You have the power to exec() the daemon in question with CAP_NET_BIND_SERVICE capability inherited from the parent, and that will be the only "extra" capability the process will have. So there is in fact an existing mechanism for doing this. If you have the power to set the sysctl, you have the power to give the capability to an arbitrary process which you want to get lower ports but do not trust to run completely as root. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
