DNS should definitely work (I *never* modify /etc/hosts for anything but the machine's own address). Remember that TCP wrappers is not resolving X to 1.2.3.4, but verifying that 1.2.3.4 is actually X. This requires reverse name resolution (the 'in-addr.arpa' DNS zones). Perhaps these have not been set up for X, Y and Z in your DNS. Test this by doing "nslookup 1.2.3.4" to see whether you get back X. > I also tried /etc/hosts.allow with "rexecd: ALL" but it didn't work. IIRC, TCP wrappers will do the name lookup regardless of what is configured in hosts.allow or hosts.deny, so if there's a name resolution problem then you'll still get delays/failures.
