The server does not detect clients (Agent)

Question

Im intalled OCS Server on 2 environments:

1) OCS Server 2.5 on Centos7 with a Windows 10 agent in the same network without firewall with Windos 10 Client (Agent vs 2.4.0)

2) Installed OCs Server / Xampp vs 2.1.2 on Windows 10 and install OCs Agent vs 2.4.0 on the same machines. Local host

In my environments, my server does not detect the client (agent)?

Why?

Thanks regards

Answer 1

hy, first of all the agent does not send the inventory immediately. The client calculates a random number to create a counter. This counter well be decreased.. every second, and after the counter reaches 0 the clients sends the inventory.The reason behind this is, the 1000 of clients could not DDOS the server beause every client has different counters.

But you can decrase the intervall to contact  the server in the following server siede setting

(Configuration > Server > PROLOG_FREQ)

or hook the setting to report the inventory mmediately during the graphical setup of the client.

You also have to use the right url in the client

use http://xxx.xxx.xxx.xxx/ocsinventory

and NOT http://xxx.xxx.xxx.xxx/ocsreports

immediately send the inventory is also possible  with the following method

doubleclick on

C:\Program Files (x86)\OCS Inventory Agent\OCSInventory.exe

Hope this helps

Thanks Sokrata but no functioning....

(Configuration > Server > PROLOG_FREQ) :   was set  1 Hour

"use http://xxx.xxx.xxx.xxx/ocsinventory:"

        http://172.18.0.68/ocsinventory  ,my  agent configuration with localhost IP

172.18.0.68 (Windows 10)   has OCS Server Installed and Client Agent .

"C:\Program Files (x86)\OCS Inventory Agent\OCSInventory.exe

 I'was  applied this solution but the problem persist 

thank you

Answer 3

do you really have ocs-inventory on windows as a server ? i thought this version has been discontinued.
the client version number must be lesser or equal than the server version.

So you can't use old server version (for example 2.1.2) with Client version 2.4.0

Turn off the windows firewall

look at the log file on client

C:\ProgramData\OCS Inventory NG\Agent\OCSInventory.log

post the conntent here

Answer 9

hi !

I have the same problem with version 2.7 agent and server. Does anyone have a solution?

Thank you in advance

Answer 10

if anybody has a problem with OCS-Inventory.. just try first this manual

https://miloszengel.com/ocs-inventory-ng-2-5-install-guide-on-debian-stretch-with-ssl-and-deployment/

Then you test newer version .. but with this manual i am sure you can get it to work.

Kind regards
