Cannot establish communication : 500 Can't connect to

I have a problem with SNMP function and I would need help to know if there's a cert problem or a server installation mistake. I read that we need to configure ocsinventory-agent.cfg this way to make SNMP function works:

basevardir=/var/lib/ocsinventory-agent
debug=1
download=1
ca=/etc/pki/CA/certs/cacert.pem
tag=OCS Server
server=https://10.194.97.125/ocsinventory
logfile=/var/log/ocsinventory.log

I have the next log when ocsinventory-agent.cfg is configured this way:

 [Tue Sep 20 14:32:04 2016][debug] [download] Calling download_start_handler
[Tue Sep 20 14:32:04 2016][debug]  - LWP loaded

</REQUEST>
[Tue Sep 20 14:32:04 2016][error] Cannot establish communication : 500 Can't connect to 10.194.97.125:443

Otherwise, when we configure the ocsinventory-agent.cfg file with server=http://10.194.97.125/ocsinventory ( without https ), we get this log:

  <RESPONSE>NO_ACCOUNT_UPDATE</RESPONSE>
</REPLY>
';

[Tue Sep 20 14:37:59 2016][debug] Calling handlers : `end_handler'
[Tue Sep 20 14:37:59 2016][debug] [snmp] Calling snmp_end_handler

[Tue Sep 20 14:37:59 2016][debug] [download] End of work...

So the agent is reaching the server, but obviously  can't execute the SNMP function because the current ocsinventory-agent.cfg configuration.

--------------------------------------------------

Said that, why is there an 500 connection error when we configure ocsinventory-agent.cfg file with server=https://10.194.97.125/ocsinventory, if in fact the server is configure this way ?

Hi,

How have you build your certificate?

I just saw what was missing. Now SNMP feature is working because ocsinventory-agent.cfg have the value ssl=0 specified.

However, SNMP only scans in the same network where is located the agent, even if I specify a different one as I shown in the next screen

What's what I'm missing ?The OCS Server es 2.1.2 version

I'm reaching that network through snmpwalk by the way:

root@ocsinventory-ng ~# snmpwalk -v 2c -c 'SportiumOCS' 10.24.10.100
SNMPv2-MIB::sysDescr.0 = STRING: Linux md-vscores 3.16.0-30-generic #40~14.04.1-Ubuntu SMP Thu Jan 15 17:43:14 UTC 2015 x86_64
