Hello We found a problem with MySQL that can cause serious problems when receiving connections from disallowed hosts. On our systems we can produce the problem by following the following steps: 1. Configure tcpwrappers to deny connections from everywhere to mysqld 2. Configure MySQL to accept connections from the network. 3. Start/Restart MySQL 4. Connect from a disallowed host. 5. Whilst the above is still "blocking" connect to MySQL on the machine itself. It should block until 4 has finished. And number 5 is excactly the problem. You would expect 4 to terminate almost immediately due to access denied or something and then to start authenticating 5. Instead, it locks up.
