Yes, you are right. Some applications use double reverse DNS lookup to
enforce security. Since our internal IP is fake, DNS lookup takes a long
time. So I add an entry in /etc/hosts, and let nameserver looks for that
file before querying DNS server. This solves most problem, e.g. ssh/telnet
connection setup is instant. However, ftp still waits for
10-20 sec. I thought maybe wu-ftpd still query the DNS server.
