Problem's description

hi there,
I was setting up the ocsagent trying to make snmp scan work. the snmp scanning never work properly.
the vm was cloned from vmware on my laptop to proxmox under different subnet, so the network info may be a bit strange
the ipdiscover function does work, but snmp don't
at first i got only the "[download] Option turned off. Exiting." message, the modules.conf shows Modules::Download is not commented

# this list of module will be load by the at run time
# to check its syntax do:
# #perl modules.conf
# You must have NO error. Else the content will be ignored
# This mechanism goal is to launch agent extension modules
use Ocsinventory::Agent::Modules::Download;
use Ocsinventory::Agent::Modules::SnmpScan;
#use Ocsinventory::Agent::Modules::LocalSnmpScan;
use Ocsinventory::Agent::Modules::SnmpFork;
# DO NOT REMOVE THE 1;
1;

and here's my agent config

basevardir=/var/lib/ocsinventory-agent
ca=/etc/ocsinventory-agent/cacert.pem
snmpretry=2
snmptimeout=3
debug=
tag=Server
server=http://10.10.16.218/ocsinventory
logfile=/var/log/ocs_agent.log
nosoftware=0
snmp=1

Inventory log file ( optional )

ocs_agent.log
i took away the user's part : )

also, i saw some tutorial mention that the snmp function will only work when ocsinventory server set https up.
is it necessary?
i thought snmp and ssl are two completely seperate function?

Hi,

For security reasons download and snmp feature need to have HTTPS enabled.
SNMP and SSL are unrelated but we enforce them in order to secure our software.

You can use an already existing CA if you don't want to generate a certificate specific for OCS.
