Yup, I had this problem.

I traced it to having "ALL: PARANOID" in my /etc/hosts.deny

Not sure where this came from as I don't use tcpwrappers to control
access to my host!

The PARANOID wildcard matches any host whose name does not match its 
address.

So you'll probably find it probably has something to do with reverse DNS
of the hosts your getting denied from not existing. As I did.

Mark.
