Answer 1

Hello,

error] Failed to create /var/lib/ocsinventory-agent/http:__ocsinventory-ng_ocsi                                                                             nventory directory: Permission denied

states that the user adii has no permissions to write to mentioned directory. You have to run the command as root.

There is a problem with name resolution (DNS). Either create a DNS entry for ocsinventory-ng or add an entry to /etc/hosts or use the IP of the server as Frank already explained.

Answer 2

Hi,

First agent must be launched as root user. Second add --server https://@ip/ocsinventory on the command line and retry.

So, now my question is , how do i get the SNMP inventory results to show in the web interface 

HOW CAN I SEE  THE TABLE THAT'S SUPPOSED TO BE CONTAINING ALL THE SNMP DEVICES SCANNED BY OCS AGENTS???
