Thanks for the response. I got some wireshark captures before it closed. Foolishly, I just thought it was a single encryption key. For some reason I did not even consider anything else. I did get some captures from the login so I can look at those and see. Since I thought there was a single encryption key all my other captures are worthless. Maybe I got a few during the same time I got the login capture.
If I can get the login to work and have LU actually start, I am hoping I can "make up" the rest. That would be another learning experience and I could make LU my way That may keep them from suing me since it would not actually be LU. I did see an email from LEGO to another person about making their own LU and LEGO said they could do it as long as they did not include the red LEGO logo. There may have been something else too. I will have to see if I can find that, or email LEGO myself.
Thanks for all the advice. I will definitely search for "server emulation." This may all be moot and I may not get anywhere with it. Hopefully I will learn something along the way.
Although, I now have another question. Does it not add more "stress" to the server to have to keep track of all the different encryption? I guess I should look through the MANGOS source code and see what it does before I start asking. I am guessing it stores them in the database. Sorry, I will quit typing and go look it up.
Once again, thanks for the reply.
Thanks,
Patrick
