Decrease network usage (check hosts and services)

[Rivanor P. Soares]

I also can do this with 'ping', to send only one packet.
But look at the statistics (from NTop):

Network Traffic: Total Data (Sent+Received)
Host: gerenciamento
Data: 105,8 MB / 40,1 % from total traffic analyzed
TCP: 24,0 MB
UDP: 1,6 MB
ICMP: 79,6 MB

Being measured since July 18, from now. And maybe I mismatch the values (~14 MB in a day). Sorry! :)
But the values above are for all the hosts being checked (total: 95 hosts).

If I didn't make myself clear about all the situation, let me know.

Thanks
