Thank you for the reply, Falko.
I apologize for not being more clear in my first post. I have already implemented the allowed-hosts suggestion to no effect, and my IP address is not in any of the files in WORK_DIR except for that one (allowed-hosts).
Please note that, as mentioned above, I have also included my IP in hosts.allow, which is having no effect.
Could this be a tcpwrappers issue of some kind?
