nmap bloqued

[Oscar Aceña <oscaracena () yahoo es>]

Hello,
My question is simple: Can anyone stop scans with nmap in a whole net? I
ask this because i was doing some tests in my net with nmap and only a
pair of them were ok. The other machines returned always down, and i
know this is imposible, because i had scanned them before.

Sorry my speech. I know very few of english language. (If only you could
write in spanish... but that's not imperant :-)
