364 This is the deal:
365
366 Four new options are available:
367 - VNCAddress4 -> IPv4 address to use
368 - VNCPort4 -> IPv4 Port to use
369 - VNCAddress6 -> IPv6 address to use
370 - VNCPort6 -> IPv6 port to use
371
372 By default we prefer IPv6 over IPv4.
373
374 The address length can be unlimited as the interface identifier is not
375 limited by any specs - if this is wrong, and someone knows the line
376 and the RFC number, i'd appreciate a message :)
377
378 THE MAXIMUM LENGTH OF THE RETURNED VALUES MUST NOT BE GREATER THAN:
379
380 --> VBOX_ADDRESS_OPTION_MAX <--
381
382 which is defined at the top of this file.
383
384 The way to determine which address to use is as follows:
385
386 1st - get address information from VRDEProperties
387 "TCP/Address"
388 "TCP/Ports"
389
390 2nd - if the address information is IPv4 get VNCAddress6 and VNCPort6
391 2nd - if the address information is IPv6 get VNCAddress4 and VNCPort4
392 2nd - if the address information is EMPTY and TCP/Ports returns 3389,
393 check both, VNCAddress4 and VNCAddress6 as well as the ports.
394 3389 is not a valid VNC port, therefore we assume it's not
395 been set
396
397 If one of the addresses is empty we assume to listen on any
398 interface/address for that protocol. In other words:
399 IPv4: 0.0.0.0
400 IPv6: ::
401
402 2nd - if everything is empty -> listen on all interfaces
403
404 3rd - check if the addresses are valid hand them to libvncserver
405 to open the initial sockets.
406
407 4th - after the sockets have been opened, the used port of the
408 address/protocol in TCP/Address is returned.
409 if TCP/Address is empty, prefer IPv6
410
