|
|
* When a user does a bind(2) or connect(2) with a port number of zero,
|
| 157 |
|
|
* a non-conflicting local port address is chosen.
|
| 158 |
|
|
* The default range is IPPORT_RESERVED through
|
| 159 |
|
|
* IPPORT_USERRESERVED, although that is settable by sysctl.
|
| 160 |
|
|
*
|
| 161 |
|
|
* A user may set the IPPROTO_IP option IP_PORTRANGE to change this
|
| 162 |
|
|
* default assignment range.
|
| 163 |
|
|
*
|
| 164 |
|
|
* The value IP_PORTRANGE_DEFAULT causes the default behavior.
|
| 165 |
|
|
*
|
| 166 |
|
|
* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
|
| 167 |
|
|
* into the "high" range. These are reserved for client outbound connections
|
| 168 |
|
|
* which do not want to be filtered by any firewalls.
|
| 169 |
|
|
*
|
| 170 |
|
|
* The value IP_PORTRANGE_LOW changes the range to the "low" are
|
| 171 |
|
|
* that is (by convention) restricted to privileged processes. This
|
| 172 |
|
|
* convention is based on "vouchsafe" principles only. It is only secure
|
| 173 |
|
|
* if you trust the remote host to restrict these ports.
|
| 174 |
|
|
*
|
| 175 |
|
|
* The default range of ports and the high range can be changed by

* sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
|
| 177 |
|
|
*
|
| 178 |
|
|
* Changing those values has bad security implications if you are
|
| 179 |
|
|
* using a a stateless firewall that is allowing packets outside of that
|
| 180 |
|
|
* range in order to allow transparent outgoing connections.
|
| 181 |
|
|
*
|
| 182 |
|
|
* Such a firewall configuration will generally depend on the use of these
