I repeat my initial question: Name a program which requires
Reverse Authentication on YOUR side. I know that some
sites will try to reverse authenticate you, but they really
only need to reverse-authenticate the IP that you're coming
from.
For example, we have a BUNCH of IP addresses that we
randomly assign to dial-up users. One of them is
209.140.61.160, which resolves to:
"209.1tnt1-160.highertech.net." If I *happened* to be that
person who got that IP address randomly assigned to me, I
couldn't be reverse authenticated to a particular machine
name on my system. For example, my home system is "slave1."
Try looking up the hostname, "slave1.highertech.net." It
doesn't exist.
The ONLY program I've had problems with authentication on
was IRC, and I fixed that by enabling the Identd daemon as
well as opening up that port on my ISDN router whenever I
run IRC (which is almost never! <G>)
