00301  * Local port number conventions:
00302  *
00303  * When a user does a bind(2) or connect(2) with a port number of zero,
00304  * a non-conflicting local port address is chosen.
00305  * The default range is IPPORT_HIFIRSTAUTO through
00306  * IPPORT_HILASTAUTO, although that is settable by sysctl.
00307  *
00308  * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
00309  * default assignment range.
00310  *
00311  * The value IP_PORTRANGE_DEFAULT causes the default behavior.
00312  *
00313  * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
00314  * into the "high" range.  These are reserved for client outbound connections
00315  * which do not want to be filtered by any firewalls.  Note that by default
00316  * this is the same as IP_PORTRANGE_DEFAULT.
00317  *
00318  * The value IP_PORTRANGE_LOW changes the range to the "low" are
00319  * that is (by convention) restricted to privileged processes.  This
00320  * convention is based on "vouchsafe" principles only.  It is only secure
00321  * if you trust the remote host to restrict these ports.
00322  *
00323  * The default range of ports and the high range can be changed by
00324  * sysctl(3).  (net.inet.ip.port{hi,low}{first,last}_auto)
00325  *
00326  * Changing those values has bad security implications if you are
00327  * using a stateless firewall that is allowing packets outside of that
00328  * range in order to allow transparent outgoing connections.
00329  *
00330  * Such a firewall configuration will generally depend on the use of these
00331  * default values.  If you change them, you may find your Security
00332  * Administrator looking for you with a heavy object.
00333  *

00336  *            ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
