VP - The ventrilo protocol is the one used by Ventrilo to encrypt and decrypt VoIP chatting.
- ["TCP"]: Typically, VP uses ["TCP"] as its transport protocol. The TCP port for VP traffic is 3784 (Depending on server).
v2.3.0 [http://pastebin.ca/71370 HERE] (Long text pasted on pastebin.ca)
The preshared encryption key is the same as the one for 2.3.0 and the key exchange and encryption method seem to be the same. However, a type 0x34 packet now siganls a change in encryption sometime shortly after connecting and displaying the server status.
The login packet has also changed to type 0x48 and has an additional 16 bytes of data immediately before the client version string.
The client has a quirk of its own that makes running it through the decryption proxy somewhat of a pain. It first connects and gets the server status via UDP before it will even attempt to connect. If you proxy it through a port that does not match what the remote server claims to be it will also not connect. Either the packet must be modified with the redirected UDP port or they must be changed to match the remote end. This means you may no longer block the UDP port to prevent people from checking to see who's on.
The VP dissector is non-existing.
