Check your (reverse) DNS lookups and/or server. If the address you are
connecting from doesn't resolve properly, you'll be denied, due to the
following lines in the default hosts.allow:
# Protect against simple DNS spoofing attacks by checking that the
# forward and reverse records for the remote host match. If a mismatch
# occurs, access is denied, and any positive ident response within
# 20 seconds is logged. No protection is afforded against DNS poisoning,
# IP spoofing or more complicated attacks. Hosts with no reverse DNS
# pass this rule.
ALL : PARANOID : RFC931 20 : deny
I've had my DNS server drop out on me more than once, and each time I
get exactly those problems you mention with tcpwrappers. :)
