I will give it a look as soon as i get my hands on the new server.
Right now the server has the option "online-mode=true|false" in "server.properties"
If it's set to true all accounts are doublechecked against 194.28.157.42 (
www.minecraft.net)
and you have to supply a valid username
and password like this:
Code:
0x00, 0x00, 0x00, 0x06, 0x00,
[len of name],
[string name],
0x00, 0x08,
[string "password"],
[len of password],
[string password],
0x00
I'm not 100% sure this packet is correct, as i said i need to get my hands on the new server first...
