|
---|
[43171] | 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
|
---|
