Ocsinventory-agent don't run under fedora

Hy guys,

i have install  ocsinventory-agent 2.3 under Fedora 26 and i schedule service with cron:

00 * * * * /usr/local/bin/ocsinventory-agent -s <dns name server>

but in Ocs Server the hosts haven't  ip and cpu clock.

If launch this command under shell:

ocsinventory-agent -s <dns name server>

ip and cpu are display.

i have some problem under centos 7.

Any idea?

Thanks very much
