* Local port number conventions: |
| 283 |
* |
| 284 |
* When a user does a bind(2) or connect(2) with a port number of zero, |
| 285 |
* a non-conflicting local port address is chosen. |
| 286 |
* The default range is IPPORT_HIFIRSTAUTO through |
| 287 |
* IPPORT_HILASTAUTO, although that is settable by sysctl. |
| 288 |
* |
| 289 |
* A user may set the IPPROTO_IP option IP_PORTRANGE to change this |
| 290 |
* default assignment range. |
| 291 |
* |
| 292 |
* The value IP_PORTRANGE_DEFAULT causes the default behavior. |
| 293 |
* |
| 294 |
* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers |
| 295 |
* into the "high" range. These are reserved for client outbound connections |
| 296 |
* which do not want to be filtered by any firewalls. |
| 297 |
* |
| 298 |
* The value IP_PORTRANGE_LOW changes the range to the "low" are |
| 299 |
* that is (by convention) restricted to privileged processes. This |
| 300 |
* convention is based on "vouchsafe" principles only. It is only secure |
| 301 |
* if you trust the remote host to restrict these ports. |
| 302 |
* |
| 303 |
* The default range of ports and the high range can be changed by |
| 304 |
* sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto) |
| 305 |
* |
| 306 |
* Changing those values has bad security implications if you are |
| 307 |
* using a stateless firewall that is allowing packets outside of that |
| 308 |
* range in order to allow transparent outgoing connections. |
| 309 |
* |
| 310 |
* Such a firewall configuration will generally depend on the use of these |
| 311 |
* default values. If you change them, you may find your Security |
| 312 |
* Administrator looking for you with a heavy object. |
