Logging and chat

[Michael-K3FEF]

Is anybody aware of any type of substantial logging for novasdr site access and relation between users in the chat and their IP address?  I setup logging in my gateway router, but I have no way to identify a user's chat messages to their IP addresses.  I'd also like to identify who is sending in the obviously malicious LONG url's and crashing the server constantly.  It seems chat messages disappear after a period of time from the small chat file, and I can't find any log files.
I was considering setting up a wrapper site in apache but that really messes with things, and the users can still figure out the novasdr direct access if they view the page source. :-(
