tcp_wrappers is joke security. Anyone using TCP wrappers and hostname-based
rules is braindead.

SSH does not require reverse DNS to operate properly.

Sorry, but this is just 100% wrong. I've set up Oracle on many boxes and you
don't need any DNS at all to set up an oracle DB. In fact, I tell our DBA's
to use IP addresses in their TNSNAMES.ORA files because I don't want the DB
depending on DNS.

Too bad for you. Maybe you should get better ACL's.
