| * Local port number conventions: |
| * |
| * When a user does a bind(2) or connect(2) with a port number of zero, |
| * a non-conflicting local port address is chosen. |
| * The default range is IPPORT_HIFIRSTAUTO through |
| * IPPORT_HILASTAUTO, although that is settable by sysctl. |
| * |
| * A user may set the IPPROTO_IP option IP_PORTRANGE to change this |
| * default assignment range. |
| * |
| * The value IP_PORTRANGE_DEFAULT causes the default behavior. |
| * |
| * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers |
| * into the "high" range. These are reserved for client outbound connections |
| * which do not want to be filtered by any firewalls. |
| * |
| * The value IP_PORTRANGE_LOW changes the range to the "low" are |
| * that is (by convention) restricted to privileged processes. This |
| * convention is based on "vouchsafe" principles only. It is only secure |
| * if you trust the remote host to restrict these ports. |
| * |
| * The default range of ports and the high range can be changed by |
| * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto) |
| * |
| * Changing those values has bad security implications if you are |
| * using a stateless firewall that is allowing packets outside of that |
| * range in order to allow transparent outgoing connections. |
| * |
| * Such a firewall configuration will generally depend on the use of these |
| * default values. If you change them, you may find your Security |
| * Administrator looking for you with a heavy object. |
| * |
| * For a slightly more orthodox text view on this: |
| * |
| * ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers |
| * |
| * port numbers are divided into three ranges: |
| * |
| * 0 - 1023 Well Known Ports |
| * 1024 - 49151 Registered Ports |
| * 49152 - 65535 Dynamic and/or Private Ports |
