Okay, finally got Wireshark to work on the MiiVi server. Here's the
deal:
 
I get the encrypted ping:
{ 0x61, 0xef, 0xb9, 0x16, 0x75, 0x28, 0xb3 }
Decrypt it and get:
{ 0x00, 0x00, 0x00 }
Yay teh shit works, right?
 
I get the pierce, I'll assume by the length:
{ 0xb8, 0xde, 0xa1, 0x23, 0xff, 0x0f, 0xc4, 0xd9, 0x51, 0x93, 0x8d,
0x85, 0x3d, 0xe0, 0xa8, 0x87, 0x5a, 0xf6, 0x93, 0x69, 0xdc, 0xdb, 0x8c,
0x5d, 0x30, 0x2e, 0x1c, 0xfd, 0x8b, 0xcf, 0x8f, 0x2a, 0xf1 }
Decrypt it and get:
{ 0x03, 0x01, 0x19, 0x0c ..... }
Doh! WTF is a 0x03 op code? Also the length is screwed, since it should
come out to be 1A.
 
Both of these are from my office machine, so why does one work and the
other is borkered? I checked several ping packets and they all work.
All the other packets are fucked. Can you check your encryption is
being happy for the piercing and not just the pinging? The weird thing
is the packet aren't unencrypted either.
