183 * Local port number conventions:
185 * When a user does a bind(2) or connect(2) with a port number of zero,
186 * a non-conflicting local port address is chosen.
187 * The default range is IPPORT_RESERVED through
188 * IPPORT_USERRESERVED, although that is settable by sysctl.
190 * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
191 * default assignment range.
193 * The value IP_PORTRANGE_DEFAULT causes the default behavior.
195 * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
196 * into the "high" range. These are reserved for client outbound connections
197 * which do not want to be filtered by any firewalls.
199 * The value IP_PORTRANGE_LOW changes the range to the "low" are
200 * that is (by convention) restricted to privileged processes. This
201 * convention is based on "vouchsafe" principles only. It is only secure
202 * if you trust the remote host to restrict these ports.
204 * The default range of ports and the high range can be changed by
205 * sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
207 * Changing those values has bad security implications if you are
208 * using a a stateless firewall that is allowing packets outside of that
209 * range in order to allow transparent outgoing connections.
211 * Such a firewall configuration will generally depend on the use of these
212 * default values. If you change them, you may find your Security
213 * Administrator looking for you with a heavy object.
215 * For a slightly more orthodox text view on this:
216 * ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
218 * port numbers are divided into three ranges:
219 * 0 - 1023 Well Known Ports
220 * 1024 - 49151 Registered Ports
221 * 49152 - 65535 Dynamic and/or Private Ports
225 * Ports < IPPORT_RESERVED are reserved for
226 * privileged processes (e.g. root). (IP_PORTRANGE_LOW)
227 * Ports > IPPORT_USERRESERVED are reserved
228 * for servers, not necessarily privileged. (IP_PORTRANGE_DEFAULT)
230 #define IPPORT_RESERVED 1024
231 #define IPPORT_USERRESERVED 5000
234 * Default local port range to use by setting IP_PORTRANGE_HIGH
236 #define IPPORT_HIFIRSTAUTO 49152
237 #define IPPORT_HILASTAUTO 65535
240 * Scanning for a free reserved port return a value below IPPORT_RESERVED,
241 * but higher than IPPORT_RESERVEDSTART. Traditionally the start value was
242 * 512, but that conflicts with some well-known-services that firewalls may
243 * have a fit if we use.
