    9 times out of 10 this is caused by libwrap (TCP wrappers). Some
    Linux distributions have "ALL:PARANOID" in /etc/hosts.deny by
    default, which means that any *client* whose IP address cannot be
    resolved to a hostname will be denied. If this is the case, then
    either take out ALL:PARANOID or fix your DNS so that it spits out
    hostnames for all of your client machines (if they're on a LAN).
