[vbox-dev] Building own VirtualBox extension Pack and distribute it

[Clemens A. Schulz]

Hi,

I found an entry on this mailinglist about developing an VirtualBox  
extension [1] and asked myself how to compile this extension so that  
it will be possible to distribute it to other people (like the  
official ExtensionPack)?

Is a complete VBox SDK env needed or can the extension pack compiled  
separatly?

Furthermore I have some more detailed questions on the possibilities  
of the Extensions:

My Goal: I want to implement a new network adapter connection type  
(like briged, NAT, etc. that are already available). This network  
connection type should be connect the guest OS to a VPN (with some  
connfiguration window). So it should be possible to get the network  
traffic from the guest OS and put it into the own implemented  
VPN-Client, which should be part of this ExtPack. Is this basicly  
possible? The networktraffic from the guest OS should not be readable  
from any OS network device unencrypted.

Alternativly a new network adapter could be implemnted which  
represents the VPN-Client then. Is this possible/impossible too?

If both is impossible: Any other chance to get something like that running?

Thanks for your answer and have a nice day!

With best regards,
Clemens Schulz
