@ChillerDragon in regard to the 0.7 protocol. If the server does not have a password, does one simply send an empty string? and what happens if the password is incorrect?[CLIENT->SERVER] Version and password.
the client sends its password regarldess wether the server wants one or not thats also how you leak your password to all servers you connect to

if you never set a password it just sends a empty string which is just a single nullbyte

idk what happens then if you want to investigate that i highly recommend using heinrichs dissector but i assume the server just sends a ctrl close with wrong password
