
If it does not show the path to your nextcloud installation, then run this step again:
and start again from scratch as root:
sudo nc-who
Your feedback provides valuable information that shows me where improvements are still needed.
I wanted to make the script run with unprivileged rights if possible. However, since I have implemented a lot of security features like lock files and such, switching from root to unprivileged is no longer as easy as before. So I still have to make some improvements so that it really works on all systems.
I am sory for that. I will fix that soon, so that log- and lockfiles wil no longer be shared between users and to make it clear, that the first “installation” run must be done as root.

nc-who - Version 2025-02-02 20:05 (latest version)
This utility is similar to the Unix `who` command, allowing you to monitor
live user logins and activities on your nextcloud server-instance.
Usage:
nc-who -h|--help
nc-who monitor
nc-who last
nc-who integrity_check
Options:
-h|--help Display this help message.
monitor Monitor live user logins, ordered by last activity at an
adjustable refresh rate.
* Login status is only available for cookie-based sessions
on a web frontend.
* Last activity is shown for all clients.
last List users sorted by their last login time. This is equivalent
to the output of `occ user:lastseen --all`
* `--all` is actually not available for that occ command.
integrity_check
verify the integrity of this script with signature
It does not work, because you did not configure your server as it is usualy expected:
This shows, that according to /etc/passwd, /var/www is the home directory of the user www-data:
getent passwd www-data | cut -d: -f6
However www-data does not have write permissions in that directory:
ls -ld /var/www
This can be considered as a misconfiguration of the server or at least as unusual.
But since the server admin is free to configure their system as unusually as they wants and I want to make the scripts as idiot-proof as possible, I have taken this into account.
Please try the newest version. It should now work even if the user cannot write to its own HOME directory.
This shows, that according to /etc/passwd, /var/www is the home directory of the user www-data:
getent passwd www-data | cut -d: -f6
However www-data does not have write permissions in that directory:
ls -ld /var/www
That is all correct. Can you tell me, please, how you were able to obtain that data? It would appear that you were running those commands on my server and if that is the case, how were able to do that?
This can be considered as a misconfiguration of the server or at least as unusual.
Could well be… the root ownership I think may have been from the original install, but the group I would have applied later.
I have now changed the ownership of the /var/www folder to www-data. I then ran nc-who, without first upgrading, with no success.
I then ran nc-who again and accepted the offer to upgrade. Again, nc-who would not run:
- Update was successfull. Please start script again
$ sudo nc-who

The .ebtb does exist:
ls -la /var/www
total 48
drwxrwxr-x 12 www-data adm 4096 Feb 11 16:35 .
drwxr-xr-x 14 root root 4096 Nov 22 2023 ..
drwxrwxr-x 3 www-data www-data 4096 Feb 11 16:35 .ebtb
What other info do you need (other than the root password) to figure out what’s going on?
(And “idiot-proof” may not be the most diplomatic term to use, especially when you’re talking to the idiot…)
FWIW, I removed all of the .ebtb directories and removed /usr/local/bin/nc-who.
I then ran the install again, using nc-shares this time, instead of nc-who.
Unsurpisingly, I got the same result:
.. loading modules - nc/nextcloudPHP Warning: include(/config.php): Failed to open stream: No such file or directory in Standard input code on line 5

good morning, unfortunately i’m having the same issue. no matter what I do, it always ends with this error :
root@mj-nextcloud01:~# nc-who
.. loading modules - nc/nextcloudPHP Warning: include(/config.php): Failed to open stream: No such file or directory in Standard input code on line 5

the user www-data definitely has write permissions to its home directory /var/www
the server is:
