Could you please provide the exact version of tcp wrappers and what OS you are using. Could you also show the exact commands used. The details are very important because I tried this on two machines and did not experience any problem it worked exactly as tcp wrappers has always worked and I experience not problems with MySQL. > And number 5 is excactly the problem.

Thanks for the report but I have been unable to duplicate your problem.
