Navicat for Linux can be downloaded from their website at http://www.navicat.com/. I do honestly think you'd be better off going back to Windows (Microsoft Windows, not X Windows (X)).
Why did you choose Linux anyway? Seems to me that you need something a little easier to use. Learning how to admin a Linux box seems a bit out of the scope of the EQEmulator project, and given the exposed nature of it, you're probably going to end up hurting yourself in the long run.
