363 |
|
---|
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
|
---|
