|
* Local port number conventions:
|
|
*
|
|
* Ports < IPPORT_RESERVED are reserved for privileged processes (e.g. root),
|
|
* unless a kernel is compiled with IPNOPRIVPORTS defined.
|
|
*
|
|
* 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_ANONMIN to IPPORT_ANONMAX, although
|
|
* that is settable by sysctl(3); net.inet.ip.anonportmin and
|
|
* net.inet.ip.anonportmax respectively.
|
|
*
|
|
* 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 is the same as IP_PORTRANGE_DEFAULT,
|
|
* and exists only for FreeBSD compatibility purposes.
|
|
*
|
|
* 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 range is IPPORT_RESERVEDMIN to IPPORT_RESERVEDMAX.
