If you have iptables properly configured you are probably
well protected from attacks. This ports are not problematic,
people use to try the standard ports or Netbios ports.
I don't think crackers are quite interested in this ports,
but you can never be too sure.

ESPAŅA
The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
