Problems Ubuntu agent 2.8.1 to OCS server [closed]

Question

Hi

I have the following problem. I have installed the agent on some Ubuntu machines that I need to register on the OCS Server. I have followed the instructions on how to install the agent in version 2.8.1 on an Ubuntu machine. I have followed the steps indicated to configure the agent when you execute "make install", but in the log file I see the following output:

[Tue Apr 27 11:01:34 2021][error] Cannot establish communication : 500 read timeout
 

The configuration file has the following values:

logfile = / var / log / ocs-inventory-agent.log

snmpretry = 2

tag = _Ubuntu_servers

server = http: //ocsinventario.mydomain.com

snmptimeout = 3

basevardir = / var / lib / ocsinventory-agent

debug = 1

snmp = 1

I have tried to change the value of the "server", even putting the path where I have the OCS Server installation which would be in the path http://ocsinventario.mydomain.com/ocsreports, but any change gives me the error that you see above :

[Tue Apr 27 11:01:34 2021] [error] Cannot establish communication: 500 read timeout

From Ubuntu machines I can reach the OCS server, by pinging and by telnet to port 80.

What could be failing to not contact Ubuntu machines in OCS Server version 2.8? Best regards.

Answer 1

Hi,

What errors have you in /var/log/apache2/error.log file ?

Best Regards

Answer 2

Thanks for the quick answer.

When I manually run the OCS agent to contact the server using the following command: root @ tfvs0727: /etc/cron.d# / usr / local / bin / ocsinventory-agent --lazy

On the server side of OCS in Apache's error_log it shows nothing. I check the output of /var/log/httpd/access.log from the OCS server and I see the following request from the IP of the Ubuntu machine:

172.16.255.47 - - [Apr / 27/2021: 12: 15: 21 +0100] "POST / ocsinventory HTTP / 1.1" 200 234 "-" "OCS-NG_unified_unix_agent_v2.8.1"

So a correct request is arriving and it connects correctly, but after a few minutes it gives the message in the OCS agent log [Tue Apr 27 12:18:21 2021] [error] Cannot establish communication: 500 read timeout [Tue Apr 27 12:18:21 2021] [info] No previous PROLOG_FREQ found - using fallback delay (3600 seconds)

Regards again

As you wrote:

"What could be failing to not contact Ubuntu machines in OCS Server version 2.8? Best regards."

and Agent is:

"Tue Apr 27 10:58:34 2021][debug] Ocsinventory unified agent for UNIX, Linux and MacOSX 2.8.1"

If it's true this is the problem. Try upgrade server od use Agent that is =<Server Version. I had this issue on my first install so now it's the first that I check ;) .

Answer 4

when agent version is bigger as server version an 400 error is generated. This is not the case here.

The url is not correct => server=http://ocsinventario.mydomain.com

You must have server = http://ocsinventario.mydomain.com/ocsinventory

Answer 5

frankb is wright, this config will not work, server in the agent side must be:

http://ocsinventario.mydomain.com/ocsinventory

or 

http://your_server_ip/ocsinventory

of course if you doesn't configure apache in non standard way  :)
