Answered: Erreur installation paquet - kill Windows process

Thu, 07 May 2026 07:09:46 +0000

Ça ressemble effectivement à un souci lié au taskkill. Peut-être que le processus ne se ferme pas correctement avant le lancement du MSI. Tu peux essayer d’ajouter une petite pause après la commande taskkill, par exemple avec timeout /t 3, pour laisser le temps à Windows de terminer le processus complètement.

Tu peux aussi tester le script manuellement en mode administrateur pour voir si le code erreur apparaît encore. Certaines versions récentes de Windows ou du client OCS semblent être un peu plus strictes sur les droits et les processus actifs.

Answered: Prevent OcsService.exe file from disappearing

Wed, 22 Apr 2026 21:35:43 +0000

This has happened in the companies I manage.

The OCS Agent services simply disappear.

In this case, I created a BAT/CMD script that validates the existence of the service; if it doesn't exist, it creates it pointing to the file in its correct directory.

If the file doesn't exist, it reinstalls the OCS Agent.

If everything is OK, it simply forces an inventory, which doesn't cause any harm.

Retrieve extra info from Android Agent

Mon, 21 Jul 2025 18:43:01 +0000

Hi there!
Thanks for your extensive and great work with OCS Inventory.

This is our current setup:
Version OCSReports: 2.7 (Running on Debian GNU/Linux server)
OCS Inventory NG android Agent version 2.7

We are using in a production server since some time without problems. We have windows, linux and macOS agents, and several standard and custom plugins deployed working fine.

Now we're trying to extend the use to android phones also. We've tested the agent, it's working fine, but we would like to obtain some other information (for example the lastpublicip plugin)...I can't find information regarding the plugins deployment for android. Maybe we can just run some scripts in Android and extract the contents or just upload the results...
Could you please tell me if that's possible and how to advance on that?
We're looking for a setup for standard users (no adb, termux, or root access), but if requires something else we could evalute it of course.

Thanks in advance

First, you need verify if a computer include data from plugins : execute manually the agent and check the xml file

Second, if inventory include plugins data, the date are loaded in SQL table, the check the table.

You try the second point, so try before the first point.

Answered: Unable to install the agent on Windows

Fri, 29 Nov 2024 22:31:22 +0000

I recently faced an issue while installing the OCS Inventory NG Agent on a Windows machine, where the agent would not register with the OCS Server. Despite following the standard installation process, the agent installation seemed to complete successfully, but the registration with the server was still not happening. Here's the installation log I received during the process:

The setup process initially checked the system and seemed to go fine—ensuring the system was compatible (Windows 2000 or higher), and that the user had the necessary administrative privileges. However, I ran into issues when the setup tried to assign read/write permissions on the directory C:\ProgramData\OCS Inventory NG\Agent. The following errors were logged:

SetACL allowing Users / Power users read/write permissions...Result: error SetACL propagating inherited permissions...Result: error

These errors indicated that the agent had trouble setting the correct permissions, which could be why the agent wasn't registering. It also tried to stop services and kill processes related to OCS Inventory, but had no success in terminating some processes.

After installation, the agent did not start properly, and there was no successful registration of the OCS Inventory Service into the Windows Service Manager, which led me to believe there was an issue with the permissions or missing dependencies.

Here's what I did to resolve the issue:

Recheck Permissions: I manually ensured that the directory C:\ProgramData\OCS Inventory NG\Agent had the correct read/write permissions for both Users and Power Users. I also ran the installer as Administrator.
Service Registration Issues: I noticed that the service registration failed in the log. To fix this, I manually registered the service by running the following command from the command prompt:
```
sc create "OCS Inventory Service" binPath= "C:\Program Files\OCS Inventory Agent\ocsinventory.exe" start= auto
```
Firewall Configuration: Even though the installer skipped configuring the firewall (as I was using a Windows version below Vista), I made sure to check the firewall settings and allow the necessary ports for OCS to communicate with the server.
Verify Installation: After manually fixing the permissions and services, I restarted the machine and confirmed that the agent registered properly with the OCS Server.

The Vultr documentation has been a huge help in understanding how to handle agent installations and permissions better on Windows. I highly recommend checking out the installation guide for MySQL on Ubuntu, as it has similar detailed steps for troubleshooting and making sure everything is configured correctly. It helped me better understand system services and configurations, and I applied some of the insights from that guide.

For anyone encountering similar issues, here's a helpful link to the Vultr MySQL installation guide on Ubuntu:
Install MySQL on Ubuntu 20.04 in Simple Steps

Hopefully, this approach works for anyone experiencing similar issues with OCS Inventory NG installation!

I recently set up an OCS Inventory server on a Debian system and successfully completed the initial setup at (http://192.168.10.199/ocsreports/).

Issues with OCS Inventory Agent on CentOS 7

Wed, 02 Oct 2024 18:54:37 +0000

Hello everyone,
My OCS Server is on Ubuntu 22, and my OCS Agents are installed on several machines, including Ubuntu 22, ZorinOS 15, and CentOS 7. My inventory got information about all the machines, except for the CentOS 7 machines. It's like the agent is not communicating with the server.

I’ve checked the agent configuration, here's my ocsinventory-agent.cfg on CentOS: (NOT WORKING)

# OCS Inventory "Unix Unified Agent" Configuration File

# options used by cron job overides this (see /etc/sysconfig/ocsinventory-agent)

# Server URL, unconmment if needed

server = https://ocs.peter.gov.br/ocsinventory

local = /var/lib/ocsinventory-agent

# Administrative TAG (optional, must be filed before first inventory)

# tag = your_tag

# How to log, can be File,Stderr,Syslog

logger = Stderr

logfile = /var/log/ocsinventory-agent/ocsinventory-agent.log

And here's my ocsinventory-agent.cfg on Ubuntu: (WORKING)

logfile=/var/log/ocs

debug=1

tag=Desktop

basevardir=/var/lib/ocsinventory-agent

server=https://ocs.peter.gov.br/ocsinventory

I tried to use the same configs on CentOS but doesn't work anyway.

Could someone help me identify what might be?

Bonjour, je ne sais pas si les choses ont évolué, mais je suis avec la version 2.11.1 des agents et il arrive souvent que nous n'ayons pas l'utilisateur connecté dans les informations remontées. Particulièrement lorsqu'un ordinateur a été redémarré et qu'aucune session n'est ouverte. J'en déduis que c'est parce que l'agent roule avec le compte système et que lorsqu'il récolte l'inventaire aucune session n'est ouverte.

Ne serait-il pas possible de collecter le nom de la dernière session qui a été ouverte tout simplement?

Agents cannot be deployed on the network

Thu, 30 May 2024 11:42:09 +0000

Hey, I'm currently doing an internship and my job is to deploy ocs inventory on the network. My ocs 2.12.1 server is on debian 12. I've installed an agent 2.10.1.0 manually on a windows machine to check that everything was working, so far no problem. Now I'm getting down to the serious business of deploying my agent on the network using the agent deployment tool. I added psexec, putty and pscp in the options, then I added the range of ip addresses on which I want to deploy my agents (I don't use the active directory, because some computers on the network aren't connected to the domain), then I followed the official documentation for the rest as well as several different tutorials and here I am at the moment of deploying by pressing start and that's when the problems start.

Here are the 2 error messages I may encounter:

Host <172.16.142.10> *** ERROR *** Connecting remote host: The network path was not found.

Host <172.16.142.11> *** ERROR *** Remote host does not accept connections

I have all admin right, firewall was check thats not seem to be an issue. Im on this for 2 days actualy im stuck.

Agent Conection SSL with LetsEncrypt

Thu, 25 Apr 2024 20:15:53 +0000

I have Ubuntu 20.04.6 LTS and I configured my server with https connection using LetsEncrypt certificate. I connect my OCSServer with https://fqdn/ocsreports/ and it is functional. When trying to run my Windows ocsagent with SSL = 1, it shows an error in the log and does not run the PC inventory.

My ocsinventory.ini

Server and Agent cant communicate HTTP 403

Thu, 25 Apr 2024 14:16:10 +0000

Hi everyone,

I am having an issue when sending the agent's info on the server. I get an http 403 error when trying to access to the http://myServerIp/ocsinventory.

When installing the agent and choosing the address, I am making sure it is in the correct way (aka http://myServerIp/ocsinventory)

However the server can't receive the agent's info.

The OcsReports panel seems to be installed proprely and correctly. I have fully access to http://myServerIp/ocsreports.

I put the correct database name, username and password in the configuration files.

After checking the agent's logs, i can see that there is an http error 403, http://myServerIP/ocsinventory access being forbidden.

I have tried searching on the internet but i haven't found any solution, and I have reinstalled a second time to server to make sure I installed the server correctly.

Here's a list of what ive tried :

- Updated my system

- Install php extensions and packages required by the server

- Install and enable perl modules

- Create a database

- Download, configurate the setup.sh (with correct db user and db password) and install

- Configurate (put the correct db name, db user and db password) and enable the 3 .conf files
- Change the ownership of the ocsinventory-reports directory to www-data user, and change the permission to 755

- And finally finishing the installation on http://MyServerIp/ocsreports, and delete the installer.

Please help

Thanks!

-    This info is a test environment, so don’t worry.

Issue is that agent will not work is utilizing SSL, but does work if everything remains as HTTP.

Any help would greatly appreciated.

macOS Packager?

Thu, 18 Apr 2024 14:20:16 +0000

Hi,

It appears the macOS packager is no longer available for download and has been replaced with (OCSNG-Unix-Packager-1.0). Is there any documentation on how to package with the config and sh files? I am trying to deploy Mac agent 2.10.0 using Jamf and have no idea where to begin. I deployed the agent to my Windows fleet using Intune with no issues.

If agent is updated earlier than the server ... ?

Wed, 17 Apr 2024 05:59:29 +0000

Good morning everybody

One more beginner question ... I'm quite new in the OCS world so please let me ask this simple (?) question. A first quick forum search didn't led me to the answer, but maybe you know it or know where I can find it:

I'm working on setting up a first OCS inventory for our machines. For this task I installed the agent from the official repo as told at wiki.ocsinventory-ng.org what worked quite well.

But now I'm asking myself what may happen if the agent should get updated as part of a regular update cycle while the server may not be updated, too. Will the agent still be able to communicate with the server. Would be really good to know, at least for minor patches. (I assume it's not possible to be sure about this for major releases, but that's no daily business on the other hand.)

Thanks a lot for your help!

OCS agent in server initiated communication mode?

Wed, 17 Apr 2024 05:51:59 +0000

Good morning everybody

I'm quite new in the OCS world so please let me ask this simple (?) question. A first quick forum search didn't led me to the answer, but maybe you know it or know where I can find it:

Is it possible to establish the communication between OCS server and the client's agent in a server initiated way? We have a few machines running in the www for which it is much easier to let the server connect to them instead of making the server reachable for their agents.

Thanks a lot for your help!
