OCS Agent fails to download meta data file

Question

Hey,

I'm trying to update my OCS agents from v2.9.2.0 to v2.10.1.0 via deployment package, but it doesn't work properly. I already tried to search similar threads, but nothing works for me. Package i create looks like this:

Should zip file contain only .exe file or all files included in downloaded agent folder? Tried both options, but neither works. When I assign package to user and run inventory, it logs error as shown below:

And download.log looks like this:

I have full access to download folder and can see the files there.

Server info:

• PHP: 8.1.2

• Database Server: Ubuntu 22.04 version 10.6.11-MariaDB-0ubuntu0.22.04.1
• OCS server version: 2.11.1

Any help would be appreciated. Thanks in advance.

Answer 1

As you can read in the manual (documentation), OCS Packager is NOT designed to update agent ...

IMHO the best is using an deploiement package with a script running ocs-setup.exe with good parameters ... But also with agent 2.9.2, it's not very IMPERATIVE to upgrade to 2.10 ...

Answer 2

Thanks for the reply,

If it's not designed to update agent then why it's literally an example of what you can do with packager... :
https://wiki.ocsinventory-ng.org/05.Deployment/Deploying-packages-or-executing-commands-on-client-hosts/#example-deploying-new-version-of-service-agent-for-windows

That's a bit confusing.

Do you have any tutorials which can help me create package with working script?

Answer 3

Sorry, I use the old way to create package :

- I create a directory

- I copy the .exe and other files

- I create a script 'install.cmd' which launch installation

- I zip all files in 'zip file' and I choose Execution with 'install.cmd'

For agent upgrade, I use an one line script like 'ocs-setup.exe /s /no_splash /no_systray /ssl=0 /server=.... /tag=xxx /now /upgrade'

So after another day of trying to fix this, I'm now stuck on this error:

I have self signed certificate and I can access webpage via https address.

My CN in certificate is just ipaddress, should it also contain http or https at the begining or /ocsinventory at the end or both?
I also have this apache error but i don`t know if thats related to ssl problem:

ocsinventory-server: Bad setting. `IPDISCOVER_LINK_TAG_NETWORK` is not set. Default: `0`

Thanks for help.

Hello! I'm facing with your first issue:

AGENT =>  Communication Server asked for Package Download
ERROR *** DOWNLOAD => Failed to download Metadata file

About your last one, i think could be solved checking in General config, Deployment, last option (HTTP).

Then on the agent was installed, if Windows: check the "C:\ProgramData\OCS Inventory NG\Agent\ocsinventory.ini" file, SSL must be equal to zero:

[HTTP]
Server=http://192.168.4.33/ocsinventory
SSL=0
