At work, I regularly have to set up new IPSec tunnels to our
customers. It's usually a tedious process and requires a lot of
inter-human communication.
Now, imagine other protocols begin as fragile as IKE. Imagine HTTP or
SMTP failing most of the time. Every other web page would be
inaccessible for you. How about mail servers that refuse to talk to
each other because they can't agree on whether they're using CR or
CR+LF as line endings. Just imagine stuff like that for a second.
Don't you think it's time for a major revamp? A successor to IKE?
I know, I know. It's never going to happen. People would have to buy
*new hardware* because they're all doing IPSec on some obscure
hardware appliance. Way too expensive.
This is *so* broken.
The entire computing industry is broken. We will *never* get rid of
all that old shit. IPv4 is going to stay forever, so is IKEv1 and
Windows XP. There's too much inertia. You can't replace all the hard-
and software. You just can't.
I wonder what's going to happen when UNIX timestamps overflow.
