Mobile ip provides a communication system for md5sum 'secured' pieces of
information to notify a remote machine to update it's iptunnel/ipip devices.
The client on the 'mobile host' changes both the mobile host's tunnel
devices and the remote machine's.
I cannot use this because I have a stupid firewall, and even ip tunneling
doesn't work. (at least not my dialed up machine to another machine on the
same dialup; however, while I cannot nfs mount anything over the dialup, I
can export nfs. So maybe I could try iptunnel with my brother who has an
unrestrictive dialup.)
I was thinking along the lines of, even if it were a severe hack, would it
be possible to have my machine somehow securely notify my brother's machine's
kernel that the old '131.151.253.7' is now '131.151.253.91' and that any
connections still open should be re-engineered to go to 131.151.253.91,
and have my machine do the same...
...just as an example of what I was trying to ask 'if' it would be possible..
I have a sneaky idea that the answer is most likely 'Sure, you can do anything
with software'...but that it would never be considered secure enough to put
into the actual networking sources..
Just ramblings of someone brainstorming.
