leggendo su lwn.net c'e' questa notizia che mi lascia molto perplesso...

Red Hat 7.1 installs more securely out of the box than Version 7.0 did. By
default, it installs firewall settings that block incoming IP traffic on ports
below 1024 (with the exception of ports used for automatic IP address
assignment) plus higher-numbered ports used by Network File System and X Window.
We could easily re-enable ports for common server applications if we desired.

che senso ha bloccare il traffico sotto la porta 1024???

bah....
spero che l'articolo sia scritto male... o spero di aver capito sbagliato.
