VRDP can't bind to localhost on OSX Snow Leopard -> fixed in SVN

[Jinn Koriech]

Running a guest machine on OSX with RDP listening on localhost doesn't work.

RDP is able to bind to *:port, but not to 127.0.0.1:port.

To reproduce:

1. Start a VM from the command line

   $ /Applications/VirtualBox.app/Contents/MacOS/VBoxManage showvminfo gentoo | grep -i rdp
   VRDP:            enabled (Address 127.0.0.1, Port 3390, MultiConn: off, ReuseSingleConn: off, Authentication type: null)
   VRDP Connection:    not active
   
   $ /Applications/VirtualBox.app/Contents/MacOS/VBoxHeadless --startvm gentoo
   

2. Relevant lines from the log file are:

   00:00:00.320 VRDP: TCP server failed to bind to a port: 3390 []
   00:00:00.320 VRDP: TCP server closed.
   00:00:00.320 VRDP: Failed to start VRDP-IN thread, rc = VERR_NET_ADDRESS_IN_USE
   00:00:00.325 Warning: failed to launch VRDP server (VERR_NET_ADDRESS_IN_USE): 'VRDP server port 3390 is already in use'
   

3. Update the vm config to bind to any interface and restart the vm and it works.

   $ /Applications/VirtualBox.app/Contents/MacOS/VBoxManage modifyvm gentoo --vrdpaddress 0.0.0.0
   $ /Applications/VirtualBox.app/Contents/MacOS/VBoxManage showvminfo gentoo | grep -i rdp
   VRDP:            enabled (Address 0.0.0.0, Port 3390, MultiConn: off, ReuseSingleConn: off, Authentication type: null)
   
   $ /Applications/VirtualBox.app/Contents/MacOS/VBoxHeadless --startvm gentoo
   

4. Relevant line from logs now show that RDP is working

   00:00:00.229 VRDP: TCP server listening on port 3390.
   

5. And netstat confirms this, where previously there was nothing.

   $ netstat -anfinet | grep 3390
   tcp4       0      0  *.3390                 *.*                    LISTEN
