[root@ocs ~]# ocsinventory-agent -V

Ocsinventory unified agent for UNIX, Linux and MacOSX (2.4.2)

Even with the subnet registered manually, the Agent cannot scan the network in question 192.168.21.0/27

Answer 1

Hi,

There is no nothing to do on the client. All is made on the server. Please read the documentation.

Ocsinventory::Agent::Backend::IpDiscover::Nmap disabled because of a 'runMeIfTheseChecksFailed' in 'Ocsinventory::Agent::Backend::IpDiscover::Nmap'

I followed the documentation, I now have this error!

Answer 3

Have you installed nmap perl module and nmap on the client ?

Frank

Answer 4

yes.
 

the problem that I can't scan on other networks, which were registered on the web interface. Example: 192.168.5.0/24 192.168.21.0/27 OCS does not scan these other networks. on the network on which it is installed 172.16.1.0/24 works perfectly.
