The firewall blocks incoming connections where appropriate, yes, but it doesn't stop one user binding to a port that another user expected to be able to use. "Ownership" of ports (1-1023) shouldn't be something only root (via CAP_NET_BIND_SERVICE) has. Lots of services also don't have standard ports below 1024 and it's useful to be able to prevent users from binding to them too. -- Simon Arlott - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
