|
* Local port number conventions:
|
| 229 |
|
|
*
|
| 230 |
|
|
* When a user does a bind(2) or connect(2) with a port number of zero,
|
| 231 |
|
|
* a non-conflicting local port address is chosen.
|
| 232 |
|
|
* The default range is IPPORT_HIFIRSTAUTO through
|
| 233 |
|
|
* IPPORT_HILASTAUTO, although that is settable by sysctl.
|
| 234 |
|
|
*
|
| 235 |
|
|
* A user may set the IPPROTO_IP option IP_PORTRANGE to change this
|
| 236 |
|
|
* default assignment range.
|
| 237 |
|
|
*
|
| 238 |
|
|
* The value IP_PORTRANGE_DEFAULT causes the default behavior.
|
| 239 |
|
|
*
|
| 240 |
|
|
* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
|
| 241 |
|
|
* into the "high" range. These are reserved for client outbound connections
|
| 242 |
|
|
* which do not want to be filtered by any firewalls. Note that by default
|
| 243 |
|
|
* this is the same as IP_PORTRANGE_DEFAULT.
|
| 244 |
|
|
*
|
| 245 |
|
|
* The value IP_PORTRANGE_LOW changes the range to the "low" are
|
| 246 |
|
|
* that is (by convention) restricted to privileged processes. This
|
| 247 |
|
|
* convention is based on "vouchsafe" principles only. It is only secure
|
| 248 |
|
|
* if you trust the remote host to restrict these ports.
|
| 249 |
|
|
*
|
| 250 |
|
|
* The default range of ports and the high range can be changed by
|
| 251 |
|
|
* sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
|
| 252 |
|
|
*
|
| 253 |
|
|
* Changing those values has bad security implications if you are
|
| 254 |
|
|
* using a a stateless firewall that is allowing packets outside of that
|
| 255 |
|
|
* range in order to allow transparent outgoing connections.
|
| 256 |
|
|
*
|
| 257 |
|
|
* Such a firewall configuration will generally depend on the use of these
|
| 258 |
|
|
* default values. If you change them, you may find your Security
|
| 259 |
|
|
* Administrator looking for you with a heavy object.
|
| 260 |
|
|
*

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

*
|
