Hi guys! I was just wondering if it's possible to accept connections from a cracked client IF they are using a certain IP. I'd like to do this so I can do a real-world test of what my staff do when a rule-breaker comes. If I can use a cracked client or something I can do this without borrowing a friends account and possibly having him banned or whatever. The trouble is, I want to keep my server in online mode so other people (not me) can only join with premium accounts. I was thinking a plugin or something might be able to achieve this. If there isn't a plugin already, if someone can tell me what the Java methods for skipping the Mojang auth system is, that would be helpful too. (I can handle the rest) Thanks guys! P.S Yes, I have read the other thread on a similar topic, and no, an IP whitelist would not work for me. I still want this to be a public server, I just want to do some tests while nobody's around.
